Global options modules—Prefix Resolution/Update function
You can specify options for the Prefix Resolution/Update function at the levels shown in the following table.
Module | Used for | Resides in | Created by |
|---|---|---|---|
Internal defaults | All jobs that don’t specify an options module or options in PLUSIN | N/A | N/A |
PRPPARMS | All jobs at your installation | Load library | ISPF panels or #DBUGLBL batch job |
PRP@imsi | All jobs run on a particular IMS system (for example, a test system) | Load library | ISPF panels or #DBUGLBL batch job |
DFLT member of PDX | All jobs, all jobs run on a particular IMS system, or all jobs for a particular database, depending on how the options module was created | PDX | An earlier release of the product |
dbdname member of PDX | All jobs for a particular database | PDX member | ISPF panels |
DLIGSET0 | All jobs at your installation | Load library | #DLIGLBL batch job (set it via PRP_#### keywords where it takes two values. First is a Y/N specifying if this override is chosen, and the second being the value itself. |
PLUSIN | The job where the options are specified | JCL | Adding keywords to PLUSIN control statement data set in reload job |
You can combine the global options module, the PDX options member, and command methods for specifying options for maximum efficiency. You can use the PRPPARMS options module to specify the values you want to use for most of the databases at your site. For particular keywords you want to use only on a single IMS system (for example, a test system), you can use the PRP@imsi options module. For databases that need values different from those you specified in the PRPPARMS or PRP@imsi modules, you can create a PDX options member for those DBDs. For jobs that require values different from those you usually use for the database, you can specify the values in the PLUSIN data set.
