| ERROR | cannot define subscriber with rule for queue string |
| CAUSE | 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. |
| ACTION | Create 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. |
