At a previous company where I used Solaris I put the client temp files in the /tmp directory (effectively RAM) and that gave a positive performance boost.
I'm now on an AIX system (OE 10.2B on AIX 7.1) and there is a "lot" of spare memory (over 20GB). I have tested creating a RAM disk and putting client temp files in there - and Progress is quite happy with that. We have a mixture of character on gui clients. Character clients put there temp files in /work1/tmp, and the appservers put their temp files in /work1/tmpas.
My basic plan is to create two RAM disks and mount one over each of the directories as mount points.
There are users right around the world and so there is no time at all when no users would be accessing the system - hence there are always open temp files in the two directories.
So ... to my question. If I mount a RAM disk over the existing directories - what will happen to the clients that already have temp files in existence? Will they crash? Does anyone know? I've done considerable searching - but I can't find any references to this particular situation.
Please note: Modifying the parameter files to change to a different directory is possible - but not easy (many instances).
