Oracle Solution for Error ora-24057

ORA-24057: cannot define subscriber with rule for queue string

What triggered the Error:

An ADD_SUBSCRIBER or ALTER_SUBSCRIBER procedure with a rule was issued on a queue for which rule based subscribers are not supported. Rule based subscribers currently are supported only for NORMAL (persistent) multi-consumer queues created using an Oracle release 8.1.0 or higher compatible queue table.

What should we do to fix it:

eate a NORMAL multi-consumer queue in an Oracle release 8.1.0 or higher compatible queue table, and retry the call. Or, if the queue is a normal (persistent) multi-consumer queue, convert the queue table to Oracle 8.1.0 or higher compatibility and retry.
