Home -> Community -> Mailing Lists -> Oracle-L -> Re: Undo tablespace offline and ORA-00376
('binary' encoding is not supported, stored as-is)
Is it possible that few blocks of abc_stage table is not clean ? Meaning
block clean out is not complete for those blocks ? Oracle might be
trying to check whether the pending transactions in those blocks are
committed or not, by accessing the old undo segment header. Since undo
tablespace is offline, this error is thrown.
BTW check whether sys.undo$ table has entries for those old undo segments.
To confirm you could trace (10046) the statement, find the block read just before this error, dump the block to see whether any ITL entries pointing to old undo segments.
Better yet, you could just alter the tablespace online, create index and then drop the undo tablespace.
Thanks
