Forcing the server will never set the ECBUNWT bit in a work unit of the client. ECBUNWT is set in the ECB (or ECBLIST) being waited upon by a work unit that is abterm'd (in part so that that work unit might wait again, since you cannot wait on an ECB that is already waiting). Force is not an abterm. Forcing the server will not by itself terminate any client thread. If the thread wakes up for some reason in a cross-memory environment that requires the server space, then upon that wake-up, the thread will be abended due to inability to reestablish the cross-memory environment. >Will a post be honoured when ECBUNW is set? yes >POSTing an ECB with ECBUNWT already on will not wake up your waiting client. POSTING an ECB with ECBUNWT is by definition posting an ECB that is not waiting. The wait bit is not on. Therefore there is no work unit to wake up.
