Rudy,

Re: My customers run on Citrix on a daily basis.
Do you manage that or is the Citrix part managed by the customers IT?

  Re: No such errors, ever.

Do you run the Citrix server and the 4D server on the same LAN?  I have 
proposed two solutions to the IT company but they have declined to follow 
through on either.
1 - They build a server in their own data centre to host the 4D database so 
they can have the server on the same LAN as the Citrix servers.  We would 
rather have a happy customer than the small amount of revenue we generate from 
the rented server.
2 - We create a VPN between our networks to try and improve network stability.  
We have a CISCO ASA5515 that all traffic goes through.

Re: Regarding the error message, it may be of help to let the Citrix people 
know that 4D is using multiple ports: by default 19812 and 19813, and then 
19815 or so for SQL server.  You can see on 4D server which ports are actually 
being used, and you can set them to other values.

They have all port information.  We do use different port assignments from the 
IANA defined ports as from time to time they run more than one database on the 
same server, but that works for many other far more saturated servers.  Our 
server is dedicated too running 4D but we have no clue what they run on their 
Citrix servers.

I was thinking of setting up an alternative Citrix solution so we could gain 
some experience with it, do some testing and advise but I have always believed 
Citrix is quite an expensive setup.

Re: Just curious: how fast (or slow) is the direct client connection in 
comparison to the Citrix 4D client connection?

Where clients have a leased line the difference is negligible with great 
stability.  Where clients use ADSL the connection is mostly acceptable although 
occasional dropouts can occur.

Any other experiences from yourself or anyone else would be welcome.

Hi Dougie,

My customers run on Citrix on a daily basis.

No such errors, ever.

Regarding the error message, it may be of help to let the Citrix people know 
that 4D is using multiple ports: by default 19812 and 19813, and then 19815 or 
so for SQL server.
You can see on 4D server which ports are actually being used, and you can set 
them to other values.

Hope this helps.

Just curious: how fast (or slow) is the direct client connection in comparison 
to the Citrix 4D client connection?

Citrix Playbook

[Douglas Cryer via 4D_Tech]

Hi folks,

Most of our clients connect to their databases over the internet directly with 
4D in client server mode.  We have one client where they have an company 
running their IT and do everything via a Citrix connection.  They have been 
having on-going issues with the connection dropping and causing fairly random 
4D errors on the client.   The latest is "Only one usage of each socket address 
(protocol/network address/port) is usually permitted."

Some of their people have used the system in direct connection mode for days 
and do not experience these disconnects.  So we suspect it is an issue with the 
Citrix setup or the network connection from the Citrix server and the 4D Server.

We do not know Citrix in any detail nor do we have access to their Citrix 
Server.  The IT company has no experience of 4D and are blaming it for the 
issues.

Does anyone have a Citrix playbook that we could read and pass on to them in 
order to establish a more sensible dialog.
