RAC to RAC CLONE FROM RMAN Cold Backup

Hi All,
I need your kind assistance in Cloning my Oracle RAC 11.2.0.2 Environment to remote host. Following is Disk layout
DGVOT (ASM Disk group holding OCR and Voting Disk)
DGDATA (ASM Disk Group Holding Data FIles)
DGFRA (ASM Disk Group Holding Fast Recovery FIles)
Remote Host is on different location so cannot use RMAN duplicate with auxiliary channel.
Have luxury of downtime so I want to take RMAN Consistent( Cold Backup)
SAME Disk layout is available to remote hosts.
11.2.0.2 CLusterware (GI) Plus the oracle binaries are already installed.
Can any body tell me the steps to
1) How to take cold backup to disk so that I can tar and copy to remote host
2) clone the database on remote host
3) How i will add the database listener and other resources of this databasee to clusterware.
actually this is my first RAC clone so i am not much aware of detail steps.
I have gone though many metalink notes but no one is matching with my requirements. your expert advice will help me a lot
Regards,

Hi
1) How to take cold backup to disk so that I can tar and copy to remote host.
Use Rman for cold backupIn mount stage execute
RMAN>backup database plus archivelog format '<disk_path>/dbp%U';
RMAN> backup current controlfile format '<disk_path>/ctl%U';
Copy thse backup sets to remote host
2) clone the database on remote host
Create Similar ASM Disk groups as on source
create pfile/spifile, startup instance in nomount mode
catalog backup set
RMAN> catalog start with '<backup_set location>';
Restore controlfile
RMAN>restore controlfile;
RMAN> restore database;
RMAN> recover database;
On successfull recovery
RMAN>sql 'alter database open';
3) How i will add the database listener and other resources of this databasee to clusterware.
User srvctl to add resources
Usage: srvctl <command> <object> [<options>]
commands: enable|disable|start|stop|relocate|status|add|remove|modify|getenv|setenv|unsetenv|config|convert|upgrade
objects: database|instance|service|nodeapps|vip|network|asm|diskgroup|listener|srvpool|server|scan|scan_listener|oc4j|home|filesystem|gns|cvu
For detailed help on each command and object and its options use:
srvctl <command> -h or
srvctl <command> <object> -h

Non RAC to RAC clonning

Hi all.
I have installed EBS in OEL5 OS, and database 10g R2 pachset 3.I have database and apps server in the same machine.
Is it possible using rapid clone to go to RAC?
Is there any doc or a road map for doing this?
Thanks in advance
Soni

Soni,
Use Rapid Clone. For more details, please refer to the following document.

RAC clone from PROD to DEV

HI,
I wanted to know what would be the steps to clone a RAC database instance to another RAC database instance, in this case PROD RAC to DEV RAC? Are there any docs out there?
Thanks in advance

The steps are no different to clone a single instance db.
With Oracle 11g there are 2 nice new feature in Enterprise Edition which makes creation and maintaining of a development system faster and easier:
=> Use RMAN Duplicate to clone a DB without the need of a backup location
=> Use DataGuard Snapshot Standby. This allows you to open the Standby DB for development (e.g. over the day) and resync it with production (e.g. at night). This reduces the need to do the cloning every time again.
See: http://www.oracle.com/technology/deploy/availability/pdf/twp_dataguard_11gr1.pdf
Regarding Pre Oracle 11:
Cloning of the DB can also be done via. RMAN duplicate (see documentation), but you will need additional space to store the backup.
See Oracle® Database Backup and Recovery Advanced User's Guide 10g Release 2 (10.2) under RMAN Duplicate.
Furthermore in GridControl there is a nice GUI to do this.
Hope thats helps a little

Standby,RAC,Clone DB

Hiiii All,
Can any body tell me what's the difference between Standby DB,Real Application Clusters and Clone DB???????????

Hi.
Standby DB is a HA solution where one database can have up to nine standby databases. The master database shuffles redo to the standby database where data is applied and the standby database is kept up to date. In case of a problem with the master, the standby can take over. The most importent issue here, regarding your question is that we have to physical databases.
RAC is simply two or more instances that shares a physical database. The database is accessible throug two or more instances which has it own set og SGA/PGA and backgroundprocesses. Using services with RAC, enables you to implement active-active or active-passive. Independent of what you choose, the physical storage is the hotspot, and off course a single point of failure.
Clone DB is simply to take all datafiles from one database, move them to another server or another location and open the database. I think RMAN can clone the database for you or you can clone any database yourself with copy command.
Hopes this clarifies some.
Anyone else??

Finding the order of archive logs in RAC to NON-RAC manual cloning

Hi,
I am in the process of automating a RAC to NON-RAC clone using traditional method [ not using RMAN ].
Here are the steps:
On Source:
Record the sequence number and thread of the instance
put the database in begin backup mode
copy the files
disable the backup mode
record the sequence number and thread of the instance
prepare the order of the archive logs which will be needed for recovery ==> Here is where I need help
On Target:
Restore the backup
Issue recovery using the order of archive logs identified ==> Failing as order is not correct.
I am finding the archive logs based on FIRST_TIME# and preparing the order which is not correct. I think i should be using SCN but not sure what should be the criteria.
Could you please let me know on what basis we can find the order of the archive logs which will be asked during the recovery ?
Your quick response is appreciated. Thanks in advance for your help.
Thanks
Suneel

Yes, When we execute recover database using backup controlfile until cancel, will prompt for the redo log sequences.
But as i mentioned before, I am trying script everything and cannot manually enter the sequence numbers required. I need to know the archives and thread it is going to ask [ in what order as well ] so that recovery command can be scripted in shell.
Please let me know if there is a away to find the order of archive logs which needs to be applied to recover [ if this is a NON-RAC, we can simply go with the sequence numbers but since it is a RAC, i should know the thread number as well ].
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 ?

Hi
It is mandatory to be certified for RAC clones.

Oracle Clusterware clone

Hi,
I want to know, if during oracle clusterware clone, do we need to copy OCR and voting disk also to target node along with the CRS & Oracle binaries? I checked the oracle documentation and they have not mentioned it anywhere. If we should not copy the OCR and voting disks then how these files will get created on target node.
Thanks,
Prasad

RAC - NON RAC ebiz clone

The title says it all... We are running eBusiness Suite 11.5.10.2 in Production on RAC 10gR2 (red hat linux, split application and database tiers). Is there a tried, tested and reliable way to clone from the Production RAC environment to a development environment which is non RAC?
Thanks in advance
IH

That scenario is covered in the rapid clone doc:
Cloning Oracle Applications Release 11i with Rapid Clone
http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=230672.1
Note: To clone from RAC to non-RAC, follow the same above steps but copy the master ORACLE_HOME to one target node only, and answer "No" to the question "Target instance is a Real Application Cluster (RAC) instance (y/n)", when prompted by adcfgclone.pl.

How do we clone a database from RAC/ASM to RAC/ASM?

Is there a best practice or recommended recipe for cloning from a RAC/ASM instance to another RAC/ASM instance? We've done single instance cloning in the past with RMAN and it looks like grid control does something similar -- until we try to clone from one Exadata cluster to another. Surely this is now a common procedure...?
much thanks,
Gary

Hi,
I would not use cloning with 11.2. anymore.
Though this will work (you have to take care of copying some more stuff though, like the gpnp profile), simply using the "addnode.sh" which works in silent mode in 11.2. is a lot easier.
Re: Any issues to add 3rd node to 11gr2 grid with 11.2.0.2 and 10.2.0.4 homes?

How to clone a 2-node ASM RAC db to a 3-node ASM RAC db by RMAN?

We need to clone a 2-node ASM RAC db to a 3-node ASM RAC db by RMAN. I would think this will be about the same as a regular single db procedure by RMAN mostly. However, in 3 node RAC, there will be additional instance thread in redo (thread 1,2, and 3). Questions will be
1. Should I use CRSCTL to add new instance (3rd)? -- I guess yes
2. Should I create additional online redo group for thread 3? -- I guess yes
3. Should I create addition undo tablespace? -- I guess yes
Can any body provide a procedure of cloning the DB?
Thanks!

Not just easy as next, next, next
version depenedencies and etc.
