8 Operating GINA applications

This chapter provides an introduction to the runtime administration of conﬁgured GINA

applications.

8.1 Communication administration

8.1.1 Communication structure of a server application

Communication in GINA is based on the

open

UTM transaction monitor. Its functionality with

respect to transaction-monitored message interchange and restart is thus inherited in the

event of error. With the support of the XA interface, data storage is also integrated in this

transaction bracket. Knowledge of the administration and diagnostic options offered by

UTM is required for the successful operation of (networked) GINA applications.

A precise description of the concepts involved can be found in the Developer Manual [13].

The description of the network in the conﬁguration generator determines which partners

can communicate with each other and in what way (chapter 6 on page 43).

8.1.2 Communication structure of a client application

Unlike the transaction-monitored communication between server applications, client appli-

cations (generally as GUI applications) connect to server applications using non-transac-

tion-monitored protocols. Here too, knowledge is required of the underlying

open

UTM-Cli-

ent product and the diagnostic tools. A precise description can be found in the correspond-

ing manuals on

open

UTM and

open

UTM-Client or in the communication protocols used by

open

UTM [29], [31].
