DBNAMEMISMATCH, Database file xxxx (region (yyyy) referenced by shared memory (ID=zzzz) is not accessible. Ensure region is properly rundown
Run Time Warning: When a GT.M process attaches to a database and finds the corresponding shared memory structures already initialized, it performs integrity checks on the shared memory contents to ensure that they correspond back to the database file. When the shared memory points to a database file name that is not valid, this error is issued.
Action: This error means that the shared memory contents are corrupt; consult your GT.M support channel before proceeding further.
