Types of definitions

When defining EE connections, you can choose between predefined (static) or dynamic definitions.

Static definitions are more secure, which is often a priority for host connections. The disadvantage is that more labor is required to maintain definitions.

Dynamic definitions are less secure but require fewer definitions to maintain.

Table 1. Comparison between static and dynamic definitions
Predefined (static) definitions	Dynamic definitions
Elaborate implementation; many individual definitions; DYNPU=NO	Streamlined implementation; no individual definitions; DYNPU=YES
More secure	Less secure
Ability to manage specific connections with user-defined names	Minimal control over assigned names
More flexible - different characteristics for different connections	Less flexible - most connections have same set of characteristics
Transmission group number (TGN) helps identify partner; specific TGNs can differentiate media type to enhance problem determination	Control of TG number only by defining TGN on the DYNTYPE=EE PU entry in a model major node
More resources (definitions) to maintain	Self-managing

It is possible to have EE connections between the following endpoints:

Two static end points
One static end point and one dynamic end point using DYNPU=yes
Two dynamic end points defined with connection network
