Validating Data and Index Integrity

[Si...@saaconsultants.com]

Following a few power failures and unexpected terminations of the VM
(careless operators!) we have experienced corruptions of the directory JDBM
backed store.

In all cases, the DS shutdown hook was never executed.

Is there a way we can run an integrity check on the content of the JDBM .db
and .lg files - either at a low level or via a DS API call?

We could then run this "integrity check" when we detect an uncheduled
shutdown when restarting...

TIA

We should have a db dumber in apacheds-tools. It's in $APACHEDS_HOME/bin.

You can invoke it like:

./apacheds-tools.sh dump -i $APACHEDS_HOME -f dump.dat -p 'system'

"./apachedstools.sh help dump" will give more information.
