ORA-24084: DBLINK name in address field of agent string is not unique within the first 24 bytes
Cause: Advanced Queuing requires that the agent's dblink name should be unique within the first 24 bytes (for 8.0 compatible queuetables)
Action: Specify a dblink name that is unique within the first 24 bytes or migrate to 8.1 compatible queuetables where this restriction is not there
