Diagnosis
Technical constraints:

• There does not necessarily have to be any work processes of the Update
2 type (low-priority update). However, as high-priority updates couldbe delayed without them, we recommend that you configure at least onework process of the Update 2 type for each system.

• You can set the number of these work processes using the system
parameter rdisp/wp_no_vb2.
