检查dba_2pc_pending的state列，如果是commited，意味着本地数据库提交已经成功。其他节点需要根据本地事务号和最大的commit#进行强制提交。用法如下：

       SVRMGR> COMMIT FORCE 'your local transactionID on this node', 'highest SCN from already committed site';

       SVRMGR> COMMIT FORCE '1.13.5197', '88123887';

如果commit point site的state为 commited 外的其他状态，则表明commit point site 没有提交成功，分布式事务需要强制回滚。这里不再需要所有节点的最大commit#。用法如下：

       SVRMGR> ROLLBACK FORCE 'your local transactionID on this node';

       SVRMGR> ROLLBACK FORCE '1.13.5197';
