I have taken the RMAN Full database backup through the following command.
My database is in no archivelog mode.

Now i have deleted my all controlfile and spfile/Pfile from the database. So how can i recover my SP file and control file? i do not have autobackup on of SPfile / Controlfile.
We are upgrading from oracle 9.2.0.8 to 11g r2, and both are Standard Edition database. The database is part of a product that runs on a customer site, and won't get bigger than 50 GB. It runs in archive mode, and our backup script does a hot backup every night, plus copying the archive logs, redos, controlfiles, etc. We save 2 entire backups - from the last night plus the night before last. Then there's a tape backup that saves the backed-up files to an off-server location.
This architecture has allowed us to recover our customer's data from many odd occurrences at customer sites (power loss during a hot backup, corrupt controlfiles/datafiles/archivelogs). My question is, given that we are running the Standard Edition database, which doesn't have most of the useful RMAN features, is it worth it to switch to RMAN?
I took an Oracle Backup and Recovery class and posed this question to the instructor, and the response was, it would be better to use RMAN over a manual user backup script. Our backup script is pretty battle-hardened - is that the best reason?
,I am new to Oracle database administration i am working on a 24*7 tool .the tool will work as a non stop.this is a standalone tool.there wont be any one who will be taking care of the database.I need to design a backup statergyNeed to take backups on timly basis.Since the database can't be go offline cold backup's can not be useenhot backup needs to implemented.what are steps needs to do for hot backup.Is there are some pre defined scripts to run the backup.
The customer wants the RMAN recovery catalog database to be highly available so that none of the RMAN database backup jobs are impacted at the time of taking the database backups. There are are 200+ databases running on OEL, RHEL and Windows. So we planned to host the recovery catalog database on Oracle Active DataGuard 11.2.0.1 Enterprise Edition on RedHat EL 5.8 version on two physical servers.
The Primary Instance will be in one server in the Primary DC and the Standby Instance will be on another server in another DC. Also all the database datafiles are hosted in ASM Diskgroups on SAN (DATA, FRA, REDO, ARCH diskgroups). Are there any specific RPM/patch/OS user custom/specific settings or configurations needed..?
I run DLY cold backups including controlfile & archivelogs and keep 3 gens of backups and archivelogs to 3 days also. What is the correct procedure to restore back to an old cold backup. Database is backed up Mon,Tue,Wed on Thur we require to bring database back to Tuesday DLY security.
I have tried: startup mount restore database from tag 'DLYTUE' recover database
( this just rolls forward on all archive logs once it restores datafiles, not getting to point to alter database open resetlogs.)
Next tried to :
recover database archivelog tag 'DLYTUE' ( same outcome )
What is the correct rman procedure including should I remove old archive logs from working OS directory ? Also need to know once I restore back and open database to TUE security how do you tidy up the archive logs and dumps which are no longer require i.e. : weds..
I have read about using the set until time option but how to I get absolute time from when cold backup completed if this is the correct procedure.
I am using RMAN with a recovery catalog option on a separate Database. My question is
When we use catalog does RMAN keep the information in Control file of the Target Database as well or only in recovery catalog? I am asking this in case We lost the database which contains the recovery catalog what to do?
While connecting to target database from stand database. I am getting below error.

Backup-Based Duplication Without a Target and a Recovery Catalog Connection?
I have a doubt regarding the process the RMAN follows for restore and recovery of the database.
My Level 0 full backup completes on Saturdays at around 11 am after taking 8 hours (It starts at 3am).On Sunday, I ask RMAN to restore (on a different box) till Saturday 11:30 am.Then, after the restore is successful, I recover it till 11:45 am.
The recovery also goes fine and Iam able to clone to test box.
Till what time is the database restored? I assume its till 11 am since the L0 backup finishes at 11 am though I have asked it to restore till 11:30 am
During the recovery, ONLY the archives generated between Saturday 3 am and till the time i asked for recovery (Saturday 11:45 am ) are required. But, checking the recovery log file, i was surprised to see that RMAN has restored archive files starting from Friday 9:30 pm (Much before the time the Level 0 backup even started).
I am making incremental backups via RMAN, the backups are staying at disk. And the infrastructure team will copy this files backups to tape. And they want delete the files that will staying in disk via RMAN. Until now it's ok.
But and if I need of backups that stay on tape, it's possible make a recovery of deleted files by rman.
I was trying to backup my database via RMAN and I had deleted a datafile from the database while it was still in open mode.Since I can't return back to mount stage again,I tried to bring the tablespace pertaining to that datafile offline and then restore backup of the tablespace but it's falshing error during recovery.
When I try to restore entire database,it is not even able to restore.
1. My RAC (old RAC) had got a failures from one node, then there was only one existing node now.
2. I configured a RAC (new RAC) on 2 other servers, both of them (old-RAC and new-RAC) has got same OS version, platform and Oracle version release.
3. I took a full backup yesterday plus archivelog in the node of old-Rac, configure NFS in new-Rac to make the backup within remote-share NFS.
The only problem still now that I've restore/recovery/duplicated single instance, not Rac. So, may you guide me to do it?
Information:
Old-Rac & New-Rac: + Cluster 11g: CFS + Database: 2 nodes with same instance name (cbs1-cbs2) + Location for CRS_HOME and ORACLE_HOME: Same to be. + Location of archivelog: Same to be (+ARCHIVE)
I have the RMAN full database backup of oracle 10g (10.2.0.3) on Sun Solaris OS which i want to restore on oracle 11g (11.2.0.3) on Linux OS. The backup pieces was transferred to oracle 11g server manually in binary mode.
the backup is taken in above format. I know the ORACLE_SID and dbid of the database from which the backup has been taken. whenever i tried the following command

what is %N determines in Oracle RMAN HOT Backup. In some documentation it says it gives you backup with respect to tablespace. Is it a version specific ..bcos when tried in above version it failed....
We are trying to restore a database on the different server using RAM incremental level 0 and 1 backups. We have weekly Incremental level 0 backups along with incremental backups on daily basis. During recovery of Incremental level 0 backup, RMAN is expecting/looking for Incremental Level 0 backup of prior week as well. Is this the usual process for RMAN to look for prior level 0 backup though we need to restore from the current level 0 backup and roll forward by a week with subsequent Level 1 backup.?
We intend to restore from the Level 0 of 1/16 and roll forward with daily incrementals till 1/22. RMAN is expecting level 0 backupsets from 1/9 backup as well and keep failing since those backups are not available. quick inputs since we are in middle of recovery and trying to resolve if this is even doable.
I have problem on using "delete obsolete" in RMAN.
First, let describe my backup configuration.
1. Full backup every Monday (17-Oct, 10-Oct, 3-Oct, 26-Sep) 2. Incremental backup for other days 3. Enable autobackup of control file 4. Backup archive log every day 5. RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS 6. Execute "Delete obsolete" every day 7. control file is used instead of catalog
The results observed: 1. Backup of control files older than 30 days will be deleted 2. Backup of archive log files older than 30 days will be deleted. 3. Backup of datafiles older than ~14 days but before 30 days are also DELETED.
In my example, the backup of datafiles created at 26-Sep is deleted at 16-Oct.
I tried "restore database validate until time "sysdate-22"" at 17-Oct. And RMAN reported "datafile xx will be created automatically during restore operation". It seems that RMAN failed to do restoration up to 22 days ago. The retention policy I set seems not effective on datafile backups.
I checked view v$backup_set and the "Keep" is "No" and "Keep until" is empty.
The only thing I can think of, is the settings of "CONTROL_FILE_RECORD_KEEP_TIME". It is marked "7" in the Oracle, which is less than the retention. But I suppose this only causes the backup not deleted, but NOT be deleted earlier.
I have to test a hot rman backup on testing environment and I have some doubts.
STAGE Server 1 production database (linux) backup folder on cifs share windows server Server 2 testing database (linux)
First I installed linux on same network, I gave it access to cifs backup resource, then I installed the same database version than production environment, then I create a typical database with only same database production name. Also the Linux partitions between linux servers are different.
What protocol is used by RMAN to communicate with the server used for backing up/restoring data? Would it be possible to intercept and modify the calls made by RMAN?
Background: I am developing a proxy that backs up an oracle database to a different store
