This configuration brings a fixed known value to the logging disk usage of the entire domain.

WebLogic Server does not provide an out of the box configuration to rotate the standard
output log ( $DOMAIN_HOME/servers/PROD_ServerXX/PROD_ServerXX.out ). As a
workaround, STDOUT and STDERR from the PROD_ServerXX.out file were redirected
to the server log and disabled. This configuration maintains the information of the
PROD_ServerXX.out file in the PROD_ServerXX.log file.
