Pramod,

I Feel the problem with zax is in the system tablespace. The best bet for
him would be to Restore a Cold backup and if running in archive log mode
roll the db forward to the current time.

HTH

Zax,

First find out which object is having problem.

Execute the below sql

The following query will tell you the object TYPE , OWNER and NAME of
a segment given the absolute file number "<AFN>" and block number "<BL>" of
the corrupt block - the database must be open in order to use this query:

SELECT tablespace_name, segment type, owner, segment_name
FROM dba_extents
WHERE file_id = <AFN>
and <BL> between block_id AND block_id + blocks - 1
;

in your case, AFN=1 and BL=37749
