Parameters

condition

Specifies the purge condition to use when purging the queue table. The purge condition must be in the format of a SQL WHERE clause, and it is case-sensitive. The condition is based on the columns of aq$queue_table view.

block

If block is true, then an exclusive lock on all the queues in the queue table is held while purging the queue table. This will cause concurrent enqueuers and dequeuers to block while the queue table is purged. The purge call always succeeds if block is true. This will not block enqueuers and dequeuers, but it can cause the purge to fail with an error during high concurrency times.

deliveryMode

This parameter is used to specify delivery mode of messages are to be purged. You cannot implement arbitrary purge conditions if buffered messages have to be purged. (Used in Oracle Server 10.2 only.)

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
