Slow page rendering due to a LOV!

I was trying to figure out what the cause of my slow page rendering was and looking at the debug results I figured for one of my page items which is a LOV I get:
0.18800 13.98400 ...Session State: Save "P2_CATEGORY" - saving same value: "4"consistantly taking around 14 seconds.
I have even simplified the LOV to type static, and it only has 6 values. There is only one computation for this item which is static assignment only when the value of item is null.
I'm wondering if it's the item being saved in session really which is taking all this time or something else could be causing it to run slow. I mean, can the debug results be misleading me?
I'm using Apex 4.1 and Oracle 11g. I have 40 Shared_servers set.
I would appreciate any hints.

Hi,
set partialSubmit=true on the button

Dreamweaver CS6 and CC both very slow page rendering under Mavericks

Dreamweaver CS6 and CC both very slow page rendering under Mavericks compared to 10.8.5
Any ideas?

One other thing I am seeing:
When I open any document (html, javascript) inside DWCC now, then close it without any changes, DW asks if I want to save changes.
I just tested this under 10.8.5 and there is no lag there, nor are documents mysteriously modified when opened.
Note: I have tested this both with and without other Apps or extensions running in Mavericks and 10.8.5

ADF 11g - Very slow page rendering

Hi,
In our application we have a page with many panel boxes which are by default visible='false'. On the selection of a row in the table the particular panel box would be rendered and shown on the page.
The problem we are facing is with a very simple transaction, the user selects a particular type and there is a simple button which submits the records selected to data base and shows a popup. This process is taking very long. While debugging we have observed that the submission is happening fast but the displaying of the pop up and the page is time taking.
When we removed all the code from the page and just left the code for the above transaction and did the testing there was no delay. The complete flow went very fast.
We are using Fire fox 3 as our default browser.
Can any one please help us in improving the performance of the page?
Thanks,
Manasa.

Hi,
We have solved the performance issue by tuning all the VOs being used in the Page. One more factor which increased the performance was clearing the multiple iterators that got created in the pageDef during the course of development.
Hope this helps you.
Thanks,
Manasa.

Very slow page rendering compared to ie and windows...

I recently setup a 64 bit athlon pc for a friend and have noticed that web pages load extremely fast using either firefox or ie on the windows machine compared to my power mac and power book running either safari or firefox. I've tried a lot of the suggestions to get safari to load pages faster but nothing seems to work. Am I alone here with this issue or do others notice this as well? I'm currently on a 6 mbit cable connection.
Any suggestions?

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] (don't forget to select ''Disable all add-ons'' when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and themes and [https://support.mozilla.com/en-US/kb/Troubleshooting+plugins this one] for plugins.
If you need support for one of your add-ons, you'll have to contact its author.
If the problem does not disappear when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.

Partial page rendering making the transaction very slow

Hello,
I have partial page rendering enabled to 3 radio buttons in a page. Whenever i click a radio button, its taking around 15 to 20 seconds to finish the transaction and select the radio button. Not sure how to make it react faster. Any advice?
Thank You
--KK

Hi KK ,
Is it slow every time you click on radio button and its happening intermittently ?

Why is connection speed and page rendering so much slower in FF 3.6.13?

After installation of the 3.6.13 upgrade, website connection and page rendering speed became significantly slower than in all previous versions. I searched the knowledge base and Forum and found this post:
http://support.mozilla.com/en-US/questions/668695#answer-108852
After changing settings as described in the post, speed was easily more than doubled.
I'm wondering if anyone else has experienced the slowdown in connection and rendering speed with 3.6.13. And also why, if the settings worked so well for me, they aren;t standard in FF?

ADF Faces : simultaneous partial page rendering

hi
I'm wondering what I can expect from "simultaneous partial page rendering".
I would like to have some af:selectOneChoice components on a page, with next to them some related information about the selected value.
This example application, created using JDeveloper 10.1.3.3.0, does this using partial page rendering (check README.txt):
http://verveja.footsteps.be/~verveja/files/oracle/SimultaneousPPRApp-v0.01.zip
It as a pprPage.jspx with these components ...
          <af:panelPage title="pprPage">
            <af:panelHorizontal>
              <af:commandButton text="some button"/>
              <af:objectSpacer width="10" height="10"/>
              <af:outputText value="requestCounter.value = #{requestCounter.value}"/>
            </af:panelHorizontal>
            <af:panelHorizontal>

                                  binding="#{backing_PPRPage.selectOneChoiceA}"
                                  valueChangeListener="#{backing_PPRPage.onChangeSelectOneChoiceA}">
                <af:selectItem label="null value label"
                               value="#{null}"/>
                <af:selectItem label="first choice label"
                               value="first-choice-value"/>
                <af:selectItem label="second choice label"
                               value="second-choice-value"/>
                <af:selectItem label="third choice label"
                               value="third-choice-value"/>
              </af:selectOneChoice>

            </af:panelHorizontal>
            <af:panelHorizontal>
              <af:selectOneChoice label="selectOneChoice B"
                                  id="selectOneChoiceB" autoSubmit="true"
                                  binding="#{backing_PPRPage.selectOneChoiceB}"
                                  valueChangeListener="#{backing_PPRPage.onChangeSelectOneChoiceB}">

                               value="fifth-choice-value"/>
                <af:selectItem label="sixth choice label"
                               value="sixth-choice-value"/>
              </af:selectOneChoice>
              <af:objectSpacer width="10" height="10"/>
              <af:outputText value="#{backing_PPRPage.selectOneChoiceBRelatedValue}"
                             partialTriggers="selectOneChoiceB"/>
            </af:panelHorizontal>
            <af:outputText value="userAgentHelper.info = #{userAgentHelper.info}"/>
          </af:panelPage>... and has a backing bean like this ...
public class PPRPage
     public String getSelectOneChoiceBRelatedValue()
          return "some " + fSelectOneChoiceB.getValue() + " related value"
               + ", requestCounter.value = " + ELHelper.get("#{requestCounter.value}");
     public String getSelectOneChoiceARelatedValue()
          return "some " + fSelectOneChoiceA.getValue() + " related value"
               + ", requestCounter.value = " + ELHelper.get("#{requestCounter.value}");
     public void onChangeSelectOneChoiceA(ValueChangeEvent pValueChangeEvent)
          // simulating a slow operation/response
          try
               Thread.sleep(2000);
          catch (InterruptedException ex)
               ; // ignore;
     public void onChangeSelectOneChoiceB(ValueChangeEvent pValueChangeEvent)
          // nothing here to slow things down
}It is important to note that changing the value for the "selectOneChoice A" dropbox has some time consuming operation to perform (possibly calculating/querying the related information to show next to it).
Using IE 6 ("userAgentHelper.info = ... MSIE 6.0 ..."), this behaves like this:
(ie-1) Run pprPage.jspx in JDeveloper, which results in a page that shows this:
selectOneChoice A [null value label] some null related value, ...
selectOneChoice B [null value label] some null related value, ...(ie-2) Select "first choice label" from the "selectOneChoice A" dropbox and immediatly after that select "fourth choice label" from the "selectOneChoice B" dropbox, which results in a page that shows this:
selectOneChoice A [first choice label] some first-choice-value related value, ...
selectOneChoice B [fourth choice label] some null related value, ...(ie-3) Select "second choice label" from the "selectOneChoice A" dropbox, which results in a page that shows this:
selectOneChoice A [second choice label] some second-choice-value related value, ...
selectOneChoice B [fourth choice label] some fourth-choice-value related value, ...Using Firefox 2.0 ("userAgentHelper.info = ... Firefox/2.0.0.12"), this behaves like this:
(ff-1) Do the same as in step (ie-1), which has the same result as step (ie-1).
(ff-2) Do the same as in step (ie-2), which results in a page that shows this:
selectOneChoice A [first choice label] some first-choice-value related value, ...
selectOneChoice B [fourth choice label] some fourth-choice-value related value, ...
questions:
(q1) Why does the related information, for the selected "fourth choice label", not show up in step (ie-2) (as it does in step (ff-2))?
(q2) Why does the related information, for the selected "fourth choice label", show up in step (ie-3) while the value was only/already changed in step (ie-2)?
(q3) Does some general approach exist to prevent "simultaneous partial page rendering" behaviour as described in (q1) and (q2)?
many thanks

Can we implement partial page rendering on item style Flex??

Hi All,
In an xml,
I have item style 'Flex' for expense account.
Requirement is :
In the same page i have other LOV which brings the data based on one of the segments of that expense account.
So any changes in one of the segments for the expesne account need to be stored and LOV query should be modified accrodingly..
So trying with following possibilties
1) Use partial page rendering for expense account
2) Split the page into two so that first expense account is displayed and any modifications to it are handled in controller and use LOV Mappings to update the query.
So can partial page rendering can be implemented for Item style "Flex".
Can anyone please provide the inputs to handle this scenario and best possible solution?
Issue is very hot right now.. Quick help needed..

Hi
No u can not use PPR for flex items although u can create context flexfield .
thanx

Speeding up page rendering

Hi *,
Does anybody know some tips & tricks to speed up page rendering?
I have made a complex MVC application with tons of elements in each view.
When I test the pages on my PC, it works fine (my configuration resembles a small server), but when I test it on regular PC (PIII 500Mhz with 256 RAM) the browsers shows DONE in the status bar, but I see a white screen for 10 to 15 seconds.
I did some runtime analysis and found out that the problem lies not with the application, nor with the network, but purely with Internet Explorer.
I kicked out some htmlb elements which were only used to fancy-up the page, and sticked to pure HTML as much as possible, this improved rendering by 15%, but still the rendering is very slow.
Does anybody know some other tricks to speed it up?
Thanks in advance
Mario Vangerven

Sounds very strange. The drawing of the page elments can not take so long.
I guess that the problem is not in the rendering.
Check the HTTP trace of the browser. I suspect some unavailable of 'long-accessible' resources there.

Partial Page Rendering - newbie question

I am a newbie to ADF and I am in the process of trying out the tutorial "Developing Ajax-Based User Interfaces with ADF Faces Rich Client Components" http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_56/jdtut_11r2_56.html
I have a question regarding Step 4. I am not very sure where to post this question, if this is not the correct forum, pardon me.
Under "Step 4: Implementing Partial Page Rendering" there is this following comment
In order to have a refresh of the Product Details when you select another row in the Product table, we need to set the Partial Rendering behavior. To do so, perform the following steps:
Similarly On Step 3, sub step 26 states "Finally, double-click on any of the rows in the product table. Notice that the Product Details pane does not reflect the change in the selected product. To implement this synchronization, we need to add partial page rendering functionality."
Question: even before I tried any of the changes mentioned in step 4, I am finding that the product details pane does show information related to the product selected on the panel collection (in other words it is displaying the master detail information automatically). What am I missing here? As per the training document it is supposed to work only after implementing changes mentioned in step 4. Can one of you kindly point out if this is a mistake in documentation or if I have misunderstood the statement?
Thanks
A Sreedhar

Frank,
Thank you very much for the quick turnaround; I appreciate it.
Yes, I am using what seems to be the latest version of JDev (11.1.2.3.0); and yes the ChangeEventPolicy for the iterator is set to "ppr". Thank you for pointing that out.
Does that mean ppr is standard for most components (when I say components, I mean adf tables, button's etc), don't we need to add any special events to get that to work?
I just wanted to see, what will it due if the ChangeEventPolicy for the iterator is set to "None"; made the change saved it, there were two iterators I changed the "ChangeEventPolicy" on both to none; saved it and ran the page. It worked same as before; I was expecting it will not load the corresponding data at the child level, but it did. can you kindly point out what is wrong.
<executables>
<variableIterator id="variables"/>
<iterator Binds="root" RangeSize="25" DataControl="StoreProducts" id="StoreProductsIterator"
ChangeEventPolicy="none"/>
<accessorIterator MasterBinding="StoreProductsIterator" Binds="products" RangeSize="25" DataControl="StoreProducts"
BeanClass="tutorial.model.Product" id="productsIterator" ChangeEventPolicy="none"/>
</executables>
Thanks

Slow Page Draws

Ok here is the problem when ever I add a SELECT statement to my code it just gets slower and slower. Without the SQL statement it takes less than 1 second to draw the page, with the statement it is taking over 3 seconds. For every Sql statement I add to the page it takes about 2-3 seconds longer to draw so 3 Select statements would take almost 10 seconds to draw tha page. All of this is running locally on a Win2003 Web Ed. Server running Tomcat 5.0.24 and MySQL version 4.x. Here is the code

Ok here is the problem when ever I add a SELECT statement to my code it just
gets slower and slower. Well what would you expect?
You are adding
1 - database processing time
2 - jsp code accessing the data
3 - page rendering.
My guess is that the time will mainly be spent on the database processing. Looking at your page, you don't seem to be doing much more than spitting the data straight back out.
Couple of things to speed things up
1) Use database connection pooling.
Currently every time you run the page it creates a new connection to the database. This is quite a bit of overhead in the scheme of things.
The easiest way is to set up a JNDI datasource in Tomcat:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.html
However instead of modifying server.xml like that page says, I prefer adding the resource tags into a context.xml file as specified here:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/context.html
The settings remain exactly the same, just they are in a different file.
You then change your setDataSource tag to use this JNDI name
eg
if you created a resource under the name: hrpData
<sql:setDataSource var="dataSrc2" dataSource="hrpData"/>2) Tune your queries.
select * from linkexcatalog where parentid= ${catid} order by catalogname
consider indexing the table linkexcatalog to speed up the query. An index on parentid field would let the query run faster.
3)
I am also a fan of using prepared statements and the <sql:param> tag rather than putting the ${catId} parameter directly into the query. That also might make it more efficient.
Hope this helps some,

Very SLOW Pages 09 when not connectec to the Internet. !!!

Hi:

The thing is today I had no internet at my house and I noticed that pages '09 was Very SLOW openning and Saving My document. I tried with other documents and they all behave as the one described before.
I Describe the document because I have seen posts here of slow pages due to document structure. But I dont think this is document related because it happened it all the documents i opened and even just loading pages. My machine was as allways, all the programs running great except Pages.
I also noticed that when Arrived at work and connected to the internet the Slowliness had ENDED.
Anyone knows what is happening??

There are ways to stop this behavior. The best is to use *Little Snitch* which allows you to stop certain connections being made. Basically when the attempt to connect is made, *Little Snitch* intercepts it and lets you choose: Allow, Allow once, Disallow once, Disallow forever.
4 Users who had *Little Snitch* also noticed that Pages '09 was trying to connect to a web advertising site. Why this happens, ask Apple.
Too late, Apple removed the task

Too msuch wait time for APEX page rendering

==================
This is based on the thread at Too much time on network wait!
Referring back to the thread above which seems to have gone 'cold' and for some strange reason the second page of that thread no longer appears/exists.
But on that second page someone mentioned the solution below (with the idea that the EPG was causing the issue of pages rendering slow. Page render fine using Glassfish in another environment).
exec dbms_xdb.cfg_update( updatexml( dbms_xdb.cfg_get(), '/xdbconfig/sysconfig/call-timeout/text()', '300', 'xmlns="http://xmlns.oracle.com/xdb/xdbconfig.xsd"'));

Thank you.

the idea that the EPG was causing the issue of pages rendering slow. Page render fine using Glassfish in another environment). Probably the value of the SHARED_SERVERS parameter needs to be increased.

Shadow and gradients slow page load...why?

I have read how shadows and gradients slow down a web site, and that you should replace them with (essentially) screen shots of the same (i.e. looks the same, but not using the shadow or gradient feature of iweb).
I understand that larger photos (etc) slow down a page load, but I don't follow why these do. I am curious for an explaination. It would seem intuitive that the apple folks would publish a web site in a way that did not cause this (i.e. covert shadows and gradients to jpgs or something).
thanks
bob

Shadows and gradients generally actually don't cause professional designers any issues, how you design it and what file format is important, most produce high quality images with a low impact to the web page load time. I have been designing for over 20 years and quite like iWeb challenges .
iWeb however does something quite different, it adds to an existing image, mainly using javascript which slows the rendering and page loads. iWeb works great for non professionals as it's dreadfully poor from a site point of view, remember iweb is a toy in the software world of web design tools, so enjoy it for what it is..
A simple way to prove is to design a single page in iWeb and the another using, say, Dreamwever, look at the rendering/load times.....

Slow page rendering due to a LOV!
