You should provide the system programmer in the installation using your multisystem application with overview information about the application, including a description of the purpose of the groups and the members within each group. Additionally, the following information will help the system programmer plan the sysplex:

• How many groups and members will be defined.
• The names of the groups that will be defined.
• Whether members require permanent status recording.
• The size of the messages that will be sent, how frequently the messages will be sent, and the distribution of the messages amongst the members.
• The consequences that might occur if XCF does not have enough message buffer space to send one or more of your messages.
• The effect of altering the application's configuration on the amount of signaling that might subsequently be generated.
• Specific work load characteristics that might aid in planning transport class definitions.
