Ice 3.4 vs. 3.3?

[vangale]

We're still struggling with trying to run OMERO Server 4.2 without tons of errors in the Blitz logfile and I'm just wondering... maybe Ice 3.4.1 is now required base version instead of 3.3.1 as documented?

Thanks,
Van

Definitely not. We don't support Ice 3.4 at present. If you attach the Blitz-0.log here we can try and help you understand why you're getting the errors.

Sure, the Blitz logfile is in the last post to this thread: viewtopic.php?f=5&t=451

Our current thinking is it's an OpenJDK vs. Sun JDK issue, because we're getting fewer errors with Sun JDK and they aren't threadpool type problems.

Thanks!

Van,

can you describe what the latest symptoms of your server errors are? The logfile that you posted seems completely clean. There are three ERRORs in that file:

2010-09-01 15:08:59,442 -- This is a failure to contact the UpgradeCheck and can safely be ignored. This may be an issue with your firewall, or perhaps our server was temporarily down.

2010-09-01 15:17:48,816 -- This and the next error are caused by an attempt to close a session while the server is already being shutdown, i.e. someone called bin/omero admin stop or similar.

Hope this is helpful.

Hi Josh,

Thanks for the response. I am the only admin doing start/stop so this was not causing the error. We had very similar error messages when NFS was configured incorrectly.

Anyway, if this error happens again I will post a new logfile. Current logfile is clean (except for the updatecheck of course) after we did the full migration of our database from 4.0 to 4.2.

Thanks!

It's been a while since release of Ice-3.4. Now most of linux (and MacOS) distributions come with this version in their repositories. Isn't it time to make OMERO compatible with Ice-3.4? It's a real pain to install OMERO on a new server as it depends on older unsupported packages.

It has been a while yes. One of the reasons we haven't made an explicit upgrade to Ice 3.4.x across the board is that the two most common Linux distributions don't come with this version of Ice. ZeroC kindly provides RHEL/Centos Yum repositories for several versions of Ice (including 3.3.x) as it doesn't come with the distribution and Ubuntu, for which Ice is included is still at 3.3.1.

The odd platform out really is Mac OS X, and Glencoe Software has kindly provided a complete pre-compiled binary Ice 3.3.1 distribution that is linked off the UNIX platform install page.

All this said we do intend, with OMERO Beta 4.3.0 to support Ice 3.4.x and potentially both 3.3.x and 3.4.x Ice distributions. If you want to track the status of the upgrade in Trunk you can do so here:

Thank you for a quick reply.
Just wanna note that RHEL/Centos do not include any version of Ice in their repos. And ZeroC has both versions for RHEL. On the other hand Fedora (which is basically same redhat, just a bit less stable) has version 3.4.0 in their default repo and no 3.3.x anymore.

Anyway, am looking forward to see a new version of Omero next year. Thank you and have a great holidays!
