"Oracle 12c in AWS Cloud"

What do you like best?

The ease of setup in Amazon Web Services makes Oracle 12c a solid choice for Relational Database needs, along with tools that we are used to having like Oracle SQL Developer. The clustering of 12c gives us reliability, failover and confidence that our data is in good shape.

What do you dislike?

Was a bit difficult to get security group rules in place from Amazon Elastic Beanstalk after we had setup Oracle RDS with public access. We had thought that meant public within AWS as well, but that's not the case. It didn't take too long to find the security group which needed changed though, and after that we got to focus on our implementation.

Recommendations to others considering the product

It's a powerful and reliable relational database system that brings many features to the table and maturity of Oracle's well-developed product.

What business problems are you solving with the product? What benefits have you realized?

Storage of a mission critical product we are delivering and benefits of having a team thats used Oracle Database for many years and a code base to integrate easily with 12c.

"Oracle 12c works perfect for and stable big company with hard database structure"

What do you like best?

I like this software because i been using it for years, since oracle 10 and i'm experimented on it, for me its easy to use. It have been improving each version, right now is on top of database, fiable, good enterprise support and has strong security, easy way to do querys.

What do you dislike?

Oracle is one of the biggest and more stable database, but it's a kind hard to learn how to use it and administrate it. its becomes involved with many librarys and files on the operating systems so you will have to know a good knowlodge of oracle and the os.

Recommendations to others considering the product

The new oracle 12c is always getting updates and patches for improve their functionality and security, it can be used for little, middle, big and very big databases, if you are looking for a new implementation or migrating to oracle is worth it, it is a little hard to understand and get knowledge, but after you got it, you will have speed on the querys and security of your data.

What business problems are you solving with the product? What benefits have you realized?

I'm actually working in a big company that has an Oracle 12c database of 12 terabytes, it is hard to administrate and critical for the business if it does get down, works perfectly with aix and can be boost with powerha or oracle rac, its important to be with oracle because you have big support and the fiability that the database will always improving their performance.

"Best and Most Versatile Database"

What do you like best?

I love the quick and easy SQL. I know its not 100% standard, but outer joins with (+) are so much easier to read than "left join ... on ...". It is also easy to optimise and there are loads of parameters for all types of circumstances. I also like that I can set up DBLinks to for example SQL Server and write Oracle SQL that works against SQL Server. And I like the PL/SQL. One can write detailed and complex programs inside the Oracle database and its amazing how quickly they run.

What do you dislike?

Oracle has got very big and it is difficult to keep up to date with all the different developments. I focus on the Oracle PL/SQL programming and I use Delphi for the front end. At the moment I am learning how to do REST inside the Oracle database, and the documentation and set up is rather complex and it is time consuming to set up something that shouldn't be so complex. Oracle SQL Developer, the free DML and DDL tool that comes with Oracle is good, but slightly buggy and I much prefer Toad.

Recommendations to others considering the product

A great database. Easy to use, tune, debug, work with. Might seem a bit pricey, but IMHO it is worth it. And everything is free at development time, for as long as you need, which is important for me.

What business problems are you solving with the product? What benefits have you realized?

Accounting, Incentive and Loyalty, Call Centre, ERP, Everything ...

Quick development, easy to work inside the database easy to debug with Toad.

"Sr. Oracle Database Engineer"

What do you like best?

Oracle software provides great granularity in setting up the environment as per our needs and requirements. Customizing the solutions based on the problem areas comes with great ease and performance.

Performance issues could be easily found out using the tools like OEM and profiler options. Crontab allows us to make sure that all the jobs are properly schedule.

What do you dislike?

There isn't much that I dislike with Oracle. It would have been great to have the GUI on the Oracle similar to SQL Server management studio to manage the databases much efficiently and automate lots of stuff more efficiently and faster. Re-inventing the wheel kind of scenarios are some of the examples that we could have eliminated if we would have had a comfortable GUI tool to run on.

Recommendations to others considering the product

It's a great product and perfect fit for the Production environment for Mission-Critical databases.

What business problems are you solving with the product? What benefits have you realized?

We are utilizing the Oracle databases as a backend to Support Linkedin.com customer facing website. We have one of the largest GoldenGate implementations at LinkedIn having multi-colo setup. This is setup across 4 Datacenters across the Globe to provide high availability. We also have Active DataGuard setup across all the databases on all the colos to provide read traffic their dedicated instance. Also, having the nodes used for the Database backup and recovery purpose in times of disaster.

We also have the downstream functionality and support to our downstream customers like Teradata, Hadoop and Reporting environments to do near-live analytics of the data and run business critical reporting which goes to the Senior Leadership and Board level for analyzing the company's performance, objectives and goals.

We also have the custom scripting and Audit on top of our existing configuration to support what we already been provided by Oracle.

Automation using shell, perl and python scripts have been of a great deal using Oracle to setup lot of jobs which perform routine DBA tasks.

"Good solid database just a bit complex"

What do you like best?

Oracle is great for being used with certain products. The setup is fairly straight forward and creating your database is really simple. Once the database is in place there's nothing you really need to do as the system jsut works. There are a few extra tweaks you can do such as enable the Oracle Web Console, this is really useful as it will allow you to update any dbf files and associate them correctly. You can also tweak the memory usage to make your oracle system perform much better.

What do you dislike?

I really dislike how you have 2 zip files and within those zip files there are other zip files. you then need to move files from one extracted folder to the other extracted folder, this just makes things complicated. The backing up of the system is not very straight forward, you can use rman but you can't do this on a schedule, it is also not clear if spf files have to be created each time. The Oracle Web Client should also be enabled by default, its straight forward enough to enable yourself however if this was something that was done via installation it would make life just that little bit easier.

Recommendations to others considering the product

If anyone is considering this for use within the business make sure that you read the installation guides and help guides prior to putting this in your environment, especially if you're a newbie!

What business problems are you solving with the product? What benefits have you realized?

We use oracle for a DLP system, we are seeing benefits when it comes to storage, and it is actually doing a good job.

"The best relational database"

What do you like best?

Hands-down the best relational database on the market, if not considering the price part. Stable relational database since version 9i. With 12c you get lots of features for free, lots of work done specially in optimizor so that only Oracle can handle queries of that complexity.

What do you dislike?

With more automation or artificial intelligence as they named it, there is obvious overhead. To make things easy, evaluate what your application really need and disabled things you don't need. The license model is very complicated, really need an expert in your organization to work on it.

Recommendations to others considering the product

Hands down the best relational database on market, if cost is not a concern.

What business problems are you solving with the product? What benefits have you realized?

Money related transactional database systems. A stable system that just does what it's programmed to do, high available, low latency, no data loss, no corruption, no custom complaints.

"Oracle Database 12c for Business that Supports Clientele"

What do you like best?

I like all the features of Oracle 12c. Its performance, flexibility.,Advanced Index Compression, Full Database Caching

What do you dislike?

Technically I do not like the price of the 12c other than Price feature. Oracle is one of the biggest and more stable database, but it's a kind hard to learn how to use it and administrate it. its becomes involved with many library and files on the operating systems so you will have to know a good knowledge of oracle and the OS.

"Oracle Database 12C review"

What do you like best?

I could say that there are lot of things in oracle 12c which I likes the most, but one of the quick thing comes to my mind is the Enhanced DDL Operations feature of 12C, which no longer require blocking lock operations and thus allow us to drop the index online and thus saving a lot of time and efforts of a technical person. Another key feature with 12C is their Multitenant Architecture, which introduces container databases (CDB) thus allowing zero, one or many pluggable databases. With this feature, it would be really easy for a Database administrator to have a CDB, with all necessary information , instead of having multiple DB’s architected differently and thus managing them a piece of cake of them.

What do you dislike?

one of the most irritating thing about using oracle product is their support levels. It is really easy to log a call with Oracle, but very hard to get a solution. In my personnel experience, I have seen that once the service request is open , it is a pain in ass to make the level 1 engineer to understand our problem, as the solutions they recommend is generally already applied by the user and he needs some priority and senior person to work on his issue, but they follow strict protocol, which sucks the users experience.

Another pain area is that with everybody getting in virtualization solutions for their business, Oracle will offer very limited guidance on how to properly apply database licensing metrics for non-Oracle virtualization software.

Recommendations to others considering the product

From my experience, I would recommend every database administrator to use this product, as apart from his robustness, it is very easy to use and configure as per our applications requirement. Moreover, its fine tuning is easy and thus it could be customized as per your requirements, especially while in cloud native applications.

What business problems are you solving with the product? What benefits have you realized?

the oracle 12C provides a lot of enhanced features which allow us to realize our business goals, like I said earlier, one of the key feature of container databases are extensively used by us for a seamless aligning our business cloud native applications with oracle databases. Another simple feature of 12C, where they have increased variable character size limit from 4,000 to 32,767 bytes is used by us in our new big data applications, where large character size is a common norm these days.

"Max reliability for transactional tasks"

What do you like best?

Oracle 12c has reached the maximum reliability and availability thanks to the chance to deploy a cluster environment by shared cached. Keep in mind that previous version , as all relational database, suffered from scalability and availability.It is clear that it can't replace a NoSQL database as soon as data are from different sources as unstructured or semi-structured data.

What do you dislike?

Learning curve,especially for those are approaching to Oracle for a short time is a bit long. In fact there are many aspects to care about ,such as policy management, security, administration and auditing.

Recommendations to others considering the product

My recommendation is : If your business requires high availability , efficiency , professional support needed to guarantee a high quality of service .Then you have to go straight Oracle 12c, otherwise you can save money go for much less expensive solutions in terms of license.

" Analysis and development of information systems with database management"

What do you like best?

I use Oracle Database as part of my work, since, I support an administrative management system that uses to store Oracle 12C data. What I like about 12C is the option or "Invisible Columns" mode, which allows you to hide the change until we want to publish it, the mytable option that allows you to create a table in two steps and the addition of a field in invisible mode are of the options that I like.

What do you dislike?

As a specialist and consultant in the area of ​​IT and with experience in Oracle Database, the biggest drawback is perhaps its price. Even the personal licenses of Oracle 12c are excessively expensive, in my opinion. While we know that we can download much of the developments of the company, it is also true that we can not access the services of My Oracle Support or have available all the programs and updates

Recommendations to others considering the product

"Motor de base de datos muy potente"

What do you like best?

Las bases de datos de Oracle son muy potentes permitiendo un gran poder de computación, haciendo que gran parte de la lógica de computación sobre los datos del sistema sean derivados al motor de la base de datos y que este sea quien tenga que hacer el tratamiento de los datos, permitiendo liberar a tus aplicaciones.

What do you dislike?

El entorno o instalación pueden llegar a dar problemas en ciertos entornos, por problemas de puertos o que después de bastante uso se corrompan los datos, algo fácilmente solucionable mediante la realización de copias de seguridad diarias.

Recommendations to others considering the product

La gran capacidad de su motor para el tratamiento de los datos, el tratamiento en lenguaje SQL es bastante más efectiva.

"Pluggable Database Very useful"

What do you like best?

One of the most novel features I have observed from 12c is the plug-in database (PDB) usage characteristics which works as a portable collection of one or more schemas, objects, etc., and in turn as a separate database. This offers great utility to the DBAs in their planning, management and maintenance activities saving costs and time to the client. The added improvements in this version such as memory management, Increase in data volume management, Friendliness of Enterprise Manager Cloud Control, management of database in the cloud, and other attributes for administration, Planning and control and management Database

What do you dislike?

I have observed with concern the deterioration in Oracle with the support in MOS. Throughout the time in several years, I have seen and received diverse opinions of colleagues in relation to a significant decrease in the quality of service and the responsiveness of their support team to their clients.

Recommendations to others considering the product

The innovation, versatility and robustness of the product combining the number of added improvements in this version such as memory management, increased handling of data volume, friendliness of the Enterprise Manager Cloud Control, management of the database in the cloud, and other database attributes that justify its positioning in the marke

"The first database designed for Cloud Computing"

What do you like best?

I started in the world of SMBD using Oracle in version 9i and then started as administrator in version 11g, it was very easy to adapt, in version 12c drastic changes were made but they are great especially the multitenant architecture and pluggable databases data that allows you to consolidate databases on a single server at the same time and keeps them separated from each other. This new architecture allows the sharing of SGA, CPU and other resources, greatly reducing the amount of memory and CPU required.

In our organization where there are variety of versions of oracle for different applications, this version 12c and pluggable databases will facilitate the administration and update of patches

What do you dislike?

Technically I have not dislike, alone the price, but it is worth the investment

Recommendations to others considering the product

I would recommend it for companies that want a secure database, quite robust, reliable and if they think about using database services in the cloud it would be great.

What business problems are you solving with the product? What benefits have you realized?

Since we have a variety of applications in different versions of Oracle, we are evaluating the impact of migrating to version 12c and using the pluggable databases with the version of Oracle that are required

"Great and traditional Relational Database"

What do you like best?

I have started using Oracle DB since its 9i version. It loved this alot. A great tool for Database management and its scalable as well. It has very great feature of timely backup which I like most. Security is always the first priority for them. I really had a great experience with this tool.

What do you dislike?

It is very heavy load tool. It requires more system specification to operate. If we talk about pricing, it is bit costlier than other competitors like google or AWS. These are the only disadvantages I noticed so far.

Recommendations to others considering the product

I will surely recommend this to others and our colleagues as well to use this as their primary db for application. The effort which Oracle made to develop this great tool obviously it should reach to everyone.

As per the client application model, I could not share the screen shot of the application due to security reasons.

What business problems are you solving with the product? What benefits have you realized?

If we talk about the huge client application which has large number of customer records, there needs a db which can handle large number of records with its scalable behaviour, Oracle comes first in mind. Oracle is the king in database management with full of security. It is a great tool by Oracle to work on.

"12c: Clustered beast of cloud."

What do you like best?

Oracle 12c has helped us lot by cutting down limitations that we were fetching currently in traditional RDBMS.

12c has functionality of plugging databases (PDBs), where we can form master slave architecture and run multiple DB from single master. Cool isn't it?

Second cool thing, it supports JSON. which is quite helpful if you have application with REST architecture.

What do you dislike?

I don't see there is something to dislike about 12c. Yes, cost is definitely one of the factor where any organization needs to evaluate if it's helping them go positive or not. Because cost of 12c itself and device on which it runs are relative. Which definitely is high. But, again as i said, it would be totally organizations call.

Like is said above 12c has pluggable feature. But, again in order to use it effectively, you need lot of preparation. For ex:

All cluster DB must be configured to handle the resource requirements in accordance with PDBs that you are going to manage, else you will have to shutdown to reconfigure and restart the Cluster DB and all the PDBs. Additionally, you need to keep in mind small things, e.g. container, and all PDBs, should be running on same character set. Hence, it's better to switch to Unicode.

12c is definitely a beast which needs proper care to keep running smoothly. Of course, all the beast do. ;)

Recommendations to others considering the product

Definitely go ahead and opt it. PDBs & CDB will overwhelm you.

What business problems are you solving with the product? What benefits have you realized?

I would sum benefits to 3's. Scalability, Security and Stability. Pluggable database of course has helped lot. It's quite a state of art. It has helped lot in managing & reducing time and effort for database upgrades, backup, recovery, etc.

"Good for clustering and full database caching"

What do you like best?

I have dabbled with many databases for the enterprise and organization over a period of time and i strongly feel this is the best database one could ever get because of its scalability and aggregation, and surely the best relational database for large scale application servers and performs well under a heavy load and cheap,store retrieval options are easy and more flexible to create triggers and also create partitions and also in terms of backup and recovery it stands out all the time

What do you dislike?

There are some issues which i really hate one being the restricted PGA size ,table level recovery in recovery manager (RMAN),multiple indexes on the same column which takes quite a bit of a time inorder to get there and also fetch the data effectively and temporary undo in and outs and online migration of an active data file which takes quite a bit of a time and also sometimes session logging and tracking is a hassle here

Recommendations to others considering the product

I would prefer it just for the uniqueness and robustness this database has to offer and also the temporary cache storage tables all the time

What business problems are you solving with the product? What benefits have you realized?

For creating synonyms,ddl logging like create update delete statements it works faster and quite efficiently most of the times and temporary undo information takes a lot of steps to get it done but i felt that is effective for the business needs and we were able to save a lot of time in the process

"A powerful relational database with tonnes of features"

What do you like best?

If you have an enterprise version of Oracle, you get to use Oracle Enterprise Manager base version for free use. I have worked on multiple relational database but Oracle has been a great RDBMS. Oracle keeps adding awesome features and is truly the most sophisticated RDBMS in market right now.

What do you dislike?

I am not a fan of known issues caused by applying bundle patches released every quarter. It will be great if Oracle can make sure that we don't have to run into issues after applying patches and then having to rollback them. Although this is a very rare situation, but makes me a bit uncomfortable while doing quarterly patching.

"Oracle is very difficult to work with"

What do you like best?

Oracle packages are a nice way of bundling functionality, much like classes. They make it a lot easier to organize stored procedures and functions.

What do you dislike?

Everything of Oracle's is insanely expensive and more difficult to setup and administer. The Oracle databases require a lot more manual maintenance, and a lot more effort to setup initially. Additionally, we've been going through an upgrade from 11g to 12c, and it has been incredibly challenging. A number of legacy stored procs have stopped working. All of Oracle's products are very expensive and they never work well together. Oracle's support is terrible as well. At a previous employer, we had Oracle direct one of their customers to us for help, since we were an Oracle customer as well. The first customer called Oracle for help and their support just forwarded the call to us because we were working on something similar, instead of trying to support them.

Recommendations to others considering the product

Oracle is incredibly clunky and expensive. It's impossible to recommend it, even for core enterprise systems. Depending on the complexity of your database, you're going to need to get Oracle consultant time to help set it up, which is also insanely expensive. Oracle has mastered convincing non-technical people to choose Oracle.

What business problems are you solving with the product? What benefits have you realized?

It's our primary legacy database provider.

"Smoother experience coding vs. SQL Server"

What do you like best?

What i liked best about oracle database 12c is that it always felt more streamlined and made more sense than sql server from a UI perspective.

What do you dislike?

I disliked that there were less features and abilities to manipulate the tables as you can in sql server.

Recommendations to others considering the product

I would use oracle as a supplement to other data bases within your companies various other data base tools and not just as a stand alone application as it will be very hard to complete all the work that you might have to do if you need the data base to do other things besides load data.

"Oracle, still the database engine that can't be beat!"

What do you like best?

Robustness. It truly handles relational databases well, as well as all of the ancillary services you need for a fault-tolerant database environment.

What do you dislike?

Cost and marketing. Oracle has a high turnover in technical sales folks, or they move them around a lot. It seems I get a call from each new person and they are always trying to sell us something. We would prefer them to be more "on our side" helping us get our money's worth out of their product.

Recommendations to others considering the product

I have used Microsoft SQL Server and PostgreSQL. If your company needs performance and fault-tolerance that is proven, Oracle is the best choice.

What business problems are you solving with the product? What benefits have you realized?

Oracle is our back-end database that runs our mission-critical systems. We use Oracle RAC to provide fault tolerance because we really are a 24 hour shop. We have incredible amounts of data and Oracle has the performance we need.

"Oracle Db"

What do you like best?

Grouping Transactions

The ability to group several transactions into the same batch for processing sets Oracle apart from its competitors.

Microsoft's version of SQL is limited to executing each transaction individually in a sequential order. This gives Oracle SQL far greater scalability over sequential versions of SQL, which are limited to only expanding vertically. Vertical expansion can be significantly more expensive than horizontal expansion. Expanding vertically requires the addition of server memory, hard drive capacity and ventilation equipment. Oracle can expand horizontally by clustering transactions for more efficient processing.

Improved Performance

In addition to batch processing of transactions, Oracle offers other methods of improving your database's performance. You can use multiple servers to work on the same database with the Real Application Cluster feature. This can significantly increase your processing power for only the price of an additional server. Oracle SQL also gives you more options to fine-tune the operation of your database to suit the capabilities of your server.

Versatility

Oracle SQL gives you the flexibility of choosing to run your database in any operating system. Dedicated languages are only compatible with operating systems from the same manufacturer. For example, you can only run Microsoft SQL Server on a Windows-based machine. In comparison, you can install Oracle SQL on a Unix server and benefit from the reliability of Unix while keeping the standardization of SQL. Unix is less vulnerable to many common computer viruses, which keeps your information secure. Oracle SQL is also backward-compatible, so you have the option of upgrading in the future without losing any data.

What do you dislike?

Cost

The cost of operating Oracle SQL puts it at a disadvantage in comparison to other versions of SQL. The cost difference starts with the licensing fees, which may be up to ten times as high for Oracle. Because Oracle SQL is such a complex and highly specialized language, it can be difficult to find qualified database administrators to run your system. When you do find a suitable candidate, expect to pay two or three times more in salary than you would pay a comparable Microsoft or PostgreSQL administrator.

Difficulty

Oracle SQL is also more difficult to learn and operate than its competitors. A user-friendly version such as SQL Server is easy to install and set up with a minimum of customization. It includes five sample databases you can use as a framework for your own company's information. Microsoft also provides Visual Studio-based SQL Server management tools to help you modify the database's design, change the data it contains and execute queries.

What business problems are you solving with the product? What benefits have you realized?

We use Oracle to store our data. Grouping transactions, versatility and improved performance are some of the advantages of the Oracle db.

"Oracle Database 12 c Review"

What do you like best?

Ease of updating from ongoing forms (10g/11g) to empower expanded help application lifecycles. This is extremely basic to most establishments, since client re-testing will be limited, and existing authoritative aptitudes are utilized in the new form without a lofty expectation to learn and adapt. 12c is an entirely steady discharge. As far back as support in the early Beta cycles, we stressed to Prophet, our need to not return to stretched out bugfix cycles endeavoring to inspire an early discharge variant to work underway situations experienced in numerous past releases.12c's inner programmed execution the executives highlights have enhanced over 11g, with fewer re-modifications always happening enabling the database to adjust to changing interest prerequisites, (for example, OLTP amid the day, however, overwhelming OLAP around evening time) and not agonizing over the overhead of empowering highlights, for example, AMM (programmed memory the executives) or ASM (the capacity related proportionately) and viewing the database will in general battle with itself attempting to upgrade the settings.

What do you dislike?

12c is a feature-laden installation. The impression of the product (Prophet Home) alone is about 4+GB, with no information stockpiling included, which deciphers, as most new items appear to underline, into you're getting everything in one box. While the underlying Prophet All inclusive Installer experience can be as basic as picking one of 2 pre-characterized database layouts and navigating 5 [Next] catches, the hop to picking the third alternative (a Propelled Establishment) goes from those 5 screens to more than 35, which may overpower another client needing to simply introduce a database to help an acquired application. I'd by and by prefer to see Prophet transport pre-designed formats with its own applications to give new installers a choice of picking an application-improved adaptation layout to additionally accelerate the underlying setup process.

Recommendations to others considering the product

An incredible stage for any adv application, that must be versatile, multi-stage, and surely supporting a large number of data related innovations, regardless of whether Java, XML, advanced analytics, or high-accessibility.

"Oracle Database Review"

What do you like best?

Oracle is a well known player in the database space. I enjoy the reliability of the database so I know about the consistency of the data being stored in each transaction. The SQLdeveloper software is relatively easy to use as well.

What do you dislike?

I think the interface could be designed a bit better such that the specific tools to generate SQL, commit and rollback changes were better described and usable. Besides that, I wish the Oracle database was as fast as some massively parallel databases because a lot of our backend operations end up occuring in a different Postgres data warehouse.

Recommendations to others considering the product

You need to seriously look at the scalability of this product versus other products. Most of the world seems to use Oracle database and things haven't really changed over the years with SQL. Oracle seems to have a new secure cloud that is available for use nowadays so that's something that should be considered for deploying this database. I think the recommendations is such that users should try to run parallel 8 on the queries and ensure that any ETL jobs that exist in the workflow are threaded so that you don't have a big issue with running a specific query (DML or DDL) that takes a long time.

What business problems are you solving with the product? What benefits have you realized?

I am solving data quality problems with the oracle database. I write SQL and then test the SQL in the development environment. Then the SQL is run on the production environment to ensure data consistency for our client.

"Works well"

What do you like best?

Once you get it set up. Oracle Database almost (but not quite) runs itself. The only tim you need to mess with it is if you hit a bug or performance changes.

What do you dislike?

It is expensive, no doubt. SQL plan management is a moving target, but if you can get a decent plan locked in, you should good to go.

Recommendations to others considering the product

You get what you pay for. Don't let cost drive you away of another solution can't do the work that Oracle can. It does the work and does it well, for the most part.

What business problems are you solving with the product? What benefits have you realized?

Third party and custom internal apps are built on Oracle. Data warehouses (internal and 3rd party) are also built on Oracle. Disaster recovery using Oracle is a breeze. Leveraged our DR solution for clones for test and dev and works great.

This multiple databases are self contained and pluggable from one database to another database. The databases can be created on fly and drop or attach and detach from one server to another server

What do you dislike?

this is one of the biggest and more stable database, but little tricky to learn it and implement it which involved with many library and files on the operating systems.

Recommendations to others considering the product

Its a great product to use but please go through the installation guides and help guides prior to putting this in your environment, especially if you're a newbie!

By default there aren't a graphical user interface to work with the tables and insert and remove rows in a easy way like there are in MySQL and and its versions

Recommendations to others considering the product

It's the business database environment of reference. The support is the best.

"Great for many use cases"

What do you like best?

bullet proof - it is resilient to many failures, from hardware to different software pieces, which makes it an easy choice for an ACID database supporting large scale workloads

What do you dislike?

its costs - it includes a lot of features that you buy all together, but is possible that you don't need all that for your use case. Many people end doing a wrong comparison of their requirements against common open source databases and Oracle, when in reality they are just looking for the minimal covering solution for their needs at the minimun price.

Recommendations to others considering the product

It has a wide set of features, which could be much more of what a simple transactional DB requirement could need. So better to spend some time initially to weight how much the features you can use are needed and make sense for your budget.

What business problems are you solving with the product? What benefits have you realized?

Highly transactional needs over large datasets and concurrency, HA support, strong resistance against hardware failures.

"Simplicity in Databases"

What do you like best?

Oracle Database 12c is extremely simple to use. Once you find your shortcuts it becomes second nature to maneuver the database.

What do you dislike?

Oracle Database 12c has an issue with using the back button. You have to remember that you have to use the back button within the database and not the web browser.

Recommendations to others considering the product

I recommend that they fix the back browser button issue. Sometimes it slips the mind and it erases all work and information entered.

"Review as an Oracle Cloud Implementor"

What do you like best?

I like the ease of configurations. I like how it can be integrated with many other third party applications, as well as other solutions and offerings that Oracle Cloud suite offers. I like the user friendly interface that Oracle Cloud 12 offers. I have only worked within the Financial Cloud applications and the general ledger, as well as flow from receivables, payables is solid.

What do you dislike?

I dislike how it is slow sometimes, I dislike the complicated organization structures and business unit configurations. I also dislike the Oracle customer service, as they take SEV 1 service requests, not as seriously as I would like. Furthermore, software patches often mess up some configurations, as well as migrating data and confiiguration setups to different environments is difficult.

Recommendations to others considering the product

Think about the size of the business before setting it up, as cloud products have their down sides. It is a quick and easy product to deploy, also great to learn as Oracle University has Cloud courses to learn how to configure and set up the product in different modules. *Note to get certified in a module it is difficult.

What business problems are you solving with the product? What benefits have you realized?

Financials and accounting for companies in many industries. The benefits are best for medium to large sized businesses. Company also wanted a way to track their expenses from sponsors, as well as track capital projects such as real estate property, and employees computers. Benefits are ease of logging on anywhere and anytime, even if you are not on premise.

"Oracle Database 12c - A Solid Version"

What do you like best?

Oracle databases are extremely powerful and useful if you know how to use them properly. I've been using Oracle databases for many years, and this version is a solid, stable option.

What do you dislike?

It can sometimes be frustrating that the database cannot always determine on its own what the optimal execution should be for a query. Oracle has hints available for you to guide the execution path if you feel you can improve upon the default performance. There is even a hint that allows you to specify the database should mimic the optimization methods of a different version of the database (OPTIMIZER_FEATURES_ENABLE).

Recommendations to others considering the product

The 12c version of the database is definitely worth the hassle of upgrading.

What business problems are you solving with the product? What benefits have you realized?

We used the Oracle Database 12c to store and manage data for our organization across many different applications and environments.

Product that provides greater agility and scalability for company implementations. For a relatively short time I have been using this technology that helps to include various tasks especially in financial matters.

This version simplifies the path to cloud environments and provides efficient delivery of database services, among other advantages.

What do you dislike?

Interruptions in the system. Interruptions are caused due to database problems, such as running out of storage space due to increased volumes of data or a resource that is not available, such as a data set, partition or package.

Recommendations to others considering the product

Good way to optimize and automate the operations of the company reducing company costs and quickly putting various departments and increasing the productivity of the accounting department.

At least in my office, I still have to rely on far too many third party tools to get anything done.

"Oracle DB 12c Makes A Mark"

What do you like best?

Oracle DB 12c has a noticeable performance increase when processing data over earlier versions. Expanded capacity for tables and schema is a huge plus. This, in general, is a welcomed upgrade. We have three installs since 12c was released.

What do you dislike?

The upgrade is a bit painful. Not terrible if your are an Oracle Guru, however, if you don't have an experienced team member to perform the upgrade I suggest contracting it out. The other issue is they have moved some tool sets, like the beloved manager for example, out of Standard and into Enterprise only. This is a major bummer and a mis-step on Oracle's side in my opinion.

Recommendations to others considering the product

You do lose some tools... some good tools. Please do the side by side comparison so that you are aware of anything you may lose that matters to you. Also, do you due diligent before running the upgrade.

Oracle DB is one of the best DB software out there. We use it here at Spectrum on a regular basis with the Engineering team and are still learning how to use it, but so far we are big fans. Well done Oracle.

In the beginning we had a lot of challenges figuring it out; I admit the platform was a big confusing looking at it for the first time. After some adaptation and learning where everything is, within 2 weeks we all felt comfortable using it.
