Linux client - cannot connect to JServer

Question

Server with database - Oracle 8.1.7 on Windows 2000
Client - Linux RedHat 7.2
When I trying to connect to JServer using sess_sh:
sess_sh -u arseniy -p mypasswd -s sess_iiop://199.58.1.113:2481:orcl
I get this error message:
javax.naming.CommunicationException: Unknown service: :session1 [Root exception is javax.naming.CommunicationException: Unknown service: 199.58.1.113:2481:orcl]
When I try to use DBAStudio, I get something like this:
VDJSERVER-1516: Failed to get a new JServer session.Unknown service::OEM0
The most incomprehensible thing is that if I reboot my client to Windows 2000, it works, in other words - the file LISTENER.ORA on the server seems to be correct.
So why I cannot work with JServer under Linux!?
Thank you in advance...

Answer 1

I uninstalled the
http://support.microsoft.com/kb/2574819
and it resumed working for me as well as I had exactly the same issue here.
there is a point though: removing this KB removes the UDP connection capability of RDP 8.0; arguably the most significant breakthrough the RDP 8 has to offer. shouldn't it be addresses and the problem handled in a better way?
if RDS Team claim that they've brought all the "adaptive network", "adaptive graphics" , "WAN enhancement" and etc to Windows 7 with the RDP 8 update(see links below), then shouldn't it be as available and as glitch-free as
it is with a windows 8 VM?
basically it is unacceptable to force the client to turn off the "automatic determine" feature ; either manually or through the RD-ConnectionBroker tweak of the following link (Jeroen Link):
http://support.microsoft.com/kb/2863663
because if it is a supported feature, it has to be supported without IFs and BUTs. this is definitely a bug that needs to be addresses.
RDP 8 for windows 7 links:

another thing I noticed : with RDP 8 features enabled, you don't get the event ID 2 as this link suggests anymore:
http://technet.microsoft.com/en-us/library/ff817587
maybe you'll get event 34 as this one says. but I am not quite sure:

P.S. I am using 2012R2 Hyper-V and it does have this problem as well, so I don't think that compatibility roll up update will help.
