[ome-devel] Omero 4.2.0 questions: 64bit support and upgrading of BioFormats

[Alessandro Dellavedova]

Hi Chris,

>> we are currently  deploying OMERO 4.2.0 under Solaris 10 and we'd like to exploit the 64bit architecture of the machine that is hosting OMERO.
>> 
>> Will you please confirm that these are the steps needed in order to run a 64-bit version of OMERO:
>> 
>> - Install the 64bit JRE/JDK;
>> - Compile the 64bit version of ICE 3.3.1;
>> - Modify /opt/omero/etc/grid/templates.xml in order to pass the -d64 option to Blitz, Indexer and Repository.

Good, we'll try to run OMERO with the -d64 flag and then we'll report here what happens.

Since the import of those AVI files is quite important for us, I'd like to ask what's the best way to upgrade our OMERO 4.2.0 server and clients in order to include the fix.

This is a very good news, so we will replace the installed clients and make our Imaging facility users happy.

>> I've also read the message about Maven and LOCI BioFormats, can this ease the upgrade of OMERO 4.2.0 ?

> It's largely a developer change at this point so no it won't be affecting the ease of upgrading OMERO 4.2.0.

That's fine, thanks for your time.
