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 ;

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.

We are exploring Oracle Secure Backup in our environment as legato networker alternative. But RMAN backup in OSB is very slow due to sbt wait event (sbtwrite2). it can backup 5GB/hour. We think this not normal behavior. we have checked network throughput between media server and client server. It can send 50 GB data by 30 min.

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?

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 .

Environment: 2 Node Oracle(10.2.0.4.0) RAC on Aix 6.1.
Backups using RMAN utility.Our system is configured to take backups on Tape library using TSM server.
We take incremental level 1 backup on all days and Level 0 backup on Wednesday.We would like to keep the RMAN retention period of 14 days.I delete the backups that are 7 days old from the disk to save space and 14 days older backup from Tape.
I am getting below error in my RMAN backup logfiles.Also attached
RMAN-06207: WARNING: 147 objects could not be deleted for DISK channel(s) due
RMAN-06208: to mismatched status. Use CROSSCHECK command to fix status
RMAN-06210: List of Mismatched objects
RMAN-06211: ==========================
RMAN-06212: Object Type Filename/Handle
RMAN-06213: --------------- ---------------------------------------------------
The configuration of RMAN is:
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 14 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO 'SBT_TAPE';
CONFIGURE CONTROLFILE AUTOBACKUP ON;
[code].....
How to avoid this error ? Can we set "Retention period" as 14 days in RMAN level and delete the backups in disk which is older than 7 days?Should the deletion of tape backup be handled in TSM level ?

I've done a crosscheck backup in RMAN and the list of expired objects has actually gone down, in number, from the last time I did this ( 2 weeks prior). We do NOT delete anything from our RMAN catalog on a routine basis (ie. no "DELETE EXPIRED BACKUP commands were issued) so normally the list of expired backup objects increases with each RMAN maintenance task we do. Why the number of expired objects might actually go down in this particular instance ?

Two questions.
1. Both Oracle Secure Backup and Oracle Secure Backup Express for x86 Solaris download the same file.
Is there no difference on Solaris?
2. Have installed and configured sgen driver and tapes can be labelled OK and the first backup works
BUT appending the next backup to the tape I get the following.
Space to EOD.
BSR
Device says it is offline

My scenario:
We have OSB 10.44 installed on 64 Bit Red Hat OS. Is working pretty fine with a Virtual Library that is configured in an Storage Box. Now we have acquired a Physical Storage and we want to duplicate the backups already taken by the Virtual Library into the new Physical Library.
We have 20 drives for the VTL and for the physical we are planning to have the same to duplicate all backups from VTL. That is being done in case Emergency Failures, so we can restore from Physical Library in case the VTL fails.
The question is: Is there any documentation on how to do duplicate backups.?
The duplicate backups copy wont be done in real time. They will be done after the backup is finished in the VTL and then will start the copy in the physical library.

We are trying to use the SFTp transport in OSB 11g. Did the setup as mentioned in the documentation.The SFTP server is hosted on linux machine and using the user password mechanism.
We are reading a file using the ftp adapter and routing to the business service that is based on sftp.The file is picked up properly by proxy but while sending the file through SFTP, we are facing the following error.At the source and destination ends, the directories have the full permissions as required.

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)

We observed that our RMAN backup was taking more time to complete. CROSSCHECK is the main culprit as because of having data in the catalog for more than 3 years.
So in the part of script we added delte obsolete recovery windoe of 14 days. (Redundancey 1).
Here the problem is we are getting error as
RMAN-03002 - failure of delete command
RMAN-06091 - NO channel allocated for maintenance (of an appropriate type).
Reason: Till 2 years back the backup was stored in tape and after that it got changed to disk. So allocating channel disk to delete obsolet is not working. How we can over come this.
We tried like allocating channel tape sbt_type. It got failed as no media manager information configured. We dont have that information.
How we can overcome this.

Although the retention policy is set to "CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 60 DAYS;", when running delete obsolete or report obsolete it deletes or returns all the backupsets till sysdate. What should I do to solve this issue?

I have following query in Dataguard ..
If I want to take Rman archive log backup with delete input command , how the archive logs will be copied to standby database
For eg
I am taking archive backup as
RMAN>backup archivelog all delete input;
here consider few archives are not copied to standby database (due to nw issue) then how standby will receives these missing archives as those are deleted by rman backup at primary side.
I am not getting any document related to above query.
