Use troubleshooting tips to resolve common
issues. Topics provide information to help isolate and correct
problems.
- Troubleshooting Mobile Business Object Errors
Review these Mobile Business Object issues.
- Troubleshooting a MSSQL Connection
Problem: When using a MSSQL connection, if you use a non-existent database name, such as the default name, pubs, the connection succeeds, but the error log receives continuous errors.
- Troubleshooting ODBC Driver Errors
Problem: If Sybase Unwired Platform is installed and you then install a standalone version of SQL Anywhere 10 and uninstall SQL Anywhere 10, after the standalone version of SQL Anywhere 10 is installed, the registry may be changed, so the ODBC driver cannot be found. An error displays when you try to use the ODBC driver.
- Troubleshooting Previewing of a Database Mobile Business Object
Problem: When previewing a database mobile business object using SQL, the connection is set to chained mode so it can rollback the query after preview. For ASE stored procedures, you may get an error similar to: Execution failed: Stored procedure 'pubs2.dbo.byroyalty' may be run only in unchained transaction mode. The 'SET CHAINED OFF' command will cause the current session to use unchained transaction
- Troubleshooting Preview Errors in Unwired WorkSpace
By default Unwired WorkSpace runs in chained transaction mode when doing a preview of a mobile business object.
- Troubleshooting a SQL Statement Containing a Null
Problem: If you use a database other than Sybase, when there is a comparison operator in a definition SQL statement followed by a parameter, for example: "select * from ... where columnA = '@OP["parameterA"=""]'", and the default value of this parameter is set to Null, you do not get the expected results in runtime.
- Troubleshooting a Multi-Level Insert
Problem: In the device client, the attribute and parameter relationship may not work as expected.
- Troubleshooting Personalization Errors
Problem: After you create create a relatonship between two MBOs, and define peronalization parameters for the second MBO, when you invoke the deployed MBO, no data is returned to the device application for the second MBO.
- Troubleshooting Overriding Personalization Key Settings with SetOverridePersonalization
Problem: If you override a personalization key using the SetOverridePersonalization API, it stays in effect for the lifetime of the current device application session.
- Troubleshooting Menu Items
A user-defined menu item is not displayed on the device client.
- Troubleshooting Synchronization Errors
Use this topic to troubleshoot synchronization errors.
- Troubleshooting Synchronization
Problem: When more than 32 mobile business objects are deployed to a single package and a synchronization is performed from the C# API, an error may occur.
- Troubleshooting a Failed Update of an MBO in the C# Client API
Problem: When you use the C# client API to edit a mobile business object (MBO), then synchronize this update to the server, the update fails at the backend server. Then, if you call the C# client API to delete the MBO, the delete fails.
- Troubleshooting Deployment Errors
Problem: Deploying to a server fails when both attribute mapping and parameter mapping are identical in a mobile business object relationship.
- Troubleshooting Datasource Port Changes During Deployment
Problem: Modified datasource port information is not reflected during deployment of MBOs.
- Troubleshooting Unwired Platform Uninstallation
After uninstalling Sybase Unwired Platform, the OpenDS Windows service is not removed.
- Validation Rules and Error Messages
Understanding and resolving Unwired WorkSpace validation errors helps ensure that mobile business objects (and the device applications that interact with them) perform as expected in an enterprise environment.
- Troubleshooting Device Application Designer Problems
