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..
View 7 RepliesI 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 take manually backup of datafile..using OS command
View 1 Replies View Relateddoes, block change tracking file is read during incremental level 0 backup?
View 4 Replies View Relatedi did such commands
1. RMAN -> backup incremental level 0 database;
2. SQLPLUS -> alter database enable block change tracking using file '/home/oracle/block_change_tracking.tr';
3. RMAN -> backup incremental level 1 cumulative database;
4. RMAN -> backup incremental level 1 cumulative database;
5. RMAN -> backup incremental level 1 cumulative database;
and for such order i noticed that block change tracking file wasn't used for any cumulative backup. for each cumulative backup was done full scan over database.
it was used after i did incremental level 0 backup, and again incremental 1 cumulative.
if i want this feature to be usefull i should enable it before my incremental level 0, or i should do incremental level 0 immediately after i enable it?

Suppose I take a multi stream backup, say 3 streams.
So if a control file is backed up in say backup set 1, so is the whole control file is backed up in one backup piece or it may span multiple pieces?
A backup set may have multiple backup pieces.
I want to ask if I restore a control file from backup of say day2 and I recover till day1 using RMAN script, then what will be the state of my database? I mean day2 control file may be having SCN-Day2, and I am instructing RMAN to recover till past point in time that is SCN-Day1.

I have an oracle autoback of controlfile and spfile. I am trying to restore the production database using this backup, into a new server with a different directory structure.
I have completed the following steps in the restore process.
1. Creating a pfile from spfile
2. Changing the the location of cdump, udump, bdump and the control files ( there are three )
3. Then creating a spfile from this pfile
I am stuck on the next step where to rename all the datafiles and tempfile and restore the database. Following is what I did.
After mounting the database in RMAN, tried to run the following.

I take hot backup of database at 10:00 am.After taking the hot backup 50 archived logs are created.Out of 50 i have backed up first 25 of them and at 5:00pm i lose complete database including control,data and the last 25 archived log files that were not backed up.So I am using latest hot backup to recover
I restore the control file backup and datafile backup taken during ho tbackup(10 am) and i issue the command
.......startup mount
>>>>>>>Recover database until cancel
!!!!!!! Apply the available 25 archive logs
then i give "cancel" since I dont have the next redo log .Now in which mode will the database open(Reset logs or no reset logs)
I want to restore control file from backup set,just as the flowing command,where location does the control file be restored to? how can i specify the location when restore control file?
restore controlfile from '/u01/rman_backup/mybak/df_768589733_7_1.bak';
taking the backup of a control file, as i am taking online backup, archive mode.
At first i have executed the statement
sql> alter database backup control file to trace;
then i have removed the control files and enterd some data in a table and committed it.As my oracle is not shutting down, so i shut aborted it. Now after saving the last file from the udump as obkp.sql i am unable to edit this file and use.
how to edit and use this file, so that i can startup my database normally.
When i issue this command ,how many times to backup controlfile?
RMAN> BACKUP CURRENT CONTROLFILE INCLUDE CURRENT CONTROLFILE;
Is there difference between 'BACKUP CURRENT CONTROLFILE INCLUDE CURRENT CONTROLFILE' and 'BACKUP CURRENT CONTROLFILE'?

10.2 Oracle database on Linux
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 ?

A.2.2 Writing Backup Scripts for Disk and Tape Scenarios
As in the disk-only scenarios, the backup scripts in this section are categorized based on database workload. as stated very clearly it depends on the workload, more precisely the rate of block change. The size of the database can be found out based on formula from

so how would I know the rate of block change in order to know which script is suitable for me? I try to find out the rate of block change for the database based on change tracking file but based on

Quote:
The size of the change tracking file is proportional to the size of the database and the number of enabled threads of redo. The size is not related to the frequency of updates to the database. So how do I determine the rate of change? can the rate of block change based on size of archive logs?

about 3G
If I have a database size of 92G, based on the archive log size of about 3G per day, can I conclude that a change of 3G/92G is considered as few block change?
changing archive mode during DB running.Before in 9.2, 'ALTER SYSTEM ARCHIVE LOG START/STOP' is available for this job. But, after 10g/11g, it cause 'archive log stop has been deprecated'.
However, for my practice, I need to estimate archived logs size before backup them, so I need to stop archive log for a while and enable it later during DB running.
I check Oracle documents, it only mentions changing archive log mode at DB mounted but not open.
I want to change my archive log destination currently my database its in archive mode and this archive log detail as under
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination F:archivelogs

this my f drive space is full so i want to change this my archive destination to my another g drive so how can i do this.and if i change this my archive destination does its affect any problem while recover my database in future.
