Blackberry device goes offline in Sybase Control Center

0 Kudos

Hi,

When i register a Blackberry device via Sybase Control Center, it remains online for few mins and then it goes offline even when the device is active.

Is there any configuration to increase the timeout value for Blackberry in Sybase Control Center.

Thanks for your support in Advance.

What I understand so far, this is works as designed.

The status "online" refers to the messaging communication channel. The messaging communication stack does automatically establish this channel and generally does maintain it so new items can be delivered to the app.

This general rule does have device specific exceptions:

  • iOS - the app needs focus, other wise the OS shuts it down so no communication possible. Notification are then handled via APNS
  • BB - the OS will "freeze" or stop the app when it is idle (no focus) for some time to preserve energy and CPU performance. Notifications are done via BES MDS notification channel.

On WM + Android, you will see them both staying online as long as there is an IP connection.

Maybe it would ge good, if other people with BB+SUP real world experience could talk about their BB behavior to qualify my statement.

Hi Dirk,

I have bad experience with BB + SUP. In fact, I have reported the issue to SAP and waiting for the reply.

I am using Mobile Sales 2.0 ( SAP delivered application) on BB device. Even when I log in to the application, the device won't turn 'online' in SCC. Because of this, the data flow ( both ways) won't happen even when the user is accessing the application.

Every time, I have to go to Sybase settings and then restart the client. I cannot dare to perform this for the real users.

Do you have any hints on this ?

Regards,

Viju

  • What BB device?
  • What SUP sever version?
  • What is your network setup? Particularly between SUP & BES? is there a firewall?
  • Did you check the SUP logs if the communication to the BES is ok?
  • A network connection is there? (qualified? sure not a network issue between BB and BES?)
  • Get the device side messaging logs with log level 5, have a look.
  • What exactly does not work for you? More details in the error description plz

Hi Dirk,

My answers:

1> BlackBerry Bold 9900 ( OS 7.0)

2> SUP 2.1.3

3>  Network set up looks like this BB device <-> BES <-> SUP ( I don't think a firewall exists because device directly connects to BES)

4> I haven't mentioned BES information in SUP. As of now, we are not enabling BES Push notification.

5> This is qualified. The BES team says that the connection between BES and BB is proper

6> Yes, I have shared this with SAP. I didn't quite well understood with the messages. I can share it with you if you can share your mail id.

7> When the user logs in to the application, the application is not getting connected to SUP server. In order to obtain data, user has to manually to go Sybase settings and click on 'restart client'. Then the application establishes connection with SUP, After this, the data flow happens.
