and even I cannot login into the DB via TOAD.

so logged into the unix server directly and invoked the sqlplus.

and then backed up the aud$ table and truncated the data in it.

SQL> select count(*) from aud$;

COUNT(*)
----------
143413



SQL> Create table Aud$_bkp tablespace users as select * from aud$ ;

Table created.

SQL> truncate table aud$;

Table truncated.

SQL> select count(*) from aud$;

COUNT(*)
----------
0


SQL> SELECT USER_NAME, AUDIT_OPTION, SUCCESS, FAILURE
FROM sys.dba_stmt_audit_opts
where SUCCESS='BY SESSION' or FAILURE='BY SESSION'
union
SELECT USER_NAME, PRIVILEGE, SUCCESS, FAILURE
FROM sys.dba_priv_audit_opts;

from the above output ran the noaudit to diable auditing.

SQL> noaudit ALTER PROFILE,CREATE ANY JOB ,CREATE ANY LIBRARY ,CREATE EXTERNAL JOB ,CREATE USER,DROP ANY TABLE,DROP USER , EXEMPT ACCESS POLICY ;

Noaudit succeeded.

SQL>
SQL> commit;

Commit complete.
