Are you using Oracle XA by any chance? It also requires a large pool. -Mark -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]On Behalf Of Terry Sutton Sent: Tuesday, May 18, 2004 3:54 PM To: oracle-l@xxxxxxxxxxxxx Subject: ora-4031 & large_pool One of our clients is getting the following error occasionally on a = 9.2.0.3 DB: ORA-04031: unable to allocate 8704 bytes of shared memory ("large = pool","unknown object","hash-join subh","kllcqas:kllsltba") The large pool is set at 16M, which isn't high, but they shouldn't be = using the large pool at all. The don't use MTS, they don't use parallel = query or have parallel_automatic_tuning set to true, and they don't use = RMAN. AFAIK, those are the only things which use the large pool. Any ideas? --Terry ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html ----------------------------------------------------------------- ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
