Setting default values for the FABJMAIN program

The IMS HP Image Copy Site Default Generation utility enables you to set your own default values for the GLOBAL statement of the ICEIN data set.

The Site Default Generation utility creates a user site default table for the IMS HP Image Copy GLOBAL statement, and this table is used in every IMS HP Image Copy run. The input specification in the Site Default Generation utility is the same as the GLOBAL statement in ICEIN DD. The generated site default table is used by stand-alone IMS HP Image Copy and also by the IMS HP Image Copy process that is invoked by other IMS Tools products.

The Site Default Generation utility analyzes ICEIN GLOBAL statements and generates a source code for the site default table. To use the site default table, the library for the site default table module (FABJGLB0) must be concatenated to the STEPLIB DD of FABJMAIN runtime JCL.

If FABJMAIN finds the name FABJGLB0 in the STEPLIB libraries, IMS HP Image Copy loads the module and uses the values as default values for the GLOBAL statement.

If you specify a value in the GLOBAL statement of ICEIN DD, you can override the site default value at run time. When the GLOBAL statement is specified in the ICEIN DD of the runtime JCL, the value of the GLOBAL statement is used.

The following figure shows the process flow for creating and using the GLOBAL site default table.
