Standby db rolling upgrade for EM Grid?

hi,
We are planning on upgrading the repository database to 11gr1 and since we solely use OEM Grid Control to monitor hundreds of database and application services, we want to minimize the Grid control server downtime.
Is standby db rolling upgrade supported for Grid Control? If not, are there any other alternatives we could implement to provide continual database
monitoring via EM Grid while performing the repository upgrade?
Thanks.

You won't be able to upgrade the database with zero downtime. At some point in the upgrade process, a script will need to be run which will upgrade the Data Dictionary. That script requires the database to be opened in UPGRADE mode, which means downtime.
If you want near-zero downtime, then employing a transient logical standby is a solution. Even this will have some downtime as things are switched over and then switched back.
Cheers,
Brian

Rolling upgrade

Hi all,
How to know if my Oracle home is shared to install the patcher 10.2.0.3 to 10.2.0.4 in rolling upgrade for Oracle Clusterware?
Which refers to the shared homes, only CRS Home or Oracle Home and CRS Home?
I have 3 nodes on RAC.
SO: Solaris Operating System (SPARC 64-Bit)
RDBMS: Oracle 10g R2
Amin

A shared Oracle home is one where a single Oracle Home is accessed via shared storage from multiple nodes. Contrast this with the case needed for rolling upgrade, where there would be a separate Oracle Home installed on each node in the RAC.
The CRS_HOME and ORACLE_HOME should be different in any event (they can be under the same Oracle Base).
Does that help?

Rolling Upgrade of Oracle 10gR2 RAC with Physical Standby (DG)

Hi DBAs,
I want to do a rolling upgrade of Oracle 10.2.0.3 (2 node RAC+ASM) with Physical Standy Dataguard to Oracle 10.2.0.4 also applying CPU (April2009).
Please suggest the best way to perform this upgrade and patching with no downtime.
Thanks
-Samar-

Unfortunately rolling upgrade is only possible with a logical standby in place:

That doesn't help you at this time, but 11g has a way to do it with a physical standby. Even here you need an intermediate logical standby:

Rolling upgrade in MAA database with 2 node RAC on each site

All,
I have 2 node rac on SITE A, and it has Physical Standby database on SITE B it also 2 node RAC. Currently it is on 10.2.0.4 on AIX systems. We have mission crictical application runing and we can't aford the downtime of 5 to 6 hr to upgrade our CRS,ASM,DB oracle homes to 11G or even 10.2.0.5. I read rolling upgrade document on metalink and also documnet as well, and come up with following sequence.
SITE A==Primary Site, SITE B == Standby database
1) Shutdown DB on SITE B
2) Take the OS Level Backup of Binaries only on SITE B (Both node), I think this is just a Precautionary Measure
3) Start the DB on SITE B Still Physical Standby database let it synch with primary Site SITE A
4) Convert SITE B to Logical standby database
5) let it run for some time and be the two site SYNCH
6) now stop archivelog shipping to STANDBY SITE SITE B
7) Shutdown SITE B and apply the patch/upgrade binaries (CRS/ASM/DB)
8) Start and upgrade the DB on SITE B
9) Start the logical standby apply (SQL APPLY) and let it catch up with SITE A
10) Now Switchover to logical standby database on SITE B and ask application to connect to SITE B
11) Make sure the archivelogs are moving from SITE B to SITE A and SQL Apply is runing.
12) Now Stop archive log flow from SITE B to SITE A
13) Stop the database/ASM/CRS on SITE A
14) upgrade the SITE A binaries (CRS/ASM/DB)
15) Start and upgrade the DB on SITE A
16) Start the logical standby apply (SQL APPLY) and let it catch up with SITE B
17) Now Switchover Back to SITE A and let the application connect to SITE A
At this point by SITE B is a Logical Standby database
I think these summaries the steps involved in rolling upgrade, but I can't understand how I can go back to my MAA with physical standby database mode?
Does anyone has done this? Can anyone give me some tips or comments on my steps??
Help me if you can... thanks in advance.

Hi,
Is it you want to know the OS/Kernel side setting? You must comply with the following kernel requirements to install the clusterware.

Database rolling upgrade cpu patch with minimal service outage

Oracle 11gR2 Primary Instance
Oracle 11gR2 Active Physical Standby
Requirement of applying CPU and CVE patches with minimal downtime. I believe that I've been able to apply CPU patch to Active Standby after deferring redo transport and applying patch to active physical standby first and then performing a manual switchover to have the standby become the primary and former-primary become the standby and they apply CPU Patch there and then perform another role transition to its original role.
Appreciate your experience with primary and active physical standby rolling upgrades/patches. Thanks

Hello;
I believe you are over thinking this. All you have to do on the Standby is install the patch. No switchover, no SQL. No nothing.
The SQL will move from the Primary to the Standby.
Check the readme for the patch closely or post the patch number if you want to confirm.
OR
How do you apply a Patchset,PSU or CPU in a Data Guard Physical Standby configuration [ID 278641.1]
( If it helps I had the same thoughts after my first Data Guard setup !! )
If you are trying to avoid downtime entirely the switchover will take about as long as the patch.
If you have RAC this is interesting :

Oracle physru rolling upgrade problem

Hi, I'm having a problem with the Oracle Physru script provided from MOS note # 949322 I was hoping I could get some help with.
My system contains of two Oracle 11.1.0.7.0, one primary and one physical standby.
The hosts are two Oracle Solaris 10 Sparc x64 machines.
My goal is to update from 11.1.0.7.0 to 11.1.0.7.8 using the script that is provided, however I'm bumping into problems at the step where the script is checking the Apply lag on the logical standby (function "get_apply_lag"). The lag seems to increase, and to be that indicates a problem with the redo apply process. However, when I query the DBA_LOGSTDBY_EVENTS View i get the following:

Rolling upgrade from 11.2.0.2 to 11.2.0.3

Windows 2008. 2 node RAC
I attempted a rolling upgrade from 11.2.0.2 to 11.2.0.3 in a dev environment in prep to do my prod. I hit all kinds of issues and when googling I found there was a known issue with rolling upgrades between these versions and there was a patch I was meant to have applied before starting the rolling upgrade. I rolled back to 11.2.0.2 but for the life of me, I cant find reference to that patch now.
anyone know what it is?
/still looking/

Hello,
Please refer below document
Things to Consider Before Upgrading to 11.2.0.3 Grid Infrastructure/ASM (Doc ID 1363369.1)
You can check the section related to 11.2.0.2.
It is better to check complete document carefully before attempting the upgrade.

How to Upgrade to Oracle Grid Infrastructure 11g Release 2

HI
I am experiencing problems to get documentation that is not conflicting. Anyone out there that upgraded from 11.1 to 11.2
Our environment:
4 cluster nodes - 3 ORACLE_HOMES (CRS_HOME, ASM_HOME, DB_HOME).
The new Grid infrastructure creates one home for CRS and ASM.
My problem is that I am trying to do a out-of-place upgrade - using the rolling upgrade method. According to the upgrade manual it is possible.
But I get stuck on the second screen of the Installer, detecting ASM and advises me to shutdown all instances and ASM on node1. Did that, does not work, I am getting the same message INS-40413.
Anyone out there that has got some procedures, or maybe experience about this. I am trying to get advise from Oracle since early November, but did not get any further.
Irene

Execute the below command at OS level and verify from which home is the crsctl utility is being called
which crsctl
Ensure that the above command is being called from the correct home
If the path from which crsctl utility is being called is the correct one, then perform starce on the crsctl command and verify the starce output to check if it truly is using 10g binaries or not
If not, then try unlocking and locking the GI binaries using "rootcrs.pl -unlock" (to unlock) and "rootcrs.pl -patch" (to lock the binaries), once done verify if you are still getting the same issue or not

SQL Apply Rolling Upgrade

Hi,
I would like to upgrade our Oracle database from release 9i to oracle 10g.
Anybody have used "SQL Apply Rolling Upgrade" with a SAP application to upgrade the database ?
Thank's in advanced
Francesc

Hi Cristian,
well you can do / try that, but it is not supported in a SAP environment.
SQL Apply means Logical Standby database and this is explicitly not supported in a SAP environment - for more details please check SAPnote #105047 (sub point 14 - Oracle Data Guard).
However from a technical point of view it is possible as none of these restrictions usually apply a SAP environment ( Data Type and DDL Support on a Logical Standby Database ).

Is it possible to delay a rolling upgrade after a single domain is updated?

Hello,
I am working on new Azure services for my group. For various reasons, we have decided that a Staging / VIP-Swap deployment is not useful for our group and will be going with a rolling upgrade. What I am interested in, is knowing if there is a way to
"pause" a rolling upgrade after the first update domain until it is released to complete. Or, for a set time ( 30 minutes, etc ), to allow us the opportunity to essentially have a A-B deployment of our webrole, to observe behavior while receiving
production traffic before the release has completely deployed.
Thanks for your help
Jeff

hello Jeff,
Currently, base on my experience, delay a rolling upgrade or "pause" a rolling upgrade after the first update domain until it is released to complete, it may be difficult. I suggest you could can submit a feature suggestion on
http://www.mygreatwindowsazureidea.com/forums/34192-windows-azure-feature-voting. I suggest you could get more detail about upgrade domain and fault domain (http://blog.toddysm.com/2010/04/upgrade-domains-and-fault-domains-in-windows-azure.html).

Rolling upgrade from 11.1.0.6 to 11.1.0.7

Hello -
I am testing the "rolling upgrade" from 11.1.0.6. to 11.1.0.7. I have a two node cluster on Linux. Is there a way to upgrade either the ASM software or the dbms software without causing downtime to the entire cluster? I can upgrade the clusterware in a true rolling fashion. However, when I attempt to upgrade the ASM location, it ends up taking down the other node. Same for the rdbms software - The other instance ends up going down when I start the patching on one instance - from the remove operations being performed. Has anyone successfully patched an entire stack (without downtime)?
Thanks in advance for any insights!

Yes, I am following those instructions. The ASM instructions caused the other node to be inaccessible. But, when I did the rdbms upgrade, then node B was also inaccessible during that time. I will go through more iterations of this testing, but so far, I have not been able to develop a proof of concept for a true rolling upgrade from 11.1.0.6 to 11.1.0.7. If anyone has been able to do this, please let me know the procedures that were followed.
Thanks,
Mike

Rolling upgrade of WLC 4402 controllers and APs

In need to upgrade the software on two WLC 4402 controller in a hospital. Both WLCs have the same config and one is primary (has all APs connected) and the other backup (no APs connected.) The APs are placed so there is still coverage if one goes down in an area. My question - is it possible to do a rolling upgrade to have no downtime for the wireless clients? My plan would be to upgrade the backup WLC then selectively move APs to it. If I swap the primary and secondary controllers in the high availability tab on each AP, do I need to do a reset (General - Hardware Reset) or will it automatically reboot and connect to the upgraded backup controller? When I'm done, I'd upgrade the primary controller and now call that backup. Does this make sense?

I've done this same sort of thing on a slightly larger scale about 5 times now at the hospital I work at. Quick answer is "Yes, it is possible to do a rolling upgrade and have no downtime for wireless clients."
I've got 5 WLC's, and I use the high availability tab to move all the AP's off one, upgrade it, and move all the AP's from the next WLC over to it, upgrade that one, etc.
The thing you need to be careful of is your timing and your choice of APs to move.
It generally takes about a minute to move an AP between WLCs running the same version. But if there's a version change that makes the AP upgrade, you're looking at about 6 minutes.
I do them one at a time, and when they show up in the WLC as being up, running and happy for 1 minute, I do the next one. And so on. Takes me about 3 days to go through all 5 WLCs and 375 APs. Not once have I had a user notice the move.
Also, in order to test, after I do the first upgrade, I move just one area's APs into that WLC for a day and then test the various flavors of gear we have (phones, infusion pumps, laptops, etc.) to confirm that the new version doesn't have any trouble. Sometimes it does and I work with TAC to get things resolved before I do the whole hospital.

Java.io.StreamCorruptedException after rolling upgrade

Hi,
After removing a first class citizen Class file A in Version2 and performing a rolling upgrade from Version1 to Version2 of our software we find an entry for Class A in replicated cache of Version2. Once we try to read / remove / or overwrite it with null we get a "java.io.StreamCorruptedException".
Is there a way to get rid of these kind of entries in the cache after rolling upgrade is performed or even prevent Class A to be added into the cache during de-serialization?
Thanks

I'm not quite sure what you mean yet. Are you talking about the server code or the client code? And, can you be a little more specific on where the problem is? I'm sorry, it's just that I've spent quite a while on the code and I haven't found the problem yet. Thanks again.

OS upgradation For RAC

Hi guys...How is everything.....
I have Node RAC on Windows2003R2 Itaniam. I Need to know is there any procedure for OS upgradation for RAC..I mean shall I down the Cluster & Database when OS up gradation..

Hi JIC,
Please be more specific. Do you plan upgrade OS for Win2008? Or did you means service packs and patches through windows update?
In general, if your OS is certified by Oracle to run RAC if you are using service pack 1,2,3 doesn't matter, they are certified too.
"The Oracle Clusterware and Oracle Real Application Clusters both support rolling upgrades of the OS software when the version of the Oracle Database is certified on both releases of the OS (and the OS is the same, no Linux and Windows or AIX and Solaris, or 32 and 64 bit etc.). This can apply a patch to the operating system, a patchset (such as EL4u4 to EL4u6) or a release (EL4 to EL5). Stay within a 24 hours of upgrade window and fully test this path as it's not possible for Oracle to test all these different paths and combinations."
This rule is valid to Unix/Linux and windows Systems.
You can check it on My Oracle Support note ID 220970.1
