I would like to know that if I enable backup Optimization on then incremental full backup skip any files which was earlier backup? Because we may know that backup Optimization on ensure skip those files which are already taken backup.
Database : oracle 10g 10.2.0.3 .
I have a Tablespace DP_TS_LOBS and i stores only secure file blobs in it. DP_TS_LOBS has only one datafile "LOB1.dbf" . I have RAMN optimization parameter on. I also have the backup of DP_TS_LOBS tablespace.
RMAN> backup tablespace dp_ts_lobs;
after storing few blobs the data file "LOB1.DBF" got full and added a new data file "LOB2.DBF". Few more BLOB's were stored to DP_TS_LOBS tablespace. Then I tried to backup the DP_TS_LOBS table space again, as expected both the data file were backed up as there were changes to both the datafile since last backup.
I was expecting with Optimization Parameter on, if RMAN has a datafile with same DBID, checkpoint SCN, creation SCN,RESETLOGS SCN,time already in the backup and data file is offline RMAN wont backup that data file again.
After few minutes with out performing any activities in the database, I put the "LOB1.DBF" to offline and executed the DP_TS_LOBS table space backup again but I still see RMAN backing up the both the data files.
I was closely monitoring the "CHECKPOINT_CHANGE#" and "CHECKPOINT_TIME" columns of v$datafile, the values for those columns changes for data files "LOB1.DBF" and "LOB2.DBF" when I execute backup tablespace command on DP_TS_LOBS even thought there was not any activity in the database to add or update or delete blob that are stored in DP_TS_LOBS table space.
Initially I thought it can be due to some unwritten committed blocks of dp_ts_lobs table space in the memory that got written to the datafiles while executing backup tablespace command and that why i saw the change in checkpoint scn and checkpoint time , but it keeps happening every time when I tried multiple times.
I had a production db with archive logging enabled

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;

We have a host for restore purposes. We execute monthly or quarterly restore operations to verify that I am able to restore a subset of the data in the given amount of time or to other purposes. I have a automated script to Clone the Database, but to Clone Database we need remove the old database from ASM before start this operation. I want remove only Database files and keep the configuration (such as oratab/network/ocr and so on).
Question: There is a easy way to remove these files without connect on ASM or by using DBCA?
Accidentally without checking the channel allocation I have given the backup archivelog from sequence until sequence with delete input. This backup piece went to the disk but it should go to Tape.I know that we can catalog this backup piece but I want to move this backup files in disk to Tape using RMAN. Is there anyway or I have to lie with Backup team or OS team for this file movement?

View 4 Replies View RelatedI took backup of Datafiles , archivelog files and controlfile through RMAN. Now, i want 3 backup file will created as a output of RMAN operation. It would be :
1 backupfile for all the datafiles
1 backupfile for all the archivelog files
1 backupfile for controlfile.
It have to be regardlessly whatevr my DB size is. It it possible to do so. How i can can write rman script to accomplish the task.
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.
I am studying about these two technologies and the only difference that I found was that optimization doesn't backup the duplicated archivedlogs.
If both ignore not changed blocks, what is more effective?
The optimization backup also has some tracking file?
understanding rman scn based Backup Algorithm .. In SCN based backup do rman generate backup from archivelogs ???
View 1 Replies View RelatedI am having a issue, we are trying to restore our db from control files using Symantec Backup exec, but job fails giving me error go to table spaces select all table spaces and unchecked roll forward.
i am unable to find way to uncheck the table spaces. Here is the complete description.
Cause
The system catalog tablespace "syscatspace" contains all of the system catalog information for the tables. Syscatspace needs to be rolled forward first, and then the other tablespaces must be rolled forward.
Solution
Workaround:
When the restore operation is run from a tablespace level backup, perform the rollforward for the syscatspace tablespace first and then for other tablespaces.
Execute the rollforward operation as a DBA operation. The sequence of the recovery process should be as follows:
1. Select all tablespaces, uncheck the rollforward option and run the restore job.
2. Run the rollforward operation as a DBA initiated operation:
rollforward syscatspace to point in time / end of logs. e.g. db2 => rollforward database UEXIT to end of logs and complete Tablespace (SYSCATSPACE) online
3. Perform rollforward of all other tablespaces.
e.g. db2 => rollforward database UEXIT to end of logs and complete tablespace (SYSTOO LSPACE,USERSPACE1) online
Refer to IBM DB2 documentation for more information on DBA-initiated operations.
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.
RMAN> run
2> {
3> allocate channel c1 device type disk

When we backup .arc files we issue a RMAN command similiar to this:
KEEP_ARCHIVE_HOURS=2
rman <<EOT
connect target ....
connect catalog ...
sql "alter system archive log current";
[code]....
The problem is at times there may not be any archive files that meet this criteria and RMAN throws an error
RMAN-06004: ORACLE error from recovery catalog database: RMAN-20242: specification does not match any archived log in the recovery catalog
I was considering using the following code to see if there are any available .arc files that meet the backup criteria.
set pagesize 0 feedback off verify off heading off echo off;
select count(1) from v$archived_log where
COMPLETION_TIME < sysdate-$KEEP_ARCHIVE_HOURS/24
and backup_count = 0 and name is not null;
While testing on several systems, I found that the above-mentioned query picked up some redo-logs (*.rdo) I can only assume that these redo logs were used for a DB recovery.

I have a few questions:
1) Is my assumtion correct about the .rdo files in the v$archived_logs table
2) I would hate to add special logic and look for something like name substr(name, *.arc) (pardon the syntax). Therefore, is there a way to get rid of these *.rdo files?
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)

Now,i want to implement hot backup on my oracle database which install the linux operation system ,but i expect the hot backup files can storage on the servers of the Windows operation system directly.
I have one question to clarify regarding backup.
There is an incident that in production database 1000 archive log files generated.From 1000 files, 100 archive log files have been removed.When i take incremental backup next day , what will happen in database?
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?

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.

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.
