How to recover or reset weblogic console password

Steps to Reset the password for Weblogic Admin Console

Step 1. Run setDomainEnv.cmd/setDomainEnv.sh from your %DOMAIN_HOME%/bin directory to set necessary domain environment variables in command prompt for windows and shell prompt for Unix as above tool requires weblogic.jar to run.

Note: Any information below should be updated to match your directory structures and information

       %DOMAIN_HOME% -  C:\bea10\user_projects\domains\weblogic_domain\bin

Step 2. Backup or rename the DefaultAuthenticatorInit.ldift file located under your %DOMAIN_HOME%/security directory as Step 3 creates a new DefaultAuthenticatorInit.ldift file with modification specified.

Step 3. From %DOMAIN_HOME%/security directory run the below command.

"java weblogic.security.utils.AdminAccount weblogic <new_passwd> ." 

Note: There is a . (DOT) at the end of the above command which represents the Current Directory. A new “DefaultAuthenticatorInit.ldift” file will be created after the command is executed in the current directory.

Step 4. Rename the data directory to data.bkp located under your %DOMAIN_HOME%/servers/AdminServer.

Step 5. Rename all the instances of boot.properties to boot.properties.bkp located under your %DOMAIN_HOME% [if any] and %DOMAIN_HOME%/servers/AdminServer/security directory.

Step 6. Create a new boot.properties with new password as below under %DOMAIN_HOME% [if any there was earlier] and %DOMAIN_HOME%/servers/AdminServer/security directory. As recommended to avoid prompting for Username and Password while starting the Weblogic instance this step is mandatory.

boot.properties

username=weblogic

password=<new_passwd>

Note: Make sure the boot.properties is not having any extra special characters (UTF or Invisible characters) or spaces except the above two lines. Also there should be no Heading or Trailing SPACE character in these two Lines.

Step 7. Issue a Startup command to Weblogic instance and monitor the logs. If you are using Windows service for startup of Weblogic then you might also need to delete the existing windows service and install the windows service with new credentials. Please refer WebLogic Server instance as Windows Service .

Step 8. Your managed servers also needs to be started with new boot.properties. You can follow step4 to step7 or just replace all the instances of boot.properties on your managed servers with the one on AdminServer and rename the servers directory located under %DOMAIN_HOME% on managed servers. 

Step 9. Login to the console with the new password.
