Load Libraries and Maintenance Libraries

Separately installed FOCUS components are delivered in paired sets of libraries: a load library, and possibly other libraries needed for execution, and a maintenance library. The maintenance library is not needed for execution, but contains whatever is needed to install the component and maintain its load library. The contents of these libraries may vary from release to release and it is critical that you retain the association between load libraries for given releases and their corresponding maintenance libraries. To do this you must follow the data set naming conventions described in Features and Components.

The following table shows the standard names of the FOCUS libraries, including the Data Adapter libraries that have their own associated installation guides. You will find that FOCUS is easy to maintain if you retain these data set names, with only the high-level prefixes added to differentiate between releases.

For historical reasons, the maintenance library of FOCLIB.LOAD is called FOCCTL.DATA rather than FOCLIB.DATA. For all other separately installed components, the load library has the suffix LOAD and its maintenance library has the same name with the low-order suffix DATA.
