Consistent gets are reduced but elapsed time is increased.
Hi All,
While tuning a application my consistent gets are reduced by 50% but the query is still taking the same time.
In a Warehouse env data is coming from With clause that is having some 40000 rows .Then these 40K rows are joined to a table that is having 2 Billion records having indexes on primary key and date column(bitmap)indexes .
This forum is for issues with the SQL Developer tool. You'd get more response in the General Database forum.
Have fun,
K.

It is using Hash Joining method.Try forcing a hash join, if possible:

Hi ,
I am tuning a query in DWH env using a WITH clause .Doing that my consistent gets are reduced by 50% but the elapsed time in increased.
In that one 40000 rows are coming from WITH clause and joined with a table having 250000000 rows joined through Hash join.
can anybody help me out in this issue.
Thanx

Normally time goes, down when system resources do - but not always as you are seeing :(. Last time I saw something like this the reads had gone down but the CPU usage had gone up. You can get CPU usage from V$SQL.
Can you post the query, the execution plan, and statistics - both before and after the tuning? -
How to get Sum for my Elapse Time string for my group
Hi,
How can I get the sum of an elapse time string in my group footer 2 and group footer 1 from the report screenshot attached.
I have a report that display TimeIn and TimeOut of an employee.
For the total time I have created a formula that will take my time in seconds and displaying it in hrs, minutes and seconds.
How can I get the sum of all the total time per day and display this in my group footer 2.
As well I will need to add the grand total to group footer 1 for the total of days.
The formula I have for the total time is as follow:
WhileReadingRecords;
NumberVar TotalSec := {TimeLogs.TotalTime};
NumberVar Hours := Truncate (Remainder ( TotalSec , 86400) / 3600) ;
NumberVar Minutes := Truncate (Remainder ( TotalSec , 3600) / 60) ;
NumberVar Seconds := Remainder (TotalSec , 60) ;
Totext ( Hours , '00' ) + ':' +
Totext ( Minutes , '00' ) + ':' +
Totext ( Seconds , '00' )
This is a seperate question below but related as well to this report.
Another question I have is how can I round up for example 03:30:58 to 03:31:00
And also how can I round down for example 03:26:10 to 03:26:00
Any help would be appreciated.
Thank you,
JoeHi Jamie,
Well I ran into an issue with this. My Daily Total, there is no issue, it is displaying the proper time. But when I add a summary to my Group Footer 1, it doesn't add up properly.
If I select only 1, 2, or 3 days my Date Range Total is adding fine but when selecting 5 days for example, as you can see from the picture below, for an unknowned reason the total of hrs is wrong.
Do you know why this is happening.
Than you for your help.
Joe

I was also looking from a DBA point of view, say increasing the DB_CACHE_SIZE from 5GB to 8GB as the machine has almost 32GB memory out of which 13GB is free memory. Because the timed event is "db file sequential read" which takes 95% of Total Call time.

When I use Firefox I get random crashes but if I try to Download it will crash every time. I get no warning just this program has stopped working and is shutting down then I will get to you wish to restore your session when I restart Firefox or I get there is already a version of Firefox running even when it has been shut down and I have to restart my computer to get Firefox back up. I think this might be a conflict with adobe flash or one of these programs but I can not find any info on this problem.
This article should help - [[Firefox crashes when trying to download a file]]

How can I resolve this issue so that I can clearly see my statement. I asked the question on Yahoo Answers and the concensus was switch to Google Chrome? Surely that's not the answer?
Hello,
Please try restarting Firefox in safe mode and see if the problem goes out.
If it works fine in safe mode then one of your Extension may be causing the problem.

I would like to get a better understanding of what exactly this statistic means. Oracle documentation states:
Consistent Gets is the number of times a consistent read was requested for a block.
Is the data included in Consistent Gets coming from a Rollback Segment of from a DB Cache?
In the datawarehousing environment with very heavy reporting and ETL running at the same time, when Consistent Gets statistic is 5 times higher than Physical Reads, is that a reason for concern?In the datawarehousing environment with very heavy reporting and ETL running at the same time, when Consistent Gets statistic is 5 times higher than Physical Reads, is that a reason for concern? <<It doesn't sound relevant -- if your reporting is using parallel query then it is bypassing the buffer cache, hence a logical i/o against the table being parallel-scanned is going to be a physical i/o also. So, much would depend on how much use you are making of parallel query.
The parallel query LIO/PIO effect is easy to demonstrate by querying a chunk of data twice with a noparallel hint and twice with a parallel hint, and having autotrace turned on. you'll see the PIO's drop down on the second execution of the noparallel query, but on the parallel query they'll remain pretty much the same on the second execution. -
hello guys ,
I need ur help ..
I have a really simple task to do : i need to push a button , and after 15 second , a LED should turn on
I've been looking in the forum for such questions , but all of them are advanced or using another version which i can't open !
However i've seen that almost everybody are using the elapsed time block , So if you can please tell me how should i connect this block to my circuit .

The simplest way is to use the Wait function, wire 15000 (milliseconds) to it. After it is completed, set the LED value to true. To ensure that the LED happens after the wait function, use a sequence structure.
There are better ways to create delays but this will be sufficient for what your asking.
i wouldnt do that...that will keep anything within the loop from responding to user interface within that time
CLD 7.b.3. Avoid using any of the Wait functions to time a software operation
better to use elapsed time.vi, tick count, time stamp....
You are correct in that it prevents other items from responding and I did say that it was a basic solution. I normally use timestamps for items such as this so the rest of my code keeps running (I don't usually need very precise timing so errors introduced in when the timestamps are checked don't usually matter to me). -

How to get elapsed time of the query in form 6i
hi
I used to use " set timing on " in sql to get the elapsed time
set timing on
elapsed time :XX:XX:XX ,
but i dont know how to get it in fom
its really imporant to measure the time elapsed for me cuz i am student an need to get the time
thanx alotregarding to point 1 : u know there are three modes for system ; query, enter_qeury,and normal. when the system is not noraml so it is either query or enter_query , and both are query processing ( as i think) so it the elapsed time . it also by using timer stpos when system finish query ( normal)
why you dont prefer timers ..... ( it important please to explain )
thank you very much Navnit Punj

I want to access my Icloud account through my office computer but every time I get a message saying ''iCloud encountered an error while trying to connect to the server''
My recommendation is to download Apple’s Safari version 5.1.7 for Windows to access iCloud.com. It consistently works for me!!!! To make things easier with Safari, I made iCloud.com its Homepage. I’m using it to access iCloud.com from all of my PCs.
On my Windows 7 systems it appears that some add-ons are causing problems when you try to access iCloud.com with the 32-bit version of IE9, but the 64-bit version seems to work fine, more than likely because there are few add-ons that are 64-bit and the 64-bit version of IE9 can't be the default browser in Windows 7.
