The enable dtm parameter enables or disables basic DTM features. When enable dtm is set to 1 (on), Adaptive Server supports external transactions from MSDTC, and from X/Open XA transaction managers via the DTM XA Interface. See the XA Interface Integration Guide for CICS, Encina, and TUXEDO for more information.
To enable basic DTM Features, use the command:
sp_configure 'enable dtm', 1
You must restart Adaptive Server for this change to take effect.
