If the realm could not be extended, due to an error reported by DMS, the following message is output together with the relevant DMS error:
UDS0700 UDS RESOURCE ERROR (&00) (&01) (&02)
If a DMS error occurs during realm extension or if the realm has already reached its maximum size before extension is attempted, the DBH suspends online extension for the relevant realm. This prevents constant failed attempts in the current part of the session to extend this realm. The DML statement which triggered the unsuccessful realm extension may then still be completed successfully, if there is still sufficient storage space in the realm to process the DML statement. The relevant acknowledgement is contained in the status code as usual.
If online extension for a realm is suspended, the following message is output:
UDS0740 ONLINE REALM EXTENSION FOR REALM (&00) SUSPENDED
