Whats the reason for taking more time

Hi,
I'm into production support, previously all loadings are fine from the past one month there is a problem in many infopackages taking more time for same no of records, normal wait time is 1 hr, but it is taking 2 to 3 hrs to complete.
Can any body tell the reasons for this and any resolutions will be a graet help for me.
Thanks in advance.
Siddhu

HI,
Try to analyse those cube for which loading is taking more time by RSRV Transaction especially see whether dimension table size is more than 20% of fact table size.
Another reason might be the Table Space Problem or also ask ur basis guys about the Redolog management , ask whether there is enough space while peak loading is going on....
Assign points if helps....

Why view have no stored data ? And what is the reason view take more time

Why view have no stored data ? And what is the reason view take more time to query ?
what happen if a view have stored data?

user12941450 wrote:
I want to know the reason that why querying view is slower then querying a normal table?..Untrue.
For example take a table with 2laks record and a view for that table.
If i make a query like( Select name,address from table) then it works fast then select(name,address)from view..Incorrectly interpreting the results.
A view is a SQL statement. Only difference is that the SQL statement is stored in the database's dictionary. Let's consider the following view:
create or replace view foo_view as select * from empWhen you use the view as follows:
select * from foo_viewOracle sees it as follows:
select * from (select * from emp)This is no slower, or no faster, than providing the following SQL to Oracle:
select * from empSo if you observe a difference in performance between using plain SQL versus using that same SQL via a view, there are other reasons for that difference in performance. The reason is NOT that views are slower.

1 sign out of apple account
2 close down passbook app
3 change year to 2013
4 reopen passbook and sign in at the button with your apple ID

Hi I am getting a light whitish bluish mark whenever i see any darker pictures. Whats the reason for it?

Actually, here's a clearer image. The middle stroke is with 20% drawing smoothness, and 100% pressure strength.
The top stroke is 100% both, and the bottom is 100% drawing smoothness with 20% pressure strength.
In all three instances, the dark watercolorish ring persists.

Currency translation taking more time at first time in the report

Hi All,
Here is an issue regarding the currency translation in the report. when we click on the currency translation from the contaxt menu on the report, its taking more time for the first time to get the selection options. But it is fast from the second time onwards. It will be not user friendly if its takes more time for the first time. Is there any way to fast up the processing time for the first time when i go for the "currency translation" option at report level for the first time.
let me know why it takes more time for the first time when we go for this option at report level.
Thanks,
Jack

Once again from the top.
This is undoubtedly not a database issue.
I doubt you can fix it in the database.
You can, however, spend a lot of hours asking questions and poking around if you are a consultant paid by the hour.
But as long as you are looking for something to do here are some that won't fix the problem but may be worth a few minutes of your time.
WHERE 1 = 1Are you kidding? Drop this nonsense. The Oracle optimizer is not brain dead. If it were my database I would also drop the parallel hint like a bad habit.
/*+ parallel(rp1, 8) */Again the Oracle optimizer is not brain dead. Ask for parallel threads that don't exist and the database will just queue your SQL and let it sit there until sufficient resources become available.

Log writer taking more time to write

Hi All,
we have oracle 10g(10.1.0) installed on rhel 5.3.. We are facing an issue regarding the logwriter..the logwriter is taking more time to write to the online redolog file...the trace file shows a warning message as " log writer time 840ms" ... Not sure what is the root cause of it..Please help me out in that regards..Thanks in advance...

imran khan wrote:
The archived log mode is disabled for the db..The online redolog files are not in FRA instead they are kept in diskgroups (multiplexed in two disk groups)..The controlfiles and datafiles are also stored in the same location as of online redolog files.The db is having the release as 10.2.0.4.0 and all the components are in 10.2.0.4.0 as well.
I also found that the ASM instance is having the release as 10.2.0.4.0(v$version view) but the compatibility attribute of the diskgroups is 10.1.0.0 . The compatible parameter in ASM instance shows 10.2.0.3.0 .
Do i need to change the compatibility of the diskgroups and the compatible parameter to 10.2.0.4.0 in ASM instance?
Not sure whether ASM compatibility makes any impact on delaying the lgwr to write to the online redolog files ?
Note : The online redolog files are stored in ASM diskgroups
please suggest...If your redo is in the same physical location as your datafiles, don't you think there might be some contention? (For my OLTP type of experience, undo is the most hit data file, too).
There could also be some more fundamental thing wrong, such as misconfigured I/O, and your redo just seems small. How often are they switching? Are you using hugefiles (as opposed to configuring them and unknowingly not using them)? Do you see any actual swapping to disk going on?
You likely have an OS I/O problem, but appear to only be looking at Oracle's view of it. What does the O/S say about it?
Are you sure you want to be running a production database without archive logging?

Query accessing SSAS cube is taking more time in power view report

Hi,
My SSAS server is having 16 Core's . I have created a power view in sharepoint site, which is accessing ssas cube.
The report is taking more time to show the result. I traced the DAX query using SQL Server profiler. When I ran this DAX query in SSAS server directly, then its taking less time but when the same query running from sharepoint server (power view) , it
is taking more time. Number of records in the fact table is 300M .
Also i tracked the %process time in performance monitor, mostly the line is below 20%. I think the CPU is not fully utilized..
Could you please help me to improve the performance of my report.
Regards,
Arun

Hi Arun,
According to your description, you create a PowerView report in SharePoint site connect to SSAS cube, the problem is that it take long time to show the result in the report, now you want to improve report performance, right?
In your scenario, you said that it takes more time to return the result in PowerView report than run the query directly in SSMS. For a report, its run time contain retrieval data time and render report time. So it takes more time to return the result in
PowerView report than run the query directly in SSMS. And there are 300M records in the fact table, the performance can be caused by large data. Here is a blog which describes tracks down Power View performance problems.

Oracle Drop command taking more time in AIX When compared to Windows

Hi
We are firing a normal Drop command on our database and the databse version is 10.2.0.4.The catabase is running on AIX v5.The command is taking more time than usual .
There are no waits on session.Let me try to put the scenario in more simple terms.I have a nested table NT_TEST with record count 0 and i am dropping the statement using "Drop table NT_TEST" in windows it is getting dropped say some 218 Milli seconds.
The same table when i am dropping it in AIX it is taking around 6 seconds.
There are no locks ,Flashback is off,Triggers are not involved.Drop is not waiting on any transaction to complete.
Could anybody help me out on this.

Quite possible. On most Unixes asynchronous I/O requires purchasing extra options, and most sites just purchase the default O/S. Or asynchronous I/O is not enabled by default or the database is located on an ufs file system.
You provided no info at all on your AIX configuration. AIX does have asynchronous I/O, it is not always enabled, and the number of slaves is usually way too low.
As root, run smit aio and report the results.
At his point your unfavorable comparison of Windows and AIX is quite unfair. Unix doesn't run out of the box.
You know that famous joke 'If operating systems were airplanes'?
In that joke, the Unix airplane is assembled on the spot, but the Windows airplane is three months late.

What is the reason for query take more time to execute

Hi,
What is the reason for the query take more time inside procedure.
but if i execute that query alone then it excute within a minutes.
query includes update and insert.

I have a insert and update query when I execute
without Procedure then that query execute faster but
If I execute inside procedure then It takes 2 hours
to execute.Put you watch 2 hours back and the problem will disappear.
do you understand what I want to say?I understood what you wanted to say and I understood you didn't understood what I said.
What does the procedure, what does the query, how can you say the query does the same as the procedure that takes longer. You didn't say anything useful to have an idea of what you're talking about.
Everyone knows what means that something is slower than something else, but it means nothing if you don't say what you're talking about.
To begin with something take a look at this
When your query takes too long ...
especially the part regarding the trace.

What could be the reason for Crawl process to take long time or get in to a hung state.

Hi All,
What could be the reason for Crawl process to take long time or get in to a hung state? Is it something also related to the DB Server resources crunch? Does this lead to Index file corruption?
What should be the process to be followed when index file is corrupted? How do we come to know about that?
Thanks in Advance.

"The crawl time depends on what you are crawling -- the number of items, the size of the items, the location of the items. If you have a lot of content that needs to be crawled, it will take much time".

Any particular reason why you have a non-default value for a hidden parameter, optimizercost_based_transformation ?
On my 10.2.0.1 database, its default value is "linear". What happens when you reset the value of the hidden parameter to default?
