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.
| 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
