ATM Transaction Manager

The transaction management service now runs as a service within the Adabas System Coordinator daemon. Runtime parameters for the transaction manager are now defined in the parameter input of the System Coordinator daemon within which the transaction manager is operating. Please refer to the Installation section for detailed installation instructions.

Installing CICS Resource Manager Interface for z/OS and z/VSE

With version 8.2, there is no longer a requirement to link an Adabas Transaction Manager component with the Adabas TRUE. The standard Adabas System Coordinator implementation now provides all necessary CICS Resource Manager Interface services. Please refer to the Installation Procedures section for detailed installation instructions.

Recovery File

Recovery information is now maintained in a single direct access file defined to the Adabas System Coordinator daemon within which the transaction manager runs as a service. This recovery file is shared by all transaction managers operating within the same Adabas System Coordinator group. Please refer to the Installation section for detailed installation instructions.
