Re: Undo tablespace offline and ORA-00376

Riyaj Shamsudeen


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.

2 Node RAC,, Sun OS 2.8

We created new undo tablespaces (UNDO3, UNDO4) for each node1 and
node2 respectively and changed default undo tablespace to UNDO3 and
UNDO4. Then we put old UNDO tablespaces offline.

After 2 days we are trying to create a new index and it gives the
following error.

Any idea?

ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-00376: file 2 cannot be read at this time
ORA-01110: data file 2: '/u01/oradata/pdw/undotbs01.dbf'

Luckily the tablespace is still offline and I can bring it online. But
I just wanted to know teh reason behind this?
