Viewing T4 data – on OpenVMS
On a Dutch OpenVMS-SIG meeting last February, there were a number of demos of displaying T4 data other than using TlViz (TimeLine Vizualisation) – which is a Windows application and so requires the files being copied to a location that can be reaced by the program.
But now you can do so on a VMS box using DIX – by Fekko Stubbe, that allows you the same functionality as TlViz does, but on an (XWindows) screen. There are packages for Vax, Alpha and Itanium.
Without the nice features in combining them, there is also a PHP script that I got from one of the ambassadors, it took some tweaking to get it running the way I wanted it, but I’ve got it running from the basic locations: t4$data (for the data) and t4$sys (for the executables). It meant a little adaptation to the PHP-script, and allowing W:E on t4$SYS and the files within, plus setting t4$DATA to be W:RE, all files within W:R, and making that the default protection. By ACL, of course. Acess is limietd to the webserver executor – in my case HTTP$NOBODY, but you may choose to make it generally open…
One more thing that I found: t4$DATA normally contains ALL files that have ever been created. In my case, that includes files dating back to 2006…And since the PHP-code doesn’t scan on date, but on system, it takes a huge amount of time to get the files. And due to the naming convention used, the list is not ordered on date….So it makes sense to cleanup this directory to begin with; next the procedures creating the zip-files (and probably the T4-CSV-files as well) should be adapted to produce a more workable filename – so you’ll get them BY DATE.
