I have a active data guard database which is copy of my production database. can i backup the active database using RMAN? The ADG is a read only and dont know, if RMAN can backup an read only database.
View 4 RepliesWe are using oracle as database in our application. For high availability we have a cluster of multiple nodes and the data is replicated using oracle streams. All the nodes in the cluster are active. We do not have any concept of stand-by.
Now we are planning to use oracle RMAN for backup and recovery. RMAN user's guide doesn't recommend any strategies for such deployments. It mainly focuses on primary/stand-by deployments.
creating the standby database from Active database using RMAN and getting the below issue after i executed the duplicate command.
Version of Database:11g(11.2.0.1.0)
Operating System:Linux 5

provide any work arounds to proceed further in creating the standby database.
I have issue with regards to duplication of an active (prod) database to a test database. This is my sql run by RMAN:
SPOOL MSGLOG to '/proddb/u01/app/dupe.log';
CONNECT target sys/oracle;
CONNECT auxiliary sys/oracle@MWTEST;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
RUN {
duplicate target database to MWTEST from active database;
}
CONFIGURE DEFAULT DEVICE TYPE TO SBT_TAPE;
It stops however in the middle and wouldn't continue. There is still huge space for the test database (3x the current size of prod database).
I have failed to duplicate target db for standby from active db using spfile with the following errors:
RMAN-03009: failure of backup command on prim1 channel at 08/11/2010 05:25:09

The script has successfully created on standby db all controlfiles and also has copied 2 data files DATA01.DBF and DATA02.DBF into the correct location. Then the errors above kicked in and stopped the rman dup process.
I like to duplicate the database DATABASEA to DATABASEB and need to be run in same server. I tried to bounce the listener & databaseb instance multiple times but no lucky.

I'm trying to set up active database duplication between 2 Oracle 11g servers.
Both servers were set up with identical configurations (same directory structures, file systems, SIDs, and sys passwords.) Both oracle instances were created at the time of software installation.
Here is how things are configured:
- Version: Ora11gR2
- Oracle service name: orcl
- File system: ASM
- OS: Windows Server 2008
I've done some research and found several sources giving instructions on how to set up active database duplication (including a blog engry by rajabaskar on this site), but each site seems to have different details.
So, here's what I have so far:
- Set up entries in each TNSNames file... each has an entry 'src' and 'dst' (for source and destination)
- A new listener has been added on the source machine
- on the destination machine, run the 'oradm' to create a new SID. However, is this really necessary? Since the service names are already the same
- I'm also supposed to create a password file on the destination machine using orapwd. Again, is this necessary, if I'm using the same passwords on both machines?
Am I on the right track? Should I have created an actual database on the destination machine or should I have started with just the software installed?
I have oracle 10g installed on my system and name of the database is "ORCL" for which I have schedule the incremental backup everyday. Mentioned below are the steps followed

I am cloning my prod db to test with the rman active clone command. I can successfully clone my DB, but after a few hours or so I see messages in the alert log that I have corrupted blocks in several datafiles. Note, i dont see these messages in my PROD DB therefore I think that DB has no corruption. I have few questions:
1) I was reading tha having tables or indexes set with the NOLOGGING option can cause objects to be unrecoverable. Would this affect my active clone?
2) I know you can either change a DB or tablespace to force logging. Is there a query I can use to determine if the DB is in force logging mode.
ALTER TABLESPACE tablespace_name FORCE LOGGING;
ALTER DATABASE FORCE LOGGING;
3) Lastly how to check as why my clone DB would have corrupted blocks.
Here is the clone command I am using.
rman catalog=rman/rman@proddb target=sys/sys@proddb << EOT
connect auxiliary sys/sys@clonedb

I'm going to backup this un-maintained Oracle 11g server in my office. I'm being told it's never been backed up and extremely critical to our success so tomorrow I'll be performing my 1st backup of the database using RMAN. My question is if I connect to the Oracle 11g database and run the:

RMAN> shutdown immediate
using target database control file instead of recovery catalog
database closed
database dismounted
Oracle instance shut down
BACKUP DATABASET FORMAT �/oracle/u01/app/oracle/backup/%d-%T-%s-%P�;
My question is the above sufficient for a safe full backup? We only have the one single target database called 'cqdb' which houses several schemas. Can you tell me if this is correct? I've shut the database down so it's in a cold state so I don't think I need to configure the FRA (Flash / Fast Recovery Area) but I honestly don't know. This is my 2nd time on a Oracle DBMS.
What about the 'archivelog' files? Do I back those up? Do I need them in case a recovery? Also what about the 'controlfile'? Do I need to back those up as well as the mentioned above?
I have done many duplication before in sinlge instance databases using a backup tool and rman catalog. At the moment i was trying to do a RAC database duplication and facing some issues. For this i was doing a testing on my 1-node RAC. Primary and duplicated database is on the same Host and oracle version is 10.2.0.3. I perfomed following steps:
1.Created a DUPL database using DBCA.
2.Created a pfile using spfile.
3.Dropped all the datafiles, controlfiles and redo log files.
4.Started the database in nomount using pfile.
5.Disable cluster related parameters in pfile.
6.Took a full backup of the MAIN database with archivelog on disk.
6.Duplicate the database and it is done successfully.
7.Shutdown the instance and enabled cluster parameters.
8.Start instance using SRVCTL fails with error CRS-0215: Could not start resource 'ora.DUPL.DUPL1.inst'
But if start the instance using sqlplus it comes up nicely. There is not much information in alert log files.
I want to duplicate a prod database in to a dev db.I am using catalog database to connect to target and auxiliary datbase.I copied all backupsets to the local disk on Dev env in the correct path.For RMAN duplicate ,does the backuppeices need to be present on PROD filesystem as well or just DEV filesystem or both.

My questions are:
Source Server ( target ) : ORACLE_SID : DB11G
AUXILIARY Server (duplicate ): ORACLE_SID : CLONE
1- if backup files (autobackup and backup set)/ Archived Logs are in a different path on the source host (not default FRA Path) then how can I use the DUPLICATE command? BTW, only the flashback logs are in the default location (/u01/app/oracle/fra/flashback). Path: /u01/app/oracle/oradata/DB11G/autobackup and /u01/app/oracle/oradata/DB11G/backupset.
2 - Do I have to add *_CONVERT parameters for different SID as shown below? e.g. : DB_FILE_NAME_CONVERT , LOG_FILE_NAME_CONVERT.

We have a host for restore purposes. We execute monthly or quarterly restore operations to verify that I am able to restore a subset of the data in the given amount of time or to other purposes. I have a automated script to Clone the Database, but to Clone Database we need remove the old database from ASM before start this operation. I want remove only Database files and keep the configuration (such as oratab/network/ocr and so on).
Question: There is a easy way to remove these files without connect on ASM or by using DBCA?

I would like to know how to create recovery catalog database to acheive rman backups as control file will not keep backup info longer. This is for our production database what are the requirements before doing so and what happens to configure retension policy to recovery window.
Initially plan of taking backup to disk and later moving backups to tape device

I have taken the RMAN Full database backup through the following command.My database is in no archivelog mode.
AT RMAN prompt
Shutdown immediate;
Startup mount;
run
{
allocate channel c01 device type disk format 'd:
man_bkp est_%U';
allocate channel c02 device type disk format 'd:
man_bkp est_%U';
backup full database tag 'full_bkup_test_081111';
backup current controlfile;
backup spfile;
release channel c01;
release channel c02;
}
Now i have deleted my all controlfile and spfile/Pfile from the database.So how can i recover my SPfile and controlfile? i do not have autobackup on of SPfile/Controlfile.
