[dhi-servers] NameServer communication problems

[Charles Ammon]

Hi,

I contacted the author of ADORB (Victor Ananiev) and he seems to have
figured out what is going on. The issue is the character code set
translation (good call Philip).

If Victor is right, it appears that the server restart was not exactly
what was running before Wednesday. Please see the response from him
below. He makes several suggestions for me to work around the issue,
but if possible, the easiest for the group of people running my
clients would be to make the adjustment at the server to be the same
as it was before restart on Wednesday.

Would this be possible? If not, I can start on the workarounds.

Chuck

Hi Charles,

The problem is in the character codeset negotiation. For some reason
they don't allow UTF8 (CORBA code 0x0501001).
It connects if I send ASCII (0x00010020) or no codesets at all.
Apparently they have changed something in the configuration or,
according to their log, forgot to register a converter for UTF8.

For the time being you can change the value for native char code in
the file IDLTaggedComponent.m
//static int _nativeCharCode = 0x05010001;
static int _nativeCharCode = 0x00010020;

I don't know how this can affect the rest of your application though.

I will look for a better solution meanwhile.
The other way is to remove codesets from the service context using
interceptors that I have added in the version 1.5.

Regards,
Victor Ananiev

Hi,

I am sorry to bother you. I am an ADORB user and you helped me figure
some things out about using CORBA a long time ago. Since then, I have
been developing and using ADORB to talk with a seismic data server -
and all has been running well until this week. Now I can't connect to
the nameserver I have been talking to for more than a year. They did
restart the machine running the server, but they don't think that
anything has changed - it must have. I have codes that I have not
recompiled that used to work, but don't any more...

I downloaded the most recent version of IDLBrowser and have been
trying to connect to the server, but all I get is a time out. I appear
to be the only one who is having problems (all others use java-based
orbs to communicate).

The server address is 128.95.166.129:6371. Using IDLBrowser, I have
tried talking to the server with GIOP 1.0, 1.1, and 1.2 (1.2 used to
work). All time out.

I have been in touch with the server administrators and this is the
error that they see when I try to connect:

If you have any ideas, can you please let me know?

Thank you,
Chuck Ammon
