Dear Sequoia Users,
We currently use Apache Derby for the backends in our distributed
Sequoia 2.10.9 cluster and Hypersonic for the Sequoia recovery log.
Now we hear that their have been problems with HsqlDb in productive
environments and also of the suggestions to limit memory usage via the
URL settins (which we have included in our environment). Therefore we
would like to move the Recovery Log to Derby.
My question is : does anyone use Derby for the Recovery Log. If so,
how do you configured the database columns and keys in the VDB XML?
I'm asking this as we have critical problem that Derby can take hours
to check a reasonably sized (200,000 rows) recovery log...
Many Thanks in Advance,
Nick
p.s. Does anyone know if the upcoming 2.10.10 release will still insert
select statements into the recovery log? Our applications does 98%
selects and 2% inserts/updates...
