Installing CICS modules in the MVS link pack area

How to define the CICS® LPA library to your MVS™, and how to install and use the CICS modules.

Preparing to install CICS modules in the MVS link pack area
Before you install modules in the MVS link pack area, you need to understand the benefits, the scope, service level implications, and the modules required in the MVS link pack area.
Space requirements for CICS modules in the MVS link pack area
Allow enough space in the MVS link pack area for you to install those CICS modules that you intend using from there.
Defining the CICS LPA library to your MVS
CICS supplies the library hlq.SDFHLPA. This library contains the modules that must be in the LPA. You can also use this library to install other CICS modules or application programs that you want to use from the LPA.
Installing CICS modules in the LPA
You can install modules into the MVS link pack area by using SMP/E.
Controlling the use of modules from the MVS link pack area
Using customizable options, CICS allows you to control which of the eligible modules are executed from the MVS link pack area.
Sample DFHCSDUP job to specify USELPACOPY(YES)
The standard IBM-supplied program definitions in the CSD all specify USELPACOPY(NO). If you copy or move to the LPA the IBM® programs defined by definitions in the CSD, the next step is to modify the USELPACOPY attribute to ensure that CICS uses the LPA copy.
