It is important that you choose unique names for the schema names and SQL IDs in the DB2® tables.
The DB2 tables must have uniquely-qualified schema names to coexist with other WebSphere® ESB for z/OS® cells in the same DB2 subsystem. You can set the current schema or SQL ID value using the administrative console. On the administrative console, click Data source > Custom properties to display the definitions you want to change.
SET CURRENT SQLID = 'B6CELL';
Each of the SIB databases requires unique schema names for its tables, because the same table names are used for all Buses. These same schema names must also be set in the SIB Messaging Engine Data Store properties. See Messaging engines in the WebSphere Application Server for z/OS information center.
