Local Installations

For the local installation, CA Gen compiles the generated source and link-edits the load modules. The binder control cards that are used in link edit are stored in Binder Control Cards library.

CA Gen local installation link-edits the dynamic action blocks including z/OS Library modules for batch processing in addition to regular link edit if Executable Batch Dynamic Action Block library is specified for the Business System.

For z/OS Libraries, the online version of z/OS Library DLL is populated in the regular Executable Load Modules Library. The batch version of z/OS Library is saved in the Executable Batch Dynamic Action Block library if specified. DB2 attachment type for batch z/OS Library DLLs is as specified by the TIRDBATT parameter, defaulting to DSN.

For dynamic action blocks, if the Executable Batch Dynamic Action Block library is specified, it contain the batch versions of dynamic action blocks. The following rules apply if this library is present.

• Dynamic action block that is linked via the caller batch load module:
  • Batch version of the dynamic action block is populated in Executable Batch Dynamic Action Block library.
• Dynamic action block that is linked via the caller non-batch load module:
  • Non-batch version of the dynamic action block is populated in the regular Executable Load Modules Library.
  • Batch version of dynamic action block is prepared and populated in the Executable Batch Dynamic Action Block library.
• If the batch library is not specified, then the Executable Load Modules Library contain the most recently installed dynamic action block, which have batch or non-batch runtimes. It is recommended to specify the Executable Batch Dynamic Action Block library in this case.

Important! Do not give the Executable Batch Dynamic Action Block Library the same library name as the Executable Load Modules Library.

If your environment permits, CA Gen also executes the DB2 bind that is required for programs that use DB2 databases.
