DFS3675I INVALID LOGON TO THE APPLID ACB - NODE nodename
Explanation
In an extended recovery facility (XRF) environment, IMS was using MNPS for session persistence. As a result, there were two VTAM® application control blocks (ACB) in use - the MNPS ACB and the APPLID ACB. The APPLID ACB can only be used by the MTO and the XRF surveillance link. However, a VTAM terminal nodename, which is not the MTO or surveillance link, attempted to logon to the APPLID ACB.
System action
IMS rejects the logon attempt.
Operator response
Log the terminal onto the MNPS ACB. Use /OPNDST command to automatically use this ACB, or use /DISPLAY ACTIVE DC or /DISPLAY HSB to determine the MNPS ACB name.
System programmer response
No action is required.
