OMERO Process Container Steward

Tools for stewardship of the OMERO server ProcessContainer.

Requirements

The latest release, built by GitHub Actions, can be found here:

It can also be build by hand:

    git clone git@github.com:glencoesoftware/omero-pc-steward.git
    cd omero-pc-steward
    ./gradlew jar

Copy the downloaded .jar or the built one from build/libs into the $OMERODIR/lib/server directory of your OMERO installation
Configure logging by adding <logger name="com.glencoesoftware" level="INFO"/> to the "ROOT logger" section of $OMERODIR/etc/logback.xml
Optionally, configure the frequency of the cleanup checks by setting the config omero.managed.steward.cron to a valid cron string (see https://www.quartz-scheduler.org/api/1.8.6/org/quartz/CronExpression.html). The default is set to check every minute for completed import processes to clean up. If you wanted to check every 30 seconds, you could set
```
 omero config set omero.managed.steward.cron '*/30 * * * * ?'
```
Restart OMERO server with
```
 omero admin restart
```
In $OMERODIR/var/log/Blitz-0.log, you should see logging from the ProcessContainerSteward once per configured period (default every minute) reporting how many ImportProcesses there are in the ProcessContainer
