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.
To find out how much space you require:
- Review the sizes of the modules that you want to install in the MVS link pack area, as given in the load library directory information.
- Review the module index of a system dump for the CICS region started with the system initialization parameter LPA=NO.
- Calculate the module sizes that are given for each module in the listing of modules that is provided by the IEHLIST utility program.
Remember also to allow space for any of your user application programs that you intend using from the MVS link pack area. The total space required depends on how the operating system packages the modules into the MVS link pack area.
When you have determined the space you require in the MVS link pack area, create a library with enough space and define it to your MVS. See Defining the CICS LPA library to your MVS for more information.
