Users who were signed on at the node application at the time it terminated abnormally or who possess an open service bound to this node application can sign on at another node application. In this case, any open service for such a user is lost. An open service can only be continued when the user sign-on is performed after a warm start of the abnormally terminated node application.
However, such users cannot sign on at another node application until the abnormal termination of the node application has been detected:
The abnormal termination of the node application has already been detected:
Users with RESTART=NO can sign on at another running node application. Users with RESTART=YES can sign on at another running node application if the application has been generated with CLUSTER ABORT-BOUND-SERVICES=YES and the user does not have a node-bound service with a transaction in the state PTC.
The abnormal termination of the node application has not yet been detected:
The attempt to sign on is rejected until the monitoring node has detected the failure. As soon as the failure has been detected, processing continues as in the first case above.
