OPS$DAEMON coming from apps server
« on: Jun 11th, 2010, 5:49pm »		 Quote | Modify
After setting up some initial auditing I see very frequent connections by OPS$DAEMON coming from the application server (running OAS).
 
SQL> select user_name,
  2  nvl(proxy_name,'NULL') proxy_name,
  3  privilege,
  4  success,
  5  failure
  6  from dba_priv_audit_opts
  7  where user_name='OPS$DAEMON';
 
USER_NAME  PROXY_NAME PRIVILEGE  SUCCESS    FAILURE
---------- ---------- --------------- ---------- ----------
OPS$DAEMON NULL  CREATE SESSION  BY ACCESS  BY ACCESS
 
SQL> select timestamp,
  2  nvl(os_username,'NULL') osuser,
  3  username,
  4  userhost,
  5  nvl(terminal,'NULL') terminal,
  6  action_name
  7  from dba_audit_trail
  8  where username = 'OPS$DAEMON'
  9  and timestamp > sysdate -1/96
 10  order by timestamp desc;
 
TIMESTAMP  OSUSER     USERNAME   USERHOST   TERMINAL   ACTION_NAME
-------------------- ---------- ---------- --------------- ---------- ----------------------------
11-jun-2010 10:57:49 NULL  OPS$DAEMON *************** NULL  LOGOFF
 
 
First, I don't know why the connections would be using OPS$DAEMON instead of the user supplied credentials, second I don't understand why I see only LOGOFF, but no associated LOGON.

Hi Ed,
 
I tried the same with a simple example in my database:
 
 
first check audit settings  
 
SQL> set serveroutput on size 1000000
SQL> exec print_table('select * from dba_priv_audit_opts where privilege=''CREATE SESSION''');
USER_NAME      :
PROXY_NAME     :
PRIVILEGE      : CREATE SESSION
SUCCESS        : BY ACCESS
FAILURE        : BY ACCESS
-----------------
 
Create a sample user and connect
 
SQL> connect sys/oracle1@ora11gpe as sysdba
Connected.
SQL> create user aud identified by aud;
 
User created.
 
SQL> grant create session to aud;
 
Grant succeeded.
 
SQL> connect aud/aud@ora11gpe
Connected.
 
Test the audit trail in a dfiffernet session whilst still connected in the first:
 
SQL> set serveroutput on size 1000000
SQL> select timestamp,username,os_username,action_name
  2  from dba_audit_trail
  3  where username='AUD';
 
TIMESTAMP USERNAME
--------- ------------------------------
OS_USERNAME
------------------------------------------------------------------
ACTION_NAME
----------------------------
14-JUN-10 AUD
Pete
LOGON
 
then exit the user AUD's session
 
SQL> exit
Disconnected from Personal Oracle Database 11g Release 11.1.0.7.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
 
C:\tools>
 
Then check the audit trail from a seperate session,
 
SQL> /
 
TIMESTAMP USERNAME
--------- ------------------------------
OS_USERNAME
----------------------------------------------
ACTION_NAME
----------------------------
14-JUN-10 AUD
Pete
LOGON
 
14-JUN-10 AUD
 
LOGOFF
 
There are two seperate records as expected. Can you check a complete session for OPS$DAEMON and see what else is in it. Maybe you hacve some other audit settings by session and then the LOGON will be reused by further audit actions. The LOGOFF would be a new record because its set by ACCESS. can you list out your audit settings?
 
cheers
 
Pete

Pete,
 
Thanks for the reply.  I'm out of the office for the next couple of weeks, but I'll follow up on this as soon as I get back.
