I've found a few systems where 2 versions of DMQ for Digital UNIX are installed concurrently. My bet is that is not a supported configuration - correct ? I surely can't see any advantages for concurrent versions. Can future DMQ kits installation procedures please abort if any version of DMQ is already installed ? It might only be a minor point, but it's still worth enforcing. Thanks, Craig.

| 2756.1 | yup, it works, and it's not a good idea for my customer | WHOS01::ELKIND | Steve Elkind, Digital SI @WHO | Tue Feb 04 1997 10:26 | 18 |
Actually, my customer makes use of having several releases installed,
since he develops/tests/supports for up to three DmQ releases at a
time, and so do his customers. Aborting the install upon finding a
previous release is probably not a good idea.
It works just dandy, with the following two rules observed:
- You can only have one DmQ version running for a bus at a time,
at least if you're running a dmqbcp process (is this still true
with 4.0? or with 3.x if the dmqgcp is started up directly from
the command line?). We typically see v4.0FT, v3.2A, and v3.0B
running on the same machine at the same time (on different
busses).
- either delete the symbolic links created by the install in
/usr/bin, and /usr/lib, and/or explicitly specify the path in
your startup scripts and make files. We do both.
As to whether it is officially supported? I don't know, but it works
for us.

there are no plans to change the way installations install
over top of existing installations. that is how people
upgrde the software and it is consistent with most other
software products in the industry today. some products
inform users that there is an existing installation. this
is especially true when the product installs in the same
directory for every version. we use a separate directory
for every version so this is not a problem.

Seems unusual - different nodes for diff versions would of course be cleaner - but if it works.. I was mainly checking to see if it was an oversight by your setld kit developer. It appears not. Thx C. | |||||

that and SQA has its requirements when it comes to
install ing different versions of the software.
