Subject Derby server health probing
Date Tue, 23 Aug 2005 14:13:04 GMT

We use a derby server in an High Availability context. Thus, we need to 
test if derby server is in a good shape or not. The result of this 
repetitive question will imply a fail-over or not.

we thought about two solutions:

1/ create an agent to insert/select/delete an entry in a table
2/ create a stored procedure doing a finer job.

these solutions do not satisfy us as:

o a JVM needs to be created for a very short duration and repetitively
o it's CPU consuming.

So, do you think of another solution that would prove the derby server 
is in a good shape, without consuming too much resources.
