今天看awr,在等待时间中除了两个没见过的,网上查了下不太明白,不知道有没有大神能帮忙解释下
db file sequential read 和read by other session ,还有就是虽然昨天没看成刘大的视频但是看文档发现,好像sql这边的解析有问题
awr中部分
Statistic Name Time (s) % of DB Time
Parses: 269.38 46.69
Hard parses: 4.56 0.79
Statistic Name Time (s) % of DB Time
parse time elapsed 2,310.85 4.43
hard parse elapsed time 2,268.13 4.35
PL/SQL execution elapsed time 1,538.56 2.95
hard parse (sharing criteria) elapsed time 38.10 0.07
PL/SQL compilation elapsed time 29.22 0.06
hard parse (bind mismatch) elapsed time 4.09 0.01
不知道我的怀疑对不对,望大牛们指点一二
下面sql中是不是也都是问题比较大的?- Elapsed Time (s) CPU Time (s) Executions Elap per Exec (s) % Total DB Time SQL Id SQL Module SQL Text
