RMAN :: How To Remove Database Files And Backup From ASM
Oct 19, 2012
Oracle Database 11.2.0.3
OEL 5.7
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 had a production db with archive logging enabled
SQL> select name,status
2 from v$archived_log;
NAME STATUS
---------------------------------------- -
D:ORACLEARCHIVE_ORCL11_13.DBF A
D:ORACLEARCHIVE_ORCL11_14.DBF A
D:ORACLEARCHIVE_ORCL11_15.DBF A
[code]...
So i need to restore archivelogs by using sequence
RMAN>RESTORE ARCHIVELOG FROM SEQUENCE 20 UNTIL SEQUENCE 28;
So the restore is completed successfully
So its very hard to monitor archivelog files
i feel i should have included all archivelog files while taking RMAN backup
RMAN >backup database plus archivelog all delete input;
but the problem is my RMAN backup is already 360GB in size and it takes 4-5 hrs to complete .so i need to schedule RMAN backup at one time (e.g sunday) ,delete the archivelog files older than sundayand now schedule the archivelog backup at another day (e.g wed &sat)
my question is where i have to change my script to backup all avaialbe archivelog files if old archivelog files are deleted at os level?
RMAN> run {
2> allocate channel c1 type disk;
3> sql 'alter system archive log current';
4> backup archivelog all format 'D:oracleackuplog_t%t_s%s_p%p' delete input;
5> release channel c1;
6> }

I want to remove matching dbid's from the rman catalog without compromising te integrity of the catalog. I do however know a single way of removing them and its using the dbid and db_key which in my case are not not unique. The funny thing is they've running normally for a year now.

Accidentally without checking the channel allocation I have given the backup archivelog from sequence until sequence with delete input. This backup piece went to the disk but it should go to Tape.I know that we can catalog this backup piece but I want to move this backup files in disk to Tape using RMAN. Is there anyway or I have to lie with Backup team or OS team for this file movement?

I took backup of Datafiles , archivelog files and controlfile through RMAN. Now, i want 3 backup file will created as a output of RMAN operation. It would be :
1 backupfile for all the datafiles
1 backupfile for all the archivelog files
1 backupfile for controlfile.
It have to be regardlessly whatevr my DB size is. It it possible to do so. How i can can write rman script to accomplish the task.

I would like to know that if I enable backup Optimization on then incremental full backup skip any files which was earlier backup? Because we may know that backup Optimization on ensure skip those files which are already taken backup.

We have a nightly rman backup that was complete and clean.The backup contains a Data File, Control File and a backup Archive Log file.The database server crashed with all the subsequent archive logs lost.
We are trying to recover from the three backup files.We are bumping into the backup piece missing as all the archive logs are done. how to restore with the exising backup files. the lost archive logs are probably salvageable.

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 am an absolute neophyte at this. I'm fairly good at SQL, but have not administrated a database before.
I am trying to take a backup from our production database and restore it to a fresh install of Oracle 10.2 on a Windows 2003 server using RMAN - but I am not getting very far. Software versions are all the same. I have access to the manuals, but it seems like every link I follow adds more questions than it answers.
I have gone through the wizard and set up oracle on the new box - that all seemed to go smoothly. In order for this to work, do I need to set up the database with the same DBID as the one in the backup files? Or is there a way to import the data from the backup and have it build the database from those files?
I'm not sure I'm even asking the right questions. Do any of y'all know of a tutorial that would walk me through this process step by step?

I have the following situation: a customer sent me a group of files, that he said to be a "backup" of an old database, that is no longer online (he doesn´t use our software anymore). However, he needs to recover the data in this database. The person at the company who generate these files doesn´t work there anymore, so we don´t have any of the following information:
- Database version, connection details, service names, user names neither tablespace names.
We were just told that these files were recorded in a DVD, and is que only source remaining.
The files he sent are the following:
ctrlcf_satp_01.ctl
ctrlcf_satp_02.ctl
ctrlcf_satp_03.ctl
daddf_satp_dad_01.dbf
[code]......
Is there a way to access this data? Or can I tell our costumer that your data is lost forever..

How one should know whether RMAN is using target database control file or using separate catalog database. Also what one should do if he dont have catalog users credentials.

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 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
