Is there any way I can get all the archive log files present in a backup piece. I tried following but it always gives me all the log files for each piece:
****
SQL> select s.set_stamp, s.set_count, s.PIECES, s.backup_type,
s.controlfile_included from v$backup_set s, v$backup_piece p where
s.set_stamp=p.set_stamp and s.set_count=p.set_count and
p.handle='5mjv4do0_1_1';

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 doing RMAN Duplicate set until time to refresh daily our test database for our developers and it taking long time to finish. We noticed on the restore log that RMAN was using a day old old backup pieces to refresh the test database and don't immediately use the latest backup pieces instead.
For additional details here's the rman duplicate command we are using which we run daily(mon-sat) at 4am once daily full backup on production completed.
RMAN Duplicate commands:
run
{
set until time "to_date(to_char(sysdate,'Mon DD YYYY') || ' 04:00:00', 'Mon DD YYYY HH24:MI:SS')";
allocate auxiliary channel ch1 type disk;
duplicate target database to testdb;
}
exit
Is there a way on how to let RMAN use the latest backup pieces instead?
I am trying to clone a database on another server with different direcory structure. So that path on the source db server are /u04 whereas on on target db server it would be /u03.
Since this I am testing it on small database initially I have kept all datafiles, backup and archivelogs at /u04 and /u03 on the source and target db servers respectively Now I have copied the backups from source db server to target and since path is changed, I cataloged it
However during restore I am getting

I set 'maxopenfiles 4' when allocating channel to sbt in my products env, I got 2 backup pieces in one backup set because that tablespace has 7 datafiles. Other configuration is kept as default, such as no maxsize, no MAXPIECESIZE, and etc setting.
I read document from Oracle. It says:"By default a backup set contains one backup piece. To restrict the size of each backup piece, specify the MAXPIECESIZE option of the CONFIGURE CHANNEL or ALLOCATE CHANNEL commands. " And also, maxopenfiles configure does not force another backup piece generated. So, why do I get another backup piece?
BTW, I tried this on another testing environment. I only get one backup piece even there are more than 2 times maxopnefiles datafiles.
Backup entire database, without archived logs, while the database is open for user activity and also This backup should be the base for an incremental backup strategy.

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> }
My supervisor wants to remove all the archivelogs since it was just a test for 1 year the DB is not actually YET been used. Problem is they want it to be used as soon as possible w/o recreating again the database and just removing some data on tables and removed archive logs. how to safely removed the existing archived logs and create a full backup with archived fresh to sequence 1.

We are trying to restore a database to a cold backup DBID.However while our datafiles were backuped up for 6 months retention we found out subsequent delete obsolete command wiped out the Control file related to this backup piece..Now what is left with this backup piece is just datafiles..
Can we still recover the database with a subsequent controlfile autobackup for the same DBID.?

Is there anyway that i can get my archive log created on network drive instead of local drive.
As we want to save our storage space and want to keep archivelog on network.
Is there a way that if Archive log creation on Network drives falis, Oracle create Archivelog on Local drive.
We are running Data warehouse and on daily basis we have 22 to 25 Gig of Archive log created
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
[Code]...
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.
Is there any view in oracle 9i like V$RECOVERY_FILE_DEST where we can check the archive destination space utilization from database end ?
