Cause: An attempt was made to resume a distributed transaction branch that is physically located on another RAC instance.

ORA-24798错误指示无法恢复在另一个实例上的分布式事务分支。该错误指示不同事务的全局事务ID无效或重复。

Oracle官方解释ORA-24798指出:“ORA-24798:在另一个实例上无法恢复分布式事务分支”

ORA-24798错误常见于使用RAC(Real Application Clusters),其中一个实例可能重新开始事务,从而导致全局事务ID重复或无效。此外,在使用错误的跨实例提交时也可能出现此错误。

正常的处理方法及步骤则要求用户首先检查全局事务ID是否重复或者无效,然后停止此服务,重启具有重复事务ID的实例,并将所有cablock分支的状态设置为Cancel。接着,释放所有事务ID,删除具有重复事务ID的分支,并尝试重新启动服务。
