Switching from the Embedded Database to an External RDBMS
For Integration Servers to participate in a cluster, they must share database components in an external RDBMS. If you installed an Integration Server with the embedded database, but now want to add it to a cluster, you must switch the Integration Server to use the shared external RDBMS.
To switch to a shared external RDBMS
1. In Integration Server Administrator, navigate to the Security > Certificates > Client Certificates screen, and make a note of the certificate mappings.
If the cluster already exists, create JDBC connection pools for the IS Internal and Cross Reference database components, and point the ISInternal and Xref functions at the shared IS Internal and Cross Reference database components. See Installing Software AG Products for instructions.
If those database components do not yet exist, create them and connect all Integration Servers in the cluster to them.
2. Run the migration utility pub.scheduler:migrateTasksToJDBC to migrate your scheduled tasks from the embedded database to the external RDBMS. See the webMethods Integration Server Built-In Services Reference for instructions.
Note: | This service migrates scheduled tasks only; client mappings and run-time data will not be migrated. |
3. In Integration Server Administrator, navigate to the Security > Certificates > Client Certificates screen and re-specify your certificate mappings. For instructions on mapping a client certificate to a user, refer to webMethods Integration Server Administrator’s Guide.
4. Configure Integration Server as described below.
