Well we do have this feature in the C++ version via the reset method on=
Session. This will clear out the sequence numbers and reset the
connection. This isn't exposed in java. The java version is getting v=
ery
popular and I'm sure we will be rapidly exposing more and more of the C=
++
api as people discover these things.
BTW I checked in the patch for the repeating groups. You can check out=
any
of the following build labels from the repository to get a patched vers=
ion
1.3.2:
BUILD_windows_vc6-22
BUILD_windows_vc7-20
BUILD_linux_pgcc_2_95_2-20
BUILD_solaris_gcc_2_95_3_stlport-18

My request for an interface to start and stop the session comes mostly
during our testing phases where we need to recycle the session once in =
a
while. I apologize if the request comes out of ignorance (we are still=
relatively new to FIX messaging), but we need to basically delete the s=
tore
files whenever we want to simiulate a new session (i.e. start over). F=
or
now, this isn't a big deal for us, but I have seen it in the API of oth=
er
FIX engines, so I thought others might find it useful.
Clearly though, the issue with groups and repeating groups via Java aff=
ects
us much more. We will probably need to spend more time with those type=
s of
issues than with issues like controlling the session.
Thanks,

The only way to do this currently is by setting the session times in yo=
ur
configuration file. By doing that you can have sessions start and stop=
during various times of day. I guess to do what you want some sort of
boolean is needed to allow you to override the session times. Is this =
what
you are thinking of?

Is there any planned way to do shut down a session on a per-session lev=
el
rather than the entire engine?

The proper way to stop the initiator is simply to let the onRun method
exit. This will cause the initiator to close itself down.

Folks,
I am experimenting with QuickFix using Java interfcace, and I have a co=
uple
of questions. I have created a CLIENT (initiator) and a SERVER (accepto=
r)
which run on different JVM. A structure of both programs is idential
excluding that the CLIENT uses Initiator class and the SERVER uses Acce=
ptor
class. Initially both of them create initiator or acceptor objects and
start
them. The object that implements Application interface is a simple logg=
er
with an inifinite loop in onRun(). Acceptor.start() method is blocked u=
ntil
onRun() is running. That's why the SERVER listens infinitely.
I intend to send messages being outside from onRun() method of clients.=
To
make this possible I start a simple thread that starts initiator.
Something
like this:
(new Thread() {
public void run() {
initiator.statr();
}
}).start();
where initiator is an instance of Initiator class.
After that the CLIENT goes to sleep for awhile (10 secodns). The SERVER=
and
the CLIENT successfully establish a session and wait. When the CLIENT w=
akes
up it just tries to stop the "started" initiator. The call to
Initiator.stop() method doesn't return and the session doesn't finish.
Instead onRun() is called again. And when the time of Heartbeat message=
comes up LOGON procedure is initiated.
See the log (FIX 4.1):

Is it allowed to use QuickFix this way? Where am I wrong? I don't know
where
to dig. Thanks.
