[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-2806) Enhanced TableGenerator is not cluster-safe on MySQL (does not use correct table type)

Enhanced TableGenerator is not cluster-safe on MySQL (does not use correct table type) -------------------------------------------------------------------------------------- Key: HHH-2806 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2806 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: Mac OS X 10.4.10 (Intel), Java 1.5.0_07, MySQL 5.0.24a Reporter: Matt Solnit The org.hibernate.id.enanced.TableGenerator.sqlCreateStrings() method does not include a call to Dialect.getTableTypeString(). This means that on MySQL, it will +always+ use MyISAM, even if the Hibernate dialect is "MySQL5InnoDBDialect". The result is that the FOR UPDATE lock has no effect, and the generator is not cluster-safe. In other words, multiple Hibernate applications can receive the same ID and get a primary key violation.
