Very useful for comparing performance of different implementations. CPU_TIME: NUMBER: CPU time (in microseconds) used by this cursor for parsing, executing, and fetching: ELAPSED_TIME: NUMBER: Elapsed time (in microseconds) used by this cursor for parsing, executing, and fetching: OUTLINE_SID: VARCHAR2(40) Outline session identifier: LAST_ACTIVE_CHILD_ADDRESS: RAW(4) This first post is pretty basic, yet core fundamental stuff. Script Name Elapsed Time Calculator; Description This simple package uses DBMS_UTILITY.GET_CPU_TIME to calculate the elapsed time, down to the hundredth of a second, of code execution. Area PL/SQL General; Contributor Steven Feuerstein (Oracle); Created Thursday May 11, 2017 and column TIMECOL have only DATE format? Answer: To retrieve the total elapsed time in minutes, you can execute the following SQL: select (endingDateTime - startingDateTime) * 1440 from table_name; Since taking the difference between two dates in Oracle returns the difference in fractional days, you need to multiply the result by 1440 to translate your result into elapsed minutes. Very useful for comparing performance of different implementations. When performing the below calculation (end_time minus start_time) in Oracle you get a result of +00 01:30:00.000000. BUSY_TIME- The total amount of time that the CPU was busy for the elapsed time period. NUM_CPUS - The number of processors available to the Oracle database As the elapsed time (time it takes for a task from start to end, often called wall-clock time) per execution of parallel queries are not shown correctly in AWR-reports, I thought I setup a testcase to find a way to get an elapsed time closer to reality. Viewed 3k times 0. This will exceed the wall-=clock time because we usually have multiple CPU's.
How can that result be converted to 1.50?
Since a full AWR report may not be necessary a script using some of the AWR data can generate elapsed time reports by sql_id. Active 5 years, 5 months ago. Convert elapsed time a decimal in Oracle. Ask Question Asked 5 years, 5 months ago. Area PL/SQL General; Contributor Steven Feuerstein (Oracle) Created Thursday May 11, 2017 Script Name Elapsed Time Calculator; Description This simple package uses DBMS_UTILITY.GET_CPU_TIME to calculate the elapsed time, down to the hundredth of a second, of code execution. The key Oracle Database time parameters are elapsed time, database time (DB Time), non-idle wait time and server process CPU consumption (DB CPU) time. As the elapsed time (time it takes for a task from start to end, often called wall-clock time) per execution of parallel queries are not shown correctly in AWR-reports, I thought I setup a testcase to find a way to get an elapsed time closer to reality. The formula for the Oracle elapsed time is as follows: Oracle elapsed_time metric = CPU time + user I/O wait time + application_wait_time + concurrency_wait_time + cluster_wait_time + plsql_exec_time + java_exec_time . SQL*Plus: Release 8.0.6.0.0 - Production on Ïòí Ñåí 1 15:13:14 2000 So in the following two posts I'll introduce elapsed time, add parallelism into the mix and revisit wall time. IDLE_TIME - The amount of time that the database was idle. With Oracle, the Automatic Workload Repository collects statistics on a regular schedule to report on how the system is performing, including elapsed time for queries. Can I change elapsed time format to HH:MI:SS ?
