Nodemanager Init.d Script
- by john.graves(at)oracle.com
I’ve seen many of these floating around. This is my favourite on an Ubuntu based machine. Just throw it into the /etc/init.d directory and update the following lines: export MW_HOME=/opt/app/wls10.3.4 user='weblogic' Then run: update-rc.d nodemanager default Everything else should be ok for 10.3.4. #!/bin/sh
#

# The setWLSEnv.sh not only does a good job of setting the environment,
