Wwv_flow.accept - 'page cannot be found' error

Hello,
We are currently having problems where we are trying to upload files and sometimes we are getting the wwv_flow.accept - 'page cannot be found' error. Sometimes we can upload the file and then sometimes we get the error message and is very random.
We have checked the marvel.conf file and the PlsqlDocumentTablename parameter is set to wwv_flow_file_objects$ so that's not it.
We have checked the apache log and all we can see is the following error message:
[Tue Jul 17 15:20:22 2007] [error] [client 10.200.36.18] [ecid: 79243024857,1] mod_plsql: /pls/htmldb_test2/wwv_flow.accept HTTP-404 ORA-01401:
inserted value too large for column
So does anybody have any ideas? As I said its seems a bit random as sometimes we can upload the file and sometimes we can't and get the error.
We are currently using Apex 2.2.0.00.32.
Thanks in advance,
Paul.

Hi Scott,
Yes when we try and load the same file, 70% of the time it doesn't upload and 30% it does so I can't really say what the problem is.
Here is the DAD info:
<Location /pls/htmldb_test2>
Order deny,allow
PlsqlDocumentPath docs
AllowOverride None
PlsqlDocumentProcedure wwv_flow_file_mgr.process_download
PlsqlDatabaseConnectString test2 TNSFormat
PlsqlNLSLanguage AMERICAN_AMERICA.AL32UTF8
PlsqlAuthenticationMode Basic
SetHandler pls_handler
PlsqlDocumentTablename wwv_flow_file_objects$
PlsqlDatabaseUsername APEX_PUBLIC_USER
PlsqlDefaultPage apex
PlsqlDatabasePassword <password>
Allow from all
</Location>
Our database version is: 9.2.0.8
Character Set is: UTF8
I will ask our DBA to see if he can apply this patch too.
Cheers,
Paul.

Annoying page cannot be found error

Hi,
Can any one give me any direction in what I'm doing wrong here.
I have an app, that I've put on apex.oracle.com, that is used for mapping values from one table to another.
http://apex.oracle.com/pls/otn/f?p=44423:800
The first bit works fine, you select from a number of drop down lists and this dynamically builds two list of values.
The problem starts with the filter option. There is a text filter and an order by option and both work fine individually but when both functions are used i get a page cannot be found error
Is this a problem with my coding or a problem with apex??
Regards Andy

Hello Andy,
I quickly had a look at your app and wondered why you sometimes do an instr and sometimes do a like %...% ? Why don't you always do an instr?
To me it looks like the building up of the SELECT statement is incorrect.
If you try to put in the where only 1 condition and build from that, you should be able to find your mistake.
Hope that helps,
Dimitri

"XML page cannot be displayed" error

Using XML output on a table with more than a few rows falls over with a "XML page cannot be displayed" error. Sometimes only the error is displayed, sometimes some rows are displayed with this error at the end of the page (eg the DEMO_STATES table)
Can anyone advise if there is some sort of limiter at work here?
Thanks,
Barry

i'm pretty sure that error comes up when your browser (ie, specifically, i believe) can't render the xml data it's received. i'm also pretty sure, as the full message implies, it's because it doesn't know what style sheet to use when you go to that page. in short, it's a browser config issue. one way to bypass it (to at least prove that it's a browser issue) would be to create a link to your page, right click the link, and do a "Save Target As...". the resulting file will be your valid XML one. fwiw, i've had better luck controlling the manner in which my xml data is received when i use mozilla or netscape (but i'd imagine there's just some setting you'd toggle in IE to avoid your issue).
hope this helps,

"Page cannot be found" error when submitting tabular form

One of our developers has used a wizard to create a tabular form with the intent or providing an interface for updating one of our tables. The page runs correctly up until the point when the user clicks the Submit button. The user is then re-directed to a "page cannot be found" error page. I checked the apache error log and I'm seeing this error (ip addresses hidden):
[Wed Oct 13 06:37:59 2004] [error] [client x.xxx.xxx.xxx] [ecid: 1097674679:x.xx.xxx.xx:7286:0:23738,0] mod_plsql: /pls/htmldb/wwv_flow.accept HTTP-400 Too many arguments passed in. Got 2009 parameters. Upper limit is 2000
We have pages in other applications that were built the same way, and can't figure out why we are seeing these errors.
Any ideas?
Thanks.
Matt

Sorry I didn't want to take the time to import the application, create the data structure and populate it, when the page is now working. However it seems like you should be able to easily re-create the situation. All I did was go through the wizard for a tabular form. It was based on a view and displayed all the columns, most of them updatable. It seems like what makes it fail (error when either CANCEL or SUBMIT is clicked) is just having a lot of fields on one screen. I base this conclusion on the error message from the Apache error log (mod_plsql: /pls/htmldb/wwv_flow.accept HTTP-400 Too many arguments passed in. Got 2134 parameters. Upper limit is 2000) and on the fix of reducing the number of rows on one screen, using pagination.

"Page cannot be displayed" error when attempting to download large dataset.

In the following code, can anybody please tell me at what point the data actually starts to get transferred and the popup "download file" box appears? I'm thinking that the dialog box should appear on the first outputstream.write and start transferring data. However, I think it's not transferring the data until the while loop has finished! That's bad because this is a real long process and I eventually get "Page cannot be displayed" error. On a smaller dataset (shorter while loop) everything seems to work correctly. Is there some sort of a web server configuration that tells it to write out the data ONLY if outputstream closes? I really need it to write out the data as it's coming in. Code is below and thanks in advance.
response.setHeader("Expires", "0");
response.setHeader("Content-disposition","inline;filename=Download.csv");
response.setContentType("application/x-msdownload");
outputStream = response.getOutputStream();
bufferInBytes = this.getData();
while (bufferInBytes != null)
outputStream.write(bufferInBytes, 0, bufferInBytes.length);
outputStream.flush();
bufferInBytes = this.getData();
outputStream.close();

Hi All,
Thanks for all your help.
Seems I already found out the issue.
Since we are using "Personal Home Page" for the system profile option "Self Service Personal Home Page Mode" I checked oracle note and found out
that 11i did not support this mode. Maybe this is the problem that is why we are getting page cannot be displayed error when only 1 responsibility is active.
The way to fix this, is to use mode 'Framework Only' instead of 'Personal Home Page' as Oracle are phasing out mod_plsql based UI and it will not be present in future releases. No maintenance is being performed (i.e. bug fixes) to the mod_plsql based UI technology.
Please check this note for more clearer explanation:
Is The 'Personal Home Page' Mode Supported In Oracle 11i Applications? [ID 368628.1]
Again, thank you for your help!

Page cannot be displayed' error when 2 events (FireAction and GO) fired

We have created a framework page where FireAction event will be executed
when the value of a calendar item is modified. When we modify the
value and leave the cursor in the field (without tabbing out), and click
GO button, 'Page cannot be displayed' error message will be displayed.
When FireAction event is started, we use CO to retrieve the event. And
when the cursor remains in item1 after being modified and click GO,
2 events will be started (the FireAction event and the GO button's event)
and 'Page cannot be displayed' error will be shown since CO is retrieving
2 events at the same time.
Since by changing certain fields of framework page without tabbing out
is a regualar operation, how can we go around this error when we are
using FireAction event?

Shive...good one..!!
One thing that you can do if you don't wanna have PPR, is to validate date column in fire action event in CO in process form request, and raise an error if you don't find appropriate format or null , as per your requirement.

"Page cannot be displayed" error in EBS R12

Hi All,
We implemented EBS R12 with 2 Application Node, 2 CM nodes and 2 DB Nodes(RAC). We have also setup load balancer at the application level. We have enabled HTTPS at the load balancer level. Our application works perfectly fine except some of the PIM module related screens and especially Workflow Manager, it gives us "Page Cannot be displayed" error sometime. What we have observed is, Our URL is https://ebs.abcltd.com but when we click on Workflow manager link under Oracle Application Manager, the URL gets redireced to http://ebs.abcltd.com:443/. We would like it know why this redirection is happening? as we have not mentioned this (http://ebs.abcltd.com:443) url in our context file.
Thanks,
Prasad

Hi Prasad,
Can you find any errors in Apache/Workflow/Database log files when this error occur?
Did you verify the session persistence on the load balancer? -- See the documents referenced in this F5 Load Balancer with Oracle 11i.

Hussein

Page cannot be displayed error while accessing links on DAS page

Hi,
I have installed SSO server along with DAS on a single m/c. While installing i gave OID instance hostname and password. After installation when i access the DAS homepage and click on Login or Myprofile url is is throwing Page cannot be displayed error page
i found following in the Apache\logs\error.log
[Wed Nov 23 10:28:26 2005] [error] [client 198.186.43.113] [ecid: 1132759706:198.186.43.113:2408:2136:6,0] MOD_OC4J_0376: Request initial processing failed in ac worker with HTTP status code 1. This status will be passed back to the listener for error handling.
I checked OC4J_SECURITY and HTTP_Server status. They are up and running. OID is also running.
Any solution for this problem?

Hi,
I once faced a similar problem - I am not sure if the issues are related, but here goes :
I figured out that DAS uses mod_osso to connect to the SSO Server. I hadn't configured mod_osso to correctly talk to the SSO Server. I used the ssoreg.sh script in the $ORACLE_HOME/sso/bin to make the mod_osso " talk " to the SSO Server.
After this, the DAS started working properly.
BTW, what's your AS instance version ?

Page cannot be found errors

Using MacBook 3.1 running OS X Snow Leopard, I am getting random "page cannot be found" errors, or the inability to load images, usually on specific sites. Google, Facebook, and Amazon were giving the most trouble yesterday. Now it's happening with more sites. Firefox is my primary browser, but I get same results in Safari and Chrome. Other computers using the same connection just fine (both Mac and PC). My MacBook connects fine when connected to on other wi-fi networks or using my cell phone's 3G.
I have tried clearing all kinds of cache (and in Firefox it's currently overriding to store 0 MB cache) including:
1. User Account/Library/Caches - delete everything inside the caches folder.
2. System/Library/Caches - delete everything inside the caches folder then restart.
according to this discussion: https://discussions.apple.com/thread/2331995?start=30&tstart=0
I've also read through this discussion: http://mac.bigresource.com/OS-X-Leopard-Some-Sites-including-Google-Does-Not-Wor k-w6GTVWfnY.html
Seems everyone else fixes the issue by removing Peer Guardian. I've never heard of that program and don't have it installed (or any other filtering software for that matter).
fwiw, the problem connection is a DSL line provided by Cincinnati-area ISP called zoomtown. (Maybe other Mac users have had similar issues with them?) Obviously I'm going to call the ISP (though I'm not hopeful they'll have a clue) and see if the local Apple Store has heard of this issue with Macs on this ISP. Unfortunately, I probably cannot duplicate the issues at the store.
Appreciate any advice if anyone's had this kind of issue before. Thank you!
Jason

May have found the culprit within my DNS settings. It's worked for the past 5 minutes at least, while testing several of the problem sites with no errors.
Going into my AirPort settings, I had a DNS address of 4.4.4.4. I deleted that one and now have the addresses to OpenDNS at 208.67.222.222 and 208.67.220.220.
More info: http://macs.about.com/od/faq1/f/browserdns.htm
We will see if this proves to be a permanent solution.

Getting "Page Cannot be displayed" error when calling a procedure

Hi all,
I have a page having a table with more than 2000 rows. On click on save I need to call a pl/sql procedure and then a concurrent program and then based upon the result of CP I need to update the records from the back end.
All this is done on the click of save button. Now my issue is the concurrent program takes a long time to get completed and I get "Page cannot be displayed error" on my page. Is there any way by which on click of save button I can redirect user to some other page saying the CP has been submitted and at the same time my CP and Pl/SQl procedure will be called. Here I have only one constraint that after competitions of my CP I need to update my table as well. So I need to handle that part as well.
Regards,
Arvind Goel

hi
would u please share ,how r u calling concurrent program ???
thanx

"The Page Cannot Be Displayed" error when clicking the Remote Agent

Hi everyone! We have installed ACS SE 4.0 and we have added a remote agent running on Windows Server 2003. Recently, we are encountering "The page cannot be displayed" error when we click the RA under a network device group. This is resolved by rebooting the ACS SE appliance and accessing the ACS SE web console again but after few hours, problem reoccurs. Clicking the links on the ACS SE web console is okay at first but after clicking the RA, every link shows the error "The page cannot be displayed." Hope you could help us on this problem. Anyone's support is very much appreciated.
Thanks!

Hi JG,
Thank you so much for your response. Does Cisco have a documentation that states that this is a known issue with 4.0, such as release notes, for we might need this for the proposal upgrade?
Again, thanks a lot!

Radio Button Selection gives "The page cannot be found" Error

I have a Radio Button that has 4 chooses, one of the choices has Javascript to ask a Prompt and uncheck it depending on the user response.
When I select the one that has the prompt, it works as expected with the question, however when I click the Submit button on the page to fire my database trigger it fails with "The page cannot be found".
All the other choices, once picked update the datasbase ok.
Any idea's from anyone why I'm getting this error?
script type="text/javascript">
function yesno(msg,item)
if ($x(item).name = 'PF' && $x(item).checked)
confDel= confirm(msg);
if (confDel != true)
{$x(item).checked = false;}
</script>

Preethi,
When I click on submit button ,iam getting " The page cannot be found" error.
When you run the page and click on its submit button, you get the error. Being careful to distinguish problems you get at design time vs. those you get at runtime is extremely important when you ask others for help here.
I looked at the application. In your problem description, you gave absolutely no information that explains what you are doing on this page. Whatever it is, the problem is that you are creating HTML items on the page with names like
name="f60"
Then when you POST the page, you get an error. That's because those "fxx" items are limited to the range "f01" .. "f50".
