Tivoli Field Guide - ITM Resource Model Development Guide
Volume 1: A Practical Use of the Shell Methods
White paper
Abstract
Shell is a method provided by the ITM engine’s Service object to allow resource model developers to execute scripts or binaries externally to the model itself. The use of this Shell method is very straightforward, which in its simplicity, can create confusion. Many implementers share the same common requirements for implementing the Shell method. That is, how do I pass parameters to my external script or executable and how do I receive more than one line from StdOut when my external task completes?
This document was created to demystify the use of the Shell methods for such requirements as well as to enlighten new resource model developers to the techniques that can be used to maximize the Shell results. This document is not intended to be a substitute for Visual Basic Script or JavaScript (Rhino) reference books and in fact, hopes to inspire would be developers to grab a coffee and one of the aforementioned texts.
