In a Sysplex environment, only one Datacom MUF is required. CA-11 on all other systems access the MUF via an XCF connection.
In a Sysplex environment, only one Datacom MUF is required. CA-11 on all other systems access the MUF via an XCF connection. Each system in the Sysplex must have access to module DBSIDPR. Each system must also have the Datacom SVC loaded by CAIRIM.
There are 3 parameters in Datacom that should be taken into consideration for the XCF connection. These parameters are MUF, XCFFROM and TASKS.
MUF Parameter
MUF AD10MUF,99,NO This statements gives the MUF a name.
XCFFROM Parameter
XCFFROM *,SYSPROD Defines remote system that may access mu
TASKS Parameter
TASKS 35,33K,0,0,29 # of TASKS, SIZE,0,0,XCFTASKS
EXAMPLE: A SYSPLEX ENVIRONMENT WITH 3 LPARS AND MUF RESIDING LPAR3.
LPAR 1: 2 TSO USERS AND 1 CICS USER
LPAR 2: 2 TSO USERS
XCFTASKS= LPAR1 + LPAR2
XCFTASKS= (6 + 3) + (6 + 2) = 17
Note: With PTF QO81922 for the Automatic Resume/Heartbeat functions, add 1 to DBTASK value to get the total number per system for the XCF task number. Also for the best performance, MUF must reside at the LPAR which has the most workload of batch processing.
