Synchronize-All-Jobs Controls whether the the LPD print symbiont process running in an inbound execution queue (TCPIP$LPD_IN_ nodename_nn) will synchronize on the completion of each job that it submits to a final destination print queue. If the LPD service log option LOGOUT is set using the TCP/IP management command SET SERVICE/LOG, when a print job submitted by the symbiont process completes, the LPD server synchronizes and sends an OPCOM message containing the job number, queue name, and user and host names of the submitter. Each synchronization causes the consumption of one slot of the symbiont process’s AST quota and some dynamic memory. If many jobs submitted by an LPD symbiont process are pending (for example, because the print queue to which they were submitted has been stopped), the symbiont process can exhaust its AST quota or virtual memory. If the Synchronize-All-Jobs option is set to FALSE, synchronization occurs only for print jobs that have either an LPD mailback completion notice or a temporary layup file sent from the LPD client to be used in the printing of the job. Setting this option to FALSE helps limit the exhaustion of dynamic memory or AST quota when many print jobs are outstanding, because most print jobs do not use mailback completion (/PARAMETERS=MAIL) or layup files (/PARAMETERS=LAYUP_DEFINITION). The default setting for the Synchronize-All-Jobs option is TRUE, which is appropriate for most sites. Systems with heavy inbound processing across many print queues might need to set this option to FALSE.
