WebLogic 11g start and stop automation

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 domain creation, 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 implement it). 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.
