MC SERVICES P6
MC_SERVICES_P6 is a system parameter that specifies MEMORY CHANNEL message size, the body of an entry in a free queue, or a work queue. The maximum value is 65536, and the minimum value is 544.
The default value is 992. This value is suitable in all cases except for systems with highly constrained memory. For such systems, you can reduce the memory consumptions of MEMORY CHANNEL by slightly reducing the default value of 992. The value of MC_SERVICES_P6 must always be equal to or greater than the result of the following calculations:
- Select the larger of SCS_MAXMSG and SCS_MAXDG.
- Round that value up to the next quadword.
The value of MC_SERVICES_P6 must be the same on all nodes connected by MEMORY CHANNEL.
