When adopting Adabas Transaction Manager it is recommended to run Adabas with DTP=RM. This setting enables the RM role of Adabas so that it can be coordinated by Adabas Transaction Manager to provide full DTP support. These databases are referred to as Adabas RMs.

DTP=NO can be used to disable the RM role of Adabas. This is not recommended. When this setting is used the database cannot participate in DTP coordination so all transactions for this database are processed using serial ET, with no guarantee of DTP integrity.
