Hello monks

the situation: I am working for a company using a mainframe system (3270 sessions), and for some massive correction activities, we have a server (Windows) with several IBM personnal communication terminal emulator. These terminals are driven by Perl scripts using the OLE interface (solution equivalent to the one described in Interact with mainframe screen).

The problem is that we want to launch several scripts in parallel, each one using 2 or mores terminals.
We have a limited number of terminals, and to avoid having to select in each scripts which terminals to use, I am thinking about a way to dispatch on demand the terminals to scripts.

My idea is to write a perl script, running as daemon, which task would be to dispatch available session ID on demand, and be informed by scripts when sessions are not used anymore (thus returned to the pool of available sessions).

my questions are:

• what do you think generally about the solution ? do you have other idea on how to do it ?
• How the scripts should communicate with the daemon ? I'm thinking about using local sockets.
• How the daemon should keep the available and unavailable terminals ID ? in memory is easier, but in case of restart of the deamon, the info would be lost...

Thank you in advance for your help, and don't hesitate to help me improve my post/questions, as this is the first time I'm posting on perlmonks.
