Questions about SAP Mobile platform 2.3

Dear Experts,

Could you guys clarify the points below?

1) Which is the minimum requirement for installing a scale-out node on Sap Mobile Platform 2.3?

One data-tier and two server-tiers (primary and secondary), right?

2) Which tasks can we do in a package (MBO or Hybrid App) during its deployment? Does it keep locked completly during deployment?

3) Which kind of packages can we deploy through SCC? Only Hybrid App packages and Agentry applications, right?

4) An user reported a problem informing that the shortcut to access an application is not being showed on HWC. How to troubleshoot?

5) What is the differences among the following types of packages: replication, messaging, unified, DOE-C, ODATA?

6) Which kind of applications iare within a MBO Package?

7) Hybrid App does not have MBO?

I have not found the answers for the questions above through SAP Learning Hub and Infocenter.sybase.com.

Best regards

    These are all answered in the online documentation and there are several tutorials showing you how to do this. Primarily, the SMP 2.3.4 documentation is the latest complete set where 2.3.5 and later are just subsets of what may have been changed.

    1) Which is the minimum requirement for installing a scale-out node on Sap Mobile Platform 2.3? One data-tier and two server-tiers (primary and secondary), right?

    In general yes, but I have seen customer's implement the data-tier on an MS-Cluster and then have a SMP server on each cluster.  I would suggest not to use this approach as it really limits HA functionality.  So yes, one data tier host and two SMP server host is the minimum.  Remember, primary and secondary are logical roles and not physical roles so the servers can switch roles depending on several factors.

    2) Which tasks can we do in a package (MBO or Hybrid App) during its deployment? Does it keep locked completly during deployment?

    I'm not clear on what is being asked here.  Deploying an application is a sunchronous process and the app is locked until it's fully deployed.

    3) Which kind of packages can we deploy through SCC? Only Hybrid App packages and Agentry applications, right?

    MBO packages can be deplyed via SCC also.

    4) An user reported a problem informing that the shortcut to access an application is not being showed on HWC. How to troubleshoot?

    If it's a server initiated HWA, that may be expected.  If it's a client initiated HWA, make sure the HWA is assigned to the user in SCC.

    5) What is the differences among the following types of packages: replication, messaging, unified, DOE-C, ODATA?

    All MBO packages are now techincally Unified, Unified support Replication Based and Messaging Based synchronization.  Replication vs Messaging is basically which API you are using to synchronize your application. OData in 2.3.x specifies the client application is using SMP as a proxy and SMP handles the security and backend communication.  DOE-C application means application it is written to communicate with DOE and SMP artifacts are generated based on a ESDMA file created in DOE.

    6) Which kind of applications are within a MBO Package?

    At a very high level, MBOs are created from a backend Enterprise Information Systems (EIS) such as databases or web services.  The actual deployed objects are a mixture of Java Classes and SQL objects that reside within the SMP distributed java container.

    7) Hybrid App does not have MBO?

    A Hybrid Application (HWA) may not be using an MBO, but most do.  Usually, MBOs are created and HWA are generated from them.

    Please see the complete documentation at http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.pubs.docset-SMP-2.3.4/doc/html/title.html as all this is discussed in a much greater detail.

    Regards,

    Kevin
