[ome-users] [ome-devel] omero web problem with 4.4.10

[Harri Jäälinoja]

Dear Ola,

ok, now it's starting to make more sense. Our server was first installed 
in 2012 (Beta-4.3.3 - 4.4.2), and since then we've always upgraded it 
very easily by just changing the path to the installation directory in 
all relevant scripts. So far it worked without any problems, but now we 
need to do more.

One thing I noticed is that we need Python 2.6. Our server is RedHat 5, 
with Python 2.4 as default. I can install Python 2.6 separately, but I 
don't know how to set it as system default. I tried simple way by 
replacing /usr/bin/python with a link to /usr/bin/python26, but that 
upsets yum that needs the old version. Is there some way to tell OMERO 
which Python to use?

Your Linux server documentation is for Ubuntu/Debian. Is that also the 
preferred platform for OMERO? Do you develop/test on any other Linux 
distributions?

How does the OMERO upgrade from version 4 to 5 work, would it be 
possible to create a Ubuntu server with fresh OMERO 5, initialize 
database from a dump and then configure OMERO to use the existing 
storage disk? At the moment we have also servers for backing up the 
database, for concistency it'd probably be good to reinstall also those 
on Ubuntu. All in all this would be quite a bit of work, but it might be 
worth it if it helps make the system more future-proof. At the moment 
the university IT offers Ubuntu 12.04 LTS, and will offer the next LTS 
version when it becomes available.

Comments and suggestions are welcome :)

Best,
Harri
