Set $

puts "About to dump threads for this jvm..."

$AdminControl invoke $jvm dumpThreads

puts "... done"

------------

Invoke the generateHeapDump operation on a JVM MBean, for example,

Finding JVM objectName:

set objectName [$AdminControl queryNames

WebSphere:type=JVM,process=<servername>,node=<nodename>,*]

Invoking the generateHeapDump operation on JVM MBean:

$AdminControl invoke $objectName generateHeapDump

Ex: wsadmin -f test.py a b c

test.py content:

import sys

first = sys.argv[0]

second = sys.argv[1]

third = sys.argv[2]

arglen = len(sys.argv)

16)In Jython script how to invoke a variable which was defined in another jython script?

Using MBeans

Calling scripts using another script

Use the execfile command to call a Jython script from another Jython script. For example:

Create a script called test1.py that contains the following:

execfile('c:/temp/script/testFunctions.py')

print printName('Cathy', 'Smith')

Create a script called testFunctions.py that contains the following:

def printName(first, last):

name = first + ' ' + last

return name

Then pass the following path as a script argument:

wsadmin -lang jython -f 'c:/temp/script/test1.py’
