copied!<p>Just thinking about this briefly I see three alternatives, all involve use of SDSF (System Display and Search Facility).</p> <ul> <li><a href="https://www.ibm.com/support/knowledgecenter/SSLTBW_2.2.0/com.ibm.zos.v2r2.isfa500/batchy.htm" rel="nofollow noreferrer">SDSF in batch</a> </li> <li><a href="https://www.ibm.com/support/knowledgecenter/SSLTBW_2.2.0/com.ibm.zos.v2r2.isfa500/rexx.htm" rel="nofollow noreferrer">SDSF from Rexx</a></li> <li><a href="https://www.ibm.com/support/knowledgecenter/SSLTBW_2.2.0/com.ibm.zos.v2r2.isfa500/javapl.htm" rel="nofollow noreferrer">SDSF from Java</a></li> </ul> <p>Note that not all mainframe shops license SDSF, which is an IBM product. There exist ISV alternatives; I am aware of these but unfamiliar with them.</p> <p>If this were being done in the shop where I work, I'd establish an SSH session with the mainframe and submit a batch job to execute the Rexx code described at the link. The batch job could check the status of the CICS region and send the email. My preference comes from having done all those things previously, I've just not put them together like this. </p> <p>Your mainframe folks may have a ban on Rexx, or not allow SSH connections to their machine, or be unwilling to set up the Rexx interface to SDSF. They may feel similarly about Java.</p> <p>There may be security implications, the logonID and password will be in your script, yes? What will that ID be authorized to do? How will the script be secured? Is the password for the ID required to expire periodically?</p> <p>All of which is to say that you must work with (probably multiple) mainframe staff in order to make this process function correctly. None of these questions is designed to stop you from accomplishing your goal; your goal must be accomplished without compromising system security and integrity.</p> <p>Some other things to think about...</p> <p>Why are you checking to see if the CICS region is up? If it is because, (e.g.) you will begin a batch process to send messages to the region if it is up and notify someone if it is down, then you are best served building the error handling into your batch process instead.</p> <p>Mainframe shops typically have some automation software in place to notify people when a significant event occurs - bells ring, lights flash, pagers go off, emails are sent, etc. Maybe what you're trying to do is already being handled in a different manner.</p>
