Oracle RAC cold backup to a non-RAC DB ...

We are running a Windows 2003 (SP2) box with Oracle 10g release 2 (10.2.0.3). This was originally configured to be a RAC server (having node1 and node2) but we lost node 2 some how.
Now we want to create a fresh DB (no RAC just plain DB installation having the same OS and DB version as given above on the dead node 2) and copy the DB from node1 to node2 with cold backup method.
My question: will the cold back work in this scenario or we will have to do a EXPDP/IMP thing. I am not too familiar with impdp/expdp so thats is why the plan is to copy the cold backup and bring up the instance.
Is this possible?

Thanks.
So, doing the cold backup is:
take CONTROL FILES, DATA FILES and REDO LOGFILES copy. Is that it.
Would someone have a document which provides a script to know what files backup is to be taken and what is thier location in the file system. I know this is a basic question but i am just being careful here.
thanks,

Rman cold backup for oracle rac

Hi experts;
I want to create a cold backup for an oracle 10g rac DB.
It has 2 nodes, it's not in archive log, this will be the next step.
But now, I want to backup before to proceed.
My doubts are:
I need to shutdown the both nodes?
If yes:
I need to startup nomount just in one node?
If there any document with this specifics steps?
Thanks for your help.
Al

Cold backups are done with the DB completely shut down.
For RAC the data files are used by all nodes in the cluster.
You need to shut down all instances in the RAC.
Then use your OS utilities or RMAN to do the backup.

Create new db from RAC cold backup

Hi Team
i need to copy cold database from one server to another server . and build an new rac database out of that cold backup .. i have done it for singel node instance . but do you know if i have to do something special for RAC instance .. or simply below mention steps are enough to build RAC database out of cold backup
oracle version is 10.2.0.1
1. install software and clusterware on new set of machine
2. copy cold backup on that set of machine
3.copy spfile and controlfile
4.open the database up with controlfile,spfile and dbf files
now i am not sure on one thing if i have to do something special for RAC DB or its like single instance.
please let me know if this is not clear or you need more info on that

Restore from cold backup (rac server)

Hi All,
Oracle version : 10g
OS : SunOS dixie1 5.10 Generic_118855-36 i86pc i386 i86pc
I am having cold backup of RAC server (2 nodes), I want to restore from cold backup.
The problem is that : when i performed the cold backup using rman at that time Oracle was having 3 ASM diskgroups.But unforunately that disk is no more in use due to some fault.
Now my question is how can i restore from the cold backup as when i'll restore from the cold backup this will ask for the same ASM diskgroups.Even more if i creates the same diskgroup with the same name and same configuration then my doubt is that rman will allow me to restore the same from the cold backup as ASM disk header changed now ?
Thanks,
Vipin

Yes.You can do these and restore/recover your database.First you need startup your ASM instance then create your ASM disk groups and do following:
1.Edit pfile and change controlfile location to diskgroup(Consder that +dgr1)
2.Restore controlfile to this disk group using backup of controlfiles(you say that is cold backup)
rman target /
/*Instance need starting up from pfile*/
startup nomount ;
/*then restore controlfile,give full path of controlfile from coldbackup*/
restore controlfile from 'coldbackup_location\coltrolfile';
alter database mount;
catalog start with 'coldbackup_location';
backup as copy database format '+dgr1';
switch database to copy;
alter database open;

Cold backup in RAC envornment.

Hi,
Oracle 10g (10.2.0.1.0) With rac
OS : HP-UX 11i
I want to know in RAC enviornment which files including (datafiles,controlfiles,logfiles,spfile,password file,listner.ora,tnsnames.ora,sqlnet.ora) should be included in cold backup.
Are there any cluster files that should be included in backup?
Thanks.

Actually, I deliberately chose to concentrate on the first and main part of the original question. You obviously think the line about 'Are there any cluster files that should be included' is worth concentrating on. Both approaches are valid, I think, but your choice doesn't mean I "forgot" anything.
If, for example, I was to point out the voting disk on Windows is backed up with ocopy instead of dd, does that mean you "forgot" that fact? If I mention that there are five retained autobackups of the OCR, does the fact that you didn't mention that number mean you "forgot" it? Does the fact that I have just neglected to mention that the five retained backups are from 4, 8 and 12 hours ago plus 1 day and 1 week ago mean that I forgot those details?
No: we all choose to structure and filter our comments as we see fit. One can add to and enhance someone else's comments without presuming to know the mind and intent of their author and passing judgement accordingly.
For the record, I chose not to mention voting disks and OCR backups because the voting disk never needs backing up, but can be simply re-created and the OCR as you mention is automatically backed up frequently and a simple OS backup, suitably configured, can make sure those autobackup files are transferred somewhere safe (i.e., onto tape) without me having to schedule additional backups using ocrconfig.
I accept your preferences will be different, but those happen to be mine.

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

/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@vvsms log /home/oracle/log_rman/vvsms.log appendThis line can be your problem.
As this database is a RAC and your are using a service with load balance "vvsms" and "/home/oracle/backup/vvsms" is not a shared location. RMAN is starting a session on Other node where "/home/oracle/backup/vvsms" does not exists.
Try change it :
/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@vvsms log /home/oracle/log_rman/vvsms.log appendTo this (using Easy Connect Method):
/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@localhost:1521/VVSMS log /home/oracle/log_rman/vvsms.log appendWhere:
localhost: your local node
VVSMS : is the service of database
Also check if "/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/sqlnet.ora" have configured the line "NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)"
P.S : When RMAN start a session it show where is logged, check on logs what instance RMAN was logged.

Oracle RAC 10g on Solaris 10 in a non-global zone

I need to run Oracle RAC 10g on Solaris 10 in a non-global zone as I must cap the CPUs used for Oracle licensing limitations. My question is a simple one, but one for which I'm getting conflicting information depending upon whom I ask.
If I want to run RAC in a non-global zone on two nodes, does this require the use of Solaris Cluster?
I know there are good reasons to use Solaris Cluster, but the company for which I work cannot afford the additional expense of Solaris Cluster at this time. Is it possible to run Oracle RAC 10g in a capped container without Solaris Cluster or is Solaris Cluster absolutely required?
Thanks in advance for any insight you can provide.

AFAIK, Oracle 10g RAC is not supported in solaris containers.
It is however supported in Solaris zone clusters...in order to use it, you would have to use Sun Cluster 3.2 (iinm).

RMAN backup in ORACLE RAC database

Hi there,
We are using RMAN backup strategy for taking backups from one node(eg.node1).Database is RAC database, version 9.2.3. and OS is Solaris 5.10.
this is the configuration which we use, as follows:
Connecting to Prod.Database using catalog database.
rman catalog=rman/rman@CATDB target=sys/oracle@PRODDB(node 2).
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 30;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/rmanback/_%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 5;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/rmanback/CMWPROD_%s.bak';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK CONNECT 'SYS/oracle@PRODDB(node2)';
CONFIGURE MAXSETSIZE TO 7 G;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/9.2.3/dbs/snapcf_CMWPROD1.f';
As the above config shows RMAN is connecting to PROD DB (node 2). But we need to take backups (datafiles and as well as archive logs) from two nodes (i.e from node 1 and as well as node 2).
Is there any possibility for taking backups from two nodes?
Thanks,
Balu.

Q: Oracle RAC backup

Hi Guys,
I'm new in RAC. I have a Oracle RAC database with 2 nodes. I want to know if it is good/appropriate to backup the 2 nodes instead of 1. Since I believe they both use the same database.
Thanks,
Benjo

>
Currently we are backing up two nodes of the Oracle RAC individually. What is on my mind is to backup only 1 node and that is all.
>
It seems to me that you should first get a clear understanding of what to backup . There is only one database to backup in a RAC, regardless of the number of nodes. If you are happy to connect with RMAN to one node and take a backup there, everything is fine. There is no need to connect to the other node and do the same there.
That is, if you have placed the archivelogs on the shared storage. This is a best practice. If they are on node-local devices, there is actually something node specific to backup. Else there is not.
Kind regards

How to backup oracle RAC filesystem

Hello,
May anyone in this community might help to answer on my inquiry on how to backup oracle RAC filesystem. There are many backup features available out there i.e: RMAN, hotbackup etc but the way the backup is working is RMAN will backup and stored the db file in the filesystem. I presume the filesystem also need to be backed up in order to avoid the filesystem corrupted etc
Regards

Hi,
Always welcome ..
when you want to take backup of all the database components of RAC, that's why i advised you to include the all commands in your backup strategy, so that in any case your any components doesn't work , you can restore the particular one .
One thing you can do , you are running your RAC environment on Vsphere , in that case , create a backup plan with the client and your IT team to take backup of whole environment by creating snapshot of Vsphere along with backup plan mentioned by me in above reply , so in worst scenario your whole environment can be restored .
I have seen that if RAC environment is running on VMware , then its best to take snapshot of whole machine which should be defined in backup policy apart from normal backup of database.
Thanks

RMAN backup and Oracle RAC

Hello,
I am newbie with Oracle RAC 11g.
So, I do the following steps to configure RMAN to back up the Oracle RAC:
- Create a tablespace to RMAN User;
- Create the user rman;
- Connect to catalog (the databsae RAC itself);
- Register the database;
- Create the "complete_backup" script on catalog.
So, when I enter on Enterprise Manager, I can see
the "Availability" tab and the "Recovery Catalog Settings" link.
I setup the user rman that I've created with the host RAC1.
Is this really necessary on EM? The "Backup Setting" on EM
is equals to rman (database user) catalog?
When I go to "Schedule backup", I want to use the "complete_backup" script
that I've created. What the best way to schedule this script
to run each sunday, for example?
Thank you.

Hi,
To perfom a test you can create a new single database (RCVCAT) in one of the hosts that you have.
Create a database without any option with and use minimum of memory (don't use memory_target) set pga (50M) and sga(400M).
Create a user RMAN; with Grant connect,resource,recovery_catalog_owner.
Tablespace RCVCAT;
With RMAN connect on RCVCAT and create your catalog.

Problems doing backup in Oracle RAC

I am working with ORacle RAC, version 10G. That thing about Oracle RAC is completely new for me. There is three databases, I'm doing backups using OEM, but here is the problem. We have defined the directory /backup in both nodes. The problem that I have is when I do the backup it's done in one node, example, today I do the backup, it's done in NODE1/backup. The next time I'm going to do a new backup by any reason the aplication (OEM) is pointing to the NODE2/backup. So here is the problem, if I need to use the first backup, I can't use it, because OEM is pointing to NODE2 instead on NODE1. My question is, how can I set the node, with OEM where I want to do backup or retrieve a prevoius backup?
Thanks for your help.

Thanks a lot forn your suggestion, but I think I should give you more details about my doubt.
The following are the steps for a backup with Oracle Enterprise Manager
steps
Thru OEM
Maintenance
BACKUP/RECOVERY
Schedule Backup
Archive Logs (Whole Database, etc.)
Then here I click override current settings, by the way, the default is spaces, so I type /backup, but problem is that directory exist in both node, Node1 and Node2, I'm working with oracle 10G, RAC, in a operating system AIX 5.3.
Then I click Compressed Backup Set, and that's all what I'm doing. But the problem is, sometimes the backup is done in Node1 and other in Node2. And if I need to restore from any previous backup that was done in NODE2, and the application (OEM) is pointing to NODE1, and can not use that previous backup. So, my question is how can I control this, using OEM. I mean, How can I set the Node, to identify in which node the backup will be done, or in which node is the backup I'm going to restore.
Thanks again

Oracle Rac as part of OSDB Migration

Hello Gurus,
We are going ahead with OSDB Migration from HP-UX to Linux. Here as HA solution, we plan to implement Oracle RAC on the target systems. Where as the current environment is non RAC.
As part of OSDB migration we are not confident in doing it on Oracle RAC. Documentation for Oracle RAC on SAP explains first go for single instance installation on oracle cluster filesystem and implement RAC as a high availability solution with SAP Enqueue Replication service. Then do the backup and restore process from non RAC system to RAC.
But in our scenario we should go for EXPORT/ IMPORT process.
Please guide us in going ahead with the right approach.

This is not an antagonism, you can do a single instance installation by doing the import. Basically an "import" is a new installation with the export you've done before.
