RE: Unable to recover datafile - urgent

Manjula,

You are stuck. Schedule down time to export all of the tables from the tablespace that this file is attached to.

Then issue a 'drop tablespace including contents' command. Recreate the tablespace and import the data you exported.

You might be able to salvage some of the data from the POLINE table. Try querying the table. The records that are displayed you can save. The rest are gone.

Good Luck!

Unfortunately, there are 85 blocks in that datafile.

SQL> select * from dba_extents
  2 where file_id=48 and extent_id=225;

OWNER SEGMENT_NAME PARTITION_NAME

--------------- -------------------- ------------------------------
SEGMENT_TYPE       TABLESPACE_NAME                 EXTENT_ID    FILE_ID
------------------ ------------------------------ ---------- ----------
  BLOCK_ID      BYTES     BLOCKS RELATIVE_FNO
---------- ---------- ---------- ------------
LAWSON          POLINE
TABLE              LAWDATA01                             225         48
         2     348160         85           48

What would be the best way to get around this situation? We do not have the archive log required to recover that datafile.

Thanks...
