Markus M. May commented on OFBIZ-3557: -------------------------------------- Are we the only one experiencing this problem? We still experience this problem, even with the suggested solution to use require-new-transaction="true" on the getNextInvoiceId-Service. There are a couple of solutions in my head (like e.g. use the database sequence directly), but these are not really a solution for such a "common" problem. Any help on this one is greatly appreciated. > Enforced sequence does not work with concurrent access > ------------------------------------------------------ > > Key: OFBIZ-3557 > URL: https://issues.apache.org/jira/browse/OFBIZ-3557 > Project: OFBiz > Issue Type: Bug > Components: framework > Affects Versions: Release Branch 09.04, SVN trunk > Reporter: Wickersheimer Jeremy > Attachments: OFBIZ-3557-1.patch, OFBIZ-3557-2.patch > > > There is a fundamental issue with enforced sequences (for orders, invoices, > etc ..) and concurrency. > For example if two users are creating an order at the same time one of them > will see the creation fail with a PK error. The problem is that the > "getNextXXXId" rely on the party accounting preference entity, but there is > absolutely no guarantee that the last number in the sequence gets updated > before another service can read it. > This is at best very annoying when used only internally but may be > unpractical for e-commerce sites. -- This message is automatically generated by JIRA.
