Applies to:

Oracle Database - Enterprise Edition - Version 8.1.7.0 to 11.2.0.2 [Release 8.1.7 to 11.2]

Information in this document applies to any platform.

Symptoms

Messages have been enqueued and dequeued messages successfully from a queue within the same session.

The no_wait option has been specifie as a dequeue option.

Subsequent dequeues of messages which are enqueued from the same session return the error:

ORA-25228 "timeout or end-of-fetch during message dequeue from <schema>.<queue>"

The following query reveals that messages are in the ready state for the queue:

select distinct msg_state from <schema>.aq$<queue_table> where queue = '<queue>';

where <queue_table> is the queue table associated with the <queue>  (dba_queues).

Logging  into another session as the same user and the dequeue succeeds without error.

The same error is reported whether you use a multiple or single-consumer queue.
