Is there any PERFORMANCE Overhead on Setting DB_BLOCK_CHECKING = TRUE
in the init.ora .
Any Best practice on this parameter Setting ?
Thanks

Peter - You can use the DBMS_REPAIR package included with Oracle to locate
the corrupt blocks. If the data in the corrupted blocks is extremely
important, you can use this to dump the block contents. Then you can change
the blocks so Oracle will skip the corrupted blocks. Then you can export the
table or copy the contents to another table.
Dropping the tables and recreating it from your export is also an
option.
Don't forget to rebuild indexes afterward.
Run ANALYZE TABLE VALIDATE CASCADE to find any other corrupt blocks
in other tables.
And turn on the init.ora parameter DB_BLOCK_CHECKING to detect any
further corruptions before they occur.
Good luck.

I have a system when I issued a select statement, I get the following error.
ORA-00604 Error Occur at recursive level 1
ORA-01578 Oracle Datablock corrupted. File 6 Block 2853
ORA-01110 Datafile 6 E:\ORANT\DATABASE\RBS1.DBS
We have an export that we may be able to restore. The database is running in non-archive mode. Any idea on how to resolve this problem?
Thank you in advance
