This chapter describes how to configure communication between GINA applications. The
configuration does not require any modifications to the source program. However, it cannot
take place while the application is running; rather it must be performed

 the applica-

tion

.

The configuration of T-ORB is based on the configuration of BEA T

UXEDO

. Knowledge of the

respective manuals will therefore aid comprehension. These manuals are listed under

 at the back of this manual.

The

 WinConfig

graphical user interface is only available on UNIX platforms and only for

openUTM.

❍ ❍ ●

To operate a distributed system on the basis of GINA, certain information must be known
on the desired system structure, the current parameter settings of the host, and the char-
acteristics of the GINA applications.

The configuration tool described here records this information in the form of a general sys-
tem description, from which it generates the data required by GINA.

The information you must enter can be divided into the following parts (see Figure 35 on
page 156):

–

specifications on system-wide settings, such as the participating systems

–

specifications on host-specific parameters, such as operating system resources

–

specifications on application-specific parameters, such as the number of work pro-
cesses

Practically speaking, some of the parameters can be specified in more than one of these
areas. In such cases, the values set higher up in the hierarchy must be taken as default set-
tings. These values are then overwritten by the settings in more specific areas. The desired
settings can thus be specified separately for each application if required (customizing).

If parameters are specified more than once at system level, they are then valid for the rest
of the system level or until a new parameter is specified.
