Backup Oracle Database Using RMAN Utility?
Feb 13, 2012
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:
[oracle@db1 ~]$ rman target=/
Recovery Manager: Release 11.2.0.1.0 - Production on Mon Feb 13 13:18:05 2012
connected to target database: CQDB (DBID=1854033249)
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 need to login remote DB writing a shell script where our DB is on a separate node, i have to test the script only with
SCHEMA USERNAME
PASSWORD
HOSTNAME
PORT NO
SID/SERVICE NAME
these details. May be am wrong to ask this question but i need to login and check the requirement. Is there any other anyway to login without sqlplus utility?

We are running a 5Tb database backup which takes really a long time to backup and impacts the performance in general during the backup. We got a DataGaurd database in place which we want to utilize to run the RMAN backup on to avoid performance impacts and just use DG database for backup and DR purposes. My Question is if we run the backups on DataGaurd Database, How would a RMAN DG database backup would clear the archive logs from Primary production and from DataGaurd Database during the backup process?

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 would like to duplicate to the different server Oracle Database with RMAN. I've configured flash recovery area for Oracle Database.
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.
DB11G.__java_pool_size=4194304
DB11G.__large_pool_size=4194304
DB11G.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment
DB11G.__pga_aggregate_target=155189248

Oracle Database 11.2.0.3

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 was handed a folder that consists of all the files (Datafiles, controlfiles,spfiles, backupsets etc) for a database. The SID is Oracle.
So now I have two options:
1. Attach the Datafiles
2. Restoring the Database with the Backupsets.
Option 1:I tried with working with the control files but didnt get anywhere because I did not understand how to attach the datafiles (I tried modifying the control file, to no avail).
I tried replacing the spfiles and pfile then copying the datafiles (replacing the existing ones)...but I could not create the control file as well...
Option 2:I do not know how to make RMAN see the backupsets of the Old database; despite they are in the same location as those of the new database.
