Red face Oracle error gets changed during data recovery


We have a Wipro Net Power 8552 server on RAID 5 with Linux Advanced Server. The Databse is Oracle . Every time the reocovery is made the block corruption error gets changed. There are four hardisk in the Raid with 18 GB capacity of Quantum make. I want to make sure if any Utility is there in Linux to check the Harddisk if any Block corruption is there or Not.

Hi,

it will be nice to know:
- what version of Linux?
- what version of Oracle?
- what RAID controller?

Did you use Oracle's dbverify to verify datafiles?
Did you disable write cache on your controller for testing if the error occurs if the write cache is not used?

If you fix one error and get the next one, this seems to be a memory problem on your host or RAID controller.
Check host memory using something like memtest86.
