Christ.
I was working and playing with some settings on an Alfresco server to try and harden it security-wise. BIG mistake. I couldn’t get the bugger to start up afterwards. With other work commitments in the way, it’s been down for about a day now. I’ve tried downloading the BETA of Alfresco Labs and read various forums with no joy.
The error was
org.alfresco.error.AlfrescoRuntimeException: A previous schema upgrade failed. Revert to the original database before attempting the upgrade again.
FINALLY I found the solution at Bits n Bobs. It’s ridiculously simple: drop the table alf_bootstrap_lock and restart the server.
Now to deal with the next crisis.
