Open Microscopy Environment

Hi all, this has been an interesting journey to even attempt to get this to work. I'd appreciate any help on getting this last bit through

So, as the title suggests, I'm installing this in Win Server 08, SP2 32 bit. I have installed IIS 7 using default services selected in addition to CGI, ISAPI extensions and filters.
The omero server is started and the database was created, and I registered it to http://localhost:80/
When I go to this page in either IE or Chrome the first time per system restart, it shows the super helpful error:
"A server error occurred. Please contact the administrator."
If I then try to go to the page again, it takes a god awful long time spinning, and then pretty much sits there.
These are the settings used:

Code: Select all

C:\omero_dist\bin>omero config get
omero.web.application_host=http://localhost:80/
omero.web.application_server=fastcgi-tcp
omero.web.cache_backend=file//C:/windows/temp
omero.web.session_engine=django.contrib.sessions.backends.cache

I installed PostgreSQL 8.3
Java JDK SE 7u3
Ice-3.3.1-VC80
ActivePython 2.5.6.10
PIL: 1.1.7

Thanks for any troubleshooting ideas!

Hi, Could you attach logfiles from OMERO_DIR/var/log

Thanks

Browsed through it while uploading and maybe this is the error that is important?:

Code: Select all

Tue, 20 Mar 2012 01:59:04 omero.util.TempFileManager ERROR    rmtree error: remove('C:\Users\Administrator\AppData\Roaming\omero\tmp\omero_Administrator\3032\.lock') => [Error 32] The process cannot access the file because it is being used by another process: u'C:\\Users\\Administrator\\AppData\\Roaming\\omero\\tmp\\omero_Administrator\\3032\\.lock'

I have no idea what this even means, much less fix it

Thanks

HI Brian

This may be caused by not being able to properly delete files from the roaming directory. Can try to use TempFileManager (http://trac.openmicroscopy.org.uk/ome/w ... ileManager) to point it somewhere else.

Thanks

Hmm, so I moved it, didn't seem to help unfortunately. The error doesn't reappear though, so there has been progress.
I tried to use the development server instead of IIS to see if that was the problem or if the underlying settings is screwed up. Apparently something is:

Code: Select all

C:\omero_dist\bin>omero config set omero.web.application_server development

C:\omero_dist\bin>omero config set omero.web.session_engine "django.contrib.sessions.backends.cache"

C:\omero_dist\bin>omero config set omero.web.cache_backend "file:\\C:\windows\temp\"

C:\omero_dist\bin>omero web start

Might this shed some light on the problem?

Hi,

Apologies for the delay. Cache backed settings should be:

Code: Select all

C:\omero_dist>bin\omero config set omero.web.cache_backend "file://C:/windows/temp/"


you missed : behind file

Ola

Sorry I was comparing with your first configuration setup

Referring to your last post

Code: Select all

C:\omero_dist\bin>omero config set omero.web.cache_backend "file:\\C:\windows\temp\"

You need to use forward slashes

Code: Select all

C:\omero_dist>bin\omero config set omero.web.cache_backend "file://C:/windows/temp/"

Hope that helps
Ola

Ahhhhh, such a stupid mistake that I didn't notice. I put this on the backburner because I hit a brick wall. Works now
Thank you!
Also this reminds me of this:
