Redirect JVM Output from .out to .log files in Weblogic

Just add


-Dweblogic.log.RedirectStdoutToServerLogEnabled=true

server start parameters ..
This will put JVM outputs (other than internal stuff like thread dump etc.) to .out file with level "NOTIFICATION"

Weblogic boot.properties

To avoid weblogic asking username-password for every server boot, create file boot.properties in /middleware/user_projects/domains/YourDomain/servers/YourServer/security

boot.properties file is like:

username=weblogic
password=weblogicpassword

weblogic corrupts some folders after disk gets full

weblogic can get dirty and corrupt some of its folders after a disk full error of OS. One thing is Adminserver stalls and does not restart. If this is the case, one possible solution is to delete the "ldap" folder under user_projects/domains/yourdomain/servers/AdminServer/data/

It can also corrupt upload folders of Adminserver. If you see errors like
Unable to access the selected application
Exception in AppMerge flows' progression

in deployment console while installing ears from upload folders, this can be solved by deleting respective upload folder, recreating it and copying ear files back. then install.
