Sql takes different times to run on different teminals

My sql query runs fine on my system but takes too long time to execute on
another terminal which is at client location.
Can anybody please tell me what would be the possible causes or where should
I look into to resolve this problem?
Thanking you

My sql query runs fine on my system but takes too long time to execute onanother terminal which is at client location.
Run fast on server, and slow on client machine, right ?
See if there bottleneck network problem.

The 0co_om_opa_6 ip in the process chains takes long time to run

Hi experts,
The 0co_om_opa_6 ip in the process chains takes long time to run around 5 hours in production
I have checked the note 382329,
-> where the indexes 1 and 4 are active
-> index 4 was not "Index does not exist in database system ORACLE"- i have assgined to " Indexes on all database systems and ran the delta load in development system, but guess there are not much data in dev it took 2-1/2 hrs to run as it was taking earlier. so didnt find much differnce in performance.
As per the note Note 549552 - CO line item extractors: performance, i have checked in the table BWOM_SETTINGS these are the settings that are there in the ECC system.
-> OLTPSOURCE - is blank
   PARAM_NAME - OBJSELSIZE
   PARAM_VALUE- is blank
-> OLTPSOURCE - is blank
   PARAM_NAME - NOTSSELECT
   PARAM_VALUE- is blank
-> OLTPSOURCE- 0CO_OM_OPA_6
   PARAM_NAME - NOBLOCKING
   PARAM_VALUE- is blank.
Could you please check if any other settings needs to be done .
Also for the IP there is selction criteris for FISCALYEAR/PERIOD from 2004-2099, also an inti is done for the same period as a result it becoming difficult for me to load for a single year.
Please suggest.

The problem was the index 4 was not active in the database level..it was recommended by the SAP team to activate it in se14..however while doing so we face few issues se14 is a very sensitive transaction should be handled carefully ... it should be activate not created.
The OBJSELSIZE in the table BWOM_SETTINGS has to be Marked 'X' to improve the quality as well as the indexe 4 should be activate at the abap level i.e in the table COEP -> INDEXES-> INDEX 4 -> Select the u201Cindex on all database systemu201D in place of u201CNo database indexu201D, once it is activated in the table abap level you can activate the same indexes in the database level.
Be very carefull while you execute it in se14 best is to use db02 to do the same , basis tend to make less mistake there.
Thanks Hope this helps ..

Auto message restart job take long time to run

Dear all,

HI,
If you are using oracle database you may need to run table statistics report (RSOANARA) to update the index. The system admin should be able to this.

You can try this and see if it helps.
Issue is you are getting millions of rows in return and then you're doing where rownum< .... So the
query has to run in full in any case.
Try to use first rows hint if you care about getting immediate results.
Try performing fts
convert your rownum < :xyz into an actual column filter from the refined rows.....

Process Chain takes alonf time to run

Hello All,
We have a process chain which loads data for texts, attributes etc.
On certain days the process chain will run extremely fast and maybe take a couple of hours, other days the same process chain may take 24 hours to run. It appears to get stuck when extracting the data from our source system.
Is there any reason for these strange performance issues and does any body else have the same problem? Is there anything that can be done about it?
Thanks,
Nick.

Hi Nick,
This error normally occurs whenever BW encounters error and is not able to classify them. There could be multiple reasons for the same
Whenever we are loading the Master Data for the first time, it creates SIDs. If system is unable to create SIDs for the records in the Data packet, we can get this error message.
If the Indexes of the cube are not deleted, then it may happen that the system may give the caller 70 error.
Whenever we are trying to load the Transactional data which has master data as one of the Characteristics and the value does not exist in Master Data table we get this error. System can have difficultly in creating SIDs for the Master Data and also load the transactional data.
If ODS activation is taking place and at the same time there is another ODS activation running parallel then in that case it may happen that the system may classify the error as caller 70. As there were no processes free for that ODS Activation.
It also occurs whenever there is a Read/Write occurring in the Active Data Table of ODS. For example if activation is happening for an ODS and at the same time the data loading is also taking place to the same ODS, then system may classify the error as caller 70.
It is a system error which can be seen under the Status tab in the Job Over View.

NAC Agent takes long time to run

Cisco NAC agent takes long time to popup or run on Windows 7 machine.
The client machine is windows 7, running nac agent 4.9.0.42, against ISE 1.1.1
Any ideas how to reduce NAC Agent timing?

Hi Tariq,
I'm facing the same issue with ISE 1.1.1 (268) with Agent 4.9.0.47 for Windows XP clients. I have already configured "yes" to disabled the l3 swiss delay and reduced the httpa discovery timer from 30 to 05 sec but still clients get aprox 2.30 minutes to popup and finished the posture discovery.
Can you please advise if this is the minimum time or what is the minimum time and what are the parameters to set to a minimum time to complete agent popup and posture discovery..?
Is there any option that we can run this on backgroup..?
thanks in advance..

Oracle9i reports take longer time while running in web

Hi,
I have developed few reports in Oracle9i and I am trying to run the reports in web. Running a report through report builder takes lesser time compare to running the same report in web using web.show_document. This also depends on the file size. If my report file size(.jsp file) is less than 100KB then it takes 1 minute to show the parameter form and another 1 minute to show the report output. If my file size is around 190KB then the system takes atleast 15 minutes to show the parameter form. Another 10 to 15 minutes to show the report output. I don't understand why the system takes long time to show the parameter form.
I have a similar problem while opening the file in reports builder also. If my file size is more than 150KB then it takes more than 15 minutes to open the file.
Could anyone please help me on this.
Thanks, Radha

This problem exists only with .jsp reports. I saved the reports in .rdf format and they run faster on web now. Opening a .jsp report takes longer time(file with 600KB takes atleast 2 hours) but the same report in .rdf format takes few seconds to get opened in reports builder.

Using a different TIME range that is different from the default TIME dim

Hi all - this is my first post - so please be gentle!
I am busy writing an EVDRE report on an application for which I need to use a different time range than what is currently the overall time dimension for all our other applications.
Currently the overall time dimension is set for MAR to FEB (Financial year). I now need to do a report for - OCT to SEP reflecting the YTD values?
The report also calls for having variable A compared against variable B over the extent of this period (OCT to SEP -> YTD). So in essence I will not be displaying any PERIODIC values but rather just the YTD values.
How can I do this without having to resort to a manual entry of each month's TIME dimension details and still ensure the report dynamically changes when I do an EXPAND?
I am using BPC 5.1 SP3 on Microsoft Office 2003.
Kind regards
Pieter

Well, without seeing the report and the setup, my suggestion is to leverage the EVTIM function. If your columns are static, but the user selects a period for the report, you should be able to set-up the function to build the 2 sets of 3 months. The EVTIM function simply references another time value, and adds up or down at a specific level as a member for use in the column (or that is where I would use it).
Does that make sense?

The problem is that this code takes about 24hrs to run which is not accepted.
Kindly suggest us some other technique to implement the same logic.
For your reference, the KPM_HR_ABSENT_RECORD table has about 3,75,000 records in it.
Also we have created some indexes on certain column as recommended by explain plans.
Thanks in advance

Take longer time to run sql worksheet

Hi,
I using sql developer for running a script in sql worksheet, it take an endless time to complete running the command, and the command is just a simple query (e.g. begin xxxx end;)
This problem doesn't happen before in my pc. I had try to reinstall the software but still the same. Any one can help me?
I using oracle sql developer v1.5.3
Window 2K SP 4, 512 RAM Intel Pentium 1.8 GHz
Java SE development: jdk 1.6.0_03
Thanks

Sure it's as simple as you think? How about a SELECT * FROM DUAL ?
What kind of database is this?
Can you see in the Enterprise Manager (or similar) if the database is very busy or something?
Can you verify with another tool if it's related to sqldev or not?

One query taking different time to execute on different environments

I am working on Oracle 10g. We have setup of two different environments - Development and Alpha.
I have written a query which gets some records from a table. This table contains around 1,000,000 records on both the environments.
This query takes 5 seconds to execute on Development environment to get 200 records but the same query takes around 50 seconds to execute on Alpha environment and to retrieve same number of records.
Data and indexes on the table is same on both environments. There are no joins in the query.
Please let me know what are the all possible reasons for this?

Function returning query takes more time to run in Apex4.0

Hi All,
I created a report using function returning query. The function returns query based the parameters which returns dynamic columns. When I run the query in sql developer the query generates and returns the result in 3mins. But in apex it takes maximum of 35mins to return.
The query will return around 10000 rows.
Is it a performance issue in the query or in Apex?can anyone please help
Regards
Raj

Hi Roel,
Thanks much for your suggestion. I run in TOAD and got the result as
Row 1 of 500 fetched so far in 3.31 minutes which means it queried for 500 records alone ? is that not the actual time taken to run the fulll query?That reflects the time to return the first 500 records...
Please suggest.With all the best will in the world, if I was your user and I had to wait 3 minutes for the page to refresh, I'd steadily lose the will to live!
As this is primarily an SQL tuning question, have a look at this message in the FAQ thread in the {forum:id=75} forum:
{message:id=9360003}
That should give you some pointers on the right approach.

Threaded program takes more time than running serially!

Hello All
Ive converted my program into a threaded application so as to improve speed. However i found that after converting the execution time is more than it was when the program was non threaded. Im not having any synchronised methods. Any idea what could be the reason ?
Thanx in advance.

First, if you are doing I/O, then maybe that's what's taking the time and not the threads. One question that hasn't been asked about your problem:
How much is the time difference? If it takes like 10 seconds to run the one and 10 minutes to run the threaded version, then that's a big difference. But if it is like 10 seconds vs 11 seconds, I think you should reconsider if it matters so much.
One analogy that comes to mind about multiple threads vs. sequential code is this:
With sequentially run code, all the code segments are lined up in order and they all go thru the door one after the other. As one goes thru they all move up closer, thus they know who's going first.
With multi-threaded code, all the code segments sorta pile up around the door in a big crowd. Some push go thru one at a time while others let them (priority), while other times 2 go for the door at the same time and there might be a few moments of "oh, after you", "no, after you", "oh no, I insist, after you" before one goes thru. So that could introduce some delay.

Sql takes different times to run on different teminals
