Oracle 视图 V$GES_CONVERT_REMOTE 官方解释，作用，如何使用详细说明

本站中文解释

就是oracle 10g新增的视图，它是全局事务服从者和服从协调器比较常用的几个视图之一。

V$GES_CONVERT_REMOTE是管理要进行XA转换的远程分布式事务的视图。它显示了要实施提交服从的分发式内部事务的信息，包括状态，事务的XID等等。其中的一些转换可能由于网络连接断开而失败，这样V$GES_CONVERT_REMOTE可以用来重新恢复这些转换，也可以用来清楚失败的会话，以释放（以及回滚）在远程数据库上的地锁。

要使用V$GES_CONVERT_REMOTE，首先要在相关的实例上启起分发式服从跟踪。应该注意的是，如果在Oracle数据库中启起了应用服从，但要么未在分发式环境下启起，要么未启起相关的分发式服从跟踪，则V$GES_CONVERT_REMOTE视图将无法使用。

官方英文解释

V$GES_CONVERT_REMOTE displays values for remote GES enqueue conversions. This view records average convert times, count information, and timed statistics for global enqueue requests.
