The base products (or "using" products) that use CA Datacom/AD as their data repository are shipped with default database IDs (DBIDs) for the product. While many clients will elect to use the default DBID, other clients are change this value to something else. In order for the Datadictionary/CXX CATALOG functionality to work correctly, we will review the definition and note any differences from the default that could cause a problem for the application.
In this case, the message indicates that although we shipped and expected a default of 601 for the DBID, we actually encountered DBID 603. This is a notification message, and if you expect to see this and know that the "NEW VALUE" is correct, there is nothing further that you need to do.
