Communication error, problem synchronizing with Android using SUP2.2

[Former Member]

Hello, I'm having problem synchronizing my application.

I followed the steps explained in this post http://scn.sap.com/community/mobile/blog/2012/05/02/sup-212-native-android-mbo-non-doe-based-approac... to configure the application to go through relay server. I had a previous installation that worked great buy now I'm having some difficulties.

I manage to register the application correctly, I can see it in SCC but when it tries to synchronize I get a communication error.

The exception is as follows:

com.sybase.persistence.SynchronizeException: com.ianywhere.ultralitejni12.implementation.JniException: UltraLiteJ Error[-1305]: MobiLink communication error -- code: 63, parameter: , system code: 110Details:

StreamErrorCode = 63

StreamErrorMessage = null

I read it may have something to do with a socket that cannot be opened but I don't know how to search for the communication error. Any ideas?

When I try the deploy on a different sup server with the relay server in the same computer, the application works. I'm not sure what it may be.

Thanks in advance,

Lucia Cianelli

I tried everything you suggested but it's still not working. The application subscribes correctly but it does not synchronize. I attach the images from our sup configuration for the relay server and the file rs.config to see if you can find anything that might be wrong. Any help would be great! we have no idea what else to try!

Thanks in advance,

I attach more images from SCC and some log files from rsoe to see if you can help.

Thanks,

Finally, Are you synchronizing using the "supAdmin" user if no please try with the "supAdmin" user?

If you try to use a user without admin role you will not be able to sync ( Ex: If you have created a user under application connections ). In the production environment you need to use LDAP user.

Hi Midhun,

Thanks for your help but I'm using "supAdmin" so it's something else.

Any other ideas?

Former Member  The log tells that "The backend farm is disabled according to the relay server configuration". That means the farm ID you are providing is wrong or it is not configured correctly.

Please check it.

Lucia,

Do you see any errors at your RSOE, is it's status is showing as running? you are using sybase hosted relayserver or you have a relayserver of your own.. by any chance your subscription of the relayserver is expired !!! you have to renew it then!!!

We checked that, it was because of a change we had made to test the behaviour but now it doesn't show that error anymore.

Any other ideas?

Thanks,

Lucía

[Former Member]

Hi Srinivas,

I don't see any errors in my RSOE logs, I attach them here. The only thing that could be something wrong is an HTTP message with code 204 but I'm not sure.

I have my own installation of the relay server.

Any other ideas? Any help would be great!

Hi Lucia,

Had a quick glance through your code, I'm not seeing where you are setting the protocol being used to do the synchronisation.

So you say it is connecting - this is good as it means you are getting past the first stage and your problems lie in the sync settings. For synchronising you need to provide your host, port and also your protocol (as well as some network stream parameters in certain scenarios).

If the app is trying to connect over HTTPS (using SSL) and your relay server only accepts HTTP then you might see an error 63 or vise versa for that matter.

If you are connecting over HTTPS then if the server's CA is not embedded in the app and set in the stream parameters of your synchronisation connection you would also see errors like this.

This URL is a really good reference for understanding error codes BTW.

Hope that helps,

Brenton.

Hi Lucia.

I used to got this error too. I solved by input stream parameter like this:

trusted_certificates=;compression=zlib;url_suffix=ias_relay_server/client/rs_client.dll

hope it work with yours .

[midhun_vp]

Have you debugged the program? In which line of code the issue comes?

Can you try calling the subscribe() method where you are doing the registration.

- Midhun VP

[Former Member]

Hi Midhun,

I debugged it and the issue comes in the line where we are making the first synchronization.

I attach the files. The exception happens in line 278 of the file main.

Where do I do the subscribe() ? How would the line to add be?

Lucía

[midhun_vp]

Can you please try after adding below code after the line "cprof.save();"

Log.d("Subscribe", "Start");

                                                  PlanFiaV2DB.subscribe();

                                                  Log.d("Subscribe", "End");

                                                  PlanFiaV2DB.submitPendingOperations();

- Midhun VP

[Former Member]

Hi Lucia,

Ensure to call subscribe() before calling synchronize()

Hi Lucia,

Do you face this problem only in device or in emmulator alone.

Hi Srinivas,

The issue happens in the device.
