Weblogic Start All Managed Servers WLST Script

The Objective

In this post, we are going to share the WLST jython script we have created to start all the managed servers in the weblogic domain. To be more precise, The Script will start the servers which are not already started or down from the specific weblogic domain.

Once started, The Scripts working architecture can be denoted like this

1. Connects to AdminServer
2. Print the Status of the servers in the domain
3. Starts the server which is currently down or not running.

How to Use this Script?:

1. Copy the following source code to your terminal and save it as a .py file
2. Set the Environment using ./setDomainEnv.sh or ./setWLSEnv.sh
3. Invoke the script with WLST with the following startup arguments (or) options
   1. username (or) key file
   2. password (or) config file
   3. Domain Admin URL

The WLST Script to start all managed servers

	connect(USERNAME, PASSWORD, ADMINURL)

	toprint = '''
