SYS1.PARMLIB(ASCHPMxx)

The ASCHPMxx parmlib member contains scheduling information for the ASCH transaction scheduler, and is described in the MVS Initialization and Tuning Reference (SA22-7592). The following directives are known to impact z/OS® Explorer:

MAX(nnnnn)

An optional parameter of the CLASSADD definition that specifies the maximum number of APPC transaction initiators that are allowed for a particular class of transaction initiators. After this limit is reached, no new address spaces are created and incoming requests are queued to wait until existing initiator address spaces become available. The value should not exceed the maximum number of address spaces allowed by your installation, and you should be aware of competing products on the system that will also require address spaces.

Value Range:  nnnnn is a decimal value from 1 to 64000.
Default: 1

Note: If you use APPC to start the TSO Commands service, then the transaction class used must have enough transaction initiators to allow one initiator for each concurrent user of z/OS Explorer.
