I want to find if an OpenVMS system is a Server or a Work Station.
Is there any DCL command or lexical function for this ?
Please help.
Thanks,
Vineet

Re: How to identify if system is a server or workstation
a workstation can as well be a disk- and boot-server.
A workstation usually must run some window system to be recognized as such:
if f$getsyi("WINDOW_SYSTEM") .ne. 0 then -
"this is a workstation".
Server systems will have system parameters
MSCP_SERVE_ALL or TMSCP_SERVE_ALL /= 0

Re: How to identify if system is a server or workstation
Even the WINDOW_SYSTEM parameter probably is not enough: a server may have WINDOW_SYSTEM=1 to enable X11 client programs to display somewhere else.
So one has (in case of window_system == 1) to see if an X11 server is running:
once has to do a process-scan to see if a process with name beginning with "DECW$SERVER"
exists.

Re: How to identify if system is a server or workstation
My 4100 and GS160 with 7.3 are workstations according to your rule.
In fact none of my stations and servers display are servers (all return 1).

Re: How to identify if system is a server or workstation
As I have told: the distinction is not well defined.
If something is a potential workstation (because it has a graphic head), but has not enabled the software to use it, then I don't call (or count) it as a workstation.

Yes, if they have a graphic head and run DECW$SERVER.
They most probably are servers as well.

Re: How to identify if system is a server or workstation
couple of think involve on that.
Like what hardware you are using, and your license loaded in the system.
Well there is no such separate operating system called VMS workstation or
Server. It depends upon you, how you are using the VMS system as workstation or server.

Re: How to identify if system is a server or workstation
$ ! Unless we are specifically skipping workstation specific setup,
$ ! or we know for a fact (as reported by SYS$STARTUP:LICENSE_CHECK.EXE
$ ! in an earlier stage of the startup process) that this system is not
$ ! correctly licensed, determine if this is a workstation
$ !
$ IF F$TRNLNM("DECW$IGNORE_WORKSTATION") .OR. (F$TRNLNM("DECW$LICENSE_CHECK") .EQS. "FALSE")
$ THEN
$ decw$device == "NONE"
$ ELSE
i.e. those 4100/GSnnn having a graphic console, but are considered as servers, which almost never use the graphics console, should define the logical DECW$IGNORE_WORKSTATION before DECW$STARTUP to inhibit start of DECW$SERVER.
Then by my definition they are not workstations (in the software meaning).
