Oracle 10gR2 on red hat.
I have an application that writes blobs via pro*c. It is running at several sites without errors for a few years now. One of the newer sites has started reporting "ora-01578 ORACLE data block corrupted".
I've tried using rman backup validate - it does not report any errors.
I've tried using rman restore and recover to correct the problem.
I've tried deleting the file with the corrupt block and using rman restore and recover to recreate it.
In any of the above cases, I do not see any errors being encountered, and when I restart the application, it works for a while and then starts reporting "ora-01578 ORACLE data block corrupted".
I've had the client do a physical check of the disk and it indicated the media was okay.
We've failed over to the standby system, so I have a wee bit of breathing room - but I'm going to be away for 4 days and will have to get back on this when I get back. I'm a little puzzled that I can fix it for a short while and then it breaks again.

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.
ORA-00701 - object necessary for warmstarting database cannot be altered.

I am having 3 oracle database instances running on 3 seperate Linux Node(RHEL Node).
Instance -1 named - DS
Instance -2 named - MIS
Instance -3 named - OAS
Among of these 3 nodes, we are facing Block Corruption issues with sysaux tablespace.Error in Instance name DS is

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 am facing issue of block corruption in my exp backup which I am taking through expdp command. (Refer Attachment of Screen shot of error)
I want to know few things about the block corruption.
1. Why the block corruption occur.
2. How can I resolve this.
3. Can I rosolve this by deleting the same record on which this error is coming. if yes then how can I track that row in a table.
I already tried for DB verify utility. It shows the below result.

have a repeatable technique for damaging a datafile block?
I need to demonstrate and contrast various recovery techniques, such as dbms_repair, RMAN block recovery, and Data Guard automatic block repair.
I'll end up with a shell script (or batch file) where I can enter a file number and block number, and wipe out that block.

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

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

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
this constitute to 9.5 days

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 did such commands
1. RMAN -> backup incremental level 0 database;
2. SQLPLUS -> alter database enable block change tracking using file '/home/oracle/block_change_tracking.tr';
3. RMAN -> backup incremental level 1 cumulative database;
4. RMAN -> backup incremental level 1 cumulative database;
5. RMAN -> backup incremental level 1 cumulative database;
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?

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
4> ;
5> @/home/oracle/rman_scripts/newloc.rman
6> SET NEWNAME FOR DATAFILE 1 TO '/u02/oradata/dorian/system01.dbf';

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 set 'maxopenfiles 4' when allocating channel to sbt in my products env, I got 2 backup pieces in one backup set because that tablespace has 7 datafiles. Other configuration is kept as default, such as no maxsize, no MAXPIECESIZE, and etc setting.
I read document from Oracle. It says:"By default a backup set contains one backup piece. To restrict the size of each backup piece, specify the MAXPIECESIZE option of the CONFIGURE CHANNEL or ALLOCATE CHANNEL commands. " And also, maxopenfiles configure does not force another backup piece generated. So, why do I get another backup piece?
BTW, I tried this on another testing environment. I only get one backup piece even there are more than 2 times maxopnefiles datafiles.

When you create a backup in SQL Server, whether the backup is on disk or on tape, SQL Server writes the letters TAPE to the first four bytes of the backup. Does Oracle write any specify value to the front of every backup, and if so, what are the first four bytes?
