As you know, Weblogic is a part of the Enterprise Manager Cloud Control environment, and it’s automatically installed and configured by the EM installer. The Enterprise Manager asks you to enter a username and password for Weblogic administration. This information is stored in secure files; you usually do not need them unless you use the Weblogic console. So it’s easy to forget this username and password, and that’s what happened to me. Fortunately, there’s a way to recover them without resetting a new user/password. Here are the steps:
First, we need to know the DOMAIN_HOME directory. My OMS is located in “/u02/Middleware/oms”. You can find yours if you read “/etc/oragchomelist”. If the full path of OMS is “/u02/Middleware/oms”, the middleware home is “/u02/Middleware/”. Under my middleware home, I need to go GCDomains folder:
oracle@db-cloud /$ cd /u02/Middleware
oracle@db-cloud Middleware$ cd gc_inst/user_projects/domains/GCDomain
oracle@db-cloud GCDomain$ cat servers/EMGC_ADMINSERVER/security/boot.properties
