Everytime I work on new project there is a need of creation of the clustered domain. From my past experiences collected all basic requirements together list them over here.
- AdminServer configuration includes Name, Listen Address, ListenPort
- User credentials username, password
- After writing basic domain going for create machine which include Name, type of machine
- Nodemaager includes NMTypes such as plain, ssl, hosted node, nodemanager port
- Managed servers have Name, ListenAddress, ListenPort, set machine
- Cluster includes name, ClusterAddress, Servers part of the cluster interesting part here
Assumptions for this task:
In the script as per my convenience some of them are hardcoded, My hardcoded values:

| WLST Configuring WebLogic Cluster Domain |
In the script as per my convenience some of them are hardcoded, My hardcoded values:
- Managed Server list
- Cluster list
In this script lots of Python sequence functions are used.
Lets begin the fun of WLST HERE...
- List index,
- Dictionary keys
- String startwith
Lets begin the fun of WLST HERE...
# purpose: Create the domian with the one Admin Server along with the
# two managed servers in each cluster. app_cluster, web_cluster
# Assumption here all managed servers runs on the same machine
# Modified date: 07-April-2017
# File name : create_clusterdomain.py
# Dependencies : cluster_domain.properties
# Note this names of managed servers, cluster, hostname all hard coded

Now the properties file which you can enhance with your limitations
WLSAdminIP=192.168.33.100 AdminPort=8001 AdminPasswd=welcome1 DomainPath=/u01/app/oracle/domains DomainName=uat_domain
Lets have the execution screen for you:
Please write your valuable feedback on this post, so that we can keep improve further to have more interesting fun stuff soon for you.
