The generation of a UTM cluster application differs in the following ways from that of a standalone UTM application:
There are the additional statements CLUSTER and CLUSTER-NODE as well as the operand value GEN=CLUSTER in the OPTION statement, see "KDCDEF statements".
When a UTM cluster application is generated, UTM cluster files are also generated, see below.
Only one copy of the KDCFILE is permitted, i.e. KDCFILE=(...,SINGLE) must be specified in the MAX statement (default value).
The size of a UTM page must be 4K or 8K (MAX statement, BLKSIZE operand)
Please also note the following important differences that apply during a UTM cluster application run:
In a UTM cluster applications, the user data that applies globally throughout the cluster is stored in GSSB and ULS areas. In the case of UTM-F, the service data is also stored in these areas.
The KDCFILEs of the node applications contain only the user data that is local to the node.
