elapsed_time in v$sql

edited Jul 13, 2017 10:15AM in Database Tuning (MOSC) 5 commentsAnswered

Hello,

I have noticed that some statements don't have their elasped_time equals to CPU_TIME + APPLICATION_WAIT_TIME + CONCURRENCY_WAIT_TIME + CLUSTER_WAIT_TIME + USER_IO_WAIT_TIME + PLSQL_EXEC_TIME+ JAVA_EXEC_TIME

How can I find out where the remaining time is spent ?

Example

Database: 11.2.0.4.0

OS: AIX

ELAPSED_TIME = 4301515700

USER_IO_WAIT_TIME + CPU_TIME = 2668272184

USER_IO_WAIT_TIME + CPU_TIME / ELAPSED_TIME = 64% ---> where are the remaining 36% ?

Thanks in advance,

Howdy, Stranger!
