多少 CPU 会话在 oracle 中的给定时间消耗
how much CPU a session consuming at a given time in oracle
我正在寻找一个 script/process 来检查每个查询在我的 oracle 数据库中任何时间点消耗的 CPU 的数量（以百分比表示）。
我的 Oracle 版本是：12.1.0.2
数据库托管在 Exadata X7_2
它是共享服务器，许多数据库也在同一台服务器上运行。
SELECT AVG(value/vp.cpu_count) FROM v$sysmetric_history,(SELECT value cpu_count FROM v$parameter WHERE name LIKE 'cpu_count') vp WHERE metric_name = 'CPU Usage Per Sec' AND group_id = 2 AND end_time > SYSDATE - 10/(60*24) AND end_time <= SYSDATE;
我正在使用此脚本计算给定时间的实例 CPU 利用率。现在，我想知道每个 SQL 查询在给定的 CPU.
中消耗了多少
示例：在给定时间，如果我的 CPU 利用率是 80%，我想看看每个 sql 查询在这 80% 的实例中贡献了多少 CPU CPU.
要回答这个问题，您需要历史性能指标。获得这些的最简单方法是从 AWR 视图 DBA_HIST_SQLSTAT [需要许可证]（也可以使用 StatsPack）。至于获得百分比，您需要从总可用量 CPU 中计算出该百分比，但可能只需按 CPU 消费量订购就足够了。我从 AWR 表中使用的查询：
