Introduction to build parts

Build parts control the generation process and set how an application will behave at run time. The kinds of build parts you need vary depending on the target platform of your application and the type of application that you have created.
Build descriptor part
A build descriptor part controls the generation process and indicates what other control parts are read during that process. Build descriptor parts contain build descriptor options, which are covered in the EGL Generation Guide. The information in this part is used at generation time, test time, and run time.
Linkage options part
A linkage options part gives details on how a generated program calls or transfers to and from other programs. The part also gives details on how a generated COBOL program accesses files on remote CICS® regions. The information in this part is used at generation time, test time, and run time.
Resource associations part
A resource associations part relates an EGL record with the information that is needed to access a file on a particular target platform; the information in this part is used at generation time, test time, and run time.
Bind control part
A bind control part (which applies only when the target platform is z/OS®) describes how to access a DB2® database from one or more programs. The information in this part is used at generation time and preparation time.
Link edit part
A link edit part (which applies only when the target platform is z/OS) describes how to form a load module from two or more programs. The information in this part is used at generation time and preparation time.
Deployment descriptors
EGL deployment descriptors are not build parts, but they fit into the category of files involved in generation and deployment. Deployment descriptors contain information that describes either how a service part from your application is exposed to other applications or how an external service will be used in your application. For more information, see “Introduction to EGL generation and deployment.”

More information on build parts is available in the EGL Generation Guide.
