Implementing SQL Plan Management on Oracle Database 11.2.0.2

edited Dec 18, 2013 9:11PM in SQL Performance (MOSC) 6 commentsAnswered
Environment:

Oracle Linux 5 update 10 (UEK)

Oracle GI 11.2.0.2.0 (Oracle ASM 11.2.0.2)

Oracle Database 11.2.0.2.0 Enterprise Edition with RAC option (3 nodes)

No PSU applied/CPU July 2013 applied to RDBMS

Database servicing Siebel CRM 8.1.1.1 Application that uses bind peeking.

Siebel CRM soon to be version 8.1.1.11

There are a few bugs for SQL Plan Management (SPM) on 11.2.0.2 (see below). The slowness and non-peeked binds issues seem very problematic. I've seen a few bloggers recommend to not use SPM unless your at Oracle Database 12c. Several of the bugs seemed to be fixed in 11.2.0.3 but we don't have any plans to move to 11.2.0.3 since we'll most likely be at 12.1.0.x in 7 months.

Howdy, Stranger!
