Applies to:

Information in this document applies to any platform.

Purpose

The purpose of this note is to publish some recommended fixes in hopes of avoiding problems associated with failure to reproduce desired plans when using SQL Plan Management baselines captured from 12.1.0.1.x.

Scope

This notes contains a list of patches to apply to a 12.1.0.1 environment prior to capturing plans for use with SQL Plan Management.  This can avoid known plan reproduction problems that may prevent SPM in the post-upgrade environment from correctly reproducing the pre-upgrade 12.1.0.1 plans.  Note that unlike other notes in this series, this note is concerned with avoiding reproduction problems post-upgrade, not with avoiding plan reproduction and performance issues in 12.1.0.1.

For best effect, SPM patches for the post-upgrade environment must also be applied.  See the following for patches for other Oracle releases:

<Document 1948958.1> Things to Consider for 11.2.0.3 to Avoid Problems with SQL Plan Management (SPM)
<Document 2034706.1> Things to Consider for 11.2.0.4 to Avoid Problems with SQL Plan Management (SPM)
<Document 2035898.1> Things to Consider for 12.1.0.2 to Avoid Problems with SQL Plan Management (SPM)

If you do not find a patch for your specific version and OS, please open a Service Request with details on the patch needed. Please include a list of patches already applied (opatch lsinventory -detail) as well as any other patches you intend to apply.
