To function in a Sybase XA environment, your Adaptive Server must be licensed and configured to use the distributed transaction management feature. See the Adaptive Server Installation Guide and Using Adaptive Server Distributed Transaction Management Features for more information.
If your Adaptive Server is licensed to use distributed transaction management, you can enable the feature using the enable dtm configuration parameter:
sp_configure 'enable dtm', 1
You must restart Adaptive Server for this parameter to take effect.
