Applying patches to physical standby node(Data Guard 10.2.0.3)

Hello,
I have a data guard 10.2.0.3 environment (1 primary and 1 physical standby on a separate node) on solaris 10 and i want to document the procedure in applying patches to this environment.
I saw the article in Metalink Note 278641.1 which describes the procedure in applying a patchset to both nodes. It looks like both nodes need to be down before applying the oracle patchset.
Can we not apply the patches on only the standby while the primary stays up and running? My guess is you can't if the patches are significant i.e. it changes versions of the oracle binaries. But i want to confirm this.
Also, if we are applying solaris patches, i.e. nothing related to Oracle, we should be able to just apply them to the standby while keeping the primary up and running right?
The following has worked so far but i wanted to find some documentation that confirms it's ok.
1. shutdown oracle on standby node.
2. apply solaris patches...
3. restart oracle on standby node and put in managed recovery mode.
Any comments are appreciated.
Thanks.

Hi
Did you get an answer for your question yet? I have the same problem with one of our databases. Would be very nice, if you could tell me.

Error while trying to open physical standby database - (DATA GUARD)

Hi Everyone,
I have problems in opening the database of the physical standby in read- write mode/ read only mode. I have a primary server which is running on 2 node RAC and the standby on a seperate single server being used as DR. I recently got this server and my aim was to isolate the standby server from primary server and perform few test. As it has never been tested even once.

2- I run this comman in rman for recover standby database

hi
I myself have found the solution , when I recover the standby database
it do recovery but at the end of recovery it raise the error(RMAN-06054: media recovery requesting unknown log: thread 1
seq 118 lowscn 1392700) but if I begain redo apply before open the database
and I wait till all redo apply process start and communication between the
standby database and the primary database start, then I can
open the standby database and no error will raise
but if befor restarting redo apply I open the database I'll recieve the
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/u01/app/oracle/oradata/sari/system01.dbf' error

Patching with physical standby document

There is this old document targeting 9i. Is there anything for 11g of a similar nature:

Can a physical standby propagate data to a logical standby?

Here is my situation. I have a RAC database that currently has a physical standby (also RAC cluster) for disaster recovery (DR) and I am about to create an additional logical standby for real-time reporting. My customer is asking if I can also create a logical standby for reporting that resides in the DR environment that would be available in a disaster. My question is can a physical standby propagate data to a logical standby? Is there any special configuration that would be required and what might it be if this is possible?
Thanks.

Hi,
Welcome. Yes it's possible, example in 11.2 :
A cascading standby database can cascade primary database redo to up to 30 cascaded destinations, each of which can be a physical, logical, or snapshot standby database.

How to apply Oracle patch when physical standby database in place

Dear All,
I want to apply Oracle patchset 8 on 10.2.0.5 when physical standby database in place. What are the steps for Primary site and for standby site.
Thanks in advance
Kamran Laeeq

Hi Kamran,
You will not upgrade or patch the standby database by importing offline redologs. On the contrary, there is a procedure to do this. Please note that you will not transitiate the role from standby to primary or startup the database. You will just startup the database by executing "startup mount" and "startup upgrade", during the upgrade. It means that you will not change database role standby to primary and you will be able to continue to the log shipment after the respective upgrade.
But, it is very important that you should stop the log shipment and apply all the offline redologs, before the upgrade. Technically, you can import offline redologs after the upgrade, by changing "compatibility" parameter in oracle, but regarding to my experiences it may cause some problems after you transitiate the role from standby to primary.
In short;
In order to stop log shipment, at the primary site;
alter system set log_archive_dest_state_2=defer;
In order to import all the offline redologs without a delay, at the standby site;
alter database recover managed standby database cancel;
alter database recover managed standby database nodelay disconnect from session;
I hope that I clarified the issue,
Best regards,
Orkun Gedik

How Real Time Apply works while physical standby is open in Read Only mode

Hi,
With Active data guard option, we can open physical standby DB in read only mode, while redo log are being applied. (Real Time Query)
Standby Redo log (SRL) enables Real Time Apply (with "USING CURRENT LOGFILE" clause in recover database command on standby DB)
I am interested to know, how Real Time Query works ?
What is the mechanism with allows us to open physical standby DB in read only mode while redo logs are being applied continuously ?
Regards,
Sujit

Dear user7419391,
That is a new feature in Oracle Database 11g. MRP can use the real time apply in 10g but the concept here is different.
Taken from the following document;
http://www.ascent.co.za/documents/oracle/Oracle%20databse%2011g%20Active-Data-Guard%20datasheet.pdf
*Unique Advantages of Oracle Active Data Guard*
+Active Data Guard is an evolution of Data Guard technology, providing unique+
+performance advantages while leveraging all other enhancements included in Oracle+
+Data Guard 11g. For example, any Data Guard 11g physical standby database can+
+be easily converted to a Snapshot Standby. A Snapshot Standby is open read-write+
+and is ideally suited as a test system, able to process transactions independent of the+
+primary database. A Snapshot Standby maintains protection by continuing to receive+
+data from the production database, archiving it for later use. When tests are+
+complete, a single command discards changes made while open read-write and+
+quickly resynchronizes the standby database with the primary.+
The other link in the previous post is excellent and you really have to read it to understand the active data guard aspects.
Regards.

Appying patches when Physical standby in place.

Kindly suggest steps for patch application /application upgradation. We dont have any replication tool.What is the standard process to sync standby after patch upgradation . Is there any alternative of rsync/rdist utility.
Is it possible that after applying patch in Primary, On Standby we have to apply as it is, with no Database inclusion as the standby database will be in mount state and will not available for making database changes.
How to find which files to be copied manually to sync the standby with Primary. Will this method reliable?
Apologies to ask many questions but i found no single document covering this detailed process.

Both the links are for applying patches/upgrades for Oracle Database. Apologies i didn't clarify the requirement. It's for EBS R12. So i need to sync the apps tier with primary when physical standby in place.
Kindly validate below procedure with rsync utility
After running the Middle Tier and Database Pre-clone.
To synchronize Synchronize the Appropriate File Systems to Standby,
rsync –av <$APPL_TOP> <standby_host>:<$APPL_TOP>
--rsync-path=/usr/local/bin/rsync
/usr/local/bin/rsync –av <$COMMON_TOP> <standby_host>:<$COMMON_TOP>
/usr/local/bin/rsync –av <$ web ORACLE HOMEs (10.1.2)> <standby_host>:<$ web ORACLE HOMEs (10.1.2)>
/usr/local/bin/rsync –av <$TOOL(10.1.3)> <standby_host>:<$COMMON_TOP>
Synchronize the database tier file system including <RDBMS ORACLE_HOME>/appsutil directory.
/usr/local/bin/rsync –av <RDBMS ORACLE_HOME>/appsutil <standby_host>:<RDBMS ORACLE_HOME>/appsutil
Reconfigure the Standby Middle Tier File Systems
When the file system synchronization is complete, reconfigure the standby file systems. Log onto each of the standby middle tier systems as the APPLMGR user and execute the following commands:
cd <COMMON_TOP>/clone/bin
perl adcfgclone.pl atTechStack <INST_TOP>/appl/admin/<Standby CONTEXT_NAME>.xml
To complete the configuration of environment run AutoConfig using the following commands:
cd <APPL_TOP>/ad/12.0.0/bin
adconfig.sh contextfile=<INST_TOP>/appl/admin/<standby context>.xml run=INSTE8
AutoConfig will report errors regarding to database connection, these errors can be ignored as the database is unavailable.
Step 4.4.11 - Reconfigure the Standby Database File Systems
If you had to synchronize the apps utilities on the database server in the prior step, you should also reconfigure the database server. As the ORACLE user on each database node of standby database tier, first stop the listener if it is running, then execute the following commands:
cd <RDBMS ORACLE_HOME>/appsutil/clone/bin
perl adcfgclone.pl dbTechStack <RDBMS ORACLE_HOME>/appsutil/<Standby CONTEXT_NAME>.xml

Difference between Manual Standby and Data Guard Broker..

With Data Guard Broker:

See especially why you want to use the broker:
http://download.oracle.com/docs/cd/E11882_01/server.112/e17023/concepts.htm#i1013106
In short: You should have a good reason if you do not use the broker, because it is the officially recommended way to maintain Data Guard. It is even required for some features like Fast-Start Failover.

Need to apply PATCH&HF for other nodes??

Hi guys,
I got one confuse. I have host A to be DB HOST(ORACLE 9205), Host B& host C to be cluster nodes for EP6 SP2 PATCH4 HF7. I installed portal & CM on HOST B, applied PATCH4 HF7, then applied CM PATCH 4 HF5. very thing work fine than I installed addtional dialog instance at host C.
the problem is , when host C 's server node startup, there is a CM startup error in the console log. the error msg. is :
com.sapportals.wcm.repository.ResourceException: CM Startup failed: CM startup failed: Failed to init. connection pool configuration: Failed to init. connection pool configuration: missing plugin /cm/utilities/connection_pools
I make sure the config_local.properties file is ok, SAPWCM's password is ok too.
after I install the dialog instance, I didn't apply any patches for host C , is that right? please guide me

Hi Jochen,
My problem is due to I got 4 server nodes, the connections to the ORACLE is too much. There is a note mentioned how to increase ORACLE's default process and session no. Search "oracle process 80" at OSS you can find that note.
wish this can help you.

Physical Standby: Monitor Transport/Apply Lag

Hello Forum
I'm using 10.2.0.3 and my aim is to ensure having a physical standby db (to an two nodes RAC) to switchover/failover to in (hopefully) every disaster.
What are your best practises regarding to monitor transport/apply lag of a physical standby instance (data guard) within Grid control? How many seconds to set the treshold to? Or is there no need to monitor this? I have to say that I was able to achieve my aim in every (rare) disaster in the past.
I saw that there already two metrics in Grid Control (standard = not set).
Currently I got the following values measured:
Apply Lag (seconds): from 0 - 31
Transport Lag (seconds): from 0 - 8
Thanks for your advice

Question - Oracle Physical Standby

Oracle 10.2.0.3 database running on row logical disk (row device) with two thread RAC cluster with CRS and AIX-HACMP implemented on two nodes running AIX6.1 OS
My question can one create simple Oracle Physical Standby (without data guard etc) Database on different AIX node which do not have HACM and CRS RAC but simple non RAC Oracle S/W installed
If this can be done how the single one thread non RAC Oracle database will consume and apply two thread archive logs and keep itself to sync with primary database changes.
Can you please provide some details if this is feasible or not? My guess is for this to happend ORACLE RAC setup with RAC enable Oracle S/W is must with one active thread and other thread can be inactive and not in use.
Thanks –

A standby database is not Data Guard ... it is a standby. Data Guard is a specific automated implementation of a Standby. You can do whatever you wish manually if you prefer pain to comfort.
Personally I'd throw away the IBM stuff and go with Data Guard: It is far superior and does something critical HACM can not do ... guarantee that what is replicated is logically correct. Replicating corruption has no value.

Create Data Guard Using ASM Managed RMAN backup

we have an oracle database 11.1.0.7 working on Windows server 2003 (64bit). The storage in ASM managed (same 11.1.0.7). Our total database size is 4TB.
I will have to create a physical standby database (Data Guard) of this instance. Now I am having issues on how to transport my RMAN backup pieces (which is also ASM managed).
I cannot do an over the network RMAN backup because it will take months to complete.
We have external 4 hard disks (2 TB each). But my RMAN backup pieces are ASM in format.
Any ideas on how to easily create a data guard in this set up.

Supplemental logging with Oracle 10gR2 Streams and Data Guard

Hello,
I have a environment with Oracle DB 10gR2 and Physical Standby with Data Guard DR Conf. Right now, this environment is going to be extended to a replication schema using 2-way Oracle Streams Replication (for replication to the central office from this branch office, other branchs will be added soon). The primary DB will be replicated to the other primary DB (in the remote central office).
So, there is my question: It's completly necesary to specify Supplemental Logging on the sources databases (primaries) for setting 2-way Streams Replication?, and, if it's completly necesary, then, do I can set Supplemental Logging on primaries without affect theirs physical standbys, or do I need to do something special?
Thanks in advance.

Sorry, it's repeated. 'cus browser connection problem.
