Oracle Exadata Database Machine is our enterprise standard for SQL databases. My department has a large application on Sybase ASE 16 and we evaluated a number of platforms to migrate onto from Sybase. After reviewing MS-SQL, SAP HANA, IBM DB2 and Exadata, Exadata emerged as the winner. We put in place a two year project plan to migrate about 50 TB of data, 24 databases * 7 instances, 8000 stored procedures and about 1,500 tables. Our business problem we were solving was to collapse 7 instances of our application into 1, eliminate multiple copies of data and migrate off of dedicated hardware, moving to our enterprise Exadata offering us the database as a service.
- High Speed Computing
- History Tables
- Implementation of temporary tables
- SQL Developer attempt to convert T-SQL to PL-SQL could be better
Recently our client's Oracle database servers were migrated to Oracle Exadata Database Machine. Due to this migration, downtime has reduced drastically. Previously we had downtime during Oracle patching but now there is no downtime. The Oracle Exadata Database Machine is faster. It supports scripting using bash. The computing speed is high. The performance of queries has increased a lot. Our business is running smoothly due to this.
- Zero downtime for Oracle patches
- Faster I/O as compared to non-exadata
- Scripting using bash and sh
- Patching is complex because of zero downtime
- Configuration is complex
- Hardware needs improvement

Exadata does better than most
Exadata is used extensively to support various business intelligence teams. It allows for high speed delivery of data as well as fast replication to other environments. It also allows for a siloed approach for delivering discrete database solutions. As an architected solution, we can quickly realize features and components that will be highly utilized as well as those that will not.
- RAC/clustered database technology
- RMAN duplicate and cloning
- Full sh/bash/ksh support
- Generally faster i/o throughput versus non-exadata
- Patching can often become quite involved and convoluted. It should be more transparent and straightforward.
- Storage metrics can be difficult and time consuming to obtain.
- Basic administrative functions can be hard to repair when discovered.
- Vendor support can take a while to obtain. Generally several attempts are necessary to reach the right area of vendor expertise.

The best you can get!
I have been using Exadata for about 8 months and have been loving it. Most of the time it is used by the BI applications team and we don't get any bad feedback from then. If you want the ORDM, go for it. It's fast and effective. Migration to the database is easy as well.
- Fast.
- Effective.
- Easy to migrate.
- Can be time-consuming in the beginning.
Our organization utilizes Oracle Exadata Database Machine as analytical database system. It is primarily used by business analytics and reporting units throughout the organization. As an enterprise grade database appliance with optimized computing platform, it enables users to execute aggregation of huge data faster than using commodity servers. Thus it is a dependable system to generate mission critical reports.
- Customize-able for specific functionality optimized for combination of online transaction or analytical processing.
- Ability to serve mix workloads with resource management feature enables prioritizing allocation for certain workload.
- Scale-able on-premise with compatibility for cloud deployment offers flexible solution for organization considering to transition from on-premise solution.
- Integrating with different types of databases can be a challenge
- Having a hardware platform optimized to run specific database software surely comes with a price
- Single vendor to support same hardware and software will make migrating to different hardware and/or software become a hassle

Built to run mission-critical databases
We run all our mission-critical databases on the Exadata platform. It provides us the extreme reliability and availability to achieve our extremely high SLA's.
- Availability.
- Performance.
- Security.
- Time to provision - It takes a whole village to provision a brand new Exadata. Would be great if the time to provision could be decreased.
It is used throughout the organization as the primary reporting database for patient data. Multiple instances are running, one for each region/state.
- Group shared space offers easy management and flexibility.
- Consistent response times, faster than the vendor replaced by Oracle.
- Oracle SQL Developer is full featured and intuitive for accessing Exadata.
- The learning curve for syntax (aliasing, dates, etc) is steeper than some database vendors.
- Initially had issues with response times but this was resolved with some configuration changes.

EXADATA
It's the best platform to run Oracle Database. You can consolidate all your DB workload to Exadata and it will perform much better than other platforms. We got almost a 3-5x boost on Exadata. It is one of the best and easy to manage platforms and gives full control to DBA. Backup and restore of Database is also easier, simpler, and faster.
- It runs analytical workloads much faster.
- The HCC compression helps to reduce the storage cost and increase storage efficiency
- Ideal platform to consolidate database.
- It's difficult to find the cons.
- Entry cost may be high but if you compare overall cost with performance, then it's not a big factor.
- It does not support legacy database version.

You aren't on Exadata? You're killing me smalls!
We are using it for our PeopleSoft application across the enterprise. This addresses some of our performance issues. Our payroll calcs went from 25 minutes per calc to 6 minutes greatly improving our payroll confirm. Better performance for our database backups.
- Speeds up backup and restore.
- Improved performance for payroll processing
- Platinum support and proactive monitoring of database hardware
- Batch processing performance improvement.
- Platinum support patching has suffered lately in performance of the patching event
- Cost for additional applications such as RAC
- Cost of the hardware and support

Performance, scalability, fast, installed: this is Oracle Exadata.
The most valuable feature of the solution is that it is durable. It is a highly relevant option with extreme performance. The extreme performance is one of the key features when you're using Exadata. There are known points that you need to take care of, simply "beware of update".!
I implemented a data warehouse on Exadata. Before this solution, we were aiming for this to be completed by 8 a.m., when our ETLs would finish. With the help of Exadata's special features, this was reduced to 3 a.m.
This solution allows us to bring more data within the same time period. It provides us with more subject areas that provide more reports to our users. Our ETL times reduced to 65%, then to 50%.
- Oracle Database : Deliver industry-leading security, high availability and scalability with Oracle Database, which has been significantly enhanced to take advantage of the Oracle Exadata Storage Servers.
- Exadata Smart Scan : Improve query performance by offloading intensive query processing and data mining scoring to scalable intelligent storage servers.
- Smart Flash Cache : Transparently cache 'hot' read and write data to fast solid-state storage, improving query response times and throughput. Exadata systems use the latest PCI flash technology rather than flash disks. PCI flash delivers ultra-high performance by placing flash directly on the high speed PCI bus rather than behind slow disk controllers.
- Hybrid Columnar Compression : Reduce the size of data warehousing tables by 10x, and archive tables by 50x, to improve performance and lower storage costs for primary, standby, and backup databases. Query high, query low, archive high and archive low.
- Infiniband Network : Connect multiple Oracle Exadata Database Machines using the InfiniBand fabric to form a larger single system image configuration. Each InfiniBand link provides 40 Gigabits of bandwidth–many times higher than traditional storage or server networks.
- Petabyte Scalability : Easily scale data warehouse to support enterprise data growth.
- There's nothing bad to say about Exadata. It's stable, durable, and always up and running. My DBAs do online patches and online backup.
- I would like to see more database features and maybe more archiving features, because we need to do data archiving. I would like to see additional database memory.
- It could be cheaper. :-)

Exadata - It's more than one could ever expect
We used Exadata across the entire organization. We needed a super high-performance database platform for Oracle - and Exadata was exactly what we needed. While the initial cost and learning curve were a bit steep, the performance improvements in all our database applications were nothing short of phenomenal. If we could have afforded to switch over entirely to Exadata we would have had stellar results. For those database applications we did not place on Exadata it was painful to know there's a better platform and way to go. If budget were not an issue we would have done so. It's almost impossible to value the smart scan technology and cell offloading until you see it in practice. The technology delivers on every promise and in general, is far better than one expects.
- The smart scan and cell offloading churn through massive amounts of data in a far more efficient and timely manner than any other Oracle database platform option available.
- We did not have to change any application code to deploy on Exadata. We never allowed optimizer hints in our application code so we had zero issues when we upgraded.
- We actually were able to consolidate many databases onto a single Exadata box - far more than we had ever expected.
- I wish Exadata costs were just a little lower to overcome new users initial price shock. But once you see it in action the issue disappears.
- I wish the Exadata technology were available on non-Oracle hardware/servers. In theory it should be able to be done on other servers, but it's blocked by Oracle it seems.
- The new Exadata Express in the cloud is misleading, it does not have full smart scan capabilities. So people who try to experiment with Exadata first on the cloud may not see the real benefit and not understand why.
