Force Shutdown of weblogic in OBIEE 11G when services started

Solution :

Navigate to “boot.properties”  and change with your new password as below.
Admin Server boot.properties path :<BIEE_HOME>\user_projects\domains\bifoundation_domain\servers\AdminServer\security

Note : The User name and Password is already in encrypted format , just remove that and change the entry .
password=welcome1234
username=weblogic

Similarly do the same for bi_server1

If you do not find the bi_server ,then please create a folder as bi-server

BI Server boot.properties path:
 <BIEE_HOME>\user_projects\domains\bifoundation_domain\servers\bi_server1\security
password=welcome1234
username=weblogic

Save these files and start the services again. You should be able to start the server

In such cases there is another alternative go to the config. xml location in the Path folder location
OBIEE_HOME\user_projects\domains\bifoundation_domain\servers\domain_bak\config_prev
