Active Data Guard & Fusion Middleware Repositories.

with one comment

Last year while working on a POC Rob den Braber noticed the following in Disaster Recovery for Oracle Elastic Cloud with Oracle ExaData Database Machine on page 13:

Currently, Oracle Fusion Middleware does not support configuring Oracle Active Data Guard for the database repositories that are a part of the Fusion Middleware topology. However, Active Data Guard can be configured if your custom applications are designed to leverage the technology.
Today this came up in a discussion with Simon Haslam , and he didn’t hear from this support issue before. So it seems that it is not that well know that Active Data Guard and Oracle Fusion Middleware is not a supported combination.
This makes this blog post a reminder from what is already in documentation (unless someone can comment and tell me that currently in the quote is not so currently anymore).
Hope this helps.
UPDATE:
While reading this brand new SOA HA paper I found this quote today:

The Oracle Active Data Guard Option available with Oracle Database 11g Enterprise Edition enables you to open a physical standby database for read-only access for reporting, for simple or complex queries, or sorting while Redo Apply continues to apply changes from the production database. Oracle Fusion Middleware SOA does not support Oracle Active Data Guard because the SOA components execute and update information regarding SOA composite instances in the database as soon as they are started.

Small things you notice

In the past you always had to remember to start your database services after you (re)started a RAC database. To automate this I used to create a script in $CRS_HOME/racg/usrco.

Just today I noticed that Oracle starts your services automatically when you have GI version 11.2.0.2.0. Can’t say for sure this is also the case on 11.2.0.1.0.

Yet another custom script can be trashed, I start to love default more and more every day 🙂
