But this is a table, if I understood Howard correctly, an index organized
table. An index organized table is distinct information and does not have an
alternate source of data from which to be rebuilt.
(It puzzles me that an IOT can be disabled, by the way. I wouldn’t have thought
to attempt to make a table disabled.)
I would not put the extent this corrupt block resides in the list of extents
that can be allocated, so IF it is an empty table owned by an owner we can mess
and it is currently named “A” I would rename it to “B” and create table “A” as
select * from “B” where rownum < 1; Oh, instead of “B”, I would probably use
the name “previously_A_corrupt_do_not_drop” or something else you would never
drop.
Did they give you a bug number? There are some bugs that you can prevent
re-occurrence, which do not repair the “corruptness” of the existing block and
such that the corrupt block being acquired for direct insert is not good.
The original intent of the separate SYSMAN tablespace was to be stuff that
*could* be re-organized (as opposed to the SYSTEM tablespace). I can’t certify
that original intent was preserved.
If this is part of one of the toolsets that can be uninstalled and
re-installed, you still probably want to do the re-name before you drop that
table. If this were a well understood user tablespace, I would copy everything
in it to a new tablespace, drop the existing tablespace releasing the storage.
Then if I needed the tablespace to be the original name, I would re-create it
and copy the contents back and drop the temporary respository. (Tablespace
create should not be able to replicate the “corruptness” of the block as a
logical entity.)

Subject: Re: corrupt blocks WHAT WOULD YOU DO?
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
