Update generation for UTM cluster applications (Unix, Linux and Windows systems)

Before performing the operations below, please read section "Backing up data"!

KDCUPD allows you to update and convert UTM cluster applications as follows:

• Offline update of a UTM cluster application,
  where the UTM cluster application must be shut down.

• Online update of a UTM cluster application,
  which can be performed while the UTM cluster application is running.

• Converting a UTM cluster application,
  i.e. converting a UTM cluster application from standalone to cluster and vice versa.

When performing a KDCUPD run in UTM cluster applications, you can choose between a node update and a cluster update:

• In the case of a node update, you update the KDCFILE of a individual node application.

• In the case of a cluster update, you update the UTM cluster files created during generation.

You can control these two variants using the KDCFILE and CLUSTER-FILEBASE statements.

The following sections describe the KDCUPD statements that are required for these functions and provide information on how you must first use KDCDEF to create the generation file. In addition, further activities are required depending on the situation, e.g. starting or terminating node applications or the UTM cluster application or adapting the start parameters.

For details see the relevant openUTM manual “Using UTM Applications”, chapter “UTM cluster application”.
