Astor : Remote Host Connection Failed

General Development
1

Hi All,

I am exploring Starter Device Server. I am able to start device server locally through astor, but when i am trying to start device server remotely it is not working. I created new host in astor and trying to communicate with newly created host but all time it shows Starter is not running on that host even though Starter is already running on that host.I am starting the Starter on that host remotely still it shows Starter is not running when i am trying to communicate from my host. In jive i am able to change tango host. I attached screen shots for the same.

Does any of you have any idea what might be the problem?
Thanks in advance.

Hi

The only one who seems to have a good naming is the last one,
if the starter device (tango/admin/01hw255506) is defined in database running on 01hw255551 host.
See documentation:
Starter doc
and
Astor doc

It seems to work in miscellaneous branch, but I can’t see anything.

Hi Pascal,

I just trying to give some different names. I have also tried with last one (01hw255506) but still facing same problem.
You can see attached screen shot with it.

Hi Anshul,

Is tango/admin/01hw255506 declared in 01hw255551:10000 Tango Database or is it declared in 01hw255506:10000 Tango database?
Your comments from the first post make me think you are actually starting your Starter/01hw255506 instance with a TANGO_HOST environment variable set to 01hw255506:10000.
If this is the case, an astor started with TANGO_HOST=01hw255551:10000 environment variable won’t be able to contact your starter device since it is not exported in 01hw255551:10000 Tango database.

Could you please tell us what is the TANGO_HOST environment variable used when starting the Starter device server on 01hw255506 host?

Cheers,
Reynald

Hi Reynald,

Q: Is tango/admin/01hw255506 declared in 01hw255551:10000 Tango Database or is it declared in 01hw255506:10000 Tango database?
Ans: Yes, “tango/admin/01hw255506” is declared in “01hw255551:10000”. But it is not show as exported in “01hw255551:10000” , even when it is running on “01hw255506:10000”

Q: Could you please tell us what is the TANGO_HOST environment variable used when starting the Starter device server on 01hw255506 host?
Ans: While starting “Starter device server on 01hw255506 host” the TANGO_HOST was “01hw255506:10000”.

Just wanted to ask:
Does remotely starting of a device server using Starter DS works only for same TANGO Facility? (In other words, can we start a device server in TANGO Facility 2 using Starter Device Server in TANGO Facility 1.)

Hi

If, as you wrote, “While starting “Starter device server on 01hw255506 host” the TANGO_HOST was “01hw255506:10000”.”
It is normal that a Astor started with TANGO_HOST=01hw255551:10000 cannot see it.

Astor is used to manage all starter servers running on same TANGO_HOST.

Hi Pascal,

Thanks for the confirmation.

Dear Team,

Do we have a work around to do this.
I mean, I want to start a Device Server which belongs to another Tango Facility, is it possible remotely?

Hi
The only work around I know, is to start an Astor on each TANGO_HOST.
May be in the future, we can imagine to develop a multiple tango host manager.
