Single-instance manual standby for a three-node RAC database

Hi all,
I am wondering how it is possible to create a manual standby database for a rac primary database.
Oracle versione is standard edition 11.1.
I have experience creating and managing manual standby for single-instance database; I am wondering if and how I can instruct the single-instance standby database to discover and apply the three redo threads that I will copy from the primary site to the standby site.
Should I use rman to catalog all the archived log on the standby site ?
Should I configure many LOG_ARCHIVE_DEST_n parameters to point to many different path, one for each primary instance (i.e. one for each redo thread), and let rman automagically discover all the archived logs ?
Should I configure only LOG_ARCHIVE_DEST_1 , put archivelogs from all threads in the same folder, and let rman automagically discover all the archived logs ?
Thanks for every answer!

Hi,
indeed i catalog all transfered archive logs in front of the recover process.
During the tests i believe (iirc) i was unable to recover from transfered archivelogs without catalog them first. But this statement is out of my mind, i am not 100% sure for this, sorry.
Some more details.
Because it is a standard edition, i have to use on the RAC side ASM. So our normal scripts to transfer archivelogs from primary to standby are obsolete.
So i decided to put the whole standby thing into the database. Now the primary database uses external scheduler jobs to do the work. The standby side is not using ASM, so there is no need to handle the logs in any special way.
The steps are:
1. Get SCN from primary and standby
2. Transfer the logs for the gap from ASM to "normal" filesystem.
3. Transfer (and compress, if not in LAN) to standby archive dest
4. Catalog on standby side
5. Recover on standby side
6. Delete on normal filesystem (on both sides, but on standby with a delay of 2 days just to be sure)
The steps on the standby side are both using the primary scn from step 1 as a parameter to avoid error messages during the catalog or recover call.

The problem here is probably with your standby init.ora file.
When you create a standby database, the db_name parameter must NOT change. It has to match the primary database. So in your case, db_name ='PROD' and your db_unique_name='DPROD'...

How to Create Manual Standby for a Oracle 11g RAC with ASM to Single Instan

Hi All,
I have a task to configure a Single Instance Standby Database with ASM for 2-node Primary RAC+ASM database.
Version using : 11.1.0.6 Oracle 11g --- *" STANDARD EDITION "* Please note datagaurd will not be supported in standard edition.
Primary database - 2 -Node RAC using ASM storage (All datafiles, redologs, controfile and archive logs)
Need to setup a single instance standby database manually and than using scripts to transfer the archive logs from primary server to standby server to do recovery time to time.
Please let me know if there are any configuration document(s) which can help me to set the manual standby? or need your kind help to give your valuable ideas how to go in above situation.
Thanks in advance

Well if the archive logs are stored in ASM on the primary nodes, you almost definitely want to be using RMAN to access them. Then to transfer between primary and standby there are many options, this is essentially the step that Data Guard takes care of - so if you (and I) are running Standard Edition, this is the part to "worry" about.
I'm not really sure what you mean by this:
As in standard edition the archive destination will be on ASMI don't think the Edition of Oracle (Standard or Enterprise) dictates where and how you store your archive logs, but it's possible I've misunderstood what you mean...SE dictates that database storage for RAC will be ASM, including archive log files. Anything else is not officially supported. I haven't tested but it may be that you can use LOG_ARCHIVE_DUPLEX_DEST to specify a local filesystem for archive log files as well.
If that doesn't work you'll have to script rman "backup as copy" jobs regularly and then transport the results of that.

By the way, it seems Robert has been pretty helpful, it's polite to give him some points dude. And since this is your thread, not mine, give him a "helpful" from me too :p
El DBA
Incidentally if you are forced down the RMAN backup as copy route then this will likely throw your current backup retention strategy somewhat, you'll need to think carefully about when an archivelog can be deleted following backup, how many times it might be backed up and so on. I do understand, and have argued for, the use of SE RAC. I also understand and have argued for and implemented manually managed standby a number of times. However by the time your primary database is a RAC instance and you need a standby for DR etc then you really have to look very seriously at whether Standard Edition is still the right investment or not. You will be spending a lot of DBA time managing and troubleshooting this, and you will find that it is less reliable than the off the shelf solution. I suspect that you are very close to the point where an EE installation becomes a worthwhile investment here.

3 node RAC database need to build standby database

Running an external job at the specific node out of a 2 Node RAC database.

Hi. all.
I created a job , which runs an external script, by using dbms_scheduler.
Our database is 2 node RAC database(10.2.0.2.0).
The external script exists at a only one Node(Node 1).
select status,instance_id, additional_info
from dba_scheduler_job_run_details
where job_name='TEST_EXPORT_JOB'
shows that jobs which run on Node 2 failed.
Of course, the external script does not exist on Node 2.
I would like to force the job to ALWAYS run on Node 1.
How can I do that? Is there any ideas?
Locating the script on Node 2 is not the option.
Best and Regards.

Hi,
In the upcoming 11g release there is an easy solution for this - a new attribute instance_id for a job.
For 10g there is a workaround. Basically you create a service with just the one instance you want the job to run on. Then create a job class pointing to that service. Finally have your job be in the job class you just created.
If you create a service and job class per instance you can get jobs to run under whichever instance you want.
Hope this helps,
Ravi.

For 4 node RAC database on Exadata x3-2, how many scan IP I should assign?

We want to build a 4 node RAC 11gr23 on exadata x3-2. Oracle only recommend 3 ip for scan listener. by previous observation of non-exadata RAC, seems each node will spread randomly one Scan Ip address. So if we assign 3 ip to one scan listener, how that will work on a 4-node RAC?
Thanks

You're welcome
by Load balancing
Oracle RAC databases increase load balancing by using the single client access name (SCAN) for the cluster to balance connections among all instances in a cluster database. SCAN also adds location independence for the databases, so that client configuration does not have to depend on which nodes are running a particular database or database instance.
http://docs.oracle.com/cd/E11882_01/install.112/e48195/undrstnd.htm#RIWIN607
Based on the environment, the following actions occur when you use SCAN to connect to an Oracle RAC database using a service name. The numbered actions correspond to the arrows shown in Figure 7-1.

Migrating single instance SAP and Oracle 11.2.0.1 database to Oracle RAC

We have a single instance SAP Netweaver environment on Oracle 11.2.0.1 database and want to migrate to Oracle 11.2.0.1 RAC and ASM. The documents are for 11.2.0.2 and later but we want a way to:
1. Migrate single instance SAP and Oracle 11.2.0.1 instance to ASM
2. Configure the environment as four node Oracle 11.2.0.1 cluster
Thus far, I have:
1. Installed clusterware 11.2.0.1
2. Installed four ASM instances
My questions:
1. We want to migrate the single instance database to same server and extend to four node cluster and ASM
However, current SID for SAP and Oracle must remain the same. The problem I have is that the target database name needs to be same as source on same physical host.
2. How would I use RMAN to migrate the single instance database to ASM for 11.2.0.1?
3. How would I use rconfig after this step?

Issue- we have RAC 11.2 clusterware listener using SCAN and listeners for all four clusterware nodes.
When we try to run the following RMAN command to migrate the single instance Oracle 11.2.0.1 datafiles it fails:The failure says: "+RMAN-10038: database session for channel ORA_DISK_1 terminated unexpectedly+". And this in itself does not tell you what the actual problem encountered is.
4- How to register the single instance with all four ASM instances and network services to resolve the above issue?Register what instance? ASM does not need databases or instances to be registered. It is a storage management layer. The cluster (grid infrastructure) layer is the one that deals with the registration (and management) of the various services and resources on that grid (e.g. ASM instances, database instances, SCAN and VIP, Listener services, etc).
5- Do we need to first run rconfig utility against single Oracle 11.2.0.1 instance to register with clusterware services BEFORE using RMAN to perform the datafile migration to ASM?Never used rconfig. See Support Note +RCONFIG : Frequently Asked Questions [ID 387046.1]+ for details.

How many control file should be created in ASM for ORACLE 4 nodes RAC

We have a oracle 10G(10.2.0.4) database with 4 nodes locates ASM in redhat linux5.
The vendor created this RAC system with database.
I saw below infornation as

It seems that each node with one control file.
I got a feedback that vender claimed SAN is very reliable.
I am new person for database at ASM for RAC.
Could you make a explain for this condition? Do I need to add ( mirror) another 2 control file into ASM?
The Oracle recommands that at least 2 contril files( best 3 files) in different place. This is true for signle instance.
How about RAC that database locates in ASM?
Please help me!!
Jim

You are fine using the standard three controlfiles in ASM, four is fine too, but it does not need to be tied to the number of instances as all the instances in a RAC database use the same controlfile (and its copies). ASM knows the controlfile type and will stripe each one in 128k pieces across as many volumes as it can. I much prefer to have my controlfiles in ASM, it prevents accidental deletion and generally makes DBA life easier.

Modifying a service in a 3-node RAC database

Hello,
I have a 3-node rac 10.2.0.4 here under Windows 2003 x64.
I created, months ago, a service that have 1 preferred instance, and 1 available instance.
Now I have to change it, so it does not have an available instance anymore, just 1 preferred instance, because the client wants it to run only on this node.
After looking up in the 10.2 manual, I could not find the exact command to accomplish the job. Have you done this and can you shed a light ?
Thanks.

Hi, thanks for your answer, but no, each node has 2 instances only, ASM and Database.
But they changed their minds, instead of keeping togheter the service SRV3 on NODE3, now we need that, when NODE3 restart or something, and come back, the service be relocated to NODE3.
This does not happen automatically, Oracle says we have to code the "srvctl relocation" command using some callback mechanism to automate fallback. Is there an url or paper or so that explains how to do it ?
Thanks.

Enable Archivelog Mode On 2 Node RAC DATABASE

hi,
We are having 2 Node Rac 10g Database Installed on Windows.
Currently the Database is in Non Archivelog Mode.
I want to convert it to Archivelog Mode.
I come to know the steps to convert cluster database to Archivelog mode.
i.e.
set archive parameters like Disk Location and Archivelog File format.
then Convert the database in Exclusive Mode
ALTER SYSTEM SET cluster_database=FALSE SCOPE=spfile;
then
C:\> srvctl stop database -d <Global_DB_SID>
then enable Archivelog Mode.
SQL> STARTUP MOUNT;
SQL> ARCHIVE LOG START;
SQL> ALTER DATABASE ARCHIVELOG;
SQL> ALTER DATABASE SET cluster_database=TRUE SCOPE=spfile;
SQL> SHUTDOWN IMMEDIATE
C:\> srvctl start database -d <Global_DB_SID>
But I am confuse with Do i need to RUN this commands in both the nodes seperatly or only on any one node.
Please Reply,

I'm not sure why you have the non-standard service_name racdb2.
Somehow it looks like you both don't understand the RAC concept, and didn't understand my answer. I had to correct several things I already corrected in my previous response. I'm not sure why I'm not getting through.

Single instance cmd prompt for multiple wshshell.run

Hi,
I need to have only one command prompt open for two wshshell. run command
for eg
wshShell.Run "cmd.exe /C cd D:\"wshShell.Run "cmd.exe /C cd C:\"both the command should display in single command prompt window
Need to execute some 100 commands in a single cmd prompt like this

The CD commands were obviously just example commands
not the commands you really want to run. Even if these
commands were able to successfully change the current
directory in some other context than the command prompt
window, that context could only entertain one current
directory at any given time.
If you want to run a sequence of commands synchronously
(one after the other) in the command prompt window, you
could do as Forest suggested for a short sequence:
wshShell.Run "cmd.exe /c cd D:\ & dir & cd E:\ & dir"
or you could put the commands in a batch file:
wshShell.Run "cmd.exe /c mybatch.cmd"
or just:
wshShell.Run "mybatch.cmd"
You would, of course, need to ensure that the location
of the batch file was properly specified or deduceable.
If you want to run a sequence of commands asynchronously
(all at the same time), well, that is not how the command
prompt window itself works. You would need to launch
separate processes, each doing whatever task is assigned
it. If these are batch files, each will run in its own
command prompt window; if these are vsbcript files, you
could run them with wscript.
Or, if you were to switch to powershell, you could run
them as separate powershell jobs.

OCR and Votinging Disk File Permissions for NFS 2 node RAC cluster

This is a fresh reinstall of Oracle 11gR2 Clusterware on Red Hat Enterprise Linux 64bit and I'm using NFS as my shared storage.
I've create three file systems /ocrVote01 /ocrVote02 and /ocrVote03 as NFS share and exported them to two nodes that will use them as shared OCR and Voting Disk. Currently I'm getting errors when I run root.sh
I've done the following:
chown rac:dba -R /ocrVote01 /ocrVote02 /ocrVote03
It appears that the root.sh script is trying to create a directory /ocrVote01/storage and getting permissions denied.
Any idea why Root can not create this directory?
root.sh is also getting error permission denied at /u01/gridinfra/11.2.0/GI/crs/install/crsconfiglib.pm at line 4478
Any Ideas on what file permissions should be set for /ocrVote01 /ocrVote02 and /ocrVote03 ?
