ORA-24084

Error: ORA-24084: DBLINK name in address field of agent string is not unique within the first 24 bytes"

Causa: Advanced Queuing requires that the agent's DBLINK name should be unique within the first 24 bytes (for 8.0 compatible queue tables)

Acción: Specify a DBLINK name that is unique within the first 24 bytes or migrate to 8.1 compatible queue tables where this restriction is not there.
