Note
This documentation is for the new OMERO 5.2 version. See the latest OMERO 5.1.x version or the previous versions page to find documentation for the OMERO version you are using if you have not upgraded yet.
On each startup the OMERO server checks for available upgrades via the UpgradeCheck class. An HTTP GET call is made to the URL configured in etc/omero.properties as omero.upgrades.url, currently http://upgrade.openmicroscopy.org.uk by default (note that viewing that link in your browser will redirect you to this page).
Note
If you have been redirected here by clicking on a link to http://upgrade.openmicroscopy.org.uk in an error message or log while trying to run one of the Bio-Formats command line tools, please see the Bio-Formats command line tools documentation for assistance.
Currently the only action taken when an upgrade is necessary is a log statement at WARN level.
2011-09-01 12:21:32,070 WARN [ ome.system.UpgradeCheck] ( main) UPGRADE AVAILABLE:Please upgrade to 5.2.3 See http://trac.openmicroscopy.org.uk/omero for the latest version
Future versions may also send emails and/or IMs to administrators. In the case of critical upgrades, the server may refuse to start.
Currently, the only information which is being transmitted to the server is:
Note
Currently the “poll” property is unused.
If this is a problem for your site, please see Disabling below.
If you would prefer to have no checks made, the check can be disabled by setting the omero.upgrades.url property to an empty string:
omero.upgrades.url=
To use the UpgradeCheck class from your own code, it is necessary to have common.jar on your classpath. Then,
ResourceBundle bundle = ResourceBundle.getBundle("omero")
String version = bundle.getString("omero.version");
String url = bundle.getString("omero.upgrades.url");
ome.system.UpgradeCheck check = new UpgradeCheck(
url, version, "insight"); // Or "importer", etc.
check.run();
check.isUpgradeNeeded();
// optionally
check.isExceptionThrown();
will connect to the server and check your current version against the latest release.
