Updates To HS_FDS_CLASS_DATE View Causing HS Message To Agent Waits

(Doc ID 1536085.1)

Last updated on MARCH 11, 2013

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.1 and later
Information in this document applies to any platform.

Symptoms

Using a gateway to a foreign database could cause locks on HS_FDS_CLASS_DATE when several concurrent sessions are trying to fetch data from the foreign database at the same time.  Looking at a systemstate dump it shows that two (or more) processes are doing updates to this view which is resulting in HS message to agent waits
