Someone(a non DBA) removed the only sysaux datafile from the server using the rm command Obviously, the DB is still up and none of the schemas in the database have their objects right now.
This is not a critical database as you can see when I say that I have NO backup whatsoever. Even though I have the option of deleting and recreating the database, i want to know if I can avoid doing that.
Creating a file on the server with the same name OR creating a new datafile for the tablespace OR recreate the sysaux tablespace ?But how to do any of these? What else should be done ?
Oracle 11G...After creating a new datafile, it was accidentally deleted at OS level (AIX).Because it was new there are no backups of it.Now tablespace thinks there are 3 datafiles in it, but one of them is missing.
Is it possible to recreate an empty data file on-the-fly?It has let me set the datafile to offline, but wouldnt let me do anything else.
Now my backups are failing as it recognises :"the status of database file is RECOVER".
I have 2 seperate rman backup one backup is of only datafile ,spfile and controlfile which i am able to restore and recover without any problem say bkp1 taken at 10 am
other set of backup is of only archive log files of same day but later time than datafile backup say bkp2 taken at 8pm...if i restore and recover bkp1 and try to restore bkp2 it gives error datafile exist (possibly due to fact both backup have control file)
if i just restore bkp1 and try to restore bkp2 so that i can do one recover at time it gives error datafile permission issue (possibly due to fact both backup have control file)
I want to restore database upto 8pm time how can i use both bkp1 and bkp2 to do it(restore datafiles and apply all archive logs on it)
how i can change backup datafile name into its original file name,bcoz at time backup datafile name is different and how i can change that name into its original datafile name so i apply recovery command in user managaed recovery..
I have noticed a block corruption issue in my RAC database. Its an index , how to recover a corrupted index in system datafile.
SELECT tablespace_name, segment_type, owner, segment_name FROM dba_extents WHERE file_id = 5 3 and 147551 between block_id AND block_id + blocks - 1; TABLESPACE_NAME SEGMENT_TYPE OWNER
I have no backup taken in my oracle server.Today morning i created a data file and unknowingly deleted it. Now i need to restore the datafile with its contents without using RMAN.

I would need to restore now from #8 ( full backup ) and #9 to #14 ( incremental backup )
Tell me the "restore command" to achieve the output?
We would take backup regulary by RMAN(catalog). Last two days we could not take backup. Backup start but after take backup some datafile then rman does not do anything.
I have restored all datafile to new location (that is ASM) earlier it was on file system using set new name command (RMAN). Now when i'm trying to update control file with swicth command it is prompting error. Version is 11g R2.

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.
Basic situation is this: Oracle 10g database, good RMAN backup from a few days ago. We lost one datafile due to storage corruption. I restored the datafile from RMAN, no problem, and started to roll forward with our archive logs. Problem: one log is corrupted, can't be read, no other copies of it. We are stuck, cannot roll forward any further. The database is up (all activity suspended for now) -- only this one file is offline. Everything else is fine.
My question: Can i do something similar to "open resetlogs" with just the one datafile? Most of what was in the file was indexes, which can be easily dropped & recreated. But a few extents were data which I want to retain. It's old data and the archive logs subsequent to the one on which we are stuck should be pretty much irrelevant. So if i can 'force' the datafile to open up, i believe we should be OK with the little bit of data that's in there, even if we don't apply the remaining archive logs. If it's not 100% consistent we can live with that.
Suppose our database have 100 datafiles and right now rman has completed backup of 64 datafile(from file no 1 to file no 64) and in process of backup of 65 number datafile. In mean time I executed some query and it has changed the file no 55. so now my question whether rman will go and bacup this datafile(datafile no 55) again or it will leave this file as it is?
I have one database which is fully restored from client backup (RMAN). Database was up and running perfectly. By mistake I have deleted one schema/user and its tablespace using drop command. I have RMAN backup so want to restore that schema's datafile from the backup but when I run below statement it throwing error :
run { allocate channel c1 device type disk ; set newname for datafile 45 to '/ora/oradata/JSIP1/data.dbf'; RESTORE datafile 45; switch datafile 45; recover datafile 45; SQL ' alter database datafile 45 online ' ; } RMAN-20201: datafile 45 not found in recovery catalog
or If I go and try to restore the tablespace of that schemas using below block it throws error:
run { allocate channel c1 device type disk ; RESTORE TABLESPACE DATA; RECOVER TABLESPACE DATA; SQL 'ALTER TABLESPACE DATA ONLINE'; } RMAN - 20202 Tablespace not found in the recovery catalog RMAN -06019 could not transalate tablespace name "DATA"
how to restored drop users and tablespace data from the RMAN backup.

Could we skip the backup of the above missing files using RMAN -> backup database skip inaccessible;On further research, this would compromise tablespace SYSAUX recoverability...Questions:
1) What caused the above missing files to get created? 2) What is recommended: Recover the datafiles?

As part of an incremental backup I recover copies of the tablespaces. These by default are stored in the disk backup location diskgroup. Is it possible to move these copies to another disk group / location whilst still backing up to the default disk backup location diskgroup. I know how to do it with the main datafiles but not with the copies. e.g.
Current situation: Original Datafiles in +DATA Backups in +FRA Recovered Datafile copies in +FRA
New setup to be: Original Datafiles in +DATA Backups in +FRA Recovered Datafile copies in +BACKUP

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.
