You can enable DB2 to support Microsoft Transaction Server by setting the TP_MON_NAME database manager configuration parameter to "MTS". You do this on the machine where the DB2 CAE client runs with MTS.
Use the following CLP command to enable support:
db2 update dbm cfg using tp_mon_name MTS
A sample application will be provided to verify the installation. When this sample becomes available, it will be identified on the IBM website. Set your URL to "http://www.software.ibm.com/data/db2/library" and search for a DB2 Universal Database "Technote" with the keyword "MTS".
