WebLogic 11g start and stop automation

There are many ways of starting and stopping your Oracle WebLogic 11g ? environments, You can stop your Admin and Managed Server Instances through the Adminsitration console, use the the start and stop scripts shipped with the Oracle WebLogic software and domaincreation, or use a tool like WLST to manipulate your entire environment.

In this blog I will ? use the different kinds of techniques to stop and start your Oracle WebLogic Server environment, even in case of a physical host reboot (planned or unplanned)

For this I used the common UNIX shell scripting in combination with WLST

The bundle consists of the following components:

weblogic_rc.sh start|stop|status –> Overall shellscript which calls the different scripts for stopping and starting. This can be added to the bootsequence of the physical host, which varies per O/S ( Linux-init.d, AIX- rc) Ask you O/S admin how to implementit). Your OS profile needs to be set as well, so set some variables like MW_HOME. WL_DOMAIN and WL_DOMAIN_DIR, and ORACLE_HOME
nodemgrstart and nodemgrstop –> python/WLST scripts for starting the Node Manager. Can be invoked with or without the overall script. First set the setWLSEnv.sh or the setDomainEnv.sh to issue the correct environmentsettings. Execute:

java weblogic.WLST nodemanagerstart / nodemanagerstop

wl11gstart and wl11gstop > python/WLST scripts for starting the WebLogic Server Instances. Can be invoked with or without the overall script. First set the setWLSEnv.sh or the setDomainEnv.sh to issue the correct environmentsettings. Execute:

java weblogic.WLST wl11gstart / wl11gstop

See the scripts below:

weblogic_rc.sh:

#!/bin/sh
#
# Start and stop script for an entire Oracle FMW Forms 11g environment
# Tobe added to the rebootsequence of the AIX LPAR.
#
