Today, Chris Giddings one of our subscriber asked us by commenting if we have any automated script which can start the Admin Server as they have this type of requirement and the script should not take much load too on there system. So seeing the requirement we took out sometime and wrote a WLST script which can do that job for Chris and hope that this script would also help our other subscribers too.

The logic behind this WLST script is that first this script would start the NodeMnager, then the script would connect to NodeMnager and then it would also start the Admin Server. So in short this script would do three things in no time without much load and just by changing few things in the property file called domains.properties as per your environment which has all the details about the domains and the server which has to started.

Note:

- Make sure you associate a Machine for the Admin Server
- Make sure you keep both this files (i.e. domains.properties and Start_Admin.py) in the same folder when you are running the script or else you would have to give the path.
- Also this script would create nm_data.properties, nodemanager.log and nodemanager.properties if they are not present in the directory from where you are running the script.
- This script does not use SSL, so you would have to first start the adminserver using startWebLogic.sh first, then go to the Admin Console path

Environment –> Machines –> [YOUR_MACHINE_NAME] –> Configuration [tab] –> Node Manager [sub-tab]

Type = Plain

- Following is the nodemanager.properties which we had used you can notice that SecureListener=false as we not using SSL and StartScriptEnabled=true because we had got OutOfMemory: PermGen error so by doing this the memory parameters would be picked up by  startWebLogic.sh

Steps to Start AdminServer And NodeManager Using WLST

1. Below is the details which domains.properties would have

username=weblogic
password=weblogic
host=localhost
nm.port=5556
domain.name=Domain_7001
domain.dir=/WLS103/user_projects/domains/Domain_7001
nm.type=plain
server.name=AdminServer

2. And below is the WLST python script Start_Admin.py which would call the above properties.

from java.io import FileInputStream
import java.lang
import os
import string

propInputStream = FileInputStream("domain.properties")
configProps = Properties()
configProps.load(propInputStream)

Username = configProps.get("username")
Password = configProps.get("password")
Host = configProps.get("host")
nmPort = configProps.get("nm.port")
domainName = configProps.get("domain.name")
domainDir = configProps.get("domain.dir")
nmType = configProps.get("nm.type")

startNodeManager()
print ''
print '============================================='
print ' NODE MANAGER started Successfully...!!!'
print '============================================='
print ''
nmConnect(Username,Password,Host,nmPort,domainName,domainDir,nmType)
print ''
print '============================================='
print 'Connected to NODE MANAGER Successfully...!!!'
print '============================================='
print ''

serverName = configProps.get("server.name")
print '###### serverName = ', serverName
nmStart(serverName)
serverName = configProps.get("server.name")
print ''
print '============================================='
print '===> Successfully started ', serverName, '  <==='
print '============================================='
print ''

3 . Following would be the output as soon as you run the Start_Admin.py using the below command

Command:


java weblogic.WLST Start_Admin.py

Output:


D:\Oracle\Test App\Domain>java weblogic.WLST Start_Admin.py
