Register the RAC standby instances in CRS

Hi All,
Is there any document or artical for how to register the Standby RAC instances in CRS ? we have tried it but after reboot of the server
it mounted the standby instances but not started the media recovery.So can you pls share your ideas ?
Regards
Kamal

Use the srvctl utility to add the database/instances. When you do this, if you tell CRS that the database you are adding is a Standby, then it will start managed recovery automatically on startup. The srvctl commands can be found here:
http://download.oracle.com/docs/cd/E11882_01/rac.112/e16795/srvctladmin.htm#CDCGICIF
To add the database, do something like:
srvctl add database -d db_name -o oracle_home -p spfile_location -c RAC -r PHYSICAL_STANDBY -s MOUNT -t IMMEDIATE
Once the database has been added, add each node's instance similar to the following:
srvctl add instance -d db_name -i instance_name -n node_name

User connections to the RAC/standby instances

Before I setup the client failover practices, I tested user connection to my RAC instances.
1st I shutdown one instance, of course all connection will go to remaining instance.
However when both RAC instances are up and running, any new connection goes to instance 1.
Is this normal ? Is that the way supposed to be?

Is this normal ? Is that the way supposed to be?If any new connections are coming.. if load balancing configure properly these sessions should be shared across the cluster.

Steps for data guard RAC primary RAC standby

Hi,
I have some doubt in configuring data guard for rac DR to rac primary.
1) In RAC DR, physical standby will be in RAC before starting data guard for RAC Primary , right?.
2) While configuring RAC DR , should one node be down in standby?.
3) After creating the auxiliary database in standby, i mean restoring the rman backup from staging directory in DR,
Shall we have to register the services(database,instance,asm,etc..) to CRS(OCR)?. If yes ,Why?.
4) After DR configure over , Shall i shut/down one node?. Should all the nodes in DR be in up , while applying logs to
standby ?.
If anybody have made the setup and have the prepared document , requesting you to share with me.
Thank you very much,
Sunand

Hi Sunand,
Please follow the following My Oracle Support (MOS) Document ID:
MAA - Creating a RAC Physical Standby for a RAC Primary [ID 380449.1]
For further details, see the referred documents in previous post. Try practicing on VMWare because it will give you the flexibility for creating snapshots to save your work. Please see the answers for your question below:
Q1. In RAC DR, physical standby will be in RAC before starting data guard for RAC Primary , right?.
Answer: Yes, this is recommend but not mandatory. You can add a second node later on.
Q2. While configuring RAC DR , should one node be down in standby?
Answer: Yes, there are some database configuration commands that should be run in exclusive mode. You can start the remaining instance(s) after DB creation. Do not forget to set CLUSTER_DATABASE parameter to TRUE. Also, all instances except one should be close while performing switchover/failover.
Q3. After creating the auxiliary database in standby, i mean restoring the rman backup from staging directory in DR, Shall we have to register the services(database,instance,asm,etc..) to CRS(OCR)?. If yes ,Why?
Answer: Yes, this is recommended for RAC configuration to take advantage of high availability services.
Q4. After DR configure over , Shall i shut/down one node?. Should all the nodes in DR be in up , while applying logs to
standby ?
Answer: You can start up all the instances after DR creation. In this case if your one node goes down log apply services will continue to apply changes in DR.
Hope, this helps to clear your questions.
Regards,
Shahid

Rebuild RAC standby

Hi all,
Can anyone give any insight into the steps to rebuild a RAC standby?
My guess is as follows:
The following is all on standby side
1. activate standby r/w
2. Test failover
3. use dbca to delete the database (dbca unregisters instances and services from OCR)
4. use RMAN to recreate the duplicate standby
--creation of logs needs to be done..
5. re-register the instances and services with the OCR
Does seem about right?
Can anyone recommend a document detailing the instructions for re-building a RAC standby after activation?
Thanks in advance.
john

I need a high level view... like task list..
Its a rebuild of an 11gR2 physical RAC standby on Linux RH4.
My guess is I can use dbca to delete the activated standby and then use RMAN to recreate the standby and then manually register the instances and services to the OCR.
My query is the steps with the RMAN creation of the new standby, do I do it in single instance mode and then add standby logs then modify the spfile to reflect cluster_database = true and then register the services and instances and put it in managed standby mode etc..
The bottom line is I need to some offical documentation for the steps involved in recreating an activated RAC standby.
I will contact oracle support.

RAC Standby Database rebuild

Hi
Current 10.2.0.4 Setup is with Dataguard Broker (Unix/No OEM Setup):
Rac Primary 2node cluster
Rac Standby 2node cluster
The rac Standby Database are going to be opened read/write.
Then will require a rebuild of standby ie delete db files and duplicate db using rman
1) My questions is how do I rebuild of a rac standby database with an existing enabled dg broker?
2) Are there any documentation on the steps to follow.
3) Should the dg broker config be dropped or just disabled and if so at which stage?
Config on Rac primary should be kept to a minimum as its being used so no outage expected here.
Regards
Me

Have you given any thought to using flashback (depending on how long your standby will be open for read/write)? You could (before you open read/write) copy your dr*.dat files (broker config files), stop the broker and create a guarenteed restore point. After you have finished and ready to convert back to standby you would flashback your database to the restore point, convert back to a physical standby, restart the broker and shutdown. Restore the dr*.dat files to their location and then startup the standby. From there it should fetch the logs from the time the broker was down and catch back up.
If you would rather rebuild, again you would need to take the broker out of the equation and use RMAN to create a clone for standby and then once in place you would reconfigure the broker (may be able to just restore the dr*.dat files from before the open operation but unsure.

Oracle ORA_16000 when trying to add standby instance to existing rac node

I attempted to use dbca to add a new standby instance to an existing cluster. The cluster is 4 nodes, Linux RHEL 5.3 Oracle 11.1.0.7. Also using ASM, asmlib, ocfs2 and shared block devices.
ASM instances are up and functional on all nodes. current config appears to be running normally and correctly.
I have a 4 instance database running on the cluster. I also have 3 physical standby active data guard instances running on 3 of the nodes. I wanted to add a new ADG instance to the 4th node.
While running dbca I received ORA-00604 and ORA-16000.
The active data guard database was open (read only) and redo apply was on. I am using data guard broker as well, but not grid control.
Does anyone have a procedure for adding an instance in this environment? Do I need to have the standby in mount state? If dbca won't work does anyone have a manual procedure for adding a new instance?
Thanks

1a.
Add undo tablespace to support additional node.
Re-check space for DATA1 on nusclust16007 and /dbdata/ORADB on sun16109.
As of Thursday, May 21, 2009 the DATA1 asm group has 53,584M free.
As of Thursday, May 21, 2009 the /dbdata/ORADB has 77G free.
In a separate terminal window on nusclust16007 run the following in sqlplus
CREATE UNDO TABLESPACE UNDOTBS4 datafile '+DATA1' SIZE 13300M AUTOEXTEND ON ;
This will take a long time to create this tablespace. Please minimize the window after submitting the ddl and move on to the next step.

2. Start Oracle Universal Installer:
Go to CRS_home/oui/bin and run the addNode.sh script on one of the existing
nodes. Oracle Universal Installer runs in add node mode.
The Oracle inventory on nusclust16007, nusclust16008, and nusclust16036 are found under:
/home/oracle/oraInventory
Use a X windows enabled session (The OUI takes 33 minutes)
cd /apps/ocr/oracle/product/11.1.0/crs/oui/bin
./addNode.sh

4. After this is done crs_stat -t will show nusclust160## in the crs i.e.
I see:
Name Type Target State Host
ora....160##.gsd application ONLINE ONLINE sun...160##
ora....160##.ons application ONLINE OFFLINE
ora....160##.vip application ONLINE ONLINE sun...160##
Do not be concerned about ora.nusclust160##.ons being OFFLINE, as that will be fixed shortly in a step that follows this one.
5. As oracle :
On nusclust16007:
cd /apps/ocr/oracle/product/11.1.0/crs/bin
./racgons add_config nusclust160##:6251
This should take about one second to run.
If it says that it has already been added to the OCR you are fine.
If it hangs, you may need to reboot all servers to clear this issue.
6. Insure new node is properly added to ocr by running
On nusclust16007:
ocrdump
Check for the entries that show:
[DATABASE.ONS_HOSTS.nusclust160##.PORT]
ORATEXT : 6251
7. Check that your cluster is integrated and that the cluster is not divided into
partitions by completing the following operations:
On nusclust16007:
cd /apps/ocr/oracle/product/11.1.0/crs/bin
./cluvfy comp clumgr -n all -verbose
Should see Verification of cluster manager integrity was successful.
8.
Use the following command to perform an integrated validation of the Oracle
Clusterware setup on all of the configured nodes, both the preexisting nodes
and the nodes that you have added:
AS oracle on nusclust16007:
cluvfy stage -post crsinst -n all -verbose
Post-check for cluster services setup was successful.
good: Post-check for cluster services setup was successful.
9.
On nusclust160## as oracle run the following:
cd /apps/ocr/oracle/product/11.1.0/crs/bin
./crs_stat -t | grep OFFLINE
If you see this:
ora.nusclust160##.ons application ONLINE OFFLINE
then run this:
./crs_start -all
After:
./crs_stat -t
ora.nusclust160##.ons application ONLINE ONLINE nusclust160##
If you see the above then you can move on the next step.
Adding database binaries to the nusclust160## server and setting up the listener.
1.
From nusclust16007:
Open an X window (The OUI part takes 13 minutes)
cd /apps/dbs/oracle/product/11.1.0/db_1/oui/bin
./runInstaller -addNode ORACLE_HOME=/apps/dbs/oracle/product/11.1.0/db_1 $*
You should get a prompt to specify a new node, in this case you should see nusclust160## where you will need to put a check mark beside it.
2.
from nusclust160##:
Eventually you will be prompted to run the following as root on the new node
On nusclust160##
cd /apps/dbs/oracle/product/11.1.0/db_1
./root.sh
Running Oracle 11g root.sh script...
The following environment variables are set as:

3. verification
Now set up the .bash_profile and .asm profile to on nusclust160## to support new ORADB4 and +ASM4 instances for the oracle userid.
On nusclust160##:
cp .bash_profile .bash_profile.bak
On nusclust16007:
sftp nusclust160##
put .bash_profile
On nusclust160##:
vi .bash_profile
change ORALCE_SID to ORADB4
cp .bash_profile .asm
vi .asm
change ORALCE_SID to +ASM4 in .asm file
which sqlplus
Should show the path below is $PATH environmental variable is set correctly.
/apps/dbs/oracle/product/11.1.0/db_1/bin/sqlplus
On nusclust160##:
oifcfg getif
This should show:
ce4 10.333.248.192 global cluster_interconnect
ce5 222.65.125.128 global public
4.
Run Netbackup Oracle Agent link script.
As oracle make sure ORACLE_HOME is fined.
env | grep ORACLE_HOME
then
cd /usr/openv/netbackup/bin/
./oracle_link
ls -al $ORACLE_HOME/lib/libobk.so
should show:
/apps/dbs/oracle/product/11.1.0/db_1/lib/libobk.so -> /usr/openv/netbackup/bin/libobk.so64.1
5.
On the target node, run the Net Configuration Assistant (NETCA) to add a
listener. Add a listener to the target node by running NETCA from the target node and
selecting only the target node on the Node Selection page.
I shall do the following on nusclust160## using X Windows
Now before I do this I see:
crs_stat -t
ora.nusclust160##.gsd application ONLINE ONLINE nusclust160##
ora.nusclust160##.ons application ONLINE ONLINE nusclust160##
ora.nusclust160##.vip application ONLINE ONLINE nusclust160##
Connect to nusclust160## and open up X windows session.
netca
Choose Cluster configuration.
select nusclust160## as the node to configure.
Choose Listener configuration, then Add.
When it prompts you for a listener name choose LISTENER as it will append _NUSCLUST160##(server name) to end of the LISTENER name to make a complete listener name.
At this point you will have listener to support the new node in the crs.
now
crs_stat -t
will show:
ora....0#.lsnr application ONLINE ONLINE nusclust160##
ora.nusclust160##.gsd application ONLINE ONLINE nusclust160##
ora.nusclust160##.ons application ONLINE ONLINE nusclust160##
ora.nusclust160##.vip application ONLINE ONLINE nusclust160##
At this point the necessary crs entries for gsd, ons, vip, and the listener on nusclust160## all we need now are the ORADB4 and +ASM4 instances added.
III. 7/11/2009 7:40 AM Sat [120 min] NTTA DBA
Use NON dbca method to create additional instances on the nusclust160## server. This will involve a complete shutdown of all RAC instances.
1.
Undo tablespace creation was taken care of in Step I,1. Check on the progress of the creation of tablespace UNDOTBS4 in the minimized window. Should see tablespace on primary and physical standby databases.
2. First we shall set up the +ASM4 instance on nusclust160## and add it to the cluster.
On nusclust160##
cd $ORACLE_HOME/dbs

sqlplus '/ as sysasm'
startup
create spfile from pfile='/apps/dbs/oracle/product/11.1.0/db_1/dbs/init+ASM4.ora' ;
shutdown immediate ;
startup
show parameters spfile
6. Now that we have a running asm instance add it the cluster.
On nusclust160##
srvctl add asm -n nusclust160## -i +ASM4 -o /apps/dbs/oracle/product/11.1.0/db_1
srvctl enable asm -n nusclust160## -i +ASM4
7. Now that we have an asm instance let's set up a database instance.
On nusclust16007/ORADB1 :
alter system set cluster_database_instances=6 scope=spfile ;
alter system set instance_name=ORADB4 scope=spfile sid='ORADB4' ;
alter system set instance_number=4 scope=spfile sid='ORADB4' ;
alter system set local_listener=LISTENER_ NUSCLUST160## scope=both sid='ORADB4' ;
alter system set thread=4 scope=both sid='ORADB4' ;
alter system set undo_tablespace=UNDOTBS4 scope=both sid='ORADB4' ;
alter database add logfile thread 4 group 28 ('+REDO1', '+REDO2' ) size 100M ;
alter database add logfile thread 4 group 29 ('+REDO1', '+REDO2' ) size 100M ;
alter database add logfile thread 4 group 30 ('+REDO1', '+REDO2' ) size 100M ;
alter database add logfile thread 4 group 31 ('+REDO1', '+REDO2' ) size 100M ;
alter database enable public thread 4;
Need to add 5 groups to support standby
So at the end of the day 900M will be added to REDO1(29,577M free) and 900M will be added to REDO2 (29,577M free).
8. Set up init.ora, listener.ora, and tnsnames.ora for ORADB4 on nusclust160##.
a. init.ora set up
cd $ORACLE_HOME/dbs
vi initORADB4.ora
SPFILE='+DATA1/ORADB/spfileORADB.ora'
b. add entries to tnsnames.ora:
ORADB4 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust160##-vip)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORADB)
(INSTANCE_NAME = ORADB4)
ORADB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16007-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16008-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16036-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust160##-vip)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORADB)
LISTENERS_ORADB =
(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16008-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16036-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust160##-vip)(PORT = 1521))
LISTENER_NUSCLUST160## =
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust160##-vip)(PORT = 1521))
ORADB_PRIM =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16007-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16008-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16036-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust160##-vip)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORADB)
c. add entries to listener.ora, The entries for most of this file should be set already, just insure modifications that need to be made are made.
SID_LIST_LISTENER_NUSCLUST160## =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /apps/dbs/oracle/product/11.1.0/db_1)

(ADDRESS = (PROTOCOL = TCP)(HOST = 222.65.125.###)(PORT = 1521)(IP = FIRST))
9. Reload the listener.
lsnrclt
set current_listener LISTENER_NUSCLUST160##
reload
exit
10. Check audit trail, add instance to cluster, and start db instance.
a.
Check for audit directory and start the instance.
/apps/dbs/oracle/product/11.1.0/db_1/rdbms/audit
If this audit trail directory does not exist then create it.
b.
srvctl add instance -d ORADB -i ORADB4 -n nusclust160##
srvctl modify instance -d ORADB -i ORADB4 -s +ASM4
srvctl enable instance -d ORADB -i ORADB4
Will probably show: PRKP-1017 : Instance ORADB4 already enabled.
c.
sqlplus '/ as sysdba'
startup
**Because the cluster_database_instances parameter requires the complete shutdown of all instances in the cluster, you might have an issue when it attempts to start the instance. If you receive an error then run:
srvctl stop database -d oradb
sqlplus '/ as sysdba'
startup
shutdown

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

WebLogic Error : Registered more than one instance with the same objectName

HI there, I'm facing a big problem. I have two environments installed on the same physical machine.
I have ALSB and WLI servers running out there.
Environment 1 - WLI port running at 7011 domain name : stp_wli_domain and ALSB port running at 8011 domain name: stp_alsb_homo1 - folders- stp_wli_domain / stp_bea_alsb_homo
Environmnet 2 - WLI port running at 7211 domain name : stp_wli_domain2 and ALSB port tunning at 8211 domain name : stp-alsb_homo2 - folders - stp_wli_domain2 / stp_bea-alsb_homo2
Everything was working fine, but these days I had install new deployments on both environment and I got this error :
java.lang.IllegalArgumentException: Registered more than one instance with the same objectName : stp_wli_domain:ServerRuntime=wli_wls01,Name=stp_wli_domain,Location=wli_wls01,Type=AIRuntime new:com.bea.wlai.management.AIRuntimeMBeanImpl@bcf22dc existing com.bea.wlai.management.AIRuntimeMBeanImpl@de02e6c
The weird is : There is no same object name, as you can see, domains are different, folders are different and ports are diferrent, including multicast addresses.
Have you guys seen this before ?
I'm under pressure here, 'cause some projects had stopped to work.
Please I would appreciate any help.
Tks.
Edson

HI there, thanks for attention..
See ...
There's a lot of confusion with these env's .
I did not built this, so... I'm cleaning my hands.... anyway... :)
I must fix....
Well basically if we have two env's, so we have different project each one right ?
Ok, but I was told that if you have on the same network and same physical machine the name of AdminServer as "AdminServer" in all domains, so it goes with problems... I never heard about it... but is a good practice you put the names for example :
WLI - WLIAdminServer
ALSB - AlsbAdminServer
WLI2 - WLiadminServer2
ALSB2 - ALsbAdminServer2
I would do it.. this way..
But how it wasn't me...
We got..
WLI - WliAdminServer
ALsb - AdminServer
WLI2 - AdminServer
ALsb2 - AdminServer
Have you got it ?
So... I was told that this could be a problem, almost all AdminServers with the same name... guess what ?Some Projects are back to work. but not at all.. only some.. so I 'm breathing better now... but I would like to know if you seen this before ?
I would appreciate your help again.
Unfortunately there's no detailed stack trace to track this
Tks.

Registering the ACFS filesystem with CRS

Grid version:11.2.0.2 on Solaris 10
I want to register the ACFS filesystem with the CRS. Which option should I use ; Option A or Option B ?
Option A.
From
http://www.unbreakablecloud.com/wordpress/2011/02/01/acfs-file-system-setup/
You can add the file system using the following srvctl command:
#srvctl add filesystem -d /dev/asm/fs1-334 -v FS1 -g ACFSDG -m /fs1 -u oracle
Start the file systems
#srvctl start filesystem -d /dev/asm/fs1-334 -n node1 (please sure to change node1 to whatever your nodename)
When the system gets rebooted the file systems will be automatically mounted by Oracle Clusterware.or
Option B.
Example borrowed from oracle-base
http://www.oracle-base.com/articles/11g/acfs-11gr2.php
After , creating the Disk group, Creating the volume and enabling it. The following commands are run
-- creating the ACFS
/sbin/mkfs -t acfs -b 4k /dev/asm/acfsvol3-301 -n "ASMVOL3"
--- mounting the ACFS
$ /sbin/acfsutil registry -f -a /dev/asm/acfsvol3-301 /u01/app/oracle/acfsmounts/data_acfsvol3
Do these commands (option 2) register ACFS filesystem with CRS ?In option A, I am curious why he is running srvctl from root (I can see # sign ) ?
Another related question:
Is there any advantage in having ACFS registered with CRS ?

Omega3 -
Both options result in a mount point that is managed by CRS. I refer to this as a managed mount point.
The difference really comes down to what you want to do with it.
If you want a mount point that you can use on all nodes of the cluster and that you can create dependencies on, then use srvctl.
If you want a mount point that is node-local, then you can use acfsutil registry.
If you don't have either of those situations, then you can use either.
Generally, I recommend using 'srvctl'.
As pointed out, you can easily create the resource using ASMCA.
The advantage of this method is that you can create other resources, such as for user defined programs, and create STOP and START dependencies on the ACFS resource. This will ensure that the ACFS file system is mounted before those programs stop and start.
Also, keep in mind that if you are planning on putting large numbers of ACFS file systems in the registry, you may run into some timing issues. The ACFS registry resource has a finite TIMEOUT value, and may run out of time to look at all the file systems\volumes and ensure that they are operating as expected. This is another case where the single file system resource has an advantage.
In either case, add it and forget about it - it should just work. :)

Will Nodeapps register the listener service of RAC database?

Hi Friends,
In 10g RAC will Nodeapps register the listener service of RAC database?
because if i bring down nodeapps the listenener is also going down

ora.rac1.gsd application OFFLINE OFFLINE

Regards,

Hi,
This is expected behavior. The default listener (listener_nodename) could be starte and stopped with nodeapps.
srvctl listener is mainly for specific listeners that are other than default.
http://docs.oracle.com/cd/B19306_01/rac.102/b14197/whatsnew.htm#sthref6
If you create additional Listeners with non-default names, in other words, with names other than the name listener_nodename where nodename is the name of the node on which the Listener resides, then you must start and stop these Listeners with SRVCTL commands.

How to find which instance in the RAC cluster the application is connected

How to find which instance in the RAC cluster the application is connected to ?
Raees

well if you know the user through which your application is connected to instance, you can easily find out by querying gv$session view.
select inst_id,sid,serial#,program,username from gv$session where username is not null;

2 Node RAC standby database

Hi,
I am planning to create a 2-node RAC physical standby database which uses ASM from 2-node RAC production database. I am familiar with RMAN duplicate (11g) network based backup to create the physical standby database, but not sure how this will work to create 2-node RAC standby with ASM.
Could any help me with the document ID which describes how to create a RAC standby database using ASM as storage.
Source:
OS: Linux 64 bit
Oracle: 11.2.0.1
RAC/ASM: yes/yes
Target:
OS: Linux 64 bit
Oracle: 11.2.0.1
RAC/ASM: yes/yes
Thanks in advance!!
Regards,

Hi
You can follow following...
1.Install crs.
2.Create ASM instance at standby site...
3.Prepare parameter file for standby database.
4.start database instance in one node at nomount state..
5.create standby control file at primary database...
6.Copy and paste created control file at primary to standby site..
7.Copy control file at file system and modify location of control file at init<SID>.ora.
8.start standby database mount state..
9.create backup text backup controlfile at primary site...
10.shutdown standby database,change location of controfile inside ASM.. and place nomount state...
11.Create controfile through text backup controfile...
12.backup primary db and paste it in standby site..
13.Use RMAN to place datafile inside ASM..if you not using RMAN for backup and restoration purpose..
14.start standby database in mount state and recover through MRP or foreground process..
15.use SRVCTL to register ASM instances..database and database instances.
For standby database of RAC..there can only be one node up...So..remember you can start instance of one node only...
Hope this will help U.

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!!!

SWPM RAC DB instance install error on srvctl add database -d

Hello,
We are currently installing a distributed NW 7.31 system with Oracle RAC on ASM.
SCS ran successfully ,and now we are trying to install db instance.
During phase 'Create database' the installation stops with error code 1.
The log is:

I don't know why the SWPM asks for the spfile if this is a fresh installation. The only file that exists is initISP.ora
Perhaps SWPM was supposed to create an spfile<SID>.ora from init<SID>.ora?
I hope someone out there has encountered this before

What are the RAC DBA daily tasks?

Hello Experts,
What are the RAC DBA daily(routine) tasks?
Thank you.

Hi Friend,
Good Query..
1. Make sure that all database instances are available.
Log into each instance and run daily
2. Checking CRS status
bash-3.00$ ./crs_stat -t
3. Checking Volumes Informations in each instances.
bash-3.00$ df –h
4. Verify success of database backup:
a. RMAN backup/Data Pump Backup/Cold backup
5. Check the Archive Log file locations in each instance
6. Check the Archive Log file location volume sizes in each instance
7. Check Alert Log files (Any ORA_600, oRA_07445 etc..) in each instance
8. Check the Statspack / AWR Report Peak hour reports
9. Check the ASM INSTANCE status in each instance
10. Check disk groups space and limitation
11. Always use EM and ADDM reports for performance health checks and analysis
12. verify the DR sync (if applicable):
13. If DR site is available :
a. Check to determine if latest archive logs have been applied to the database by looking at the alert
log file for the standby(DR) database.
14. Review contention for CPU, memory, network or disk resources:
a. Work with system administrators to develop methods to review contention for these resources.
15. Maintain Complete Database Details (Data Files locations, Control file locations, Redo Log file Locations etc...)
a. If any changes in production database or DR-Site database update manuals.
16. Check OCR and VD backup locations. (If possible take manually OCR and VD backup)
17. Check CRS logs in each instance
18. Check Listener Logs in each instance
19. If you are using RMAN backup, Use both the instances while taking RMAN backup (Multiple Channel allocations in Instances)
20. Weekly restore the RAC backup in Single Instance Database (If RAC setup is not available)
Hope it helps....
Thanks
