I did not notice your remarks about prepared statement and DB hits, I was only considering the legibility, trying to understand what Adrian wants to add. Having a test is really a plus, thank you for that! > SequenceUtil may generate duplicate IDs in Load Balancing mode > --------------------------------------------------------------- > > Key: OFBIZ-2353 > URL: https://issues.apache.org/jira/browse/OFBIZ-2353 > Project: OFBiz > Issue Type: Bug > Components: framework > Affects Versions: Release Branch 4.0, Release Branch 09.04, Trunk > Reporter: Philippe Mouawad > Assignee: Jacopo Cappellato > Priority: Critical > Fix For: Release Branch 10.04, Upcoming Branch > > Attachments: OFBIZ-2353 SELECT FOR UPDATE solution.patch, OFBIZ-2353 > SELECT FOR UPDATE solution.patch, OFBIZ-2353-AC.patch, OFBIZ-2353-AC.patch > > > If Ofbiz is deploy on 2 servers in Load Balancing Mode > SequenceUtil will generate duplicate IDs because synchronization is done at > JVM level instead of doing it in DB. > A good replacement implementation would be: > org.hibernate.id.enhanced.TableGenerator > But it would involve a dependency on Hibernate > Philippe > www.ubik-ingenierie.com -- This message was sent by Atlassian JIRA (v6.3.4#6332)
