Just curious -- were these z/OS messages complaining about buffers being full, or were they messages from the HMC? My guess is the HMC was complaining, not z/OS, because z/OS console support uses a large data space to buffer messages going to an EMCS console. What z/OS release are you on? >"The command is not available for extended consoles". EMCS consoles are a bit of a misnomer because an EMCS console is really nothing more than a programming interface; there is no physical console associated with one (unless some other programming that plugs into the interface provides one). The EMCS interfaces were initially created for the TSO Operator facility and now many automation products plug into them as well. Within z/OS console support, we have also found them to be handy for various internal uses, one of which is queuing the messages destined for the HMC System Console. The queues for EMCS consoles are distinct from those that support MCS and SMCS consoles (which all use a shared queue structure). All of the CONTROL (K) commands apply to those shared queues, and not to the separate EMCS queues. The EMCS queues are presented through programming interfaces that allow the queues to be manipulated, and many of the programs that plug into those interfaces do provide ways of manipulating the queues. Unfortunately, the program that back-ends the HMC System Console within z/OS console support and that plugs into the EMCS interfaces is not one of those programs. >It seems strange that in this case there is nothing that can be done! The HMC System Console has always been a bit of an orphan, and for a variety of reasons we have not lavished a lot of attention on it. There are things that could be done, but folks need to complain through things like SHARE requirements if they want to see anything happen. >Perhaps it was a stupid question ... I'm a rookie ... but that's how you learn things If you're questions and my answer stir up some discussion and some SHARE requirements, we will both come out ahead. I'm always happy to answer questions. W.
