The Application Parameter Manager facility lets you do the following tasks:
The Application Parameter Manager contains displayable, modifiable descriptions of each parameter.
When the CA OPS/MVS applications execute, they first fetch their parameters from global variables. These global variables are created from parameters in the database of the Application Parameter Manager on DASD. When a parameter value changes, the global variable containing the parameter must be updated with the new value. This updating is called parameter load.
The parameter administration interface allows you to look at the values loaded into global variables; it displays the current values. The parameter access module, a REXX program that automation applications call internally, locates the parameter value in global variable storage and returns the value to the application. The parameter access module also reads that value from the parameter database and loads it if it were not loaded earlier. You cannot alter the parameter access module.
You can view parameter descriptions and change default parameter values. CA-supplied edits (setting default field formats) are done on the parameter values after customization has finished.
The Application Parameter Manager contains default parameter values supplied by CA. Using the parameter administration interface, you can replace a customized parameter with the default value from CA.
