Problem with TangoTest device server

# 5 years ago
peipei	Pascal Hi Seeing your picture I confirm that your server TangoTest/test is NOT registered (not running) on your machine named ZPY-PC. Why ? I don't know. A problem at server startup ? Normally, when a server start it register itself in database as running on the host. The Starter/Astor tool will get server list using this feature. But in your case, we cannot see TangoTest/Test on host ZPY-PC. maybe i think is there any problem at my tangotest server starup? because i startup it from astor, no pop-up windows to tell me the Server is OK…. when i startup it again,it will tell me the server is running.but the answer of DbGetHostServerList is the same as before. i have try to registered it from Jive but nothing changed Edited 5 years ago Attachments:

philippeg	peipei i have copy the tangotest.exe to C:\DeviceServers\bin TANGO_HOST=ZPY-PC:10000 other config as pictures show am i right? Seems OK to me for the Astor config step but I'm not TANGO under windows expert. However, I see in your first snapshots a 8XNUX… host running a DB but I see here you set TANGO_HOST to ZPY-PC:10000. Perhaps I missed something but do you you have two computers (8XNUX… and ZPY-PC, one server and one client, and then is TANGO_HOST defined to the same value on both?) or just one? - Philippe

YES I have two computers. TANGO_HOST=ZPY-PC:10000, the ZPY-PC is the host computer and running MYSQL 8XNUX… is the client and TANGO_HOST=ZPY-PC:10000 too,so astor at 8XNUX… can link to database directly.

Pascal	Did you start Astor and Starter with TANGO_HOST=ZPY-PC:10000 ? Because on your screen shot we saw another TANGO_HOST. Attachments:

TANGO_HOST is the way for each client to understand where to connect to the TANGO central database. - Philippe

You will need to start again your device servers. :'( problem dont fix~~ the TANGO_HOST was the same for 2 weeks…. when i finish the install of tango system into client computer , i change the TANGO_HOST of client computer from localhost:10000 to ZPY-PC:10000. These steps were doing at 2 weeks ago..

Reynald	Hi Peipei, Did you try to do the following?: Kill your TangoTest instance (using Windows Task Manager or sending the kill command to dserver/TangoTest/test device) on ZPY-PC Verify that your device server is marked as not exported/not running in jive Try to start the TangoTest/test device server from astor on the same host Please do not hesitate to ask questions if some steps I described above are not clear. If this doesn't work, I would try to ensure TangoTest/test is not running on your computer and try to start it up from a console/terminal, using -v4 or -v5 option to see if there are some eventual error messages during the startup. `TangoTest test -v4` I hope we will manage to understand the strange behaviour you're observing. Do you see the same problem if you create another instance of TangoTest (for example: TangoTest/test2)? Rosenberg's Law: Software is easy to make, except when you want it to do something new. Corollary: The only software that's worth making is software that does something new.

Hi Peipei,

Did you try to do the following?:

Kill your TangoTest instance (using Windows Task Manager or sending the kill command to dserver/TangoTest/test device) on ZPY-PC
Verify that your device server is marked as not exported/not running in jive
Try to start the TangoTest/test device server from astor on the same host

Please do not hesitate to ask questions if some steps I described above are not clear.

If this doesn't work, I would try to ensure TangoTest/test is not running on your computer and try to start it up from a console/terminal, using -v4 or -v5 option to see if there are some eventual error messages during the startup.

TangoTest test -v4

I hope we will manage to understand the strange behaviour you're observing.
