OS: win10 pro 21H2 64bit
tango-9.2.2-64x
MYSQL 5.7
JAVA 1.8.0.281
nssm 2.24
TANGO_HOST=localhost:20211
MYSQL_USER=tango
MYSQL_PASSWORD=tango2020
my computer name :ZPY
JAVA_HOME TANGO_ROOT all set well

Tango-Databaseds running well ,JIVE and astor can connect to tangoDB,
AS FIG.1 show
the question is:

when i use astor–command—add a new host
i imput like these:
HOST NAME: ZPY
Device Servers PATH: C:\DeviceServers\bin
push create and tell me
A starter server has been created in TANGO databased
you can now start it on ZPY machine
————————————————–
BUT when i start it at command line :
C:\Program Files\tango\bin>start-starter.bat zpy
Starter::Starter() init device tango/admin/ZPY
UseEvents = False
interStartupLevelWait = 1
serverStartupTimeout = 1
fireFromDbase = 1
logFileHome = c:\temp
StartServersAtStartup = 1
AutoRestartDuration = 0
Tango exception
Severity = ERROR
Error reason = BAD_PARAM
Desc : This server must run on zpy and not on activate
Origin : Starter::check_host()

Received a CORBA_Exception
Exiting
as fig.2 show
——————————–

when i uses nssm.exe install Tango-Starter, with argument:ZPY
environment variables input TANGO_HOST=localhost:20211
The Tango-starter is always paused, as fig.3 show

please tell me how to fix this problem, many thanks!

Reynald	Hi, The Starter is checking at startup that its instance name really matches the real name of the host where it is running. See https://gitlab.com/tango-controls/starter/-/blob/main/Starter.cpp#L207 and https://gitlab.com/tango-controls/starter/-/blob/main/Starter.cpp#L1429-1459 This means that `Starter.exe ZPY` must run on a host named ZPY, recognized with this name on the current network. From what you're writing, you computer name is indeed ZPY but I don't know why, the Starter found another name for it: "activate". Could it be that your PC network name is actually "activate" instead of ZPY? If not, maybe you're facing a bug of cppTango on Windows because the Starter is getting the hostname by using Tango::Util::instance()->get_host_name() method. The hostname used by Tango is then the one computed by Tango::Util::init_host_name() method : https://gitlab.com/tango-controls/cppTango/-/blob/9.3.5/cppapi/server/utils.cpp#L1349-1519 There might be a bug in cppTango 9.2.2 which might not be compatible with recent Windows versions and some network setups? As a work-around, it looks like you can define the DEBUG environment variable to avoid this host check. This is normally used only by the Starter/Astor developers for debugging purposes and I'm not sure of the consequences of using this hack. Please note that there is currently a work done by Observatory Sciences Ltd for the Tango Community to create a new Tango distribution installer on Windows. You can get a beta version from the link given by Aya on the following gitlab comment: https://gitlab.com/tango-controls/TangoTickets/-/issues/61#note_1047813549 Please give it a try if you can and report any issue you encounter with this beta version on https://gitlab.com/tango-controls/TangoTickets/-/issues/61.

Hi,

The Starter is checking at startup that its instance name really matches the real name of the host where it is running.
See https://gitlab.com/tango-controls/starter/-/blob/main/Starter.cpp#L207 and https://gitlab.com/tango-controls/starter/-/blob/main/Starter.cpp#L1429-1459

This means that

Starter.exe ZPY

must run on a host named ZPY, recognized with this name on the current network.

From what you're writing, you computer name is indeed ZPY but I don't know why, the Starter found another name for it: "activate". Could it be that your PC network name is actually "activate" instead of ZPY?

If not, maybe you're facing a bug of cppTango on Windows because the Starter is getting the hostname by using Tango::Util::instance()->get_host_name() method.

The hostname used by Tango is then the one computed by Tango::Util::init_host_name() method :
https://gitlab.com/tango-controls/cppTango/-/blob/9.3.5/cppapi/server/utils.cpp#L1349-1519

There might be a bug in cppTango 9.2.2 which might not be compatible with recent Windows versions and some network setups?
