Sybase Unwired Platform End-to-End Process Flow

Understanding Sybase Unwired Platform processing flow at a high level between the enterprise information system (EIS), Sybase Unwired 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 Sybase Unwired Platform communications between the EIS, Sybase Unwired Platform components, and device clients. The diagram also shows relay server and relay server outbound enabler (RSOE), which are optional components.

Sybase Unwired Platform communications
SUP Debugging Communications

Unwired 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 Sybase Control Center.
Data services (DS) – responsible for back-end interaction, data integrity, and transactions.
Cache database (CDB) – is a runtime cache database used by Unwired Server. By default, an embedded SQL Anywhere® database server is used as the CDB, as shown in the diagram. However, you can configure Unwired Server 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 data source is available, and check logs for possible communications problems between the EIS and Unwired Server.
Unwired Server – data services (DS)	Using Sybase Control Center, enable data services subsystem logging. Review interactions for getting data and sending transactions.
Unwired Server – core and administrative subsystem (MMS)	Using Sybase 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.
Unwired Server – messaging subsystem	Using Sybase Control Center, enable messaging subsystem logging. Enable messaging server-side logging for one or more of its modules. Retrieve client-side messaging-based synchronization trace by sending a request to the messaging device from Sybase 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 (RSOE) – if installed	Enable relay server tracing. Review relay server log. Check Microsoft Windows system log files. Check relay server configuration.
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 Sybase 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 Unwired Server, and the certificate.
