Customizing the FM/IMS installation options module

Before you can use FM/IMS, you must customize the installation options module, FMN1POPT. In FMN1POPT you specify:
  • The IDs of the IMS™ subsystems that are to be accessed by FM/IMS.
  • The parameters that are to be passed to the IMS™ region controller when a function starts a BMP, Fast Path or DL/I batch processing region.
  • The names of the PSBLIB, DBDLIB, DFSVSAMP, RESLIB, IMS™ macros, staging ACBLIB, RECON, DOPT ACBLIB and Template data sets for each subsystem.
  • Selected processing options that you want the FM/IMS functions to use.
  • Whether or not the user can override the values you specify for selected parameters, data sets, and processing options.

A version of FMN1POPT is distributed with FM/IMS, but you will need to replace this module with your own version of FMN1POPT.

You use the usermod FMN1UMDP to install your version of FMN1POPT. FMN1UMDP and the source for FMN1POPT are distributed in FMN.SFMNSAM1. To create and install your own version of FMN1POPT:

  1. Copy the member FMN1POPT from FMN.SFMNSAM1 into your own source library. The member FMN1POPT contains the sample source for the FMN1POPT module.
  2. Modify your copy of the FMN1POPT sample source, as described in the following sections.
  3. Modify the FMN1UMDP member in FMN.SFMNSAM1 to meet your site's requirements. Refer to the usermod for information about changes you might need to make.
  4. Install SMP/E usermod FMN1UMDP.
Note: You can also use the sample job FMN1POPH to assemble FMN1POPT if you do not want to use SMP/E.
