- This has given us massive headaches. Our system administrator has
- increased one of our RS/6000s to what he says is the limit of 64.
- Sorry, but I don't know how.
-
- When we first reported this to IBM, IBM said "Xterm is provided on the
- RISC/6000 as a binary sample only and is unsupported." (More on this in
- a minute.) After explaining to the #!%&*s that the problem wasn't with
- xterm, but with their system chewing up ptys, they reexamined the problem
- and determined that the software that controls our many X Stations was
- not properly releasing the ptys when the X Stations were being turned
- off. As yet, this has not been fixed.
-
- A resonable solution might be to run xdm. Unfortunately, our ex-MVS
- system administration can't bring themselves to run this unsupported
- program either. If only IBM shipped systems running xdm out of the box...
- At least we can start xterms ourselves. Anyway, when our system admin-
- istration remembers, our system gets rebootted every couple of days.
- When they don't, we live with confused users without ptys.
-
- Now more as promised above... When is IBM going to learn that support
- for standards means more than just lip service? If they had to log into
- six different architectures on a daily basis as I sometimes do, then maybe
- they would understand the value of xterm. We did not buy IBM hardware to
- run IBM's custom X clients. We bought it to run core clients like xterm
- so that the IBM systems would integrate gracefully with our other hardware
- so our users would be less confused so that they would be more productive.
- We want our users to run xterm so that, in the future, they will require
- less retraining. Vendor independence and portability of user knowledge
- are the two big payoffs of open systems. Until recently, it has been in
- IBM's interest to resist open systems. IBM may not (want to) understand
- the motivation behind open systems, but we must. IBM may want to dictate
- the way that we use their hardware, but that's just not going to happen.
- We must work together to demand the support we need, not the support IBM
- thinks we need. They make excellent hardware but they've got to start
- cooperating.
-
- Support X core clients or lose customers!
