Customizing after installation

You can set up various levels of customization to suit your needs.

Customization helps you obtain maximum flexibility when processing an Image Copy utility task.

You can use three methods of customization:

• Global options modules

• Database-specific options modules (These are actually members in the PDX.)

• Customization keywords on the control statements in the ICPSYSIN data set

The reasons you select one method of customization over another depend on how your databases and IMS systems are set up.

Example

A company has just decided to implement the Image Copy utility. After looking through the internal defaults, a database administrator determines that the installation would require different default values from the ones supplied with the utility. First, the installation name printed on reports must be changed from BMC SOFTWARE, INC., the default, to the actual name of the company. Second, the company is running two different IMS systems. One is a test system, and one is a production system. The database administrator has decided to compress all output image copy data sets in the production system, but leave the image copy data sets expanded in the test system. The only exception is one large database in the test system. The output image copy data sets for this database should also be compressed.

With this example in mind, refer to Deciding which customization method to use for information about selecting a method.
