Oracle control file DO NOT restore in RAC mode !

Dear masters ,

I have a scenario to try backup/restore of tablespaces on my production Oracle servers.

my environment :  Oracle 11g-R2 (OEL 5.5)  -  Netbackup 7.1.0.3

I'm able to backup successfully without any error but when try to restore the instance completely or restore a deleted

tablespace i face errors..

This is important to mention that my procedure is SUCCESSFUL for FS (file system mode) Oracle databases BUT not for

RAC modes.

my procedure :

1- enabling controlfile autoback "on" and configuring channels (RMAN)

2- backing up of control file and tablespaces

3- creating of touch file (NO.RESTRICTION) on Netbackup server

4- startup nomount of instance (SQLPLUS)

5- set DBID (RMAN)

6- typing of RMAN commands on RUN (please refer to attached screenshot)

 

this procedure is OK for FS Oracle DB but I face the error ORA-06172 for RAC databases..

I tried to specify the correct piece handle name by the command :

5> restore controlfile from '/ctrl_xxxxxxxxx';

but the result was unsuccessful...

I will appreciate your comments...

Touch file on master is

Touch file on master is called No.Restrictions  - case sensitive with just N and R in uppercase and 's' at the end.

To troubleshoot, you need the following logs:

On master: bprd (NBU needs to be restarted afted log folder is created).

On RAC node where restore is intiated from: dbclient log (ensure folder has 777 permissions).

Please also share details of backup job - which Client name (NB_ORA_CLIENT) is used for backup?
Which Client name is used for restore request (CLIENT_NAME in bp.conf)?

Please rename logs to reflect process name (e.g. bprd.txt) and post as attachments.

RMAN-06172 no autobackup found

Action: Modify autobackup search criteria or verify the handle

Find below, an example to restore your control file from a backup NetBackup :

1) On your nbu client (connected with your oracle account), display list all files backup available with bplist command:

      [oracle@NBUCLNTORACLE bin]$ /usr/openv/netbackup/bin/bplist -C NBUCLNTORACLE -t 4 -l -R /
      -rw-rw---- oracle asmadmin 20971520 May 06 03:40 /cntrl_1806_1_782538018

2) Shutdown your database and startup nomount:

      [oracle@NBUCLNTORACLE bin]$ sqlplus / as sysdba
      shutdown immediate;
      startup nomount;
      exit

 

3) Restore and copy your control files:

      [oracle@NBUCLNTORACLE bin]$ rman target / nocatalog

      run {
      ALLOCATE CHANNEL CH01 TYPE 'SBT_TAPE';
      SEND 'NB_ORA_SERV=NBU_SRV, NB_ORA_CLIENT=NBUCLNTORACLE';
      restore controlfile to '/tmp/controlfile.ctl' from '/cntrl_1806_1_782538018';
      release channel CH01;
      }

      run {
      ALLOCATE CHANNEL CH01 TYPE 'SBT_TAPE';
      replicate controlfile from '/tmp/controlfile.ctl' ;
      release channel CH01;
      }
      exit

 

4) Mount your database:

      [oracle@NBUCLNTORACLE bin]$ sqlplus / as sysdba
      alter database mount;
      exit

 

 

5) now you can restore your database
