Optimizer - Plan Change - No Stats Changed

Hello,
Last week we had a surprise when a well performing query in production started to become worse.
Query that used to run in seconds started taking 3000-4000 secs. It never completed, and the application timed out.
The stats on the table has been locked for more than 15 months now. This is a transactional table.
DB Version : 10.2.0.4
To replicate the issue, we copied over the data and stats from production to development box. We couldn't replicate it in there and hence the question.
Here is the query..
SELECT QREF

SP.REQUEST_ID IN (SELECT W.REQUEST_ID
                           FROM WEBCFL_SPEED_PRICING W
                          WHERE W.QREF IN
select 'Q14850501 N1' from dual
union all
select 'Q14850501 N3' from dual
   AND PAIR_ID IN (SELECT PAIR_ID

------------------------------------------------------------------------------------------------------------------The second half of the plan is same in Prod and Dev. It is the first half of the plan that is causing the problem.
In the good plan in Dev, I don't see a MERGE CARTESIAN JOIN in the first part. But, in the plan in production, I do see this.
One bit of detail is: The stats on this table is locked for more than 15 months now. Not sure why, but someone did it to solve some issue previously.
I have compared the structure in production and dev. Stats for the table is same in production and dev.
I haven't checked the optimizer env parameters and the system stats between the systems.
Still waiting for the information.
Any pointers ?
Rgds,
Gokul
Edited by: Gokul Gopal on Dec 10, 2012 6:24 PM

Hi,
1) the stats didn't change, but the query probably changes all the time (that's the whole point of using dynamic SQL). The costs of the two plans are similar, so it wouldn't be surprising at all if a slight change in the query would result in a significant change in the plan
2) it's hard to compare entire plans, but one of noticeable differences is the fact that one query uses 1 cartesian merge join, while the other is using 2. You can try disabling cartesian merge joins with a hint or on the session level
3) it's more difficult for the optimizer to estimate cardinality of
select * from tab where col in ('value1', 'value2', ...)than
select * from tabl where col in
(select 'value1' from dual
union all
select 'value2' from dual
union all
);so if possible, you should consider rewriting this query in a way that is less confusing to the optimizer
4) I would be worried about not being able to replicate the issue on a test box -- it means that you can't use your test box to test production performance issues. The difference in behavior suggests that there must be some difference in optimizer settings or table stats (or both). Did you try importing the stats from prod? You can also try dumping parameters to text files and running text comparison to isolate parameters that differ
5) in a comment to your original post you mention that the issue was resolved -- but it doesn't sound like a sustainable solution, rather, looks like a temporary workaround
Best regards,
Nikolay

How can I initialize all TabNavigator Tabs upon a state change?

Here's the basic goal. I want to provide two views to the
user that display the same panels. I configured each view as a
separate state but I am having trouble initializing each of the tab
views since they are only created by Flex when the user first
selects it. I need them all created when the user changes to that
state so that I can insert my view objects. Does that make sense?
Ok, how about an example program. I define three view objects
in ActionScript which will be used in two different states. I use
AddChild to put them in the proper layout location. The problem is
with the Tab state. The AddChild operation only works for the first
tab because it is visible. The other two tabs don't get setup
properly. Can anyone help me resolve this?

Ok, here is an even simpler scenario. I take each view from
the default state and put them in the new tab view when the state
changes. If you compile and run this example, the only view that
makes it into the tabview is the one that was active when the state
changed. Why is that?

How can I change the state of a runtime menu item programatically?

Using LabView 6.1, I would like to change the state of the runtime menu item "Operate/Print at completion".
The goal here is to print the VI front panel according to the operator choice (OK ->print, Cancel ->don't print)
In a first release, I put a Stop function at the dialog output (activated by the cancel button) but this function stop the complete application and my idea where to stop only the VI in which the dialog is running.
In a second release, I've tried to use the "Application
control/Menu" but I receive every time an error:
Error 88 occured at Cannot modify application menu item in the printtest.vi.
Possible reasons: LabView, Runtime menu error...
Any suggestion is appreciated.
Re
gards,
phidu

Instead of using the print at completion option, print the VI programatically if the user selects to print...open a reference to the VI you want to print and use an invoke node to print vi to printer.
Alternatively create another VI with a layout optimized for printout, set it to print at completion and run and load the data into that VI if and only if the user OKs the print...

How can I change a State name in iphoto map?

A few months ago, changing a location of a group of photos, I really changed a state name.
The image shows the name State "Casa David i Mireia" where should say "Catalunya" that is the real name.
How can I change that name. I have opened a case in Apple Support, but the solution to reinstal the app have not worked for me.
Thank you for your help
Jordi

Thanks for your help!
The problem is that I think that I changed the "default" name for the state where the photos were taken. I have 50 differents locations, that are all correct, and photo per photo, I can modify the original location, but only at "local" level.
How can I change the name displayed in State section as "Casa David i Mireia" for "Catalunya" that is the real name for the State where the photos where taken?
I don't if this post is comprehensive. I'm not sure.
Thanks for your time!

Is it possible to change application state from a component?

I was wondering if it is possible to change application state from within a custom component and if so, what would the syntax be if I had an application named "zzz" and I wanted to change the app state from "state1" to "state2" from my component?
Thanks!

Hi,
you always have a static class Application.
Application.application will be the root component. After that you can change it state.
Application.application.currentState = "state2";
But it's not the best way to change states. It's better to dispatch events from components and change states in listeners.

Rfkill state changes no wifi

While trying to resolve other laptop (HP dv9653cl) issues, I broke the ZIF connector that attaches my hardware wireless switch to the mainboard. While the wifi card itself still works, I can't change the rfkill switch state. On boot it is a 1 and I have connectivity, but after a short amount of time (varying from about 30 seconds to 5 minutes) it changes to a 2 and my wifi card no longer detects networks.
I can't change the state manually. I tried adding "rfkill=1" to the end of my boot options in /boot/grub/menu.lst" but nothing changes. I've also tried to reload my wifi card and relevant drivers manually (ifconfig wlan0 down/up & modprobe [-r iwlagn), but that seems to have no positive effect.
Warranty has expired so sending it into HP is not an option, and for now I can't afford the replacement part. I was wondering, is there was another way to ensure that the rfkill state stays at 1 (or if infact the way I am doing it is incorrect), or if there was some software that would allow me to bypass the kill switch all together similar to HP's propiretary software (which DOESN"T run under wine)?

What is the best practice for changing view states?

I have a component with two Pie Charts that display
percentages at two specific dates (think start and end values).
But, I have three views: Start Value only, End Value only, or show
Both. I am using a ToggleButtonBar to control the display. What is
the best practice for changing this kind of view state? Right now
(since this code was inherited), the view states are changed in an
ActionScript function which sets the visible and includeInLayout
properties on each Pie Chart based on the selectedIndex of the
ToggleButtonBar, but, this just doesn't seem like the best way to
do this - not very dynamic. I'd like to be able to change the state
based on the name of the selectedItem, in case the order of the
ToggleButtons changes, and since I am storing the name of the
selectedItem for future reference.
Would using States be better? If so, what would be the best
way to implement this?
Thanks.

I would stick with non-states, as I have always heard that
states are more for smaller components that need to change under
certain conditions, like a login screen that changes if the user
needs to register.
That said, if the UI of what you are dealing with is not
overly complex, and if it will not become overly complex, maybe
states is the way to go.
Looking at your code, I don't think you'll save much in terms
of lines of code.

Change a state in main.mxml from a script in another mxml

Hi,
i'm having some trouble with my application, let's say i have the main application file called MAIN.MXML
in wich i have set different States, and have different forms.
now i have a form called loginForm which contains the textInput item for Login and Password, i also have a link Need to Register
which onClick will change the state to show in the same panel a different form registerForm (with the relevant textInput items)
now the MAIN.MXML includes a custom component called <comp: NetworkManager /> which includes all the logic scripts and MXML
tags to create and manage an HTTPService request to a PHP Server.
when the user click on the Login button, this will call a function included in the main.as script (imported in MAIN.MXML) which
will call a function in the script within NetworkManager.MXML passing all the form data.
in NetworkManager.MXML the script will create an XML message, will send to the PHP Server and wait the response... if this comes
true the user is authenticated, otherwise is not.
so far so good, i get the message sent, the correct response back. Now i want to hide the form in MAIN.MXML and put something like
Welcome firstName lastName!! instead. But i don't know how to do it. If i try to access the states in MAIN.MXML from the NetworkManager.MXML
i'll get all sort of errors which i don't have it here with me.
I know this sounds like a newbie question, and it really is ... any taker?
your help is much appreciated.
thanks

who is the caller of loginForm then? i've tried with Application.application.loginForm but i do get the same error though.
loginForm is contained in a Canvas item, is it the caller? or who else?

I am trying to do a blank composition widget, but it keeps ignoring my state changes for the trigger. How can I have my state changes still work for things placed in the trigger?

So below is what I have so far. The menu is working perfectly, thanks to a few Youtube tutorials. And everything is linked correctly. But the only thing is that the "WORK" button doesn't respond to the state change that is set up for it. I tried applying the state change before I placed it in the trigger area, and after. Neither seems to make it work.
The goal state change is basically that the text "WORK" will turn white, and the white space within the teal stroke will also turn teal. So, the colors will reverse. I have a link next to it, "ABOUT" that is currently successfully doing it. I guess if it's not possible then I will have to figure out another design..but I'd like to see if there is a way to do it!

I believe you are trying to get a color state for composition when its active ? please publish the site and provide the url to have a look.
Thanks,
Sanjit

How do I change the states of the "Submit" button in adobe muse?

How do I change the states of the "Submit" button in adobe muse? Currently I can only change the color, text and stroke of the button, but I cannot customize it as I have the other buttons in the tool.

I want to replace the button with an image, however it does not permit me to paste an image into the button, nor does it allow me to delete the box that is currently there. The best I can do is paste the image into the text box that is provided.

Change the background color for HToggleButton as State changed

Hi , I want to change the background color of HToggleButton or HGraphicButton as its state changed as normal to focus and then focus to normal and same with actioned state .It is possible to change the image with different states but how can I do the same thing to change background color .I'll appreciate any help regarding this with thanks in adv.

Satya,
i_x denotes first column and not characctersitic 1.
Also I am not sure if the check is to be for IS_SUM.
Use Get_Cell_info class instance and then use the data returned by the same for checking IS_SUM and then change the cellstyle.
Another thing to look out for is , the required change might be needed on DATA_CELL and notcharacteristic_cell.

Can I change the state of an object by highlighting over text?

That question probably doesn't make sense, but I didn't know how to word it with just a few words.
I'm working on a site where I have a 'button' that has text in it. When someone hovers over the button, it changes colors (it's basically showing the user that the site is responding). When I put text inside the button, it causes the button to not change colors when I hover over it.
I know that it's happening because the text is covering up the area that is supposed to respond to the user's mouse.
So, I'm wondering if there is a way of either making the text and the 'button' all one object, or if it's possible to make the text 'invisible' to the mouse. What I mean by 'invisible' is that the computer wont acknowledge the text which will make the button responsive to the user's mouse.
I am able to do this through photoshop but I was just wondering if it's possible to do this in only muse.

Hi
You can define states for the background layer such as rectangle and then insert text frame which will change the state on hover of mouse, but if the text frame covers the background then it wont active the state.
The purpose that you are trying to achieve such as invisible text to mouse is not possible with native menu features , but yes as you have mentioned you can use an image for this , write up the text and use the image.
The state button has same feature with rectangle in background and text within that.
Thanks,
Sanjit
