Standby Database for GRID instance

Hi All,
I have a requirement from a client to provide a Standby database (Physical or Logical) for the GRID control instance. Baffled by this, I tried to explain that the GRID instance is very small and may not require a standby. The client is adamant.
So, has anyone had any experience (experimental or otherwise) of configuration of a standby for GRID?. If so, how? and which would be a feasible option, Physical or Logical?
Any feedback is appreciated.
Regards,
Timothy.

The search function on here isn't great, it took me longer than I care to admit to find you this:
OMS question on Physical Standby database
If you need clarification on anything, shout. Like I said, its a pain to do.

Procedure for Standby Database for SAP ERP 6.0

Hello All,
We are using SAP ERP 6.0 with Oracle 10g with AIX 5.3.
We are planning to setup a standby database for our SAP ERP 6.0 production system as part of remote DR site using Oracle Data Guard.
I was under the assumption that i can first install an erp 6.0 (ABAP) system using homogeneous system copy from my erp 6.0 (ABAP) production system and then start configuring oracle dataguard.
But the System Copy Guide "System Copy for SAP Systems Based on SAP NetWeaver 7.0 SR3 ABAP" has mentioned that "You cannot create standby systems with a system copy".
Please suggest the best practise or the procedure for creating standby database for SAP ERP 6.0 system. Iam not looking at the steps for creating a pure oracle 10g standby database, but with SAP instances as well.
Thanks in advance.

Error while creating standby database for ebs prod database

Hi,
We are getting error while trying to create a standby database for EBS database by using RMAN DUPLICATE commands,
Steps followed:
1.) Backup the primary database (Ebs PROD db). This was done on 12-Mar-2012
***RMAN backups are scheduled to run @10:00 pm every night. Flash Recovery Area has been configured and backup is taken at this location
everyday.
2.) Tar the backupset, autobackup, archivelogs etc in FRA .... and copy this to the target server (STANDBY).
*** Copy(oracle rdbms binaries and FRA) completed @12:00AM on 14-Mar-2012
3.) Tried to create standby database by using RMAN duplicate on 14-Mar-2012
RMAN> rman sys/sys@PROD auxiliary /
RMAN> duplicate target database for standby dorecover nofilenamecheck;
After, some time the RMAN DUPLICATE process errors out with,
ORA-19563: header validation failed for file
We are not sure about the cause of this error. While searching in Metalink, we got several notes (ex, 352074.1) but all the causes stated for this error
are not applicable in our case. We double checked our instance to confirm this.
We have also found that in PROD database there are 65 datafiles and after the RMAN DUPLICATE errors out in the targer server (STANDBY) the RMAN managed to restore 51 datafiles before erroring out.
# Please note PROD database was also backed up on 13-Mar-2012. We have a suspicion that backup on 13-Mar may be a possible cause for this error but we are
not sure.
Need suggestions if there can be any other possible causes???
We are in a fix and it would be appreciable if we get some quick suggestions..

Rupdipt

When opening the file to be placed in a copy or backup set, to be inspected, or used as the target for an incremental restore, its header was not recognized as a valid file header for a file of the indicated type (data file, archived log, or control file) belonging to the current database.
Kindly Ensure that the correct files are being specified for the copy or backup operation.

Creating a RAC standby database for a single instance database

Dear All,
I have a task of migrating a 500GB single instance database to a two-node RAC database with a little downtime at hand. My migration strategy is to:
1) Create a RAC physical standby for the Single Instance database
2) Switchover to RAC standby.
Primary and Standby OS and DB configurations:
OS: Windows Server EE 2003 (64-bit)
DB: Oracle 10g Database Release 2 (10.2.0.4)
Oracle 10g Clusterware Release 2 (10.2.0.4)
To create a RAC standby, I will:
a) Install Clusterware (10.2.0.1)
b) Install Database (10.2.0.1)
c) Patch both Clusterware and Database (10.2.0.4)
d) Create ASM instance for both the nodes (+ASM1 & +ASM2)
e) create standby controlfile on primary
f) Move standby controlfile, RMAN backup of primary, pfile, listener.ora, tnsnames.ora, password file to standby host-1
g) make necessary changes to the pfile on standby host-1 like cluster_database, instance_name, thread, ...
h) mount standby database and restore backup
Kindly validate my steps and if there already exists such a document then please do provide me with a link.
Regards

Can I use data guard to create a RAC standby database for a non RAC primary

Hi,
we need to RAC our production database but the normal methods will mean a long outage. It is possible to create a standby as a single node RAC database and when ready do a graceful failover to the standby database and open it for business. The next step would be to create another RAC node from this on the original server.
servers are already cluster aware, using ASM etc
Oracle 10.2

Yes, you will be able to setup RAC stnadby for a non-RAC Primary. For primary it just needs a available destination for redo shipping it doesn't matter whether it's RAC enabled or not. And ofcourse you are using 10.2 anyway only one node will be running MRP and that is too in standby mount mode.
However since you have are using You may follow below sequence.
1. Setup a new standby as RAC enabled.
2. Perform a switchover.
3. Shutdown the Old primary (which is standby now).
4. Install CRS and RDBMS on the old primary and it's new node.
5. Modify the cluster_database=TRUE and cluster_database_instances=<required number of instances>.
With above modification mount the standby database in standby mode and start MRP.
6. Introduce the database and instances to the OCR using SRVCTL add command.
7. Once you your database is synchronized with Primary do a switchover.
9. Now you can repeat step 3 to 6 on the other site too. <- if you need your secondary site to be RAC enabled too
10. Finally both the sites should be RAC enabled.
Hope this is helpful!!!
Thanks,

Manually Setting up a Standby Database for RAC Environment

Hi,
I am a Junior DBA so apologies if this sounds like a silly question.
We have production 11g Extended RAC environment setup. Management have asked for a separate single instance database be setup as a standby DB on a separate 'cold' server in case we lose complete connection to both sides of the RAC. I read up on Oracle Data Guard and presented this as a solution, but they seem adamant about manually going in and copying out the latest backup and archive logs over to the standby database.
Can this be done? I mean, can ASM managed backup files and archive logs from one database be simply copied out of the backup directory and imported into a completely separate database as easy as that?
We are using ASM to manage to data files on the RAC. My understanding is that we cant manually access the files on an OS level when using ASM, but maybe I am wrong. Any help or opinions on this would be greatly appreciated.
Rgs,
Rob

Hi,
Can this be done? I mean, can ASM managed backup files and archive logs from one database be simply copied out of the backup directory and imported into a completely separate >database as easy as that?Yes, but depends on DB version.
what is the DB version.
from 11g you have cp command so there is a possibility to copy generated archive logs to standby location, so that you can apply..
In 10g there is no such option. you need to create a standby database. with automatic shipping
Thanks

Creating standby database through Grid Control.

Hi,
I want to know if source database which we term as primary database goes down during Db creation process when given option of "Perform a live backup of primary database" during Add standby wizard in Grid Control. Please let me know if people have already tested it in their environments.
I appreciate you all for looking into my forum.
Regards,
Gaurav

No, one of the options for performing this task is to create from a Live db.
A couple of things to note here:
You must be using spfile
If you are not using the default port of 1521 then you must also have the local_listener parm set
I recommend using the "db_unique_name" option to make it easier to manager in OEM (for the target name)
Hope this helps,

Standby Database for Oracle 8.1.7 Std Ed

Hi, I am using Oracle 8.1.7 std ed with W2K Adv Server. Both primary host and remote host using the same version of oracle and OS.
So far both oracle path are identical and the standby folder is same with primary and I don't think I need to add the db_name_convert and log_name_convert into my standby parameter file.
I have make a consistent backup from primary to standby and also create the standby control file from primary. However, I am having the problem on setting up the tnsnames.ora and listener.ora for both primary and standby? Can someone here give me the sample on configure those ora file? Say example

Instance (Primary) : PRMY
Host Name (Primary) : STBY
DB_NAME : PRMY
SID (Primary) : STBY
Instance (Primary) : STBY.
This error message is once i am going to connect the standby database via SQL*Plus using sys/change_on_install@STBY, error ORA-12154: TNS:could not resolve service name displayed. However, I managed to login follow by set oracle_sid=STBY and connect as sysdba.

How to open a standby database for use?

First, let me state that I am not a DBA nor am I a systems guy; I'm a software developer.
At work, we recently built a new virtualized db server by cloning our disaster recovery (DR) database server. The DR database was kept in 'standby' mode (I think that's the correct term) and was synched with production daily via archive logs.
So now, we have this new virtualized server that has a clone of that 'standby' database on it, and I need to 'open' that database so that it's usable (ie, no longer a standby db). How do I do that?? We recently lost our DBA so this has fallen into my lap.
From searching the web, I've found all sorts of instructions. It seems that I need to issue some commands via SQL*Plus? But as what user? From where do I issue these commands (I assume from the virtualized server)? And what are the commands?
This is Oracle 10g v10.2.0.3.0 running on Solaris 10 for x86.
Thanks!
Dave

Hi Dave, I do this each time we do a DR test. I have 10.2.0.3 in physical standby mode.
First, I make sure I have flashback turned on (here is what I've done):
connect / as sysdba
startup nomount
alter database mount standby database;
alter database flashback on;
alter database recover managed standby database through all switchover disconnect using current logfile;
exit;Activate the physical standby:
alter database recover managed standby database cancel;
alter database activate physical standby database;
alter database open;
exit;When completed with DR test we return the database back to physical standby mode:
Find the SCN when the physical standby was activated (this is so we can flashback to that point in time)
select standby_became_primary_scn from v$database;connect / as sysdba
flashback database to scn <this is the value returned from above>;
alter database convert to physical standby;
shutdown immediate
startup mount
alter database recover managed standby database disconnect from session;
exit;I hope that helps,

Is Fast Incremental Backups possible on standby databases for 10.2.0.5?

Hi,
Can anyone help to clarify if it is possible to have Fast Incremental Backups on 10.2.0.5 standby . The information in MOS (Doc ID 262853.1) stated:
Note : Fast Incremental Backups were not possible on standby databases till 10g
but from 11g Fast Incremental Backups are available on standby databases also.
It sounds ambiguous.
Thanks

The answer is No, due bug 6130588.

Quick question: redundant OMS databases for Grid Control

Dear Friends,
I am wondering if it is possible to configure redundant OEM Management Server databases on separate servers and how would that be done?
I don't think it is possible to have an agent write to more than one OMS database, so how is it possible to have our OEM management server redundant?
Is running DG the only option?
Thanks.
Ji Li

Damorgan:
I thought I remembered doing this at a previous site that I worked a few years ago, but I don't remember how I did it.
Will I need to configure dual listeners, or use separate ports for the dual agents?
Do you know where there might be instructions for how to set up and run dual agents on the same server?
Thanks again.

How to setup a Multi-instance standby database?

I was asked to setup a multi-instance standby database for a multi-instance primary database. I understand that only one of the instance will apply redo logs from the primary database, but how about the other instance? Should I mount that instance just to update the standby control file(the control file is not located in shared file system with the cluster server) even if it isn't going to apply any redo logs?
I am so confused now. Hope somebody will help me on that. Any document or tutorial will be helpful too.
Note that I am not using dataguard.
Thanks in advance

Hi,
You can set up multiple instance standby..where in each instance will receive the archive logs from correpsonding primary instance. Keep them on shared location (say ASM) so that one of the instances from where recovery is started can access the archive logs and apply it.
So basically
Primary instance A <----- send archive to ---> Standby A
Primary instance B <----- send archive to ---> Standby B
Start managed recovery on A
Standby A --- > Apply archives for instance A and B
