Reset/Change the ias_admin password

While upgrading the grid control host, I ran into a bug, when I say bug in this instance I mean a user problem, not the usual Oracle bug.

Apparently the ias_admin password had been changed and no one remembered to record the new password.

Oracle as usual makes life easy for us by not having any documented procedure for changing the password if forgotten.

There are two ways to change the password but no "official" way to change it if you forgot/lost the password.

After a huge amount of troubleshooting and research (15 minutes). I found this hack. The only problem is that it stores your password in clear text. Proceed at your peril:

Change ias_admin password directly in configuration file
–Backup $ORACLE_HOME/sysman/j2ee/config/jazn-data.xml
–Search for entry like below

  <user>
    <name>ias_admin</name>
      <credentials>{903}8QkQ/crno3lX0f3+67dj6WxW9KJMXaCu</credentials>
  </user>

change password like below 

  <user>
    <name>ias_admin</name>
      <credentials>Password</credentials>
  </user>
