RAC & DataGuard (Physical Standby)
Hello all,
I'm trying to get a high level overview of how RAC & DataGuard would behave in the following configuration. I've written down my understanding of how things would work. Please correct me if I'm wrong.
1) 2 node RAC (Primary Database) with a single instance physical standby.
a) Same standby related init.ora parameters would have to configured on both primary rac nodes.
b) The redo apply service at the standby would merge the redo from the 2 threads from the primary and apply it to the standby to keep it in sync.
c) During switch over only one primary RAC instance should be up besides the standby instance.
d) During switch back again only one primary RAC instance should be up besides the standby instance.
e) During failover ofcourse both primary instances would be down which warrants the fail over.
2) 2 node RAC (Primary) with a 2 node physical standby
This where it gets complex and I'm not really sure how a,b,c,d,e would be in this scenario. Appreciate if you could shed some light on this and list what
a,b,c,d,e would look like in this scenario.
I'm assuming that only one instance in the standby RAC should be up when the standby is in RAC configuration for the redo apply to work.
Also, if there is a white paper that details step by step procedure for setting up the above 2 scenarios, please let me know. So far I was able to find only the MAA white paper but that was not very helpful. If you can prescribe a good book for RAC & DataGuard that would be great too..
Thanks for your help>
1) 2 node RAC (Primary Database) with a single instance physical standby.
a) Same standby related init.ora parameters would have to configured on both primary rac nodes.Usually rac nodes share their spfile on a shared diskvolume or through ASM. So they have identical DG parameter anyway
b) The redo apply service at the standby would merge the redo from the 2 threads from the primary and apply it to the standby to keep it in sync.Correct
c) During switch over only one primary RAC instance should be up besides the standby instance.
Sounds logical to me
Edit: In fact during normal operation both RAC nodes are up, so during switchover they are both active too
It is the configuration that matters. As soon as the standby is becoming primary, it might be that it talks only to one RAC node for its log-apply files
d) During switch back again only one primary RAC instance should be up besides the standby instance.That single was the only one running in step c.
e) During failover ofcourse both primary instances would be down which warrants the fail over.Correct. Keep in mind that during a failover the RAC config would be deconfigured from the DG setup and has to be added back again as standby.
You might have to take a look at: http://www.oracle.com/technology/deploy/availability/pdf/MAA_WP_10g_RACPrimarySingleInstancePhysicalStandby.pdf

No. RAC primary to RAC Standby would mean both nodes are up on both side. PrimNode1 send its redo logs to StandbyNode1 and the same for PrimNode2 and StandbyNode2

RAC physical standby in dataguard
Hi All
How many nodes need to be on the mount state in the RAC physical standby ? for example if we have RAC of 4 nodes in the physical standby . do I startup all of them in mount state or only one and what about the other they should be open or we shut them down ?
ThanksHi,
-- assuming version 10.2
If your primary database is a rac all the instances will send the redo information but even if the standby database is also a rac only one will receive/apply the redo information.
How many nodes need to be on the mount state in the RAC physical standby ? for example if we have RAC of 4 nodes in the physical standby . do I startup all of them in mount state or only one and what about the other they should be open or we shut them down ?
The instances will be mounted, if the working instance fails another one will be able to do the job.
Best regards
Phil

DataGuard Standby 環境で db が open できない.
DataGuard Standby 環境で db が open できなくて困っています。
詳しい方いれば、原因と対処方法を教えていただきたいと思います。
create した spfile が正確に読み込まれていないことが原因のようなのですが。。
なぜ読み込めないのかが分からない状態です。
pfile を読み込んだ起動は可能ですが、spfile を読み込んだ起動の前提条件とは、
何なのでしょうか。単に整合性が取れていないだけなのか、それとも、、。

よろしくお願い致します。
ps.
ORA-12154 は整合性の問題であるので、それを合わせれば消えると思っています。
そもそも RAC を前提としていたのですが、それを standalone に置き換えて検証始めた結果、
こうなってしまっています。
open できない原因が ORA-12154 だったりして。。
■ プライマリの場合
○ open するほうは、シンプルに以下だけで open することが確認できる。
が、db_name を変更した関係で
「ORA-12154: TNS: 指定された接続識別子を解決できませんでした」
が出続けている。
ORA-12154 は db が open できない原因とは無関係かもしれない。

Hi,
We have configured a RAC production system and an standalone standby database.
Last week, we had trouble with our ESS subsystem and we have to failover.
Rigth now we solve the problem with the ESS subsysytem and the RAC enviroment is up and running but the database is no updated because is at the moment that we had the problem.
So, we want to back to the initial configuration (RAC primary database and standalone standby).
I want to know is this can be possible with only a backup/restore? (standby database cold backup and then restore the database over the RAC environment) and then reconfigure our standby database?
Or which steps should we follow to do this?
Thanks in advance,
GeraldMy question is:
Is it possible to setup a standby database on a RAC environment with 2 nodes? I've searched through MOS but didn't find any information about that...Yes, it is possible. Refer this

Rebuild RAC phsical standby with RMAN
Hi all,
Can anyone give any advice as to rebuilding an ACTIVATED RAC physical standby using RMAN? We have been able to revert the db with flashback but I need to know the rebuild method.
Is there any extra steps with the OCR?
I am guessing the steps might be:
1. Use DBCA to delete the newly activated standby.
(The DBCA will clean up the OCR components)
2. Use RMAN to duplicate a physical standby database.
3. Register the instances and services with the OCR.
Can any comment on this and suggest a decent task list from oracle as to the method.
Thanks in advance,
jd

Configuring Non RAC physical standby fro RAC
Hi,
EBS-R12i , Oracle Database:11g
We are in project design phase and following is the hardware setup for Critical banking domain:
Database (2 node RAC)-Solaris 10
Application server server (2 server) -Solaris 10
Web server (2 server for Failover)= RHEL
For DR
Database (1 node)-Solaris 10
need to know
1.What are the best practice to implement this kind of setup and steps to configure DR as Non-RAC physical standby for RAC database server.
2.What are implication if we go for single node except failover node unavailability for DR.
3.What are the steps of Switchover in this case.
4.What's the recommended backup solution for this setup of 8-10 Terabyte database with db growth rate of 50% per year.1.What are the best practice to implement this kind of setup and steps to configure DR as Non-RAC physical standby for RAC database server.There really aren't any differences in setting up your physical standby in a non-RAC configuration. It is after the physical standby is setup that it is converted to a clustered database, if desired. In your case, you do not desire the conversion.
The best place to start for best practices in setting up your physical standby is the Oracle documentation on the subject.
http://download.oracle.com/docs/cd/E11882_01/server.112/e17022/toc.htm
2.What are implication if we go for single node except failover node unavailability for DR.The major implications are that you will be running with less horsepower after a failover. So depending on your DR resources, you may have to scale back application access. In addition to less resources, you will also have less availability because you only have one node. Should that node then fail, you will not have a node to failover to.
3.What are the steps of Switchover in this case.The steps are identical if the physical standby is a single node or multiple nodes. These steps are outlined in the Oracle documentation.
4.What's the recommended backup solution for this setup of 8-10 Terabyte database with db growth rate of 50% per year.What are your recovery requirements? Without knowing your recovery requirements, a valid backup solution cannot be determined. How much data loss can you afford in the event of a failure? Do you have data that can be read only? In the event of a failure, how long before you are required to be up and running? Are you required to restore and recover at an offsite location?

Hi everyone, i hope somebody can help me.
I have a configuration RAC (2 nodes) and 1 dataguard (standby physicall).
Both run in Linux Red Hat 4 Update 7.
My quesion is, Probably i need to do a flashback database in the RAC for some test so Must i do some in my dataguard? or it is transparent?
Thank you very much for your time.
Regards.Hi,
I think you need to test. Whether it is RAC or single instance, asnwer will be same. In worst case you may need to setup the data guard again. Data guard supports DDL from primary to standby database, but I did not read anything about flashing back the primary in this setup. We may benefit from your experiment.

Hi folks,
I m having setup with 2 node RAC primary and 2 node RAC Dataguard on 10.2.0.4.0. Dataguard setup is working fine. Dataguard is setup with Standby Redo log group with managed recovery. Due to network issue network issue the transferring archives & applying on standby couldnot take place.The network issue is sorted but now the primary and standby are not in sync.
I am new with RAC and dataguard combined.Can you proivde suitable document or steps how i can manually sync both.Hi;

RAC + dataguard architecture/setup metalink notes
Looking for RAC & dataguard configuration for one db ...
Hi,
I think it is rather worth to look around on the [Oracle Maximum Availability Architecture site|http://www.oracle.com/technology/deploy/availability/htdocs/maa.htm] for whitepapers than checking the Metalink (Well, at least I like MAA much better the Metalink)
Hope this helps.

Conflicting PROCESSES values on 10g RAC+Dataguard
Hi peeps,
So i've set up a RAC+Dataguard environment for testing, and have recently encountered ORA-12518 errors; quite a few Google results suggest checking V$RESOURCE_LIMITS for any resource problems. Upon checking i noticed that the MAX_UTILIZATION for resource PROCESSES is set to 71, with CURRENT_UTILIZATION set to 70;i found this strange 'coz i specifically increased the PROCESSES parameter to 300 when i set up the db; i ran SHOW PARAMETER PROCESSES and verified it was set to 300.
Shouldn't i be getting the same values?
tiaHello badkuk,
The max_utilization column means the greater value of this resource since last instance startup. See it on http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_2050.htm#REFRN30206
Also see the description of error message at http://ora-12518.ora-code.com
I think the root cause of this error was not processes parameter.
Take a look on Metalink note ID 556428.1
*"In general ORA-12518 occurs if there is a resource problem , may be on the listener side or on the Database server. It indicates a condition where the process is not able to make any more memory allocations either due to non-availability of resource or the process has reached the 32 bit (VM Size) limit"*

Next log sequence to archive in Standby Database (RAC Dataguard Issue)
Hi All,
I just had implemented Data Guard in our server. My primary Database is RAC configured, but it is only single node. The other Instance was removed and converted it to Developement Instance. For the reason I kept the primary as RAC is when I will implement dataguard, my Primary Database is RAC with 7 nodes.
The first test is successful, and I was able to "switchover" from my primary to standby. I failed in the 'FAILOVER" test.
I restore my primary server and redo the setup.
BTW, my standby DB is physical standby.
When I try to switchover again and issue archive log list, below is my output.
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 38
*Next log sequence to archive 0*
Current log sequence 38
SQL> select open_mode, database_role from v$database;
OPEN_MODE DATABASE_ROLE
MOUNTED PHYSICAL STANDBY
===============================================
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 38
*Next log sequence to archive 38*
Current log sequence 38
SQL> select open_mode, database_role from v$database;
OPEN_MODE DATABASE_ROLE
READ WRITE PRIMARY
In my first attempt to switchover before I failed in "FAILOVER" test, I also issue +archive log list+ in both primary and standby database, and if I remember it right, next log sequence on both should be identical. Am I right on this?
Thanks in Advance.
Jay AOr Am i just overthinking on this?
Is dataguard only looking for the current and oldest log sequence? -
Add datafile dataguard from physical RAC to standby RAC
Hello we have a 3 node cluster RAC 10g on the primary and RAC 10g on the standby.We use as db storage ASM wich is configured over raw devices and file management omf.The same groups DATA and FRA on both servers.STANDBY_FILE_MANAGEMENT is manual.
We need to add a datafile on the primary safely.Can you offer me some ideeas?
Thank you!Hello;
Change STANDBY_FILE_MANAGEMENT to "auto" before you add the file and then leave it set to "auto". ( set this to AUTO on both Primary and Standby )
STANDBY_FILE_MANAGEMENT enables or disables automatic standby file management.
If you leave it set to MANUAL you may create unwanted file in $ORACLE_HOME/dbs and cause issues with the MRP process.
Best Regards
