Third Workshop on Grid Provisioning and Patch Automation

I just conducted a successful third workshop in the Oracle Office at Singapore
on Grid Provisioning and Patch Automation. There were a lot of attendees.
Many who could not attend are asking for repeat seminars.

In the workshop, I introduced the clients to sophisticated Oracle Grid
technology, including RAC, Weblogic server clusters, the Coherence
in-memory data grid, ASM, Oracle Enterprise Linux and Oracle VM.
I interested a lot of attendees in Oracle VM pools with Enterprise Linux
as a future platform for the Grid. I explained the various Enterprise
Manager Packs, especially the Configuration Management Pack and
the Provisioning and Patch Automation Pack.

Using an Amazon installation of Oracle Enterprise Manager
Grid Control Release 5 with the Provisioning and Patch
Automation pack - thanks to one of my friends who loaned me
this Amazon installation - I was able to successfully demonstrate
patching of twelve 10g databases with 5 patches, showing the
power of Grid Automation. The clients were suitably impressed
by the technology capabilities of Grid Control. At the same time
I told them about Oracle’s support of the Cloud.

I also successfully demonstrated a RAC Rolling Patch upgrade
of a two node RAC cluster, again using the Provisioning and
Patch Automation Pack on Oracle demonstration servers.

The DBA attendees asked for:

Ability to backup the db before the patch is applied – this feature is coming
Ability to rollback patches using Grid Control – this feature is coming
Ability to use PBRUN etc for security – which is already there
Ability to do offline download of patches – already there
Ability to keep a log of all changes done via the Grid Control console
Ability to do in Grid Control 10g what can be done in Database Control 11g eg. REPLAY

I have given this feedback to Oracle development.

Future workshops can be seen on:

Interesting questions on Grid Control Patching Automation

In a recent Grid Control Webinar, I heard some interesting questions
by clients that were answered by the Grid Control patching automation
expert in Oracle, Hari, who also writes on this EM Blog. The configuration
question was answered by another Grid expert, Shahid.

I am sharing these answers with you.

Question: Can rollback of patches be done using Grid Control?

Answer: As a part of the procedure, there are validate steps if the patch is
rightly applied or not. Rollback is not available Out-of-box for now, but
you could insert the step into the framework using the metalink note
info - :577557.1

Question: May I know that how frequently Grid Control gathers
configuration changes?

Answer: It is upto you. The interval is configurable. e.g. in the compliance
scenario you would want to gather changes at real time while for standard
application configuration it may be done once or twice a day.

Question: How do I get the details on how to use sudo etc. for patching?

Answer: See the Administrator's guide for provisioning and patching.

Some more feedback on the article:

Another DBA wrote: "Porus, you are the man ... would love to go through your articles. Digging my heels back in Oracle after a while and I intend to go through your articles while in the process. Great Stuff. Great Work."

Another Team leader said:

"I went through some of your papers and they are really amazing I must say. I like the article on Grid Control Architecture and RMAN very much, as we often get this questions from the customers but do not know where to look for. This really gives a very good insight."

Thanks guys for your appreciation of the articles. I wrote them specifically to convince customers that the time is right to use Grid Control. I am happy that you and other readers like them.
