Home -> Community -> Mailing Lists -> Oracle-L -> Self-Healing ORA-01578's
This actually happened to me Saturday Night:
Running my 4-way Linux box (4.21 Kernel) with 9.2.0 (and using a SAN for my disks) I discovered a ORA-01578. After several hours of work with Oracle support, running dbverify, and creating test queries, we determined that there really was block corruption.
We used dbms_repair to get everything but the bad block, and were getting ready to see what would happen on a tablespace recovery, when the backup group decided to stop the instance to do a cold backup (I work for a large organization, with every task subdivided, with little communication).
When the instance came back up the block corruption was gone. This is the one part of the whole affair that I find incredible. Does someone have an idea as to how bouncing an instance can fix block corruption which was proven by dbverivy?
