<div class="WordSection1">
<p class="MsoNormal">Good morning OPLINTECH,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Fair warning, this may not apply to all of you, and may also require modification of parameters for it to work on your system.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="text-indent:.5in">We use III’s telrenew for our telephone renewal system. Like most things III, we struggle with their software working reliably and can’t get them to support it. For years, (and I really do mean years) we have been
checking the telephone renewal hotline every morning as part of our morning routine in IT. Sometimes if it would die over the weekend, or right after close, it would be down till next business day when we checked it. We also had times that it would die out
an hour after we checked it. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="text-indent:.5in">Before you start to ask why we don’t just monitor it and reopen it when it closes, well it’s not that simple. We run Nagios as monitoring software for all servers and critical applications. Nagios tells us when
things are not responding and offline. The issue with telrenew though was not that it was crashing, but that it was locking up. You would log onto the server, and there it would be in all of its frozen glory. However windows did not see it as un-responsive.
Patrons of course seem to know the second something is no longer working and would decide that this was something that the director of the library needed to know about, instead of just calling and letting us know it was down.
<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="text-indent:.5in">This gets me to the meat and potatoes part of this email. After hearing that the director was getting patron calls about this, I sat down and tried to come up with a way to “fix” the issue. I tore down the application
code and tried to sift through anything useful. There were no command line parameters you could send, and nothing I could see helpful in the code. (Admittedly I am NOT a programmer.) If you use telrenew you know that when it first opens, you then have to
select the “renew” option to start the program, the other button is for settings. So we were stuck. Even more so because the app was not actually crashing or being non-responsive according to windows.
<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="text-indent:.5in">My next step was to spend some time watching the process on the computer and coming up with a way that I could get the program to lock up on demand so I could test my script. (BTW to lock it up, just open a second
instance, worked every time.) After lots of tweaking, below (and attached) is what I came up with to band aid the program. This has been in place now for almost 5 months and we have not had any more issues. Sorry for the long winded email, but I hope that
this script can help other people. Enjoy!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><u>Explanation of Script:<o:p></o:p></u></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="text-indent:.5in"><i>Preface</i>: Because this script implements keystrokes, you must have the computer\server logged on at all times for this to work. We set ours up with autologon, removed any session timeout options, and set up
VNC so we could access the machines current session. This PC now stays logged in 24/7.

</span></span><![endif]>After the script checks to make sure it’s memory usage is not bloated, it then checks to see if it’s even running. This is a two-step process involving checking if the program is just open, or if its open and running. If it is open and
running then nothing happens. If it is just open but not running, it kills the process, reopens, and sends the “enter” keystroke to start the “renew” portion of the program. (Just open it uses under 4000k of memory, open and running it uses around 5000K) It
also opens the program and sends “enter” if it’s just not running at all.<o:p></o:p></p>
