- Oracle application/middleware performance optimization
- Virtualization with bare metal performance
Exalogic has provided us and our customers with high performance Oracle Weblogic, eBusiness Suite applications and concurrent manager platform. Even with running in a virtualized configuration, the performance seen has been better than running on non-Exalogic physical environments. The ability to connect Exalogic to Exadata via Infiniband has also optimized performance between application and database improving application performance. This is particularly true for chatty weblogic applications or eBS large concurrent manager jobs like those related to advanced supply chain planning.
The administration of the VMs is cumbersome and lacks features that are taken for granted in other virtualization platforms – many administrative and availability features, even available in traditional OVM, are not available on Exalogic. This includes not having the ability to increase VM resources while the VM is online, or even being able to change CPU and memory sizes for a VM without recreating and cloning it. There is also no live migration feature available.
I've been using it for two and a half years.
There have been no issues with the deployment.
We've had no issues with the performance.
It's been able to scale for our needs.
The support on the Exalogic is much better than other, non-engineered Oracle environments. Exalogic comes included with Oracle Platinum Services – a higher level of Oracle technical support – providing Oracle access to the system and allowing for faster responsiveness and resolution to issues.
The initial setup has to be performed by Oracle or a certified partner. Stating that, the initial install and setup is straightforward and is completed in a few days.
As an Oracle certified partner, we implemented in-house. My advice is to utilize Oracle certified Partners, to do the implementation or utilize Oracle ACS. We have also had experiences with network conflicts in past Exalogic implementations. And much of the network configuration can not be changed without a re-install. My advice is to ensure the network addresses and information given in the Exalogic Configurator worksheet, filled out before install, is accurate and does not conflict with other addresses in the corporate network.
We compared commodity server based environments – but they were unable to match the performance of Exalogic.
Exalogic is an environment built for performance for Oracle middleware and application workloads. If you are looking for the best performance for such environments, at the expense of some ease of administration, then this environment is for you.
