- In article <nat.712532319@sol> you write:
- =Every
- =so often, when I log out of a (DECterm) window, *ALL* my DECterms go poof!!!
- =The Clock, Session manager, and Notepad survive. Any reason why this should
- =happen? What do I need to do to prevent it from happening again? It is not a
- =regular occurance, but often enough to be irritating...
-
- The DECterminal emulator/controller process is crashing. When it goes, so
- goes all of the DECterms.
-
- When you create a DECterm, a controller process acts as the interface between
- the user process and the network. This process usually has the process name
- DECW$TE_<mumble> and is usually running SYS$SYSTEM:DECW$TERMINAL.EXE. Only
- one of these processes is created even if you create a 1000 DECterm windows
- pointing to the same server. The emulator, among other things, also acts
- as a multiplexer.
-
- It looks (sort of) like this...
-
- server side ! ! client side
-
- window 1 <---> X server <---> Network <--> Emulator <---> user process 1
- window 2 <--- ---> process 2
- window 3 <--- ---> process etc
-
- The emulator runs as a detatched process. Later versions of DECwindows
- allow you to direct the Terminal Controller output to a file (to see
- errrors and stack dumps). It's documented in the release notes
- somewhere... try using the logical DECW$DECTERM_OUTPUT, I think
- that is it.
-
- =Also - startup of DECterms is extremely slow. Does anyone have any tuning
- =suggestions to speed things up?
-
- If it's "tough" to create processes on your system, then DECterms will be slow
- since initially two process creations are involved. There are some tuning
- logicals to disable swapping and bump up the Working Set of the controller.
- I think that is in the release notes somewhere.
-
- =Thanks in advance,
-
- Null Perspiration...
-
- =You want more diskquota?! ...Did you bring me some cheesecake? ;-)
-
- So could I trade a RL02 drive for a cheesecake ?
-
- Cheers!
