Veritas ODM library no longer used after RDBMS patchset installation (Doc ID 741015.1)

Last updated on JULY 23, 2010

Applies to:

Oracle Server - Enterprise Edition - Version: 10.2.0.2 to 11.1.0.7 - Release: 10.2 to 11.1
Information in this document applies to any platform.
Database installations using Veritas Storage Foundation for Oracle / Oracle RAC (SFRAC)
and making use of the Veritas ODM (Oracle Disk Manager) library

Symptoms

The Veritas shared library used by Oracle Disk Manager could be lost upon RDBMS patchset
install such as patchset versions 10.2.0.2, 10.2.0.3, 10.2.0.4 or 11.1.0.7.
If this problem is not identified then poor IO performance or a change in IO profile of the
database can result such as cached IO being done to a Veritas filesystem rather than the expected
direct IO as was the case before applying the patchset.

Changes

Applying one of the currently available RDBMS patchsets:

10.2.0.2
10.2.0.3
10.2.0.4
11.1.0.7

on platforms AIX, Linux, HP-UX, Solaris.

Further RDBMS patchset versions which are not yet released as this Note is written can cause the same problem.
