Hi, guys, this is Yamashita, an electric engineer of plant equipments.
This is exactly my case, but I want to know abou, so if anyone know about UNIX system, please answer my question.
My colleague and supplier began to investigate some new factory CIM system, because, so far, we use a kind of original system (this kind of
system should be called "DCS", right?) of the same supplier, but after about 2003, this system cannot get anymore for stopping production.
You may guess it's too soon to investigate, but this system is quite huge, and we should bring this new system into another new factory in
about 2 years, we cannot say this is enough.
Anyway, the system engineer of the supplier said to my colleague who is in charge that the new system would be some UNIX system based, of
cource we agreed in this point, but the Solaris was quite heavy for this purpOse so he would use Linux based system.
Unfortunately, my colleague doesn't have enough knowledge about UNIX itself, because he never touch that and only use Windows9*, so in this
situation, the vendor can control him easily.
It might cause some trouble in some cases.
So, I want to ask some question.
I've heard that non-commercial UNIX system, like Linux and FreeBSD(I prefer this), is weaker than commercial UNIX, like Solaris, in the region of memory protection ,process administration and etc., but, for me, I'm not *pure* UNIX system engineer just hobbist, so I don't know exactly about that.
But I guess, this kind of differences must be very important, critical matter if in the case of quite important server system.
Can anyone explain about these for me ?
And next, the SE said that Solaris is *heavy* than Linux.Of course, I know that Solaris is heavy, but, nowadays, I've heard that Linux
system became heavier and heavier, so we don't have to care about this weak point, right ?
regards.
