EGL Server Guide for iSeries


Understanding preparation

This section describes the preparation process for a generated application to run in the iSeries environment. The preparation process is significantly different from that used in VisualAge(R) Generator.

The preparation is accomplished by using the iSeries Remote Build Server, which is a component of the EGL run time. For details, see Starting the iSeries Remote Build Server.

When an application is generated, an xml file, called the Build Plan, is created in the generation directory. The build plan is launched to prepare the application on iSeries, using a Java program called the build plan launcher.

When the application is generated with the build descriptor option prep set to yes, the build plan is launched automatically at the end of the generation. Otherwise the build plan can be launched later manually by following the process described later in this document.

The Build Plan Launcher uses the build plan and communicates with the Build Server to accomplish the preparation. The build plan contains all the information necessary to transfer the applicable generated files to iSeries and to build (compile and bind) the application.

A key component of the preparation is the Preparation Script. This is a Rexx Script, FDAPREP, which is installed as part of the runtime code and is described in iSeries preparation script file FDAPREP.
