Hi,
I am using Solaris 9 and Oracle 9.2 .

I did this

-->

SQL> ! ps -ef | grep pmon
  oracle  4531  4529  0 08:15:41 pts/7    0:00 grep pmon
  oracle   556     1  0   Oct 19 ?        0:01 ora_pmon_testdb
SQL> oradebug setospid 564
Oracle pid: 6, Unix process pid: 564, image: oracle@dogmatix (SMON)
SQL> oradebug ipc
Information written to trace file.
SQL> !ls -lat $ORACLE_BASE/admin/testdb/udump |head
total 668
drwxr-xr-x   2 oracle   oinstall    2560 Oct 19 06:31 .
-rw-r-----   1 oracle   oinstall     695 Oct 19 06:31 testdb_ora_571.trc
-rw-r-----   1 oracle   oinstall     611 Oct 19 05:32 testdb_ora_679.trc

no new trace file created at udump location , so i tried this

-->

SQL> SELECT pid FROM v$process 
    WHERE addr = ( SELECT paddr FROM v$bgprocess
                 WHERE name = 'SMON');
       PID
----------
         6

SQL> oradebug setorapid 6
Unix process pid: 564, image: oracle@dogmatix (SMON)
SQL> oradebug ipc
Information written to trace file.
SQL> !ls -lat $ORACLE_BASE/admin/testdb/udump |head
total 668
drwxr-xr-x   2 oracle   oinstall    2560 Oct 19 06:31 .
-rw-r-----   1 oracle   oinstall     695 Oct 19 06:31 testdb_ora_571.trc
-rw-r-----   1 oracle   oinstall     611 Oct 19 05:32 testdb_ora_679.trc

then again, no new trace file found.

Am i missing something or doing something wrong.

thanks & regards,
tarun

hi mahesh,

Even i tried the same again, see this

SQL> select pid from v$process
  2  where addr = (select paddr from v$bgprocess
  3  where name='SMON');

       PID
----------
         6

SQL> oradebug setorapid 6
Unix process pid: 564, image: oracle@dogmatix (SMON)
SQL> ! ls -lrt $ORACLE_BASE/admin/testdb/udump
total 0

SQL> oradebug ipc
Information written to trace file.
SQL> ! ls -lrt $ORACLE_BASE/admin/testdb/udump
total 0

Why i am not getting any trace file??

[Edit: Sorry but its pointing to bdump location , i just checked]

SQL> oradebug tracefile_name
/data1/u01/app/oracle/admin/testdb/bdump/testdb_smon_564.trc
