System Account Locked by 8 minute interval login attempts

edited May 23, 2012 9:46AM in Database Administration (MOSC) 7 commentsAnswered
Something is attempting to access our Oracle database every 8 minutes using the system account. We have the profile set to lock accounts after 3 failed attempts, so our SYSTEM account is getting locked.

The DBA_AUDIT_TRAIL table shows that the login attempts are coming from OS_USERNAME "SYSTEM", USERNAME "SYSTEM", and the USERHOST is the computer on which the ORACLE DB is installed. I have looked at Oracle scheduled jobs and Windows scheduled jobs and not found any suspects.

The COMMENT_TEXT for the activity that is locking our databases says:

Authenticated by: DATABASE; Client address: (ADDRESS=(PROTOCOL=tcp)(HOST=XXX.XX.XX.XXX)(PORT=XXXXX))

Howdy, Stranger!
