L.S., I'm sitting currently on a piece of code that might be of more interest to others. It is a consistency checker of the jackrabbit on-disk structure. It is not that such a piece of software in needed daily for a Jackrabbit JCR. In general usage, I've not been able to trap Jackrabbit on being able to corrupt its own persistent storage. But like all things, sometimes things still go wrong, especially when confronted with external influence. Restoring lucene indexes which don't represent the datastore, misbehaving extensions. In any case you do want a consistency to just be sure all data is still in a consistent state.
Now the consistency checker in jackrabbit does check a number of items, but we've actually ran into issues that were not picked up by that consistency check but still represented a bad state. I've also found that having to set multiple constency check flags to true in multiple files (located in the storage self) is not the easest way to instruct third party sysadmins. A fast stand alone consistency check has a place there. Like I started, the piece of code developed might be of interest to more people, and it is open. Sure it's not finished (it currently only does MySQL backends, repairs are disabled and could do with a clean up). But it is already in a state where it scans on-disk structures quite thoroughly and is very fast. Because it is stand-alone it can be both more thorough and faster than the built-in consistency checker (much more thorough check done in 5 minutes rather than many hours). You can check it out under: http://svn.hippocms.org/repos/hippo/hippo-ecm/repository/trunk/checker It should build out of the box (not needing any subprojects from the parent project it is in. And I'll put a README with more into the project in not too long. Improvements will be made over a short time frame, but I'd like to have some feedback and like said, its open for general use. \Berry
