Debugging Windows and Windows Mobile Device Development

Device client and Unwired Server troubleshooting tools for diagnosing Microsoft Windows and Windows Mobile development problems.

Client-Side Debugging

Problems on the device client side that may cause client application problems:

Unwired Server connection failed.
Data does not appear on the client device.
Physical device problems, such as low battery or low memory.

To find out more information on the device client side:

If you have implemented debugging in your generated or custom code (which Sybase recommends), turn on debugging and review the debugging information. See Developer Guide for Windows and Windows Mobile about using the MBOLogger class to add log levels to messages reported to the console.
Check the log record on the device. Use the DatabaseClass.GetLogRecord(Sybase.Persistence.Query) or Entity.GetLogRecords methods.

This is the log format
```
level,code,eisCode,message,component,entityKey,operation,requestId,timestamp
```
This log format generates output similar to:
```
level code eisCode message component entityKey operation requestId timestamp
 5,500,'','java.lang.SecurityException:Authorization failed: Domain = default Package = end2end.rdb:1.0 mboName = simpleCustomer action = delete','simpleCustomer','100001','delete','100014','2010-05-11 14:45:59.710'
            
```
- level – the log level currently set. Values include: 1 = TRACE, 2 = DEBUG, 3 = INFO, 4 = WARN, 5 = ERROR, 6 = FATAL, 7 = OFF.
- code – Unwired Server administration codes.
  - Replication-based synchronization codes:
    200 – success.
    
    500 – failure.
- eisCode – maps to HTTP error codes. If no mapping exists, defaults to error code 500 (an unexpected server failure).
- message – the message content.
- component – MBO name.
- entityKey – MBO surrogate key, used to identify and track MBO instances and data.
- operation – operation name.
- requestId – operation replay request ID or messaging-based synchronization message request ID.
- timestamp – message logged time, or operation execution time.

Server-Side Debugging

Problems on the Unwired Server side that may cause device client problems:

The domain or package does not exist. If you create a new domain, whose default status is disabled, it is unavailable until enabled.
Authentication failed for the synchronizing user.
The operation role check failed for the synchronizing user.
Back-end authentication failed.
An operation failed on the remote, replication database back end, for example, a table or foreign key does not exist.
An operation failed on the Web Service, REST, or SAP® back end.

To find out more information on the Unwired Server side:

Check the Unwired Server log files.
You can also obtain DEBUG information for a specific device:
- View information through the SCC administration console:
  1. Set the DEBUG level to a higher value for a specified device through SCC administration console:
    1. On SCC, select Application Connections, then select Properties... > Device Advanced.
    2. Set the Debug Trace Level value.
  2. Set the TRACE file size to be more than 50KB.
  3. View the trace file through SCC.
- Check the <server_install_folder>\UnwiredPlatform\Servers \MessagingServer\Bin\ClientTrace directory to see the mobile device client log files for information about a specific device.
Note: It is important to return to INFO mode as soon as possible, since DEBUG mode can affect system performance.
