In a normal installation the weblogic user resides in the WLS-embedded LDAP so you can manage his password through the WLS console.
Security Realms -> myrealm -> Users and Groups -> Users -> query for weblogic -> Passwords
If you do that be advised to verify all other places the old password may be in use! Example: credential store, boot.properties...
Please follow the below steps.
IF YOU KNOW CURRENT PASSWORD
- Start the Admin Server and log into console.
- Go to page: Home > Summary of Security Realms > myrealm > Users and Groups > weblogic. and click on tab Passwords.
- Enter the new Password.
- Restart the server.
If you get a weblogic.security.SecurityInitializationException error, perform these additional steps on every Managed Server (or eventually the Admin Server, too):
- Go to folder DOMAIN_HOME/servers/AdminServer/security
- Edit the boot.properties file and change the password to the value already entered on the Admin Console. Do this for all the servers in the domain.
- Start the Admin Server (Weblogic Server will encrypt the password for you).
Basically you're +1'ing what was already written in the thread?
Restart all servers or just OPMN restart would be enough in Step 4?
Also i am not able to see boot.properties file in following path:/u02/OBI_MWH/user_projects/domains/bifoundation_domain.
1. restart of all the servers is necessary ( AdminServer, bi_server1 and opmnctl)
2. you can create a boot.properties file inside DOMAIN_HOME/AdminServer/security in case it does not exist and on DOMAIN_HOME/bi_server1/security as well.
