Structure connection disposition

The structure connection disposition attribute indicates how the connection is handled in the event of abnormal disconnects from the structure.

DELETE: Indicates that if a VTAM® node fails or is forced to disconnect because of some type of failure, the node's connection definition is removed.
KEEP: Indicates that if a VTAM node fails or is forced to disconnect because of some type of failure, the node's connection remains defined but is in a failed-persistent state. Failed-persistent state indicates that if a VTAM node fails or is forced to disconnect because of some type of failure, the node's connection remains defined but is in a failed-persistent state. The failed-persistent state also indicates that recoverable data is located in the coupling facility structure.

Note: A network operator might see VTAM in a failed-persistent state because of a VTAM failure or because VTAM disconnects from the coupling facility. To ensure that data needed to recover is available, the operator should not issue the MVS™ SETXCF FORCE command.
