5.3.4 Update the ZPARM

You need to update the ZPARM of each MQ subsystem participating in the

sharing group to define the sharing group and provide information about the DB2

sharing group that is holding the MQ tables. In the CSQ6SYSP section of the

ZPARM table, the parameter QSGDATA (queue-sharing group data) needs to be

updated with the following information:

QSGDATA=(Qsgname,Dsgname,Db2name,Db2serv,Db2blob)

Qsgname The name of the queue-sharing group to which the queue

manager belongs

Dsgname The name of the DB2 data-sharing group to which the

queue manager is to connect

Db2name The name of the DB2 subsystem or group attachment to

which the queue manager is to connect

Db2serv The number of server tasks used for accessing DB2

Db2blob The number of server tasks used for processing DB2

blobs

In our case, this was QSGDATA=(MQQG,DB8QU,D8QG,10,4).
