SAP Mobile Platform End-to-End Process Flow

Understanding SAP Mobile Platform processing flow at a high level between the enterprise information system (EIS), SAP Mobile Platform, and devices is important for troubleshooting, as well as knowing the options available for diagnosing problems at each step of the process.

High-level process flow

This diagram shows a logical view of SAP Mobile Platform communications between the EIS, SAP Mobile Platform components, and device clients. The diagram also shows relay server and relay server outbound enabler (RSOE), which are optional components.

SAP Mobile Platform communications
2.3 debug all process flow

SAP Mobile Server subcomponents include:

Core and administrative subsystem (MMS) – responsible for core services which include device client application interaction management, security enforcement, notifications processing, and runtime component management. MMS administrative services provide the server management interface used by SAP Control Center.
Data services (DS) – responsible for back-end interaction, data integrity, and transactions.
Cache database (CDB) – is a runtime cache database used by server-name. By default, an embedded SQL Anywhere® database server is used as the CDB, as shown in the diagram. However, you can configure server-name to use an existing SQL Anywhere instance as its CDB server.
Messaging subsystem – responsible for transport of messages required for maintaining data integrity on device client applications. It uses a JMS service to upload and download data changes between devices and the cache database.

Troubleshooting options

This section describes the options available for diagnosing process flow problems. Details are provided separately.

Options for diagnosing process flow
Processing component	Diagnostic option
Enterprise Information System (EIS)	Use EIS administrative tools to make sure the datasource is available, and check logs for possible communications problems between the EIS and SAP Mobile Server.
SAP Mobile Server – data services (DS)	Using SAP Control Center, enable data services subsystem logging. Review interactions for getting data and sending transactions.
SAP Mobile Server – core and administrative subsystem (MMS)	Using SAP Control Center, enable core and administrative subsystem logging. Monitor packages. Enable package-level logging. Enable synchronization tracing. View the mobile business object (MBO) operation history.
SAP Mobile Server – messaging subsystem	Using SAP Control Center, enable messaging subsystem logging. Using SAP Control Center, enable messaging server-side logging for one or more of its modules. Note, the messaging sub-system logging controls three modules (SUPBridge, JMSBridge, and WorkflowClient), but other modules may be useful to debug a problem if recommended. Retrieve client-side messaging-based synchronization trace by sending a request to the messaging device from SAP Control Center. Check the module log for SUPBridge and JMSBridge modules messages. The SUPBridge log contains incoming messages from device clients, and the JMSBridge log contains messages going to device clients.
Relay server and Outbound Enablers (RSOE) – if used	Check the relay server configuration. Enable relay server tracing (in rs.config on the relay server machine), and outbound enabler log verbosity using SAP Control Center. Review relay server and outbound enabler log files. Check Microsoft Windows system log files, and web server (IIS or Apache) log files.
Device clients	If the SUPLogger is implemented as part of custom coding, enable Show Log, and set the trace flags. Enable WorkflowClient tracing from the client. Use SAP Control Center to check device information and settings, including the current connection status. Review log files uploaded from the device. Check the configuration, especially connections between the device and SAP Mobile Server, and the certificate. If the device is offline (or cannot connect to SAP Mobile Server), you may not be able to retrieve device logs (for example, messaging logs) from the device through SAP Control Center. If you have physical access to the device, you may connect the device to your computer (either PC or Mac), and use certain third party software to retrieve those log files. For example, you can use iPhoneExplorer to browse through iPhone to extract logs; Windows Explorer to extract logs from Windows Mobile; and Android AVD Manager to get logs from Android.
