Art of BI: Oracle 11g RDBMS Password Expiration Default – Possible Impact on OBI 11g

The Oracle 11g db seems to default to expiring a user’s password within a fairly short window.  Recently I was testing an old OBI 11g VM I had put together and when the Weblogic services didn’t start up properly the investigation and troubleshooting phase began.  Since the Weblogic and OBI 11g components rely on the two schemas for MDS and BIPlatform if a connection cannot be made to these schemas for any reason unexpected results will occur for your OBI 11g implementation. Ultimately the resolve was to update the user account with an unlimited password lifetime grant similar to the PL/SQL code below.  This code below simply sets the default profile with which a user/schema may be associated.

ALTER PROFILE DEFAULT LIMIT
  FAILED_LOGIN_ATTEMPTS UNLIMITED
  PASSWORD_LIFE_TIME UNLIMITED;
