Solution:

Step 1: Go into your DOMAIN_HOME\bin.

Step 2: Execute the script :  . ./setDomainEnv.sh

Step 3: Run  java weblogic.security.Encrypt username where username is the Admin user.

Step 4: Run java weblogic.security.Encrypt password where password is the admin user <PASSWORD>.

Step 5: Edit the boot.properties file located at DOMAIN_HOME/servers/AdminServer/security/boot.properties and it has the syntax mentioned below:

username=<USERNAME>
password=<PASSWORD>

Step 6: Replace with the <PASSWORD> with the encrypted value from output steps 3-4.  If  boot.properties file includes any other lines, remove them.

Step 7: Start the BI services and test by logging into WLS console.
