Glossary
action point
A number of remote subcalls can be started in the T-ORB procedure “action point”.
Given that the →server process is subsequently released, an action point is always a
potential →end of transaction, a potential →monitoring and restart point.
The results of all subcalls are evaluated by the Continuation of the action point. The
continuation is a parallel callback which is only started when all the results have been
received.
A →client cannot recognize whether the →server is carrying out an action point. A
server cannot recognize whether it was called from an action point.

annotation
The parsers of the GINA development systems sometimes need more information than
can be formulated in C++. GINA comments are used for this purpose. They are ignored
by the compiler but not by the GINA parsers. These comments contain a sequence of
expressions that are referred to as annotations.
application
A GINA application is a transaction-monitored application under T-ORB. A GINA appli-
cation can include a number of →server processes. A non-transaction-monitored appli-
cation can be connected to a transaction-monitored application using T-ORB/Client.
asynchronous request/call
When you use the T-ORB procedure “asynchronous call”, the →client does not wait for
the call to be executed and the result returned. Possible results are thus discarded (see
also →notification).
Under T-ORB, even asynchronous requests/calls undergo transaction monitoring, i.e.
they are executed in an independent transaction after a successful end of transaction
(commit). The asynchronous call under T-ORB is a relative →time request with zero
delay.
