今天就跟大家聊聊有关常用的Oracle 11g内存视图脚本有哪些，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。
今天主要分享几个关于Oracle数据库的内存视图的脚本。
一、V$MEMORY_DYNAMIC_COMPONENTS
V$MEMORY_DYNAMIC_COMPONENTS displays information about the dynamic SGA components. This view summarizes information based on all completed SGA resize operations since instance startup. All sizes are expressed in bytes.
脚本： Provides information about dynamic memory components.
COLUMN component FORMAT A30 SELECT component, ROUND(current_size/1024/1024) AS current_size_mb, ROUND(min_size/1024/1024) AS min_size_mb, ROUND(max_size/1024/1024) AS max_size_mb FROM v$memory_dynamic_components WHERE current_size != 0 ORDER BY component;
二、V$MEMORY_RESIZE_OPS
V$MEMORY_RESIZE_OPS displays information about the last 800 completed memory resize operations (both automatic and manual). This does not include in-progress operations. All sizes are expressed in bytes.
脚本：Provides information about memory resize operations.
SET LINESIZE 200 COLUMN parameter FORMAT A25 SELECT start_time, end_time, component, oper_type, oper_mode, parameter, ROUND(initial_size/1024/1024) AS initial_size_mb, ROUND(target_size/1024/1024) AS target_size_mb, ROUND(final_size/1024/1024) AS final_size_mb, status FROM v$memory_resize_ops ORDER BY start_time;
三、V$MEMORY_TARGET_ADVICE
V$MEMORY_TARGET_ADVICE provides information about how the MEMORY_TARGET parameter should be sized based on current sizing and satisfaction metrics.
脚本3： Provides information to help tune the MEMORY_TARGET parameter.
SELECT * FROM v$memory_target_advice ORDER BY memory_size;
