Daylight Saving Time (DST) causes lease loss and SUP cluster failover.

This issue is caused by the MobiLink synchronization server and only appears with MobiLink version 11.0.1.

Workaround: The two options to work around this issue are:
  • Upgrade to SUP 2.1.x (The issue is not present in MobiLink version 12.0.1, which is included with SUP 2.1.x)
  • Shutdown all nodes just before DST and then restart the nodes just after DST. This method will work when changing both to and from DST.

The Relay Server URL Prefix property is not persisted on the client.

If the URL Prefix is configured to a non-default value on the Sybase Settings screen in the "Sybase Mobile Workflow" application on an Android device, that new value is not persisted or used when connecting to Unwired Server through the Relay Server. Instead, the default is used.

Workaround: None.

The ESDMA converter does not support type definitions within a WSDL

Workaround: Modify the ESDMA to remove any in-line type definitions and explicitly define them. Save and deploy the ESDMA bundle to Unwired Server.

The error 
The input line is too long
displays when upgrading from Unwired Platform version 2.0 to 2.0 ESD#1

If the system environment path is too long for the console window from which you run start-unwired-server.bat, an error occurs.

Workaround: The Sybase Unwired Platform installation directory path is too long. Shorten it, and retry. The default value is C:\Sybase\UnwiredPlatform.

Nodes in an Unwired Server cluster do not start properly after installing the Sybase SAP® Data Orchestration Engine Connector (DOE-C).
If after installing DOE-C, Unwired Server cluster nodes do not start, check the Unwired Server log file for this message: 
java.lang.OutOfMemoryError: GC overhead limit exceeded

Workaround: Add more JVM heap space to the affected Unwired Server hosts. See http://infocenter.sybase.com/help/topic/com.sybase.infocenter.dc01625.0200/doc/html/aba1287411470795.html

Performance issues when a high volume of client activity (synchronizations or logins) occurs on Unwired Server that runs on a 32-bit windows machine.

Unwired Server is only supported on 64-bit machines for production deployments. 32-bit machines do not provide a large number of TCP/IP ports by default. An indication of this problem are synchronization and login error messages in the client log.

Workaround: Use a 64-bit windows server installation for all work other than development testing.

If you are already using an application with one relay server, you cannot switch to another relay server in the same application during runtime.

Workaround: Uninstall, then reinstall, the current application on the device. Before you use the application after the reinstallation, change the relay server information in the Profile screen.

The full range of valid values is not supported if the attribute uses the default datatype (int) for a SQL Anywhere® database column of type unsigned int.

Workaround: To support the full range of valid values for an unsigned int attribute in the EIS, set the datatype for the corresponding MBO attribute as long.
