Specifying discovered resources by using sample configuration members

The z/OS® DLA includes the following sample configuration members that you can use to specify which resources are discovered:

IZDCDEF: Default DLA configuration parameter deck in IZDPDISC JCL PROC.
This configuration parameter deck includes all configuration settings that control which resource types are included in books, and the type of books to create. As a result of default configuration settings, or any configuration overrides a customer specifies in IZDCDEF, resources are then written out to books (CICS®, IMS, DB2®, MQ, and WebSphere®). The IZDCDEF parameter deck excludes some potentially high volume resources, for example, transactions, programs, and databases.
IZDCBASE: DLA configuration parameter deck to discover ZOSBASE only.
IZDCTASK: DLA configuration parameter deck to discover ZOSTASK only.

All books have an MSSName attribute that identifies the “author” of the book. The MSSName includes the member name and fully qualified host name. This enables a refresh to be performed per subsystem independent of whether other subsystems are active or inactive.

By having separate books, checksum comparisons can be made against previous discoveries, which avoids having to transfer books to the DLFS that have not changed since the previous discovery. For more details, see the FTP section.
