mass inserts
When we do a lot of inserts at once, it seems like OJB does a lot of
"pre-querying". I think this is for deciding whether a new object
consistutes an UPDATE or an INSERT. For mass-loading of objects
(which we know will be new unique INSERTS). Is there anything we could do
to optimize the process? Prevent it from pre-querying?
Will proxies help by quickening the queries?
Any pointers welcome.

Hi Chuck,
Could you post a little more info.
Which OJB version?
Which sequence manager implementation do you use, or
post your repository_database.xml file (if you use one).
regards,
Armin

auto_increment problem?
Posted by Chuck Grohowski <ch...@hubcitymedia.com>.
I noticed a strange anomaly when using OJB with auto_increment fields in
MySQL. After doing a few inserts of new objects, the auto_increment field
has values in the hundreds. Is this behavior normal or is there something
going awry?
Any help is appreciated. Thanks!
Chuck
