SQ_MAXQBUF keyword - QPF_OPTIONS command

SQ_MAXQBUF is an optional keyword for the QPF_OPTIONS command that applies only to a Shared Queues environment. When the IMS QBUFMAX startup parameter is set to 0, SQ_MAXQBUF is used to override the local queues QBUF value used to calculate the high RRNs for the Short and Large messages. The high RRNs are key to determining when to invoke the QPF Monitor, Protect and Overflow Phases. If this parameter is not specified, and QBUFMAX is set to 0, QPF will calculate the high RRN values using either the current numbers of local Queue buffers allocated, or 9999, the higher of the two values. SQ_MAXQBUF can be set to any value between 10000 and 9999999.
