Before You Use Agent Builder

Before you use Agent Builder, you need to know how to create resource types with multiple independent process trees.

Agent Builder can create resource types for applications that have more than one independent process tree. These process trees are independent in the sense that the PMF monitors and starts them individually. The PMF starts each process tree with its own tag.

Note - Agent Builder enables you to create resource types with multiple independent process trees only if the generated source code that you specify is C or GDS. You cannot use Agent Builder to create these resource types for the Korn shell. To create these resource types for the Korn shell, you must manually write the code.

In the case of a base application with multiple independent process trees, you cannot specify a single command line to start the application. Rather, you must create a text file, with each line specifying the full path to a command to start one of the application's process trees. This file must not contain any empty lines. You specify this text file in the Start Command text field on the Agent Builder Configure screen.

Ensuring that this file does not have execute permissions enables Agent Builder to distinguish this file. The purpose of this file is to start multiple process trees from a simple executable script that contains multiple commands. If this text file is given execute permissions, the resources come up with no problems or errors on a cluster. However, all the commands are started under one PMF tag. As a result, the PMF is unable to monitor and restart the process trees individually.
