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 ).

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 Upgrades in Rac

Hi All,
can you please explain abt rolling upgrades in rac env
suppose i am having rac setup on 10.2.0.1 if i want to apply patch set 10.2.0.4 is it required downtime
As per the readme of 10.2.0.4
1)Stop every thing on node 1 and apply patch set
2)stop every thing on node 2 and apply patch set
3)stop the database and run the catupgrd.sql script.
My question is for running catupgrd script i have to bring down the db so what the meaning of rolling upgrade??
And in this type of sece which type of upgrade is best one rolling or non-rolling.
KK

Hi HTH
Thank you for clearing my doubts regarding Rolling upgrades and i have gone though the link and i have noticed the following steps
For Standalone system
1) Install Oracle 10g to a separate Oracle Home on the same server
2) Create a 10g database with only the base tablespaces: SYSTEM, SYSAUX, UNDO, and TEMP
3) On the 9i database, put all your tablespaces into read only mode (write downtime begins)
4) Perform a transportable tablespace export of all non-system tablespaces (as a sysdba user)
5) Shut down the 9i database (true downtime begins)
6) Start up the 10g database
7) Perform a transportable tablespace import into the 10g database (end true downtime)
8) Make all your tablespaces read/write (end write downtime)
The above steps is going to work only for 9i to 10g or can we use it to any version to version.
BY using TTS is it suggestable method to do the upgrade??

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:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/upgrades.htm#CHDBJAGG
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 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.

Vijay

Logical standby stuck at initializing SQL apply only coordinator process up

Hi
OS: solaris 5.10
Hardware: sun sparc
Oracle database: 11.2.0.1.0
Primary database name: asadmin
Standby database name: test
I had been trying to convert a physical standby to logical standby database. Both the primary and standby reside on the same machine.
The physical standby was created with a hot backup of primary.
I had been following document id 278371.1 to convert the physical to logical standby and used the following steps:
Relevant init parameters on primary:
*.db_name='asadmin'
*.db_unique_name='asadmin'
*.log_archive_config='dg_config=(asadmin,test)'
*.log_archive_dest_1='location=/u01/asadmin/archive valid_for=(all_logfiles,all_roles) db_unique_name=asadmin'
*.log_archive_dest_2='SERVICE=test async valid_for=(online_logfiles,primary_role) db_unique_name=test'
*.log_archive_dest_state_1='enable'
*.log_archive_dest_state_2='enable'
*.fal_client='asadmin'
*.fal_server='test'
*.remote_login_passwordfile='EXCLUSIVE'
Relevant init parameters on standby database:
*.db_name='test' -- Was asadmin before I renamed the DB during conversion to logical standby
*.db_unique_name='test'
*.log_archive_dest_1='location=/u01/test/archive valid_for=(all_logfiles,all_roles) db_unique_name=test'
*.log_archive_dest_2='service=asadmin async valid_for=(online_logfiles,primary_role) db_unique_name=asadmin'
*.log_archive_dest_state_1=enable
*.log_archive_dest_state_2=defer
*.remote_login_passwordfile='EXCLUSIVE'*.fal_server=test
*.fal_client=asadmin
Steps on primary:
1) alter system set log_archive_dest_state_2=defer;
2) shutdown immediate;
3) Made sure that the physical standby has applied all of the redo sent to it following the shutdown.
4) startup mount;
5) ALTER DATABASE BACKUP CONTROLFILE to '/home/oracle/control01.ctl';
6) ALTER SYSTEM ENABLE RESTRICTED SESSION;
7) ALTER DATABASE OPEN;
8) Verified that the supplemental logging is on.
9) ALTER SYSTEM ARCHIVE LOG CURRENT;
10) Checked for the checkpoint change no. at this point which is 72403818 and is present in archive log file 1_62_775102253.dbf
11) EXECUTE DBMS_LOGSTDBY.BUILD;
12) ALTER SYSTEM ARCHIVE LOG CURRENT;
13) Checked for the archive log containing dictionary build which is 1_64_775102253.dbf
14) ALTER SYSTEM DISABLE RESTRICTED SESSION;
Details of archive logs and related checkpoint change nos:
NAME FIRST_CHANGE# NEXT_CHANGE#
/u01/asadmin/archive/1_61_775102253.dbf 72402901 72403817
/u01/asadmin/archive/1_62_775102253.dbf 72403817 72404069
/u01/asadmin/archive/1_63_775102253.dbf 72404069 72404211
/u01/asadmin/archive/1_64_775102253.dbf 72404211 72405700
Steps on standby:
1) shutdown immediate;
2) Copy the archivelog file 61(was created at primary after apply stopped at standby), 62(contains checkpoint no. 72403818), 63 and 64(contains dictionary build). Copy the backup controlfile from step 5 above to the controlfile location in standby init.
3) startup mount;
4) Rename all datafiles and redo log files (including standby redo log files) to the correct path on standby.
5) alter database recover automatic from '/u01/test/archive' until change 72405700 using backup controlfile; -- This completed error-free
6) alter database guard all; -- this completed error free
7) alter database open resetlogs; -- this completed error free.
8) nid target=sys/oracle12 dbname=test
9) Changed the db_name in init file to new name test.
10) Added a tempfile to temp tablespaces.
11) ALTER DATABASE REGISTER LOGICAL LOGFILE '/u01/test/archive/1_61_775102253.dbf'; -- ORA-16225: Missing LogMiner session name for Streams
12) ALTER DATABASE START LOGICAL STANDBY APPLY INITIAL 72405700; -- This completed error free.
Also enabled the log_archive_dest_state_2 on primary.

I also greped for lsp and lcr processes and found that lsp is up but do not see any lcr.
The logs are getting transported to the archive destination on standby whenever they are archived on primary but are not getting applied to standby.
Also in case the standby is down while a log is generated on primary it is not automatically transported to standby once the standby is up, means gap resolution is also not working.
I see the following in alert log every time I try to restart the log apply, everything seems to be stuck at initialization.

Hello;
I noticed some of your parameters seem to be wrong.
fal_client - This is Obsolete in 11.2
You have db_name='test' on the Standby, it should be 'asadmin'
fal_server=test is set like this on the standby, it should be 'asadmin'
I might consider changing VALID_FOR to this :

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).

Logical Standby SQL Apply Using Incorrect Decode Statement

We are seeing statements erroring out on our logical standby that have been rewritten (presumably by sql apply) with decode statements that don't appear to be correct. For example, here is one of the rewritten statements.
update /*+ streams restrict_all_ref_cons */ "CADPROD"."OMS_SQL_STATEMENT" p
set *"APPLICATION"=decode(:1,'N',"APPLICATION",:2)*,
"STATEMENT"=dbms_reputil2.get_final_lob(:3,"STATEMENT",:4)
where (:5='N' or(1=1 and (:6='N' or(dbms_lob.compare(:7,"STATEMENT")=0)or(:7 is null and "STATEMENT" is null)))) and(:8="APPLICATION")
The problem comes in, we believe, with the attempt to write the value "APPLICATION" to the application column which is only a 10 character field. the value for the :1 bind variable is "N" and the value for :2 is null.
We see the following error on the logical standby:
ORA-00600: internal error code, arguments: [kgh_heap_sizes:ds], [0x01FCDBE60], [], [], [], [], [], []
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [kxtoedu+54] [PC:0x2542308] [ADDR:0xFFFFFFFFFFFFFFFF] [UNABLE_TO_READ] []
ORA-12899: value too large for column "CADPROD"."OMS_SQL_STATEMENT"."APPLICATION" (actual: 19576, maximum: 10)
Is this a configuration issue or is it normal for SQL Apply to convert statements from logminer into decode statements?
We have an Oracle 10.2.0.4 database running on windows 2003 R2 64-bit os. We have 3 physical and 2 logical standby's, no problems on the physical standbys.

Logical standby: SQL Apply too slow

Hi all,
I have a question regarding SQL Apply performance in logical standby. There are two kind of operations that are remarkably slow when applying them on logical standby. These are "truncate table" and "delete from table" operations.
When logical standby pick up one of mentioned statements from logs one of appliers start working whereas rest others are waiting. It looks like standby hang and very slow sql apply is moving on gradually and finally when operation completes standby is behind primary for 4 or 5 or even 8 hours.
What can be done in this regard to speed up sql apply and alleviate this situation?
Best Regards,
Alex

Are you absolutely sure that the truncate is the problem (and deletes). How did you check it?
You can use LogMiner to check what are most of the commands in the log currently applied. I use this:
BEGIN
sys.DBMS_LOGMNR.ADD_LOGFILE( LOGFILENAME => '/home/oracle/arc_43547_1_595785865.arc', OPTIONS => sys.DBMS_LOGMNR.ADDFILE);
END;
BEGIN
sys.DBMS_LOGMNR.START_LOGMNR( OPTIONS => sys.DBMS_LOGMNR.DICT_FROM_ONLINE_CATALOG);
END;
SELECT seg_owner,seg_name,table_name,operation,COUNT(1) FROM V$LOGMNR_CONTENTS
GROUP BY seg_owner,seg_name,table_name,operation
ORDER BY COUNT(1) DESC
BEGIN
sys.DBMS_LOGMNR.END_LOGMNR();
END;
Most of the times in our cases when SQL Apply is slow is because of high activity on particular object. This can be detected by high number of DMLs for that object using LogMiner. If this object is not needed on the logical standby you can skip it and thus SQL Apply will be faster because it will not apply changes for this particular one. If it's needed and this is not a regular rate, then you can skip it temporarily, turn on SQL Apply , after problematic logs are applied, turn off SQL Apply, instantiate the object and unskip it, turn on sql apply again.
Another thing that can drastically slowdown SQL Apply is the size of memory available for SQL Apply(Alert log shows that max is ~4.5GB or something like this, I'm not sure )
You can increase it with something like this:
ALTER DATABASE STOP LOGICAL STANDBY APPLY;
BEGIN
DBMS_LOGSTDBY.APPLY_SET('MAX_SGA', 3000); -- set to 3000 MB
END;
ALTER DATABASE START LOGICAL STANDBY APPLY;
You have to increase it if the following reports:
SELECT NAME, VALUE FROM V$LOGSTDBY_STATS
WHERE NAME LIKE '%page%' OR
NAME LIKE '%uptime%' or name like '%idle%';
that 'bytes paged out' increases if run every few seconds during slow SQL Apply.
I hope that it's something that can be fixed using the above info. If no, please comment and share your investigations.
Thanks

Slow SQL Apply on Logical Standby Database in Oracle10g

Hi,
We are using Oracle 10g Logical Standby database in our production farm but whenever there is bulk data load (5-6 GB data) on the primary database, the logical standby seems to be hung. It takes days to apply the 5-6 GB data on the logical standby.
Can anybody give me some pointers how can I make my SQL Apply fast on the logical standby for bulk data.
Thanks
Amit

Hi there,
I've a similar problem. I did an insert of 700k on a table. It takes me over 1 1/2 hours to see the data. Notice, I increased the "max_sga" to 300m and "max_servers" to 25" and didn't help the performance at all.
My version is 10.2.0.3 with the patch 6081550.

SQL apply is very slow on Logical Standby..!!

Hello all,
We are having Data Guard setup in our environment where we are having Primary, Physical Standby as well as logical standby databases..
DB Version : 10.2.0.1 in all databases (Pri, Phy and Logical)
OS : RHEL4
Only Oracle is running on this Box..
Since last month we are facing problems in Logical Standby database where it seems SQL apply has become very slow..
Archive log files are successfully transferring from Primary but since SQL apply has become slow logical standby is lagging behind primary by two days..
How do i speed up this SQL apply..?? Any ideas and suggestions are most welcome..
I checked TOP command to find out which oracle processes are consuming maximum CPU and i have found ora_p000_oracle, ora_p001_oracle, ora_p002_oracle, ora_p003_oracle, ora_p004_oracle, ora_p005_oracle, etc processes are consuming highest CPU and Load Average has always been above 1..
Any help would be greatly appreciated..
Thanks - HP

Scshutdown fails - "Rolling Upgrade in progress"

Anybody seen this before?
bash$ sudo scshutdown -g 0 -y
scshutdown: Cannot shutdown the cluster. Rolling Upgrade in progress.
bash$
No one has (with intention) started an upgrade on this cluster.. Its SC3.1 U2 on Solaris 8.

While you are saying that no one hast started an upgrade, is it possible that this cluster got recently patched with current Sun Cluster patches?
If so, you might want to check if the follwoing binary exists on your cluster:
/usr/cluster/bin/scversions
If it exists, just call it.
If you see something like:
# scversions
Upgrade commit is NOT needed. All versions match.
then I don't know what your problem is. However, if it says something different, you might want to try:
# scversions -c
and see if the problem went away.
