Cluster Technology Support

High-availability solutions, such as clustering, are recommended on critical components. Oracle Global Customer Support will accept service requests from supported customers on clustered environments under the following support program:

• You must make sure that clustering is supported on each Siebel Server component. See Siebel Deployment Planning Guide for more information.
• You must also make sure that the server hardware operates with the supported server operating systems and clustering solutions.
• Cluster vendors are responsible for ensuring that the clustering solution is transparent to the Siebel application. Raise any cluster-specific issues with the cluster vendor.
• Oracle Global Customer Support will not duplicate a your environment by using a specific clustering product, but will investigate the reported behavior on a platform specified in this guide. Oracle Global Customer Support reserves the right to ask you for a reproduction on a system without clustering if it has reason to believe the reported behavior is caused by the clustering itself. In this case, you work with the cluster provider.
• Oracle is not under any obligation to make changes to Siebel products in order to accommodate specific clustering platforms. Under this program, clustering products are expected to be transparent to the application.

Should you decide to use clustering technology with Siebel products, Oracle strongly recommends that you conduct thorough preproduction tests.

Clustering is critical for the high availability of the Siebel Gateway Name Server, Siebel Remote Servers and the Siebel Database Server, Siebel File System, and certain other Siebel components. Clustering is also recommended for any application server that is not load balanced. For more detailed information about clustering with Siebel products, see Siebel Deployment Planning Guide.
