SQL & PL/SQL :: Know Execution Time Without Running Query?
Jul 13, 2008Is there a way to know how much time will a query take to execute without running it, just like using the autotrace (traceonly) and explain plan utility.
View 16 Replies View RelatedUnusual High Query Execution Time?
Aug 25, 2010I am facing a very strange issue with one of our Oracle query. The query is usually completes in a minute or two. Even the execution plan of the query is good and it works perfect most of the times, as expected. The query fetches about 1000-2000 records each day.
But on a given day, the query takes about 30-40 mins to execute completely. Upon checking the load on DB server, there are no other processes running which can impact the run time of this query. Moreover, the record counts fetched are almost same as compared to other days. There is no pattern observed as that this phenomenon occurs. it all happens once in a while.
Configuration is Oracle 10g with RAC environment on LINUX

Jul 6, 2012I have huge package having numerous procedures. Therein there is one wrapper procedure which is invoked from front end and which in turn calls other stored procedures within the package. The stored procedures called return the result to the wrapper procedure which in turn calls other stored procedures.
The ultimate result is returned to the calling environment by the wrapper procedure itself.I need to know the time taken in totality by the wrapper procedure along with the individual execution time of each procedure called by the wrapper procedure. I am not allowed to modify the code for adding timestamp capturing though.
Performance Tuning :: Lost Index From Second Execution Time?
Jul 11, 2013The problem was describe:

Now, I show the objects and relate information here:

Performance Tuning :: Delete Statement Is Taking More Time For Execution?
Mar 9, 2010In my code I am using delete statement which is taking too much time to execute.
Statement is as follow:
DELETE FROM TRADE_ORDER_EMP_ALLOCATION T
WHERE (ARTEMIS_SOURCE_SYSTEM_ID,NM_ARTEMIS_SOURCE_SYSTEM,CD_BOOK_KEY,ACTIVITY_DT)
IN (SELECT ARTEMIS_SOURCE_SYSTEM_ID,NM_ARTEMIS_SOURCE_SYSTEM,CD_BOOK_KEY,ACTIVITY_DT
FROM LOAD_TRADE_ORDER
WHERE IND_IS_BAD_RECORD='N');
Tables Used:
oTRADE_ORDER_EMP_ALLOCATION Row count (329525880)
oLOAD_TRADE_ORDER Row count (29281)
Every column in "IN" clause and select clause is containing index on it
Every time no of rows which to be deleted is vary (May be in hundred ,thousand or hundred thousand )so that I am Unable to use "BITMAP" index on the table "LOAD_TRADE_ORDER" column "IND_IS_BAD_RECORD" though it is containing distinct record in it.
Even table "TRADE_ORDER_EMP_ALLOCATION" is containing "RANGE" PARTITION over it on the column "ARTEMIS_SOURCE_SYSTEM_ID". With this I am enclosing table scripts with Indexes and Partitions over it.
way for fast execution in of above delete statement?
PL/SQL :: Oracle Dictionary View 2 / Find Queries Run And Its Execution Time
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.

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?

Jun 6, 2013I have the below query for which ename column has an index. As of my knowledge below queries 1st and 2st will not use index. Hence i used the 3rd statement and that too its not using the index. Finally i used the 4th query, but even the 4th query is not using the index. Then how do i make this query to use my index??? Do i need to create a function based index for this?
1. select * from emp where ename !='BH' ;
2. select * from emp where ename <> 'BH';
3. select * from emp where ename not in ('BH');
4. select * from emp where ename < 'BH' or ename > 'BH';

If you are not getting then take an example of department and employee datablocks, first contains the info of department and second contains the employee info working in that department.
now what i want to do is to make the life of user easier, as the records are displaying properly so if user want to know that this record is present in the details of that header so while scrolling all records can he search by putting some info in the detail block to get that result while remaining on the same datablock?
