Re: corrupt blocks WHAT WOULD YOU DO?

I hads a primary database server crash one time and an index having to do with clustered tables was clobbered such that the index and the table were in disagreement. I was told by Oracle support that the index couldn't be rebuilt as it was a "bootstrap" object which I took to mean anything built by calling sql.bsq; i.e, the data dictionary. The physical standby was in good shape, I cannot remember if we switched over of failed over.

The old primary was fine except when the indexed was called.

What is the name of the object?

I wouldn't accept Oracle's "fix" either way. If it's an index, regardless of what index it is, it can be dropped and re-created to rid of the corrupt blocks.

Smells like they're looking for the "easy way out" here.

I have corrupt blocks in the sysman ts. Oracle tell me to rebuild my database. Its 1/2 TB and I don't really want the downtime. Its in a MGMT Flow index which I don't think we use anyway and the index is disabled. I don't have an RMAN backup old enough to repair. What would you do?

I do have two plans

Turn on flashback and try dropping and recreating the objects.

Its an IOT so cant be rebuilt online.

Other plan - Ignore it. Does it matter?

I seem to recall many years ago being told by Oracle to rebuild the AUD$ table index which had corrupted and caused logins to fail.

Best Wishes
