最近我的应用程序JPA / Hibernate中出现了以下错误,数据库为Oracle RAC 11g。
当我们的存储空间已满并且DBA需要关闭连接,杀死活动会话或某些类似“连接已关闭”(现在我可以知道发生了什么,他被解雇了......)时发生了此错误。

与其他DBA交谈他说来自Oracle的一个实例获得了完整的磁盘,并且此时创建了部分提交的寄存器,但他刚刚删除了跟踪文件,没有停止db而不是杀死任何会议。
答案 0 :(得分:1)
嗯,没有足够的信息可以肯定地说,但听起来就像你看到它没有完成的交易处理。 JDBC规范默默地讨论了在未完成的事务中应该发生什么的问题。 Oracle是我所知道的唯一一个决定最佳行动方案的供应商,就是在这种情况下承诺工作。
