GSSB and ULS
The UTM GSSB and ULS memory areas are available throughout the cluster in UTM cluster applications. This means that all node applications have read and write access to these areas. The user data is stored in cluster page pool files (see "UTM cluster files") and the management data for the GSSB and ULS areas is stored in the cluster GSSB file and cluster ULS file, respectively, see "UTM cluster files".
You can use the KDCDEF statement CLUSTER ... DEADLOCK-PREVENTION to specify whether or not openUTM is to perform additional checks to prevent deadlocks if memory areas are locked.
GSSB and ULS data are also saved in the case of UTM-F.
TLS
The UTM TLS memory areas are created locally to the nodes in UTM cluster applications, as each TLS is assigned to an LTERM or (OSI-)LPAP and a connection can be established to every LTERM or (OSI-)LPAP in every cluster node at any time. A separate version of the memory area therefore exists in each cluster node.
