Open Microscopy Environment

[solved]

Hi,

just as an information: After some time a working albeit rather unused OMERO installation could not be started anymore. The reason given in Blitz-0.log was that "Initializing Ice.Communicator" failed. Later on in the Blitz-0.log the error message claimed that:

Code: Select all

...[ome.services.blitz.util.BlitzConfiguration]: Constructor threw exception; nested exception is org.springframework.beans.FatalBeanException: Could not find Ice config for object adapter [ BlitzAdapter ]

In master.err I found the following:

Code: Select all

-! 06/13/16 17:23:02.173 OMERO.Glacier2: warning: unable to contact permissions verifier `BlitzVerifier@BlitzAdapters'
   Reference.cpp:1663: Ice::NoEndpointException:
   no suitable endpoint available for proxy `BlitzVerifier -t -e 1.1 @ BlitzAdapters'
-! 06/13/16 17:23:02.218 OMERO.Glacier2: warning: unable to contact session manager `BlitzManager@BlitzAdapters'
   Reference.cpp:1663: Ice::NoEndpointException:
   no suitable endpoint available for proxy `BlitzManager -t -e 1.1 @ BlitzAdapters'


A lot of googling finally dug out https://www.openmicroscopy.org/community/viewtopic.php?f=5&t=7797

In which I found the incantation to revive the OMERO installation:

config set Ice.IPv6=0

The reason for the problem was, that along moving into a new building I had to switch off IPv6 for the server completely. Without IPv6 configured on the network interfaces, OMERO fails to start with the above Ice::NoEndpointException.

Hope it helps others in similar situations.

Best regards,
Stefan
