-------------------------------------

     Assign To: Stephane Giron  (was: Robert Hodges)

As recovery can simultanously happen on several backends hosted by the same 
controller, the previous fix can show following NPE :

2008-02-06 11:05:14,628 WARN controller.virtualdatabase.nrejp_db Virtual 
database nrejp_db failed to enable database backend db201-b2 from checkpoint 
(because of : java.lang.NullPointerException)

>      Project: Sequoia
>         Type: New Feature

>     Versions: Sequoia 2.10.9
>     Reporter: Stephane Giron
>     Assignee: Stephane Giron
>      Fix For: sequoia 2.10.10

>
>
> Some commands require the vdb to suspend its activity.
> For some reasons (bugs, ...), the vdb can remain in this suspended state 
> forever, blocking the whole activity.
> We should investigate if it is possible in such a context to provide a 
> console command that will force the vdb to resume the activity.
