JOBPACING statement

Use the JOBPACING statement to limit the number of jobs that the LPD server concurrently writes to the JES spool or send to another LPD server. This limits memory requirements in LPD, but does not cause any jobs to be lost. Received jobs are queued until they can be processed.

Syntax


              .-----------.   
              V           |   
>>-JOBPACING------limit---+------------------------------------><

Parameters

limit: An integer specifying the maximum number of jobs that the LPD server concurrently writes to the JES spool or send to another LPD server.

Usage notes

Concurrent processing of jobs requires memory for control blocks and large I/O buffers. Some concurrent job processing keeps a long job or slow receiving LPD from delaying all the other jobs. Too much concurrent processing causes thrashing and requires extensive memory.
JOBPACING defaults to the preferred value 5 when the keyword is not specified. Increasing this value might cause memory allocation problems with certain system configurations.
If LPD runs out of memory, reduce the value of either JOBPACING or STEPLIMIT.
