Multiple Standby Databases on same RAC nodes.

We have a 3 node Oracle 10gR2 RAC production environment on site A and a 3 node Oracle 10g RAC standby environment on site B. Both use like HW and OS - HP BL45p with RHEL AS 4.x.
Can we have heterogeneous standby databases(logical and physical) running on the same RAC nodes?
Can the 2 apply processes (MRP-manageed recovery process & LSP-logical standby process) coexists on the same set of nodes in a cluster at the same time. Are there any conflicts or limitations?
Is there any documentation that supports this?

Would Active Data Guard give you the best of both worlds?
The caveat might be your SID_LIST_LISTENER setup.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(PROGRAM = extproc)
(SID_DESC =
(global_dbname = <database1>_DGMGRL.yourdomain)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(sid_name = <database1>)
(SID_DESC =
(global_dbname = <database2>_DGMGRL.yourdomain)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(sid_name = <database2>)
I have a server with ten standbys on it currently and no issues.
As long as the version is the same you should be good.

Multiple standby database about FAL_SERVER and FAL_CLIENT parameter in DG

Hi,
I am little bit confused about FAL_SERVER and FAL_CLIENT parameter in Data Guard.
We are planning to configure multiple standby database in Data Guard environment. Let Assume that, i have production db named as 'PROD' and multiple standby name like standby1,standby2, standby3.
My Environment is:_
DB Version: 11.2.0.1
OS Version: OE5LU6
So in this case how to specify above Net service name in spfile on production server and also on other standby server.
Kindly Suggests me.
Regards
Athish

AthishFAL_CLIENT is Oracle TNS service of the local system and FAL_SERVER is Oracle TNS service of remote system.
if you have three standby databases of primary , then from primary you must have three values in FAL_SERVER so that archives will be send to the all destinations.
and From the stadnby database, FAL_SERVER should be the oracle TNS service where you receiving the archive log files,
Note:- If you have RAC primary then mention each service differentiated by commas as shown example below.
From standby to Primary RAC:- FAL_SAERVER='PROD1','PROD2'
These parameters are dynamic, so that you can alter them at any time.

Can we create standby database on same server as primary database

I have Oracle 10g Rel2, OS Windows server 2003. Can I create standby database on same server on which we have our primary database?

The INSTANCE: WHen I create a VM Image, I specify the name (like a SID), configuration (like PFILE), and location (like ORACLE_BASE/oradata/ ...)
And just like Oracle with which I can have 2 or more instances running on the host (if there is sufficient memory and other resource), I can have 2 or more VM Images running on my host.
And just like Oracle, if I have insufficient resources, things get slow like molasses in the middle of winter.

Is it recommended to support multiple DBs and Instances on same RAC nodes

Customer wants to install multiple databases on the same set of 3-nodes essentially making all these database 3-node rac databases on Sun fire servers.
Is this a recommended approach? What are the pitfalls?
Can this be done effectively without using local containers (which are not supported for RAC)?

The Customer would save significantly on Licencing if he does not have to add Processors into the three nodes.
Processor Based Licences don't count the number of databases and instances, only the number of CPUs (Processors).
Setting up seperate Clusters requires that many Processor Licences.
However, using multiple Standard Edition RAC installations (Linux and ASM) would have been another option.
I have run multiple databases on a single Cluster in 9iRAC. I am sure that there are customers running multiple databases in a single Cluster in 10gRAC. You'd have only one CRS and one ASM Home in each node but it may be possible to have separate Database ORACLE_HOMEs in each node as well.

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

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:

Use a X windows enabled session (The OUI takes 33 minutes)
cd /apps/ocr/oracle/product/11.1.0/crs/oui/bin
./addNode.sh

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...

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

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##

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 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 =

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
srvctl start database -d oradb
shutdown
srvctl start instance -d ORADB -i ORADB4 -o open

Restore RMAN Backup in Different Database on Same RAC

We have 11gR2 2 node RAC on Linux. ASM and OMF is used for database. The database on it is backedup using RMAN.
We want to test the RMAN backup by restoring it to a new database on same server.
Can someone guide me to steps on how this can be achieved. I'm afraid this should not affect the actual database.
Thanks a lot.

Hi,
Yes, this can be done without disturbing your source db. Need more information on your DB structure (datafile asm diskgroups), all you need to do is restore as single node and convert to rac, since you want to test rman restore, you can restore to single node to prove your RMAN backups are intact.
Changes in init.ora
==============
db_file_name_convert= ("source dir structure","target dir structure")
log_file_name_convert=("source dir structure","target dir structure")
cluster_database=false
event="10298 trace name context forever, level 32"
_no_recovery_through_resetlogs=TRUE
Set new database sid (export ORACLE_SID=NEW_SID)
sql>startup nomount;
rman auxiliary /
rman>duplicate database to "NEW_SID" backup location "Your RMAN Backup location";
The above are very high level general steps, please do take other steps into consideration as per your environment.

Creation of Standby database on same host

Hi All,
I am using oracle 9.2.0.1.0 on windows XP machine.
*I want to create the standby database for my primary database on same machine.
But both tha data base is heaving diff instance as well as the diff database name say "ASHU" for primary & "TEST" for standby database.
I took the backup of all datafile and copied it in the standby location.
Generate the standby control file also and copied to the standby location.
But when i am going to start the standby database it is giving the below error:
SQL> startup nomount;
ORACLE instance started.
Total System Global Area 135338868 bytes
Fixed Size 453492 bytes
Variable Size 109051904 bytes
Database Buffers 25165824 bytes
Redo Buffers 667648 bytes
SQL> alter database mount standby database;
alter database mount standby database
ERROR at line 1:
ORA-01103: database name 'ASHU' in controlfile is not 'TEST'
How to rectify it? Please help me
(* This is only for learning pupose , that's why i am going to create both on same host"

alter database mount standby database
ERROR at line 1:
ORA-01103: database name 'ASHU' in controlfile is not 'TEST'

You do not change the dbname of the physical standby database. They always must have the same name as the primary.
Here is a snippet from my standby initialization file for a 9i installation. Notice the parameter LOCK_NAME_SPACE that was replaced in 10g with DB_UNIQUE_NAME
db_file_name_convert=('E:\PRIMA','E:\PHYST')
db_name='PRIMA'
instance_name='PHYST'
service_names='PHYST'
lock_name_space='PHYST'
log_archive_dest_1='LOCATION=E:\PHYST\ARCHIVE'
log_archive_start=TRUE
log_archive_format='%t_%s.arc'
log_file_name_convert=('E:\PRIMA','E:\PHYST')Kind regards

Standby database in same computer

I have made standby database in different computer then in production database in similar path and it is working.
But whenever I try to make it in same computer it gives me error. I have gone through the oracle documentaion.
But still I can't.
Any suggestion on Node

I still get the problem.
I have created a prod database with archive log mode and archival enabled
I shut down it and copyed the
"oradata/prod to oradata/stdby",
"admin/prod to admin/stdby",
"initprod.ora to initstdby.ora" and
"pwdprod.ora to pwdstdby.ora"
Then I have added a service name "stdby" with net8 easy config
Now I have created a new instance stdby with "oradim -new -sid stdby"
now In "Prod init.ora" file I have added
log_archive_start = true
log_archive_dest_1 = "location=e:\Oracle\oradata\stdby\archive"
log_archive_dest_state_1 = ENABLE
log_archive_dest_2 = 'SERVICE=standby1'
log_archive_dest_state_2 = ENABLE
global_names = false
Now I have started the prod database and created a standby controlfile
alter database create standby controlfile '\oradata\stdby\stdby.ctl'
now In "Stdby init.ora" file I have added
db_name = "prod"
instance_name = stdby
service_names = stdby
control_files = ("e:\Oracle\oradata\stdby\stdby.ctl")
log_archive_start = true
log_archive_dest_1 = "location=e:\Oracle\oradata\stdby\archive"
log_archive_dest_state_1 = ENABLE
standby_archive_dest = 'e:\Oracle\oradata\stdby\'
db_file_name_convert = ('\prod\','\stdby\')
log_file_name_convert = ('\prod\','\stdby\')
lock_name_space = 'stdby'
Now IN standby when I do
SQL_stdby>>startup nomount pfile='E:\Oracle\Oracle8i\DATABASE\initstdby.ora';
SQL_stdby>>alter database mount standby database;
SQL_stdby>>RECOVER AUTOMATIC STANDBY DATABASE;
Up to this it works
Now when I start prod database
SQL_prod>>startup
it gives me the error
ORA-01102: cannot mount database in EXCLUSIVE mode

Hi,
I have to create 2 standby databases of a single primary database,
where can i get the stpe for the same?
Thanks

What about FAL_CLIENT parameters in primary?
how to set the values of the above parameter in priamry for second standby database.?
Thanks,In your case do need setting FAL_CLIENT/SERVER in primary database,set these parameter correctly in your standby database.Refer below note

Creating physical standby database on same machine with dataguard

hi every one
i m new in oracle databases,
i read documentation to create physical standby databases,

now i want to create standby database on the same machine in some other drive configured with datagurd
virtual machine
OS windows xp
database oracle 9i
plz reply me how i do this
explain clearly step by step.
plz reply me in detail

When you need to have the standby database on the same server as the master, use lock_name_space in the init.ora.
This parameter permits this to occur without having to worry about changing the db_name.

Multiple Standby Database

Hello Folks,
DB Version : 10.2.0.4
OS : Solaris 5.8
I am planning to configure 2nd standby database (Physical ) for one of the my production database.
Right now it's configured with 1 physical standby database. If any one has previous experience or any document link please update the forum.
Thanks for your time.

primary database parameter
*.fal_client=' '
*.fal_server=' '
standby database 1
*.fal_client='stby1'
*.fal_server='primary'
standby 2 parameter
*.fal_client='stby2'
*.fal_server='stby1','primary'
more that that we have to set log_archive_dest_n parameters correctly
and db_file_name_convert and log_file_name_convert parameters , if it is needed.
configuring listener.ora and tnsnames.ora files ....
i plan to post a documentation of creating and adding physical and logical standby databases in different hosts..
please wait this month end , i plan to post it in my blog

3 node RAC database need to build standby database

Respected DBA's
I have create 3 node rac architecture now i want create a single instance standby database is anyone tell me the steps or any documentation to consult.
thanks

See the [ MAA Home page|http://www.oracle.com/technology/deploy/availability/htdocs/maa.htm#Database] for " [MAA 10g Setup Guide: Creating a Single Instance Physical Standby Database for a RAC Primary Database|http://www.oracle.com/technology/deploy/availability/pdf/MAA_WP_10g_RACPrimarySingleInstancePhysicalStandby.pdf] "

Physical standby database in RAC system

Hi EXperts,
We have a 4 nodes 11.2 cluster system. i will set a data guard as a disaster recovery mothods.
As a physical standby database set, does we need to configure same nodes (4 nodes) in other city as primary database cluster system?
Can we set physical standby database is in 2 nodes cluster system and primary database is in 4 nodes cluster system?
Thanks explaining!
Jin

Can we set physical standby database is in 2 nodes cluster system and primary database is in 4 nodes cluster system?Yes. You can setup 2 node RAC as physical standby and also with different memory parameters. But, the only issue is when DB failover from primary to standby, the applications connect to 2 node RAC in place of 4 node RAC and may be overloaded.
