During the scheduled backup we observed that, backup got failed. Error is "ORA-01115: IO error reading block from file 11 (block # 118736)
".
unable to rectify it. Below are the part of log file -
ORA-39126: Worker unexpected fatal error in KUPW$WORKER.MAIN [TABLE_DATA:"DW_REP"."DW_MOTOR_CLAIM_INFO_DTLS"]

This is development server. Dont have RMAN configured.But when we connected to RMAN and issued block recovery, it started process and shows media recovery done. Since no RMAN backup was taken before, what it does here?

RMAN> CONECT target /

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

I have altered permissions on the backup files as well but of no use

and for such order i noticed that block change tracking file wasn't used for any cumulative backup. for each cumulative backup was done full scan over database.
it was used after i did incremental level 0 backup, and again incremental 1 cumulative.
if i want this feature to be usefull i should enable it before my incremental level 0, or i should do incremental level 0 immediately after i enable it?
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.
Does change in segment size effect the rman backup size..??
I'm trying to understand do Rman backup the empty block from datafiles..?? And if it escape the empty block than inserting data in tables (increasing the number of used block) might change the size of total backup (Rman) size
I just switched my STBDY DB to a PRIMARY DB and I am ran the following:

what causes this warning and how to get rid of it?
Quote: A.2.2 Writing Backup Scripts for Disk and Tape Scenarios
As in the disk-only scenarios, the backup scripts in this section are categorized based on database workload. as stated very clearly it depends on the workload, more precisely the rate of block change. The size of the database can be found out based on formula from
[URL]....
so how would I know the rate of block change in order to know which script is suitable for me? I try to find out the rate of block change for the database based on change tracking file but based on
[URL].....
Quote:
The size of the change tracking file is proportional to the size of the database and the number of enabled threads of redo. The size is not related to the frequency of updates to the database. So how do I determine the rate of change? can the rate of block change based on size of archive logs?
I have the following information with me:
starting from 5/10/2011 0101 ending 5/18/2011 1114
average size of each file 27,942,770,176/1644 =16996818.841849148418491484184915
average size of each day's log = 27,942,770,176/9.5 =2941344229.0526315789473684210526 about 3G
If I have a database size of 92G, based on the archive log size of about 3G per day, can I conclude that a change of 3G/92G is considered as few block change?
I have noticed a block corruption issue in my RAC database. Its an index , how to recover a corrupted index in system datafile.

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.
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.

We are facing block corruption error and it's refer to system datafile (SYSTEM01.DBF).Below is the script through it, we can come to know about the extent.
select segment_name, segment_type from dba_extents where file_id=1 and 134144 between block_id and block_id+blocks-1;
select owner,index_name,index_type, table_name from dba_indexes where index_name='I_CDEF3';
How to resolve the problem as it is related to system datafile? We tried to drop the index but system is not allowing to do.

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.
