I am going through the Oracle VSS writer , trying out various methods. Just keen to know if this is the right place to ask VSS related questions as I could not find any post related to VSS.
For Volume based VSS shadow copy backups for a logged database, I am unsure about the restore method using VSS writer. Also oracle doc does not mention any steps for volume based restore of a logged (archive log mode db) database.
I have facing problem while taking backup on Windows 7 client of Oracle 11g R2 database. I have installed oracle 11gR2 for windows on windows 7 machine. I have created a directory like below in database.
On Database Server
SQL> create directory win_expdp_dir as 'd:expimp';
Directory created.
SQL> grant read, write on directory win_expdp_dir to lab;
Grant succeeded.
On Windows 7 machine (client machine)

I have give all sharing rights on d:expimp directory. My main question is why i'm getting this error. Is there any thing missing in setup. how to take export on windows 7 client.
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
Quote:ORA-19870: error reading backup
Here are the session details

We are using Oracle 10g R2 in Windows Server 2003. I'm trying to restore a database in a new server, using RMAN backups.
Our external consultant configured RMAN scripts for full and incremental backups but never tested them . Since he just doesn't show up, I'm forced to tested them, restoring the whole database in a new server.
My instance is named MTDPROD, and I will create all from scratch.
At current server, RMAN files are generated in: //192.168.1.149/g$/XXXSRV4-ArcLogs/MTDPROD/RMAN
At new server, I run all these commands:
C:>oradim -new -sid MTDPROD -intpwd mtdprod Instance created -- I created the relevant folder hierarchy under <ORACLE_BASE> directory -- Then, I created the relevant directories for Oracle Database, as follows: --a. Create BDUMP, CDUMP, and UDUMP directories under '<ORACLE_ BASE>
[code]....
By instance, I see a lot of this kind of files:
- FULL_MTDPROD_20110529_386_1.BAK - INCR_MTDPROD_20110621_480_7.BAK And only see these two files: - C-2169285856-20110527-03 - C-2169285856-20110527-04
It seems that this C-2169285856-.... files only were on 27/05/2011 and then no more. However, the FULL_... and INCR_.. files are generated every day. The FULL is generated at the end of each month and INCR is generated every day.
This is the backfull.sql:
run { allocate channel c1 type disk maxpiecesize=4G; CROSSCHECK archivelog all; backup incremental level 0 format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANFULL_
[code]....
This is the backincr.sql:
run { allocate channel c1 type disk maxpiecesize=4G; CROSSCHECK archivelog all; backup incremental level 1 cumulative format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANINCR_ %d_%T_%s_%p.bak'
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.

diagnose what actually occurred during RMAN backup?
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 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.
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 tryign to run a split onlike full backup from the os useign the sap command which is linked to rman..Command that i am useing is ...
brbackup -u / -c force -t online_split -m full -p initBR1_onlinefull.sap
The backup goes thru but i get this erro on the end...

I've read a lot about the different types of backup available with Oracle (hot and cold backup). However, I was thinking of a different way of performing this task. I'm currently using Windows Server 2008 R2 and Oracle 11g Standard Edition. I'd like to schedule an entire backup of my server via the utility "Windows Server Backup" (available for free).That way, I could recover my entire server with all the programs and files in case the latter crashes.I'm wondering if this solution could be used as a way of backing up (and recovering) the Oracle database. Should I still set up a regular hot backup with the Archivelog mode enabled in case some operations/transactions were being done at the time of the crash (for the data integrity)?
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.
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 ;
I am trying to setup incremental backup on my windows OS based server using RMAN command in batch file. When I use batch file in OS scheduler it is working fine, when I am calling same batch file from my LOCAL desktop PC it throws errors as below.

Tape streaming is not happening while performing RMAN tape backup. On investigation, you find that it is not because of the incremental backup or the empty file backup and that RMAN is sending data blocks to the tape drive fast enough.What could be a solution to make tape streaming happen during the backup?
A.Configure backup optimization
B.Configure the channel to increase MAXOPENFILES
C.Configure the channel to increase the capacity with the RATE parameter
D.Configure the channel to adjust the tape buffer size with the BLKSIZE option
We have the requirement of performance testing of our proposed production platform, for this i am asked to take RMAN backup of clean position (Say Day0 or baseline backup) and restore it multiple times for few rounds of testing. My question is after 1st restore (with set until time of day0 position) if i open the database with resetlogs, would i be able to restore same clean backup again? I am using control file in the environment instead of RMAN catalog database. What i can do to make this scenario work? I am already in preperation of setting rman catalog database.
