Description
DFHWSSOF is the CAVM state management SIGNOFF request handler. During SIGNON processing, this module is established as an ESTAE exit for the CAVM task. It purges outstanding I/O requests, reads the state management record from the control data set, and searches it to see if this job has signed on to the CAVM. If so, it updates the status CI and state management record to indicate that the job has signed off. It makes the TAKEOVER message available to DFHWSRTR when an active system signs off after takeover has started.
