Abstract

A method is described which: 1. Reconnects SNA local and remote transactions based on a special conversation correlator for fast performance; 2. Offers security protection for invalid access to a SNA transaction; and 3. Offer an algorithm to create a unique conversation correlator. A local SNA Transaction Program (TP) can communicate with a remote transaction program via the SNA LU6.2 protocol. When a local TP communicates with the remote TP, a conversation is created. For the local TP, there is a Resource Control Block (RCB) associated with it. Likewise, on the remote end, there will be a RCB associate with the remote TP. The SNA LU6.2 allows the local TP to be disconnected from the remote TP temporarily and to be reconnected some time later.
