You have no indentation in your Python code!
def datasource(cluster,user,password,url,env,jdbc_driver,timeOut,maxConn,minConn,reapTime,unusdTimeout,agedTimeout):
    #Declare global variables 
    global    AdminConfig 
    global    AdminControl
Fixing this, there will be others. The next one to fix is:
if len(Serverid) == 0:
    print "Cluster doesnot exists "    
else:    
    print "Cluster exist:"+ cluster
and so on.
