Preloading HCL Integration Platform maps and .mdq files in a z/OS CICS environment

The CICS® preloader utility preloads HCL Integration Platform maps and database query (.mdq) files into memory. When maps and .mdq files run frequently, you can reduce processing by preloading them into memory. Preloaded files do not require I/O processing.

The CICS preloader loads maps and .mdq files from a partitioned data set (PDS or PDSE) or from a z/OS® flat file.
