I'm following a training intensive 5 days course for Oracle WebLogic. Some of exercises included stopping / starting Weblogic App server for security reasons Weblogic is designed to always propmpt for password. I remember similar behavior in Apache configured to use SSL certificate.
Whether a new Weblogic server is configured and a frequent restart of server is needed having to write the password each and everyime is mostly annoying. Thanksfully there is a file called boot.properties in which username / password can be hardcoded and later red on Weblogic start. As boot.properties contains security credentials its very important to keep the file as secured as possible. boot.properties files can be set-up for each different configured separate Weblogic server instance.
For my training sessiion boot.properties is in locations:
# cat /home/oracle/wls11g_advadm/work/domains/MedRecDomain/servers/MedRecSvr2/security/boot.properties
Depending on how Oracle Weblogic is configured its possible values in boot.properties (username / password) to be encrypted after first server boot-up.
