GRTgaz new Information System on Oracle SuperCluster

This testimony from Mr SĂ©bastien Flourac, Head of Strategy for GRTgaz IT, concluded the last week SPARC Showcase event. Mr Flourac highlighted why he selected an Oracle SuperCluster, Engineered Systems, over a more traditional build it yourself approach, that he also studied.

Due to EEC regulation, GRTgaz a subsidary of GDF-Suez, has to be externalized including of course all its applications and existing IT in less than 2 years. But, of course, the current platforms are shared with other GDF-Suez services, which means for GRT gaz, that they have to build entirely a new platform to migrate their existing application with the lowest associated risks. As a major part of the technologies supporting GRT gaz applications was running on Oracle Database and Oracle Weblogic, either on IBM AIX or SPARC Solaris, GRT gaz had a closer look on what Oracle has to propose to simplify Oracle software on Oracle Hardware, compatible with the existing GRT gaz environment. And it became obvious to Mr Flourac that Oracle SuperCluster was the best fit for his project and for the future for several reasons.

Simplicity and lower cost

With Oracle Engineered Systems, all the complexity and cost of traditional build it yourself solutions has been taken care of at Oracle Engineering level. All the configurations and setup have been defined and integrated at all levels (software, virtualization and hardware) to offer the best SLA (performance and availability). This was concurring to simplify its externalization project, and was also bringing additional benefits on the storage layer for the future.

It was the best financial scenario in their project context.

Lower risks

Not only does the SuperCluster offer the best SLA by design. It also provides a very important feature in this complex applications migration : a full compatibility to run existing Oracle software versions. This was very important for Mr Flourac to avoid in his project to do both : migrate and upgrade.
It is also providing :

  • an integrated stack of Oracle Software and Hardware
  • an upgrade process tested by Oracle
  • a better support of the entire stack

Build for the future

Oracle SuperCluster provides to GRT gaz a consolidated, homogeneous and extremely scalable platform, which not only enable this externalization project but also will be able to host the new business requests.

With this new platform in place, Mr Flourac already knows that in the next phases he will be able to leverage additional integrated and unique features that running Oracle Softwares on Oracle SuperCluster provides:

  • Exadata integration and acceleration for Oracle Database starting with 11gR2
  • Exalogic integration and acceleration for Oracle Weblogic starting with 10.3.4

Of course the SuperCluster is a key enabler, but such a project requires also a team to manage the migration, the transition and the run. This is done through the support of Oracle ACS (transition), Fujitsu (migration) and Euriware (run).
