When installing a new WebLogic Domain for any a-specific Oracle (Fusion) Middleware application or any other implementation requiring a WebLogic domain like ORDS for instance, a new ‘home’ is created under [MW-home]/user_domains/. [MW-Home] translates, for instance, to /u01/oracle/product/Middleware.
To start your brand-new domain, or perhaps and rather, to automate the startup of your domain, you would use the supplied [MW-home]/user_domains/[DomainName]/startWebLogic.sh command-file.
This file will start the Weblogic domain (the Admin Server) and the deployed components. After this start, you will be able to follow through with the administration over the web-console. Typically its URL is: http://[ServerName]:[PortNumber]/console.
One nasty thing you can run into, is that starting the server can require you to enter username and password during the run of [MW-home]/user_domains/[DomainName]/startWebLogic.sh. Of course this is rather annoying because it requires interaction which is not good for auto-start. Regular input-tooling you can wrap around this command-file, for example with input redirection, would require you to save your username / password combination in plain text. That is certainly never a good idea!!
Luckily there is a trick to enable your WebLogic domain to start without this interaction. And it also makes sure that username & password are not stored in plain text. Actually it is quite easy to get this facility in place.
This is how:
Go to [MW-home]/user_domains/[DomainName]/Servers/AdminServer/security and create a plain text file called boot.properties.
This file gets two lines:
username: Your WebLogic Username
password: Your WebLogic Password
Basically, this is now a plain-text recording of the username and password on the server, which seems quite scary.
Good thing though, is that when you have successfully run [MW-home]/user_domains/[DomainName]/startWebLogic.sh command file, which will now continuously run through, username and password will be encrypted:
#Thu Mar 10 14:11:38 UTC 2016
You will now be able to call [MW-home]/user_domains/[DomainName]/startWebLogic.sh from your startup-script without having to worry about the need to interactively entering username / password or have to worry about plain text storage of these to artifacts.
Hope this helps!
