Leave a Comment / By Yogesh / March 27, 2019

Given a weblogic server.
We would like to get list of running servers in current domain using python script.
We would following the trailing steps to get list of active servers (WLST).
- Connect to admin server using t3 protocol.
- Get list of all servers (RUNNING, SHUTDOWN, STARTING etc) in current domain.
- Loop through all servers to filter out RUNNING servers.
- Disconnect from admin server

List of running servers in weblogic domain (WLST /example)

def runningServers():
 
    #Get list of servers in current domain
    servers = cmo.getServers()
    domainRuntime()
    
    print "List of running servers in current domain: "
    for server in servers:
        cd("/ServerLifeCycleRuntimes/" + server.getName())
        state = cmo.getState()
        if state == "RUNNING":
            print server.getName()
    print "End of script"
 
connect("weblogic","welcome2","myAdminServer:7001")
 
runningServers()
 
disconnect()
