In TWS for z/OS. WAIT workstation is a general non reporting workstation with the WAIT option set to Y.
The Wait workstation allows to define a dummy operation that runs for a specified period of time. This
time period is defined as the duration of the operation.
The TWS for z/OS Workstation Analyzer (WA) subtask has in charge many functions, one of this is to complete the
WAIT workstation operations when the wait time is reached, another one is to select and start the operations.
This last WA process continues while there are operations that can be started.
When there is an high workload, that means an high number of jobs to submit, the WA can miss the Wait workstation
intervals time and the operations on these workstations can overrun.
The MAXSUBJOBS parameter allows the WA to stop the submission and to verify the processes related to time
dependent events (e.g. wait work station delay, long duration alert).
MAXSUBJOBS defines the maximum number of jobs that the TWS for z/OS can submit consecutively without
stopping the submission process to check for other activities.
The MAXSUBJOBS value can be specified in the OPCOPTS statement.
Its value can be also set via operator command "/F subsystemname,MAXSUB=xxxx" where xxxx is the maximum
number of jobs that can be submitted consecutively. Its value can range between 0 and 9999. Using 0 (the default),
TWS for z/OS does not interrupt job submission to process time-dependent events.
This enhancement has been added starting from TWS for z/OS 8.5.1 with APAR PM97681.
