How To Get Total Elapsed Time Of Multiple Queries
May 7, 2013I am executing below two SQL's at a time in a .sql file and I want the total execution time of these two queries:-
set timing on;
select 1 from dual;
select 2 from dual;
The output of the above sql file is returning the results like below which is expected:-
1
----------
1
Elapsed: 00:00:00.01
2
----------
2
Elapsed: 00:00:00.00
I want the total execution time of the two SQL queries at a time, I mean post execution of the two queries I want to know the total execution time, in this case is execution case will be 00:00:00.01.

Feb 6, 2013Is there any oracle dictionary view which captures the queries being run by users on the database and time taken to execute those queries?We need to find out the OS user not the database user since we have to identify the users who are executing long running queries.We require this basically to monitor the long running queries on the database.

On AWR, I see two script that are out of ordinary, and I want to make sure that I interpret them correctly.
1) "Elap per Exec (s)" shows 3263.49 with 1 "Executions".
2) "Elap per Exec (s)" shows 3180.17 each execution with 2 "Executions".
Does this mean that this script ran for ~ 54 minutes (3263.49 / 60 seconds) for 1 "Execution" and ~ 53 minutes (3180.17 / 60 seconds) per each execution? I need to understand "Elapsed Time (s),CPU Time (s),Executions ,Elap per Exec (s), % Total DB Time" represent.

Why the elasped time changed when data and plan hasn't changed at all? Also why the plan has different stats for round 1 and 2 on db1 and db2?
I ran it 2 times each round each database so hard parsing shall not be issue.Also why the number of rows accessed are different in db1,db2 and db3,db4 especially for step1 when count of crt.qtn_cun_id is similar?
In fact when the query was taking long I was the only user on the system Also I used hard coded value (no bind variables at all)
I checked num_rows, distinct keys as well which are quite similar across all 4 databases Also no stats where gather during the query execution
What I should have checked or monitored?

Mar 10, 2012Main Aim : To find all those id's who have taken all the tests within a rolling window of 45 days.
I have a table "MBS_FIRST_DATE" with the following data :This table has the patients who have the test along with the first date..This table is derived such that it has only one record with the first date of the test irrespective of the test.
create table MBS_FIRST_DATE
(
medical_record_number VARCHAR2(600),
requested_test_name VARCHAR2(39),
result_date DATE
[code]..
Process :will be explaining with a patient id :
1) Consider the patient 1001274 from mbs_first_date table.
2) This patient has an date of July 08th 2008 & test SBP from first table. (keep this test an an anchor).
3) For the patient above loop through the all_recs table with test & result date ordered for the patient. (excluding SBP)
4) The first record we have is CHL with 08/05/2009 (May 8th 2009)..
5) Since this record is not within 45 days from SBP date for the patient..we go to the next record of SBP for the patient.
6) The next record for SBP is 11/05/2009 (May 11th 2009) .
7) Consider the CHL date again which is with 08/05/2009 (May 8th 2009)..
Since both are within 45 days ..store both the values keeping SBP date as an anchor date as it's the test that's having minimum date from table 1. Even though there is one more CHL date which is within 45 days from SBP we don't care about it.
9) Go to the next test for the same patient which is DBP..
10) The DBP first date is July 08th 2008..
11) Since it's not within 45 days from previously stored SBP date (11/05/2009) ignore the record.
12) GO to the next record which is 10/05/2009..as this is within 45 days from SBP & already CHL (stored date) is within 45 days..Grab all the 3 dates as all are within 45 days from anchor date (SBP date).
SO the o/p will be
1001274 SBP 11/05/2009
1001274 CHL 08/05/2009
1001274 DBP 10/05/2009
Code which I wrote :I know some where I am missing the loop
declare
V_ID1 VARCHAR2(200) := '';
V_TEST1 VARCHAR2(200) := '';
V_DATE1 DATE := NULL;

SQL Queries Taking Long Time After 11g Data Migration
Sep 14, 2010I have upgraded oracle database from 9i to 11g using export and import utility. After migration we are facing performance issue in report generation, We have observed that First execution of report is taking very long time and when we generate the same report 2 -3 times there is considerable change in the execution time and it is more better than the first execution.
2 days back I have restarted the database and found the same issue. There are around 300 Reports and it is not possible to generate all the reports 2-3 times every time we restart the database.

Mar 28, 2012I wanted to calculate the time variance dynamically as below.I have one table called process_status where we can see the process name, start time, end time and the status .
1. Now i wants to calculate the duration(end_time - start_time) in hh:mi:ss format and i got the output using below query.
select name, start_time, end_time, status, to_char(trunc(sysdate) + (end_time - start_time), 'HH24:MI:SS') duration from process_status ;
I got currect oupput but i am stuggling with the below step.
2). Actually the process expectaiotn time is 2 hours only(fixed time). Now i wants to calculate variance b/w expected time and the duration time(end_time - start_time)
i.e variance = expected_time - (end_time - start_time ) ;
here expected time is 02:00:00(fixed).

in the above, for job 1 ,on 19/08/2010 the time difference should be calculated as
