> We sometimes add VDB to a controller with the 'force' intialization flag even
> if the VDB might be the 'last man down'.
> If the VDB was the 'last man down' the we get a 'Unique Constraint Violation'
> Exception because the
> org.continuent.sequoia.controller.xml.DatabaseParser class ALWAYS inserts the
> 'last-man-down' checkpoint if
> the 'force' flag was used but the VDB could possibly have a 'last-man-down'
> checkpoint.
> Solution is to always clear the 'last-man-down' checkpoint when add the
> virtual database with the 'force'
> flag set.
