For linking with the cluster software, the types of node switching that you can use depend on whether the light transaction functionality is enabled. The following table lists the node switching types and the usage of the light transaction functionality. Note that the executing node and the standby node are required to be specified in the same operation mode.

Table 16-4 Node switching types and usage of the light transaction functionality

In the execution environment of the batch application, the N-to-1 node switching system cannot be used to enable the light transaction functionality.
