RAC Migration non ASM to ASM

Hi
I have to perform a migration project
of a 4node RAC cluster to new hardware,
this RAc cluster has a 2 node DR
The new hardware will have the same os as
the current one .The catch is that the database is
currently using a unix file system and it has to be
migrated to ASM. Can some1 please guide me with best
possible way to achieve this....any links or documentations
appreciated....If any1 has more questions on this please let me know
Thankyou

Check metalink note 252219.1

Surely all you need to do is set CLUSTER_DATABASE=FALSE, and start the instance from a non-RAC Oracle home. Then tidy up the cluster registry: use the srvctl utility to remove the RAC database, and add a non-RAC database. All done in ten minutes.

Migrating Non ASM, Non RMAN to New Server with ASM and RMAN - Possible?

We currently have a database ( Oracle 10g R1 ) on a Sun Solaris server that is NOT using ASM or RMAN. The database is about 300GB. We are getting a new server and we want to install Oracle 10g R2 with ASM and RMAN and migrate the database.
I have seen the documentation on migrating non ASM to an ASM server but the methods all use RMAN. Is it possible to migrate to an ASM database without using RMAN? Would datapump import/export work if I created a new database on the new server with all the same tablespaces? Or, do I have to bite the bullet, install RMAN on the old server and do the backup?
Thanks.

If you're not using RMAN that doesn't mean you can't use it to perform a single backup, rman is contained in every oracle RDBMS installation version 10G or higher.
this is only a sample of how to do it
RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '<file_system_path>/%U.DBF';
--first we allocate the channel default channel.
RMAN>RUN
ALLOCATE CHANNEL DEFAULTCHANNEL TYPE DISK;
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
BACKUP DATABASE;
SHUTDOWN
}then once you have it, you can do what you want.
It should also be possible to manually restore the database from the original datafiles but it's better to follow the solution involving RMAN.

Moving spfile from non-asm to asm file system

Hi All
We are migrating non-asm file system to asm file system, we are held up in moving the spfile from non-asm file system to asm file system ...
we tried the below method
Recreate SPFILE on ASM diskgroup
SQL> create pfile='c:\initTEST.ora' from spfile;
File created.
SQL> create spfile='+DGRP2/spfileTEST.ora' from pfile='c:\initTEST.ora';
File created.
after this we started both the running instance and asm instance
but after starting the instance TEST we saw the instance still using spfile of non-asm file system
what is the correct way of moving the spfile from non-asm to asm file system..
Regards
Hariharan.T

You need to perform this first:
First rename the $ORACLE_HOME/dbs/spfileTEST.ora to spfileTEST.ora_old
create initTEST.ora in dbs location with below contents:
Also i recommend you to recreate the spfile in ASM as it might not be in good shape.
When ever you start the oracle instance there is a specific order to find the oracle pfile/spfile
1. O_H/dbs/spfile<SID>.ora
2. O_H/dbs/init<SID>.ora
3. O_H/dbs/spfile.ora
4. O_H/dbs/init.ora
in your case instance always finds spfileTEST.ora in dbs location (non -ASM) and will stop looking further. If you remove it our of the way it will find initTEST.ora which will redirect to spfile present in ASM.
NOTE: As per your earlier update you created spfile in ASM after puttin spfile='+DG...' in the initTEST.ora..
If you start the instance with this SPFILE you will be getting "maxmimum cursors limit exceeded" error.

Migrate entire database to ASM on another server via RMAN minimal downtime

Hi
I was looking for a procedure to migrate non ASM production databases to ASM via RMAN on a separate server with minimal downtime (backup as copy/switch database to copy technique). We have TDPO for tape backup and I normally rman clone test databases between servers but this involves too much downtime for production. The procedure in the ASM Admin Guide (Chapter 8) assumes the databases are on the same server.
Thanks

Tom CullenDear Tom. Why you think you'll have downtime in the production database? The database will be running while the clone will be processing. Check the following link:

Non-asm to asm restore using duplicate

oracle version 11.2.0.2.0
hello guys a quick question, I am trying to restore a database from non-asm to asm. I want to know if the following will work with the duplicate database.
SET NEWNAME for DATAFILE '/clu15/oracle/database/PROD/dbf/NDX_PROD.dbf' to '+DGDEV1DBDATA03/database/DEV/dbf/NDX_PROD.dbf';
SET NEWNAME for DATAFILE '/clu15/oracle/database/PROD/dbf/NDX_PROD_01.dbf' to '+DGDEV1DBDATA03/database/DEV/dbf/NDX_PROD_01.dbf';
SET NEWNAME for DATAFILE '/clu15/oracle/database/PROD/dbf/NDX_PROD_02.dbf' to '+DGDEV1DBDATA03/database/DEV/dbf/NDX_PROD_02.dbf';
SET NEWNAME for DATAFILE '/clu15/oracle/database/PROD/dbf/NDX_PROD_03.dbf' to '+DGDEV1DBDATA03/database/DEV/dbf/NDX_PROD_03.dbf';
Thank You

This above will work.
If you want to use OFA architecture, you can just give
SET NEWNAME for DATAFILE '/clu15/oracle/database/PROD/dbf/NDX_PROD.dbf' to '+DGDEV1DBDATA03';
You can also set the parameter db_file_name_convert and log_file_name_convert.

Migrating a database to ASM.

Hi all,
I have an environment for test purposes running 10.2.0.1.0 database on a Linux CentOS 4 box.
Now what I´m trying to accomplish is migrate this database to ASM.
Some adittional info:
$ ps -ef | grep pmon
oracle 4063 1 0 07:27 ? 00:00:00 ora_pmon_APPS102
502 6659 1 0 07:34 ? 00:00:00 asm_pmon_+ASM
$ lsnrctl status
Services Summary...
Service "+ASM" has 1 instance(s).
Instance "+ASM", status BLOCKED, has 1 handler(s) for this service...
Service "APPS102" has 1 instance(s).
Instance "APPS102", status READY, has 1 handler(s) for this service...
What I´m doing is to log into database through EM 10g console as sys user, then I go to the Administration page from where I can run the ASM migration wizard.
Then, after inform my SYS password and my Host account/Password, I´m facing below error:
Listener refused the connection with the following error: ORA-12528, TNS:listener: all appropriate instances are blocking new connections The Connection descriptor used by the client was: (description=(address=(host=VM_PEGASUS.localdomain)(protocol=tcp)(port=1521))(connect_data=(sid=+ASM)(server=dedicated)))
I´ve already stopped and started the listener and restarted both instances. Did not work, same situation.
Well, any help will be very appreciated.
Thanks,
Marcello M.

Hi,
Please see (How To Use Automatic Shared Memory Management (ASMM) In Oracle10g) Doc ID: Note:295626.1 on Oracle Metalink.
The main goal of this document is to show you how to put in place the ASMM facility introduced with Oracle10g, how to configure it, and also some examples on how to monitor its activity.

Rac to non rac standby file name convert option

Hi,
Rac to non rac with ASM both, please find the below details.
Primary Setup.
diskgroup NAME for all files for both primary and standby +DATA
pmon,unique and service name at standby-rac1, rac2
db version -11.2.0.1
platform - HP -UX
$ ps -ef | grep pmon
oracle11 22329 1 0 22:33:55 ? 0:28 ora_pmon_rac1

oragrid 23522 1 0 Jan 2 ? 1:30 asm_pmon_+ASM2
database and Unique name - RAC, so all files on ASM created under +DATA/RAC
Stanby setup
diskgroup NAME for all files for both primary and standby +DATA
pmon,unique and service name at standby- racdr
$ ps -ef | grep pmon
oracle11 22329 1 0 22:33:55 ? 0:28 ora_pmon_racdr
oragrid 23522 1 0 Jan 2 ? 1:30 asm_pmon_+ASM
database name and unique name is racdr, so all files on ASM created under DATA/racdr when cloned with RMAN from primary backup. (by settling log_file and db_file covert from DATA/RAC to +DATA/racdr )
so now everything ok... but how do we create a new datafiles at primary for the above setting success, ??? and reflect on standby ???.
1.create tablespace tbs size 10g;
2.create tablespace tbs datafile '+/DATA/RAC/test.dbf size 10g; ??
3.create tablespace tbs datafile '+/DATA size 10g;???
4. directories name on asm and specifying on the convert options is case sensitive ???
Thanks in advance...

thats fine john,
log_file and db_file covert from '+DATA/RAC', '+DATA/racdr'
my primary is rac
my standby us racdr
so i mentioned above folders on convert option, so if i created datafile with or without specifying a diskgroup like mentione below, with or without specifying the directory like below
will all create on under '+DATA/racdr' diskgroup ??
create tablespace test DATA size10m; --> not specidying a full path as DATA/RAC' so will it go to DATA/racdr' ?? or creating under DATA ?diskgroup on standby????
Thanks,

Oracle EBS Cloning - RAC to Non-RAC on windows 2008

Kindly note that my Client is currently running Oracle E-Business Suit R12.1.1 + 11.2.0.2 on Windows
Server 2008R2 on RAC + ASM.
I have been requested to perform the Clonning of the Production to Test Enviroment from RAC to non
RAC?
I have gone through the note id Certified RAC Scenarios for E-Business Suite Cloning [ID 783188.1] which
says that Oracle E-Business Suit R12.1.1 is not supported for RAC to RAC or RAC to non RAC Clonning?
Please advise whether the Clonning is possible from RAC to non RAC enviroment on Windows 2008 R2 for
R12.1.1 + 11.2.0.2?
What is the possible risk if I go ahead with the same Oracle non supported Enviroment ?

R12 clone with RMAN auxiliary db.

RMAN cloning from RAC to Non-RAC

Hi Gurus,
I had successfully cloned my DB from RAC to Non-RAC environment via RMAN. Below was the configuration
RAC
- 2 nodes
- 11gR2 (Compatible 11.0.1.6 as per Application Requirement)
- ASM (2 diskgroups DATA and FRA)
- OS RHEL 6.3
Non - RAC
- 1 node
- Stand alone11gR2 (Compatible 11.0.1.6 as per Application Requirement)
- ASM (2 diskgroups DATA and FRA)
- OS RHEL 6.3
My approach was to clone DB and then change SID with nid utility. My understanding was that nid utility will also replace ASM file paths from CRAMPRD to CRAMSIT but that didnt happen.
So issue is when I am checking my file paths on CRAMSIT it still refelect CRAMPRD eg - +DATA1/CRAMPRD. Is there any way to rename this directory paths in ASM so that it should reflect my SID.
Regards,
Nikhil Mehta.

No, NID wouldn't change the ASM paths.
I presume that you did set the ORACLE_SID to CRAMSIT on the non-RAC server before the restore.
What you should have done is to set DB_UNIQUE_NAME='CRAMSIT' (even with DB_NAME='CRAMPRD') on the non-RAC server before the restore. Oracle would have used the DB_UNIQUE_NAME to set the ASM PAth (note that during the restore it would have shown "restoring to +DATA1/CRAMPRD" but would have actually been restoring to "+DATA1/CRAMSIT").
You will now have to use Oracle Support Note
How to rename/move a datafile in the same ASM diskgroup [ID 564993.1]
to rename the paths in ASM.

How to apply archivelogs from 2 node rac to non-rac

Is there any way to apply the archivelogs from 2 node RAC to sinlge node non-rac instance while migrating RAC to non-rac.
Could anyone clarify it?
-Shanlee

There's no "different way".
Each instance in RAC write's to it's own Redo Thread -- so each has it's own set of ArchiveLogs. In the log_archive_format specification %t is the thread identifier.
Oracle needs the ArchiveLogs from both Threads of the 2 node RAC. When you issue a RECOVER DATABASE, it applies them in the correct (interleaved) sequence.
What you have to do is to ensure that the ArchiveLogs of both threads are available on the new server.

Duplicate Database From ASM to ASM

Hi Guys
I am running Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 with RAC on HP-UX using ASM. I have two nodes on cluster now I have a new cluster environment with three nodes using ASM as well.
I want to duplicate my databases from two nodes to three nodes using my backups. I am using rman backups.
How do I begin to do that?
Please help !!!!!!!!!!!!!!
Thanks

Which, as far as I recall, wouldn't make any difference.
Your 'target' is the auxiliary database, which is pointed to by a tns service name.
Provided the backup is accessible on both servers (maybe by using NFS), duplicate database should like a charm.
But then I am already abstracting docs, which is evidently exactly what you want.

Steps to do the R12 on 11.2.0.2 RAC to Non-Rac cloning on Win2008 64bit

Please brief the steps to do the R12 on 11.2.0.2 RAC to Non-Rac cloning on Windows 2008 64-bit.
There is a metalink document but that says it for linux environment but not windows. Please brief the steps if someone has done it on windows.

The steps should be the same for Windows (with minor changes, like you may need to create Oracle service before duplicating the database).
