64-Bit Memory

CA WA CA 7 Edition now allocates and manages 64-bit memory for use by its applications. Queue processing is the main user of this service as all of its in-core tables are now in 64-bit storage. The scratch work files are also now kept in 64-bit storage. The following pools are defined:

Queue Header Table (QHT)

• One entry for each CA 7 job number.
• Queue header data and some trailer data for active jobs.

Status Queue Table (SQT)

• One table per status queue (PRE, REQ, RDY, ACT, and PST).
• One entry per job in the related queue.

General pool

• Default size can be specified in the new optional INIT file statement RESIDENT,G64PL=size in MBs. The default is 15360, which is 15-GB.
• Used for scratch work files.

JCL pool

• JCL, cross platform PARMLIB data, and network reminder text for active jobs and networks.

Miscellaneous pool

• Input requirements, output trailers, #SCC input data, # SCC output data, load data, and network headers for active jobs.
