Start Weblogic without user and password

When you want to launch your weblogic server at production, you need to use the startWeblogic.sh in your bin folder.

But each time it's launched it's asking you to authenticate yourself by typing a user and password. It's a problem when you want to automate the execution of your server...

To avoid this problem all you need to do is creating a file named "boot.properties" and insert into the two following lines :

username=<yourUserName>
password=<yourPassword>

this file must be placed in each server security folder : $WLS_HOME/user_projects/domains/<domainName/servers/<serverName>/security

Then, start server, it shouldn't ask you for anythin, then reopen your boot.properties file, password and username should be automatically encrypted !

Avoid java out of memory with Weblogic

This is common exception always exists if you install weblogic and doesn't extend memory arguments in server.

The file "setDomainEnv.sh" in $WLS_HOME/user_projects/domains/<domainName>/bin/ has configuration of domain.

If you edit this file it will have the following default values.

MEM_ARGS="-Xms256m -Xmx512m"

export MEM_ARGS

MEM_PERM_SIZE="-XX:PermSize=48m"

export MEM_PERM_SIZE

MEM_MAX_PERM_SIZE="-XX:MaxPermSize=128m"

export MEM_MAX_PERM_SIZE

you should modify the MEM_ARGS java memory value depending of your server, here is the suggested to increase.

MEM_ARGS="-Xms2024m -Xmx3036m"

export MEM_ARGS

MEM_PERM_SIZE="-XX:PermSize=128m"

export MEM_PERM_SIZE

MEM_MAX_PERM_SIZE="-XX:MaxPermSize=512m"

export MEM_MAX_PERM_SIZE

Note : choosing the values depend on you server hardware.

Thanks
