SQl query are running slow in comparison to oracle 8i
Hi everybody,
I have two systems one is Oracle 9i on Windows 2000 and
one is Oracle 8i running on Windows 2000. The database structure is the same. When I run the following qry in
Oracle 9i
SELECT COUNT (a.aint_ac_no) AS total_ac_no, adet_int_rate,
SUM (fun_max_cbal_bal (a.aint_ac_no,
a.aint_subsys_cd,
TO_DATE ('30/01/2009', 'DD/MM/YYYY')
) AS balance
FROM domst120 a, domst730 b
WHERE a.aint_interest_slab_cd = b.adet_srno
AND a.aint_subsys_cd = '137'
AND fun_max_cbal_bal (a.aint_ac_no,
a.aint_subsys_cd,
TO_DATE ('30/01/2009', 'DD/MM/YYYY')
) <> 0
AND a.aint_eff_date =
(SELECT MAX (c.aint_eff_date)
FROM domst120 c
WHERE a.aint_bank_cd = c.aint_bank_cd
AND a.aint_branch_cd = c.aint_branch_cd
AND a.aint_bank_cd = '857'
AND a.aint_branch_cd = '6'
AND a.aint_subsys_cd = c.aint_subsys_cd
AND a.aint_ac_no = c.aint_ac_no)
GROUP BY b.adet_int_rate
ORDER BY b.adet_int_rate
it takes 6 min to complete.
the same qry running in Oracle 8i takes 2 seconds
to complete.
The index structure is same in both systems also the tables
were analyzed with compute statistics.
What do you expect?! Oracle 9i and Oracle 8i are different particularly by optimizer cost-based(9i) and rule-based(8i) :)
what about both execution plans?

Parallel hint causes a query to run slower?
I have an insert...select query where the select is a join between a table with one billion rows (although there is a where clause on an indexed column that restricts it to "only" 300 million), a table with 30 million rows, and a table with about 100,000 rows, where the result is about 20 rows. When I first ran it, it took about 2 hours. I added a Parallel hint, and explain plan showed that it was being used (and v$session showed that I had about 30 additional connections while it ran). but not it takes four hours.
Is there a reason parallel processing would cause a query to run slower?

One - I cannot find "Materialize" in the hints in the SQL Reference anywhere. What does it do?
Two - does replacing subqueries with With clauses make that much of a difference? -
Fetching queries that are running slow
Hi all,
Is there any tool in Oracle 9i, by which we can fetch queries that are running slow in the entire database on a weekly basis ?As mentioned, the statspack tables and the shared pool views from which they take their snapshots - V$SQL / V$SQLAREA - provided various ways for you to idenitify top N statements by cpu time, elapsed time, logical io, physical io, etc.
For a weekly basis, the statspack tables and statspack reports provided the easiest way to do this, a) providing you're capturing this data and b) depending on how long you're retaining it. -
How do I find out which query are running??
My client is connecting to the database and running application through the web. From the Unix system, I know his job took 99% of CPU time and running for 1 hour already. Is there anyway I can find out which query are running in the Oracle?? So I can tune this query?? thanks..
Hi,
You can use the following query to identify it.
set linesize 100
set pagesize 100
SELECT substr(sql_text,1,40) sql,executions, rows_processed,
rows_processed/executions "Rows/Exec",
hash_value,address
FROM V$SQLAREA WHERE executions > 100 AND rownum <= 10
ORDER BY executions DESC;

Executing PL-SQL Query before running a Report
Hi Guys,
Can i use a Run a Pl-Sql Query every time before executing a report. Like if i am opening a report then the pl-sql Query should run before it.
Thanks
Rondo.Try with Evaluate as one of the column's expression.. so that we can limit to specific report..
or
Use Connection Pool->Connection Pool Scripts tab->use 'Execute before query'
Since we can set the repository variables using advanced tab.. the same variable we may validate using Connection pool scripts tab.
This might be more dev work..

How to get report (SQL Query) generating Run Time
There is a Standard report of Payroll which show employee transfer information on the bases of location, grade job or organization, now to get actual query which is generated by run time in report builder including whether single column parameter or lexical parameter " because currently the query in not complicate but the parameter and lexical parameter is much more due to this not quite easy to under stand just copy past it into toad or pl/sql developer,
Kindly share your experience to get such kind of query in you working time.
thanksHere i try to explain contain of query.
Parameter
P_DEPTNO = 10
P_WHERE_CLAUSE := ' AND EMPNO IS NOT NULL AND SALARY > 100'
SELECT * FROM EMP
WHERE DEPTNO = P_DEPTNO
&P_WHERE_CLAUSE
REPROT WILL GENERATE QUERY AT RUN TIME IS LIKE THAT
SELECT * FROM EMP
WHERE DEPTNO = 10
AND EMPNO IS NOT NULL AND SALARY > 100
Now i want to get this query out(Run time) by doing any oracle database feature or sth similar.

Hi,
This delivers possibly wrong data in MCOD installations.
Depending on Oracle Version and Patchlevel dba_segments does not always have the correct data,
at any time esp. for indexes right after being rebuild parallel (Even in DB02 because it is using USER_SEGMENTS).
Takes a day to get the data back in line (never found out, who did the correction at night, could be RSCOLL00 ?).
Use above statement with "OWNER = " in WHERE for MCOD or connect as schema owner and use USER_SEGMENTS.
Use with
segment_name LIKE '<TABLE_NAME>%'
if you like to see the related indexes as well.
For partitioned objects, a join from dba_tables / dba_indexes to dba_tab_partitions/dba_ind_partitions to dba_segments
might be needed, esp. for hash partitioned tables, depending on how they have been created ( partition names SYS_xxxx).

Oracle Sql Query issue Running on Different DB Version
Hello All,
I have come into situation where we are pruning sql queries on different DB version of Oracle and have performance issue. Let me tell you in brief and i really appreciate for your prompt response as its very imperative stuff.
I have a query which is running on a DB of version 7.3.4 and it takes around 30 mins where as the same query when run on 8i it takes 15sec., its a huge difference. I have run the statistics to analyze on 7.3 and its comparatively very high. Question here is, the sql query trys to select data from same schema table and 2 tables from another DB using DB link and 2 other tables from another DB using DB link.So,how can we optimize this stuff and achieve this run as same time as 8i DB in 7.3. Hope i am clear about my question, Eagerly waiting for your replies.
Thanks in Advance.
Message was edited by:
Ram8Difficult to be sure without any more detailed information, but I suspect that O7 is in effect copying the remote tables to local temp space, then joining; 8i is factoring out a better query to send to the remote DBs, which does as much work as possible on the remote DB before shipping remaining rows back to local.
You should be able to use EXPLAIN PLAN to identify what SQL is being shipped to the remote DB, If you can't (and it's been quite a while since I tried DB links or O7) then get the remote DBs to yourself, and set SQL_TRACE on for the remote instances. Execute the query and then examine the remote trace files, And don't forget to turn off the tracing when you're done.
Of course it could just be that the CBO got better,,,
HTH - if not, post your query and plans for the local db, and the remote queries.

Hi Gurus,
This may be repeated question but I didn't find suitable answer and need your help.
There are number of webi reports which is based on olap connection directly on bex query. We are experiencing the slowness while opening the report and even opening for selection screen for prompts.
This is happening from past few days.
There is slight slowness in backend BI system as well.
All the BO servers are running fine.
BO Version: BO 4.0 sp6.6
Thanks & Regards,
Harsh WardhanSometime the cache got fill , restart the servers once and it should be as before.

Hi all,
I am runnig the query first time but it is taking very much time to run query . are there any parameter which we need to set from BIW when we run the query first time ?
when i try to dril down any char. or when i try to move any free characteristic to rows it is taking very much time.
please tell me the steps to improve the performance.
Regards,
Komik ShahHi,

General tips
Using aggregates and compression.
Using less and complex cell definitions if possible.
1. Avoid using too many nav. attr
2. Avoid RKF and CKF
3. Many chars in row.
By using T-codes ST03 or ST03N
Go to transaction ST03 > switch to expert mode > from left side menu > and there in system load history and distribution for a particual day > check query execution time.

/people/andreas.vogel/blog/2007/03/16/how-to-read-st03n-datasets-from-db
Try table rsddstats to get the statistics
Using cache memoery will decrease the loading time of the report.
Run reporting agent at night and sending results to email.This will ensure use of OLAP cache. So later report execution will retrieve the result faster from the OLAP cache.
4. Go to SE38 > Run the program SAP_INFOCUBE_DESIGNS
It will shown dimension Vs Fact tables Size in percent.If you mean speed of queries on a cube as performance metric of cube,measure query runtime.
3. To check the performance of the aggregates,see the columns valuation and usage in aggregates.
Open the Aggregates...and observe VALUATION and USAGE columns.
"---" sign is the valuation of the aggregate. You can say -3 is the valuation of the aggregate design and usage. ++ means that its compression is good and access is also more (in effect, performance is good). If you check its compression ratio, it must be good. -- means the compression ratio is not so good and access is also not so good (performance is not so good).The more is the positives...more is useful the aggregate and more it satisfies the number of queries. The greater the number of minus signs, the worse the evaluation of the aggregate. The larger the number of plus signs, the better the evaluation of the aggregate.
if "-----" then it means it just an overhead. Aggregate can potentially be deleted and "+++++" means Aggregate is potentially very useful.

Note 356732 - Performance Tuning for Queries with Aggregates
5. Run your query in RSRT and run the query in the debug mode. Select "Display Aggregates Found" and "Do not use cache" in the debug mode. This will tell you if it hit any aggregates while running. If it does not show any aggregates, you might want to redesign your aggregates for the query.
Also your query performance can depend upon criteria and since you have given selection only on one infoprovider...just check if you are selecting huge amount of data in the report
Check for the query read mode in RSRT.(whether its A,X or H)..advisable read mode is X.

Hi I have a sql query report that is taking very long to render.The query on sql developer comes back in less than a second.Any ideas on what could be wrong?
Hi
When posting code on the forum, put {noformat}{noformat} (with the curly brackets and the word code in lowercase) above and below your code like this...
{noformat}{noformat}
SELECT *
FROM emp
{noformat}{noformat}
It will then appear like this, preserving formatting...SELECT *
FROM emp
Next, how many rows are returned in total, it may be that you have SQL Developer set up to fetch only the first x number of rows?
Why have you put a CHOOSE hint in there?
Is it a classic report or an interactive report?
It looks like you're going over a database link, you really need to provide an explain plan (formatted as I have detailed above), a DRIVING_SITE hint may help you but it's impossible to know without seeing the plan...
Cheers

Can we change/Modify BI server generated Sql query and run to fetch data
Hi,
My client is saying that there is an option to modify bi server generated sql query to fetch data from source.
question:As a request is made in presentation services, A dynamic sql query is generated and fetches data from source. all this is loggedin Nqlquery log..well can we change/modify the sql query generated and run modified sql query to fetch data from source. ., if so how? if not why?
Thanks in advance

Hi All,
Please help. I am having a Prodution SQL 2008 RTM Cluster with two nodes-where node 1 works without any problem.However, if i failover to node 2-Agent xp's are disabled automatically. When i verify the SQL Services are node 2 are running fine.
Checked Agent.out file which did not give much info than below:
2012-09-09 08:00:12 - + [162] Internal request (from SetJobNextRunDate [reason: schedule will not run again]) to deactivate schedule 47
2012-09-15 06:50:30 - ? [131] SQLSERVERAGENT service stopping due to a stop request from a user, process, or the OS...
2012-09-15 06:50:41 - ? [098] SQLServerAgent terminated (normally)
I have verified that hardware and software of both nodes are identical. Still ,this issue persists always.
Please let me know the solution for this. it really pressurise on Production having one node active and other not active.
Harithasrisp_configure 'show advanced options', 1;
GO
RECONFIGURE;

sp_configure 'Agent XPs', 1;

Are the SQL Agent running under the same accounts?
