Troubleshooting Options
This section describes the options available for diagnosing process flow problems.
SAP-side Debugging
- Verify the SAP data source is running.
- Verify the SAP data source privileges have been granted properly.
- Ensure the SAP BAPIs are exposed properly as Web services.
- Verify credentials are correct.
- Check for error messages.

SAP JCO Connection Debugging
- Verify the JCo connection is configured properly and is operational.
- Check for error messages.
Sybase Unwired Platform-side Debugging
- Verify Unwired Server is up and running.
- Turn on JCo tracing in the Unwired Server system properties:
- In Sybase Control Center for Sybase Unwired Platform, select Performance Configuration > User Options for your Unwired Server. You can configure JVM parameters in the form -Dxxx=xxx. Add the following JVM parameters:
-Djco.trace_level=[0-10] -Djco.trace_path=[defined_path]
The jco.trace_level determines the level of detail of tracing you get from the JCo libraries. The jco.trace_path determines a directory where trace files get stored. If your SAP-based MBOs fail, turning on tracing can help determine the cause.
- In Sybase Control Center for Sybase Unwired Platform, select Performance Configuration > User Options for your Unwired Server. You can configure JVM parameters in the form -Dxxx=xxx. Add the following JVM parameters:
- Verify the JCo connection is configured properly.
