Configure JVM heap for WAS cluster members

Nice and simple if you have many JVM's in your cluster.
Note the wildcard feature when listing AdminConfig types (Line 24), very handy.

def getJvms(clusterName):
        # Get the cluster ID
        cluster = AdminConfig.list('ServerCluster', '*'+clusterName+'*')

        # Get a list of the clusters members
        members = AdminConfig.showAttribute(cluster, 'members')
        memberArray = members.split('[')[1].split(']')[0].split(' ')

        # Detemine JVM's
        jvms = []
        for member in memberArray:
                memberName = AdminConfig.showAttribute(member, 'memberName')
                jvms.append(AdminConfig.list('JavaVirtualMachine', '*'+memberName+'*'))
        return jvms

 

def setHeap(jvms, min, max):
        for jvm in jvms:
                print 'Setting '+jvm+' heap sizes of '+str(min)+' and '+str(max)
                AdminConfig.modify(jvm, [['initialHeapSize', min]])
                AdminConfig.modify(jvm, [['maximumHeapSize', max]])

setHeap(jvms, min, max)
