Great performance database

What do you like best?

Oracle Exadata database has a very good performance and the best thing is that its hardware is optimised for the database services allowing users to get the best performance from it.

What do you dislike?

The biggest disadvantage is probably price because it's very expensive but if you are considering Oracle Exadata you probably have enough funds for it.

Recommendations to others considering the product

I would advice to hire an Oracle dba with in depth knowledge who has experience with implementing and administering Oracle database so that this person can configure the database correctly.

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

Oracle Exadata allows us to handle any kind of workload (OLAP and OLTP) on the same database server and respond to business requests without any issues. It allows us to run warehouse reports as well as analytics and batch jobs needed for the business.

Super Fast, great addition to Oracle world

What do you like best?

Queries that use to run for hours take only minutes now if not seconds on EXADATA. My company implemented about 2 years ago for our Maximo and Siebel services and recently our team (Datawarehouse) was able to migrate over as well and the performance gains are easily noticeable.

What do you dislike?

There have been many hiccups along the way and our current DBA team are not very familiar with the setup of the new system requiring our firm to hire outside consultants to assist in the implementation of it. We are still using them even now, but it is a lot more stable now then before.

Also migration is a bit of a hassle and we are still having issues with it

Recommendations to others considering the product

Be ready to have a firm migration path and have all stakeholders confirm that they will be available for it since it will hold up migrations if not everyone can do their part.

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

Migrate our 7 year old server currently running Oracle 10g to Exadata. It has been a drastic change in performance, helping the business retrieve metrics at a much quicker response time.

What Data Warehouse solution do you use?

Thanks for letting us know!

Exadata Rocks

What do you like best?

The sheer raw performance is nothing short of amazing. The separation of the database server and cell/storage servers results in a trul optimal architecture.

What do you dislike?

The initital purchase price is preclusive for many shops. You have to send your DBA's to some addituional training calsses and/or hire some Oracle consulting. Plus the hardware components like simple server fans cost ten times as much as X86 ones even though they look the same.

Recommendations to others considering the product

Factor in time for initial learning curve. Perfomance will exceed expectations even at first. But once you become more accustomed to Exadata you will tweak your databases to maximize even more.

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

Achieving the fastest overall database performance enabling us to meet all service level agreements (SLA's). We've also been able to perform database consolidation and thus reduced our server count and power usage significantly.

A must for Big-Data systems

What do you like best?

There are a lot of good things, but I would like to mention 2:

- Querying is fast, faster that any other system. This is because EXADATA can execute the queries in the Storage itself! It saves a lot of time of sending and receiving files.

- Thanks to its power, you don't need different OLTP/OLAP database instances. They can work in same DB without performance issues at all

What do you dislike?

The price. This system can be only afforded by big companies and for big projects.

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

Mainly use for big data project and, in general, any project that needs to have databases with millions of rows.

Intelligent storage, fast processing - next-gen system for high-volume transaction processing

What do you like best?

The end-to-end support provided by Oracle as everything right from the hardware to the software comes from Oracle which reduces the downtime and dependency on various vendors.Also, the configuration for all customers is identical which helps in keeping down the number of issues and a faster resolution if at all any issue arises.Also, the compression capability for Exadata is commendable.

What do you dislike?

The ease of use and the wide assortment of statistical functions is missing for it to be a complete data extraction and analysis solution. There are some performance issues with use of multiples views and CTEs in the same SQL query.Also, using SAS for analysis and Exadata for data extraction poses various challenges as data types and formats are different in Exadata then in SAS.

Recommendations to others considering the product

The improvements are huge over the legacy database but Exadata is not a complete data extraction and analysis tool. SAS will still be required.

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

Moving from legacy databases like SAND which were very slow and took ages to retrieve data, Exadata saves a lot of time in generating reports.

Great OLTP and Report performance

What do you like best?

Exadata Flash Cache, Smart Scan (for tables without indexed columns), HCC for Archive Tables

What do you dislike?

Relatively low initial memory for total capacity

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

We implemented and migrated core banking applications to the Exadata Database Machine. Exadata has become a suitable platform for our new basic insurance applications.
