Oracle 视图 V$DYNAMIC_REMASTER_STATS 官方解释,作用,如何使用详细说明
本站中文解释
V$DYNAMIC_REMASTER_STATS是Oracle的一个视图,位于X$KRSBS 表上,用来显示动态重新定位操作的状态计数,其中包括了重新定位块总数、重新定位失败的块数、重新定位超时的块数等等。通过V$DYNAMIC_REMASTER_STATS可以查看动态重新定位操作执行的情况,确保动态重新定位操作正确执行,以提高存储引擎性能。
使用V$DYNAMIC_REMASTER_STATS视图的方法:
首先,进入SQL*Plus命令行,然后在SQL查询窗口中输入如下语句,以查询动态重新定位操作的状态计数:
SELECT * FROM V$DYNAMIC_REMASTER_STATS;
这将显示出动态重新定位操作的状态计数,如重新定位块总数、重新定位成功的块数、重新定位失败的块数、重新定位超时的块数等等。
以上就是关于Oracle视图V$DYNAMIC_REMASTER_STATS及其用途以及使用步骤的详细介绍。
