Oracle recover object ORA00600: internal error code, arguments: [ktspScanInitd], [58759497],

Question: what is the 2nd argument? [58759497]

Situation:

No nightly exports/datapumps we have nightly RMAN backups.

There is a known Oracle Bug 11791664 with inconsistent metadata in ASSM segments with NO workarounds listed

The object is in a specific tablespace (REPORTING) separate from our main tablespaces

DBMS_REPAIR.CHECK_OBJECT fails with the same error

Exp fails with the same error

create table as select from fails with same error

I know I can restore the production database to a copy on another server but other than that what are my options here? Can I recover just the tablespace or will that regenerate the same problem once the tablespace is recovered?

Any suggestions are much appreciated.

I have never seen this error, so everything below are just assumptions:

In case the BUG only affects the write into the data file, but not it’s

corresponding data in redo / archive, you have a chance you can export the

data there. Please

ask Oracle Support for details on this BUG.

there is a tool called BBED to edit blocks in data files directly. I don’t

know if it can handle your problem I’ve

never done it.

there are some DUL (Data UnLoader) [e.g.  http://www.parnassusdata.com/en/emergency-services ] tools

available which export data directly from datafiles. maybe they can unload

data even with broken ASSM data.

There are probably more ways to address this problem.
