On some of our workstations, every time we run ANY DECwindows application
(Clock, Calculator ...), the number of available global pages decreases by
278. Usually people try to keep number of available global pages to a minimum
so this may cause problems when running a lot of DECwindows applications
on VMS. It should be noted that this doesn't seem to happen on all of our
workstations - only some.
Has any one seen this ? Seems like a user quota problem ?

I assume the local transport uses a shared global section (278 pages?) to pass information between Xlib and the Xserver. | |||||

Re: .-1 That is it. Thanks. Jatin | |||||

Is this expected behaviour ? 278 pages seems like a large number for shared memory. Is this documented in the release notes or somewhere ? Jatin | |||||
| 586.4 | STAR::ORGOVAN | Vince Orgovan | Fri Apr 14 1989 00:03 | 3 | |
That's the expected behavior - about 280 pages for each shared
memory connection. I don't believe that it's documented.

Please do consider documenting it in the release notes and under SET DISPLAY command. Currently, if you do not have enough global pages, this is what you get: $ MCR DECW$CLOCK X Toolkit Error: Can't Open display %DWT-F-DWTABORT, xtoolkit fatal error Not very informative. The problem is compounded with products like DECdecision where with a single DCL command a user can fire four (or more) DECdecision component applications. Jatin | |||||
