Advanced Queueing objects left invalid after executing DBMS_AQADM.PURGE_QUEUE_TABLE with a null condition or performing a shrink (Doc ID 1523068.1)

Last updated on AUGUST 10, 2015

Applies to:

Oracle Database - Enterprise Edition - Version 10.2.0.5 to 11.2.0.4 [Release 10.2 to 11.2]
Information in this document applies to any platform.

Symptoms

Objects associated with a multi-consumer queue table are left invalidated when dbms_aqadm.purge_queue_table is executed with a null condition which effectively truncates the queue table and the relevant associated IOTS/tables.

These invalid objects can be the evaluation context, rulesets or queues themselves.

However, the queue can still be successfully used for Advanced Queueing (AQ) enqueue/dequeue operations after the purge but not all the objects automatically revalidate.

The same issue can be observed when performing an 

alter table <queue_table> shrink;

operation.
