Sometimes you couldn’t remember the ias_admin password when accessing the Oracle Enterprise Manager (OEM), and you need to reset or change the password.
If you totally forgot your ias_admin password, then you need to login to your Unix box where the OEM was installed. Create a backup of your configuration files on $ORACLE_HOME/sysman/j2ee/config/jazn-data.xml.
After the backup was created, vi the $ORACLE_HOME/sysman/j2ee/config/jazn-data.xml files and search for entry like below
The current password was stored in an encrypted value and you can update new password to become blank by erasing the credentials value.
Please be aware that after you change the files, the OEM does not need to restarted.
If you restarted the OEM, the password will be change back to current password which you have forgotten.
Reset password to a blank password for ias_admin could lead to security issue as anyone can logon to your OEM with password.
Immediately after you have reset the password by changing the configuration files, login to Instance Home Page using Enterprise Manager (Application Server Control): –
– Click on Preferences on top right
– In the new screen, click on “Change Password” on left menu
– Enter Current password and New Password
This will set your ias_admin to have the new value password instead of blank password.
