Last updated on MAY 15, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 11.1.0.7 and later
Information in this document applies to any platform.

Symptoms


=== ODM Issue Clarification ===

The write performance to a compressed lob degrades as the size of the lob data
being inserted increases.

This is only observed when using an XA connection.

When a non XA connection is used there is no write performance degradation observed.

Changes

XA connection used with lob stored using storage option : SECUREFILE and COMPRESS.
