Grid Control & OID: a deadly combo

If you ever experience these symptoms, ask your self whether you have Grid Control (or OEM) running.

• Single Sign On fails
• OID Processes suddenly have stopped (which explains the above)
  
• ODS database account is locked, which seems to cause the problem
• Unlocking the ODS account resolves the problem, but it gets locked after a short period.

The cause is the fact you changed the ODS password. Now, you may have done this quite correctly by using the oidpasswd utility, ensuring the wallet gets updated, etc, but that does not update targets.xml... This means, Grid Control (or OEM) periodically tries to log on with the wrong password.

One solution is to update the ldap section of $ORACLE_HOME/sysman/emd/targets.xml, and update the password in plain text (and signal it is no longer encrypted by means of: ENCRYPTED="FALSE").
Then, restart Grid Control (or OEM)
