How to reset the Weblogic admin server password

In some case we need to change the weblogic password, and then we can follow the below steps to reset it.

Step 1:

Set the following environment variables (update the domain name    as appropriate):

export FMW_HOME=/u01/app/oracle/product/middleware
export DOMAIN_HOME=$FMW_HOME/user_projects/domains/
export CLASSPATH=$CLASSPATH:$MW_HOME/wlserver_10.3/server/lib/weblogic.jar

NOw we will run the env as shown below.
. $DOMAIN_HOME/bin/setDomainEnv.sh

Step 2:

Need to shut down weblogic domain:
$DOMAIN_HOME/bin/stopWebLogic.sh

Step 3:

Rename and backup the DefaultAuthenticatorInit.ldift file as shown below,

cd $DOMAIN_HOME/security
mv DefaultAuthenticatorInit.ldift DefaultAuthenticatorInit.ldift.old

Now run the following command to generate a new DefaultAuthenticatorInit.ldift file. ((here ‘weblogic’ is default username))

java weblogic.security.utils.AdminAccount .

Note: Don't forget the period "." at the end of the this command, otherwise you will get "Error: Invalid arguments"

Rename and backup the following LDAP directory.

mv $DOMAIN_HOME/servers/AdminServer/data/ldap $DOMAIN_HOME/servers/AdminServer/data/ldap.old
(This ldap directory will be recreated once weblogic server startup time)

Step 4:

Back and Edit the boot.properties file and update the new password. (Above new_password)

cd $DOMAIN_HOME/servers/AdminServer/security
cp boot.properties  boot.properties_old

vi boot.properties
password=
username=

(Note: New password will be encrypted once server starts)

Step 5:

Now start your weblogic domain.

[oracle@appserver01 bin]# cd /root/MW_home/user_projects/domains/base_domain/bin/
[oracle@appserver01 bin]# ls
nodemanager  nohup.out  server_migration  service_migration  setDomainEnv.sh 
startManagedWebLogic.sh  startWebLogic.sh  stopManagedWebLogic.sh  stopWebLogic.sh
[oracle@appserver01 bin]# nohup ./startWebLogic.sh &
[oracle@appserver01 bin]# nohup: appending output to `nohup.out'
[oracle@appserver01 bin]# tail -f nohup.out 

Server state during the startup:
 
 
 
 
 
 

Now we can access your weblogic console page.
