Distributed Query Returns Different Results on Consecutive Runs when no Changes Exist in the Base Tables.

(Doc ID 561471.1)

Last updated on SEPTEMBER 15, 2008

Applies to:

Oracle Server - Enterprise Edition - Version: 8.1.5.0 to 11.01
This problem can occur on any platform.

Symptoms

Distributed Queries can sometimes return different results in consecutive runs, even when the base tables have not changed during the query executions.
The problem can appear in normal queries, when using views, materialized views refresh or any other operations using distributed queries. They are all the result of the same cause.
This can appear as a bug at first look, but is actually the expected behavior.
