Enabling the Feature on the Siebel Server

This feature is disabled by default because at least three machines must be configured to support the Coherence cache, which might take some time. There are several steps to enable this feature when you're ready. You can enable the feature at the enterprise level by setting a hidden enterprise level parameter in Server Manager or the at the UI level.

To enable the caching feature at the enterprise level:

1. Sign in to the Server Manager on the Siebel Server machine.
2. Run the following command:

   change entparam EnableOMDistributedCache=True

   Enterprise Parameter Name	Suggested Value
   EnableOMDistributedCache	True - enables the feature across your Siebel enterprise. False or no parameter defined - disables the feature for your Siebel enterprise.

3. Restart the Siebel server.

Note: Siebel’s connection to Coherence can be verified from the application UI under Help > Technical Support > Cache Status. The status is displayed as Connected when Siebel successfully connects to Coherence, Not Connected when the connection fails, and Not Enabled when Coherence caching is not enabled. This information reflects the system’s current runtime status.

Additionally, when the Siebel service or components start successfully, the initial Object Manager (OM) log shows a successful connection to the Coherence cache named <CacheName>, as shown below.

The following log snippet shows a successful Coherence connection.
