ZPWY-MAP- Definitions
The value you assign for this field depends on the number and the size of the
screen programs in your applications and also on the available swap space. Some
guidelines for this field are:
Use the size of the SCREEN COBOL programs (the screen data plus the
RUNUNIT SIZE listed for these programs compiled with MAP) that make up
the applications for this TCP. Note that not all of the screen programs are
executed all of the time and that the most regularly used programs determine
the amount of code space most often required.
Making this area slightly larger than necessary can prevent the TCP from
having to perform unnecessary code-fetching during TCP operation. The larger
code area only costs you disk space for the swap file.
After running the TCP with STATS ON, use the values returned from the
STATS TCP command and adjust the size of the code area to the actual value
required.
If you do not assign a value to this field, the default is 65,536 bytes.
ZCPUPAIR
specifies the primary and backup processor pairs in which the TCP processes run.
ZCPUPAIR can occur from 1 to 16 times.
ZPRIMARY
is a primary processor. Valid values are in the range from 0 through 15.
ZBACKUP
is the backup processor in a processor pair. Valid values are in the range from
0 through 15. This field is not applicable in single-processor environments.
Entering values for ZPRIMARY and ZBACKUP is optional in a multiprocessor
environment; the system assigns CPUs if you do not designate any.
