RMAN :: So Many Backup-pieces After Adding New File System
Jun 10, 2012
I faced one strange behaviour of rman backup after adding new file system for datafiles . I have OMF datafiles . 4 days ago i had only one file system /data01 and my DB_CREATE_FILE_DEST is set to /data01. my rman backup was creating 14 to 15 bacup pieces with parallelism 5 . which is normal with 84 datafiles .Now i added one more file system /data02 . but after adding this file system rman backup is creating so many backup-pieces around (40-45) with same rman configuration . nothing changes at rman script .

Is this script is enough to delete the backup pieces older than 2 days.
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS;
configure device type disk parallelism 1 backup type to compressed backupset;
run
{
allocate channel d1 type disk ;
backup filesperset 5 format '/u06/backup/EBSDEV/EBSDEV_data_t%t_s%s_p%p' database ;
sql 'alter system archive log current' ;
backup filesperset 20 format '/u06/backup/EBSDV3/EBSDV3_arch_t%t_s%s_p%p' archivelog all delete input ;
[Code]....

A full, online backup (database, archived redo logs, and control file autobackup) is done with rman ("nocatalog", Oracle 9i on AIX 5.2) daily. A media manger is not in use, so the backup is written to disk, then written to tape using an operating system utility. There is room on disk for two full backups, so "redundancy = 1" and obsolete backup sets are deleted to free up space immediately before running the next backup. If the backup(s) on disk are lost and the tapes containing these backups are lost, will it be possible to restore a tape containing older "deleted" backups (using an operating system utility) and catalog each backup piece in the current control file? In other words, can backups considered "deleted" in the control file be reintroduced if they're available on tape?

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.

is there any way I can add the DBID to my rman backup name? I've already tried %F/%f as seen in the man page. but this option remains ignored.
It works for the rman backup of the control file. but no change to get this running proper for the datafiles.

This is what I run
run {
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/dd_oraback/tkprod/%F';
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 22 DAYS;
sql 'alter system archive log current';
[code]...
So /dd_oraback is a Data Domain mount. Not sure if that makes any difference or not.

I'm trying to write a bat file for the rman backups that can be used for any of our databases. I'm passing variables into the bat file and that is working fine (i.e. oracle_sid, drive letter, oracle_home), my problem is when the rman actually runs and calls the ctl file, the variables aren't being passed thru to that file.

During the last week, we faced many network issues that prevent our RMAN files to be copied completely. Backup team offer a temporary solution that we have to generate only one backup file to be transferred from source to destination (tape).

I have a RUN file within a script to duplicate a database. As part of this RUN file I also run the command configure controlfile autobackup off; as part of this RUN file. However, this command has turned off backup of the control file on the AUXILLARY database (i.e. production) as well as the TARGET database (test). Is this supposed to happen?
My run file is:
rman TARGET sys/XXXX@${DB}-SOURCE AUXILIARY /
RUN {
allocate AUXILIARY channel a1 type disk;
allocate AUXILIARY channel a2 type disk;
allocate AUXILIARY channel a3 type disk;
allocate AUXILIARY channel a4 type disk;

Can the control file be used to store scripts which are used to perform backups? I know the RMAN recovery catalog can.
Does the SHOW command display detailed reporting on the RMAN catalog contents other than configuration information?

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 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)

review/correct my steps for adding an entry to the orapwd file.Is there an environment variable I need to set to tell it the name of the password file. In addition, how do I get a "user" in the password file when orapwd accepts file, password and entries as paramaters. Does this mean I need to give user "sys" sysdba privs?

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?
