Nancy:
Little things like this are really slowing down my progress, but I am
learning a lot about Linux and GTM in the process. Getting a little déjà vu
of the early days in VistA. The only FileMan doc was, I think, 20 pages
long (but, as George T will attest), everything was there, you only needed
to know where to look. We would call him up, he would say (without
looking), "page 18, on the bottom, there in the example".
Here is my origional hosts file, right after installation of Redhat 9:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
GTM>D GETENV^%ZOSV
hostname: Unknown host
GTM>ZWRITE
Y="VAH^ROU^^ROU:"
GTM>
Here is the “hosts” file as it is now.
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 ROU x1-6-00-e0-18-62-af-ec
GTM>D GETENV^%ZOSV
GTM>ZWRITE
Y="VAH^ROU^ROU^ROU:ROU"
If I take out the third field, leaving only two,
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 ROU
GTM>D GETENV^%ZOSV
hostname: Unknown host
GTM>ZWRITE
Y="VAH^ROU^^ROU:"
Now change only the “hosts” middle field to AAA, to avoid confusion
GTM>D GETENV^%ZOSV
GTM>ZWRITE
Y="VAH^ROU^AAA^ROU:AAA"
GTM>
Here is the code in ^%ZOSV, you can see what the problem is, the -s argument
tells GTM to retrieve the shortname from the hosts file, and it doesn't work
if there is no longname. What name it gets, I think MUST correspond to
Volume Set, in order for things to work right. I think also, Volume Set
should be three letters.
GETENV ;Get environment Return Y='UCI^VOL^NODE^BOX LOOKUP'
N %HOST,%V S %V=^%ZOSF("PROD"),%HOST=$$RETURN("hostname -s")
S Y=$TR(%V,",","^")_"^"_%HOST_"^"_$P(%V,",",2)_":"_%HOST
Q
RETURN(%COMMAND) ; ** Private Entry Point: execute a shell command & return
the resulting value **
;
; %COMMAND is the string value of the Linux command
N %VALUE S %VALUE="" ; value to return
N %FILE S %FILE=$$TEMP_"RET"_$J_".txt" ; temporary results file
ZSYSTEM %COMMAND_" > "_%FILE ; execute command & save result
O %FILE:(REWIND) U %FILE R:'$ZEOF %VALUE C %FILE:(DELETE) ; fetch
value & delete file
;
QUIT %VALUE ; return value
;

Subject: Re: [Hardhats-members] Volume Sets
Please show me the output of GETENV.... and hostname -s and what Linux
distribution are you using? ROU is usually the volume set. I am using
Fedora Core 2. I am glad it worked but I am beginning to think it was dumb
luck!
