RE: RE: OB-Users Digest, Vol 38, Issue 2

Hi again,

I succesffuly (thanks to you) installed the last version (4.3.1).

Both client and server, actually it's on the same computer so far.

> Is the NameService also based on JOB-4.3.1?

Absolutely

> Are the 500 messages/second all calls to this oneway function?

Not only I have differecnt function very similar (below you'll find the i=
dl):

#pragma prefix "monitorplug.com"

module MonitorDynamic
{
    interface DynamicData
    {
        oneway void ask_update(in string id, in double price, in double s=
ize, in long long time, in double ref);
        oneway void bid_update(in string id, in double price, in double s=
ize, in long long time, in double ref);
        oneway void last_update(in string id, in double price, in double =
size, in long long time);
        oneway void ask_vol_update(in string id, in double ref, in double=
 price, in long long time, in double imp_vol, in double delta, in double =
gamma, in double vega, in double theta, in double rho);
        oneway void bid_vol_update(in string id, in double ref, in double=
 price, in long long time, in double imp_vol, in double delta, in double =
gamma, in double vega, in double theta, in double rho);
        oneway void mid_vol_update(in string id, in double ref, in double=
 price, in long long time, in double imp_vol, in double delta, in double =
gamma, in double vega, in double theta, in double rho);   =20
        oneway void last_vol_update(in string id, in double ref, in doubl=
e price, in long long time, in double imp_vol, in double delta, in double=
 gamma, in double vega, in double theta, in double rho);
        oneway void general_update(in string id, in double net_change, in=
 double percent_net_change, in long cumul_size, in long bl_trade_volume, =
in double vwap);
        oneway void general_OHLC(in string id, in double open, in double =
high, in double low, in double close);
        oneway void general_derivative_update(in string id, in double set=
tlement, in double open_interest);
    };
};

It's not crashing, it's just locked/hanging/very slowing


I'll try to send you a mini version of my program to reproduce the proble=
m.

Thanks again for your concern.

Please make sure that the OB-Users mailing list is copied on all

Since you were able to test this scenario with JOB-4.3.1, I can assume=20
that the issues you were having trying to build this version of Orbacus
were resolved, correct?=20

As for the problem that you are seeing, would it be possible for you to
build a small test program that could reproduce this problem and send it
along? Obviously we are dealing with an issue that canot be reproduced
at will, but a test program that mimics the interactions of your client
and server (the oneway call for example) would go a long way toward a
resolution.

The above configuration (upgraded to JOB-4.3.1) is for your client=20
machine, correct?

Is the NameService also based on JOB-4.3.1?

Are the 500 messages/second all calls to this oneway function?

So, just to be clear, your application is hanging as opposed to
