PSU1 and PSU2: Datapatch Issues coverd in MOS Note

You may have read a posting disrecommending PSU1 and PSU2 for Oracle Multitenant especially in RAC/GI environments earlier this week. Actually following a lot of internal discsussions I will post some advice and clarification later this week.

Now I have an useful update:
Datapatch Issues are covered within a separate MOS Note making it easier to keep track and find workarounds for known issues.
Please see MOS Note:1609718.1 Datapatch Known Issues

MS Windows Bundle Patches - a VERY different story

I like Upgrade Workshops for a very different reason:
Hopefully people feed back with questions and information I wasn't aware off before. So for myself these workshops are also a learning experience. And thanks to a customer in Singapore (Thanks a lot, Hanh!!) I learned something about Oracle's Bundle Patches for MS Windows.

Customer asked about a specific issue when using RMAN Duplicate command in 12c failing with a nice ORA-600 [KSRPCSEXEC_1]. This got logged a while ago as bug16883554 - and it will be fixed in database patch set 12.1.0.2. But this customer asked for an earlier delivery.

So after a quick check of the SR and the bug it was clear that this patch will be also included for the MS Windows platform into the Bundle Patch 12.1.0.1.4 on Win.
Well, my first thought: Ouch! That will be the July 2014 PSU.

But in fact it isn't meant here. So I learned that on Windows patching runs on a different schedule and notation.

October 2013 PSUs and CPUs - News for 12c

Last night CET the most recent Patch Set Updates (PSU) and Critical Patch Updates (CPU aka SPU) got published on MOS. And there's a significant and remarkable change for Oracle Database 12c onwards. MOS Note: 1571391.1 - Patch Set Update and Critical Patch Update October 2013 Availability Document says:

2.1 Database Security Patching from 12.1.0.1 Onwards

Starting with Oracle Database version 12.1.0.1, Oracle only provides Patch Set Updates (PSU) to meet the Critical Patch Update (CPU) program requirements for security patching. Security Patch Updates (SPU) will no longer be available. Oracle has moved to this simplified model due to popular demand. The PSU is Oracle's preferred proactive patching mechanism since 2009.

For more information, see My Oracle Support Note 1581950.1, Database Security Patching from 12.1.0.1 onwards.

That's a real change. It's not harmful at all as our recommendation for years now is to apply PSUs as they contain not only the security patches but also the important fixes for critical issues. And apply them asap - the day we publish the Security Patch Advisory with some details is the day when external security experts go public as well with their findings.

MOS Note: 756671.1 - Oracle Recommended Patches -- Oracle Database will guide you to the databases patches for your platform. If you miss the PSU for Oracle Database 10.2.0.5 (the Pre-Release Announcement stated that there will be a PSU for 10.2.0.5) my personal understanding is: as Oracle 10.2.0.5 went out of Extended Support in July 2013 there won't be any October PSU released anymore.

And I'll apply the new 12.1.0.1 Oct13 PSU now to my Oracle Database 12c Multitenant environment as well :-)

Why is every patchset now a full release?

This question got posted by Naveen in the previous entry today - and I found it worth it to create a new blog entry as this question gets raised in nearly every 2nd workshop as well - so others might be interested as well.

Mike,

A question has been bothering me for a while and I thought I'll throw it out there. I didn't raise a support ticket, I knew what the response is going to be.

So here is the question. I have an 11g ORACLE HOME that was built as 11.2.0.1. Now if I want to upgrade to 11.2.0.2 or 11.2.0.3, I guess there is no easy way to upgrade the existing ORACLE HOME. Why didn't Oracle give the option to just apply a patch (opatch) and upgrade to 11.2.0.2 (or .3). For a customer to create a new ORACLE HOME is just a lot of work and breaks a lot of things. We have to copy over so many configs from the old home to the new home.

I'm sure there is a good reason, I'm just trying to understand what they are.

Thanks
Naveen

Naveen, thanks for your question. And the answer has many aspects.

Install into your existing ORACLE Home

First of all you can still install the new patch set (which is now a full release since Oracle 11.2.0.2) into your existing $ORACLE_HOME. But you'll have to detach your current home from the OUI's inventory first. Please see slide 41 of the Upgrade and Migration workshop deck. Please backup the contents of $ORACLE_HOME/dbs and $ORACLE_HOME/network/admin first as you'll have to copy them back later.

$ ./runInstaller -detachHome ORACLE_HOME=/u01/orahomes/11.2.0

Starting Oracle Universal Installer...

Checking swap space: must be greater than 500 MB. Actual 10047 MB Passed

The inventory pointer is located at /etc/oraInst.loc

The inventory is located at /u01/orabase

'DetachHome' was successful.

Once you've done that you'll install into your existing (old) directory.  And finally you'll copy back your dbs and network/admin files.

Why customers might use this procedure?

There are basically two reason why a customer chooses this strategy:
(a) Home naming conventions not allowing an Oracle 11.2.0.2 home and another Oracle 11.2.0.3 home
(b) Space issues
Both are valid reasons and therefore you can stay with the old strategy.

Why did we change from patchsets to full release patchsets?

Simple reason: Customers did ask us for a looooong time why we are delivering 3GB large patchsets instead of full releases. So we'd follow this wish. And second it will decrease the overall downtime when you'd install into your new Oracle Home. If you apply patchset software to your existing Oracle Home every Oracle process serviced by that home must be shut down as well - obviously including the database(s). And furthermore if something fails you'll have to restore your OUI's inventory plus all home contents - or reinstall your previous Oracle software.

Besides that we recommend to patch this home first with important one-offs (see links in MOS Note 161818.1) and the latest PSU or CPU. If you'd do that to your already emptied old home it will simply increase again your overall downtime.

And this is the reason why we recommend:
Always install into a new Oracle home beginning with Oracle Database 11.2 - don't erase your old home to reuse it unless there's no significant need for that procedure.

11.2.0.2 Bundled Patch 3 for Linux x86-64bit released


NOTE ADDED ON 25-MAY-2011


Please be aware that this entry has been published a long while ago. As of today (end of May 2011) Exadata BP10 (and not BP3) is the most recent Bundle Patch. And me and some colleagues have learned in the past months that applying Exadata BPs to a non-Exadata environment might cause some trouble once you request an one-off/interim patch on top of an Exadata BP.


Officially this Bundle Patch for Oracle Database 11.2.0.2 is titled "Exadata Database recommended patch" and got released yesterday. But I would recommend this one to all customers using 11.2.0.2 Grid Infrastructure, RAC and ASM.

pflaster.jpg

Reason?
Please see the readme.

 

 


  • Total of 42 bug fixes are included in this bundle

  • 40 Database fixes( 4 are diskmon, 12 are ASM)

  • 2 Database fixes from PSU/CPU Jan2011( 17 of the content has already been included in the previous release,BP2)

  • The patch contains Database, Diskmon and CRS patches packaged as a single patch.

  • This bundle is both DataGuard Rolling and RAC Rolling Installable.

  • This patch will be installed using "Opatch Auto" feature of Opatch.

 

Information on the bugs included, install requirements and known issues are documented in the README. Tracking bug is 10387939.
To download this Bundle Patch login to support.oracle.com and proceed to Patches and Updates. Fill in the bug number 10387939 and search to access the download screen.

Note 1:
Make sure you'll use the latest version of opatch (Patch 6880880) if you'd like to use the new auto functionality. Otherwise you'll see this error:
Error :
Undefined subroutine &main::unlockCRSHomeforpatch called at /u01/app/11.2.0/grid/OPatch/crs/patch112.pl line 1529


Note 2:
Per discussion with Oracle Support I would like to emphasize that applying this BP3 to RAC systems is my personal recommendation. Oracle Support will still recommend applying the PSU+GI Bundle Patch instead of the Exadata Bundle Patch. But nevertheless applying the Exadata Bundle Patch is supported as well.
