RE: problem with deployment

Hi Sai,

 

This is a very strange error. We have never experienced a similar
problem. We think it must be a networking setup issue. Could you
complete the following questions?

 

-          Are the two machines connected to the same switch or hub or
are they in different subnets?

 

-          Could you try if "NSLookup" works for both machines?

 

-          What OS do you run in these machines?

 

 

-          The SF daemon uses port 3800 for its RMI registry. Could you
try to telnet into that port to see if is reachable before you try to
deploy anything.

 

-           Just for completeness of info, could you send us the various
settings that the sf display gives you on the help menu (help->info and
help->info prop). You can save or copy the results in a file. Please, do
this for both hosts.

 

I none of it tells us where the problem is we will think up some
diagnostic tests...!

Hi Patrick,

 

I am able to connect to the localhost using sfManagementConsole in both
cases and I am able to deploy the components properly on the localhost.

Just out of interest, did you manage to connect to the localhost in both
cases using ths sfManagementConsiole command?

Hi Julio,

 

I have tried all the steps told by Patrick. I am able to ping the
machines. Its not the problem with the DNS. There is no firewall that
interferes the communiation between the machines.

 
 
These are my results after doing lot of testing 
 
 
 
1) I started sfDaemon on both the machines "knscsl020" and  
  "knscsl018". 
      2) When I try to open the sfmngconsole for knscsl020 from
knscsl018. 
3) When I try to open the sfmngconsole for knscsl018 from knscsl020. 
 
   

Observation:

 

When I follow the steps 1, 2 I get the exception
"java.net.ConnectException" after step 2.

 

When I follow the steps 1, 3 I could able to access the sfmngconsole for
knscsl018 from knscsl020 and I could able to see the deployed
components.

 

When I follow the steps 1, 3, 2 the daemons are communicating properly
and I could able to access sfmngconsole for knscsl020 from knscsl018 and
sfmngconsole for knscsl018 from knscsl020. I am also able to see the
deployed components on both the machines.

 

My observation is: every time I have to do 1, 3, 2 for the daemon
communication to be proper which should not be the case. If I follow 1,
2, 3 the communication is not proper.

 

Once both the daemons are able to communicate then I am able to deploy
the components from one machine to other machine.

 

I am not clear with this way of communication.

 

 

Regards

Sai
