Application Certification With APEX 10G XE

Hi all,
Has anyone implemented Application Certification to the application developed in Oracle Application Express 10G XE? My requirements are:
Accessibility - check against WCAG and Section 508 guidelines
Usability - check against Usability.gov and W3C guidelines
HTML standards - check against W3C HTML, XHTML and CSS standards
Browser compatibility
Can anyone help me implementing these things? Please do reply if its not feasible too. Thanks
With Regards,

That's quite a lot to handle all at once if you've no previous experience...
Start with the easiest:
HTML standards - check against W3C HTML, XHTML and CSS standardsThere are online HTML and CSS validators all over the place.
There are also lots of Firefox plugins available. One we have made use of is Total Validator as it also includes accessibility recommendations and spell checking. It's also available as a standalone program on some platforms.
Accessibility - check against WCAG and Section 508 guidelinesThe (often questionable) output of the online accessibility tools is useless if you don't know how to interpret what they are recommending – and often more importantly whether it's actually useful or not. The best resource by far is Joe Clark's book Building Accessible Websites, available online to read for free. (It is – perhaps surprisingly given the subject matter – one of the most readable books about the web available.)
Usability - check against Usability.gov and W3C guidelinesNot an area I'm very familiar with. If you're going to do it right then you need to perform proper usability testing, probably by engaging a specialist usability consultant.
Browser compatibility1. Code to standards.
2. Define browser support requirements, allowing for graceful degradation in less supported browsers.
3. Test test test.
The latest UK Government guidelines on browser testing have met with support in the standards community, and provide good advice on how to proceed.
You then need a test environment that provides all the browser versions you are going to support. This is complicated because certain vendors don't make it easy to install multiple versions of their browsers simultaneously, or you might have requirements to test several browser and OS version combinations. The best approach to this is to use VMs: they're isolated from your developer/organisation builds, so you won't break anything internally; you can build up a library of test environments as browser and OS versions change; they're disposable if they get hosed by hacks (e.g. to install multiple browser versions).

How to create Application Workspace with Jdeveloper 10g 1.3.2?

Following the instructions in "Developing and Using ADF Faces Skins", I am trying to create an Application Workspace.
The instruction says: "In JDeveloper, create a new Application workspace and name it - ADFFaces_skin_sample"
I can not find the way to create Application workspace with Jdeveloper 10g 1.3.2.
Because when I click FILE==>New I got "New Gallery--Application" in left, in right only got "Application, Empty project, File, Java Class, Java Interface". There is no "workspace" item.
I try to use Jdeveloper 10g 1.3.1, got same result.
I found other ADF Skin training samples. All of them asked to create Application Workspace. But the Jdeveloper version used by all those samples were earlier than 10g 10.1.3.2
Please let know how to create "Application Workspace"?

What used to be "Application Workspace" in 10.1.2 is "Application" in 10.1.3.2

Use dataguard with applications built with APEX

Hi all,
I have questions about APEX with Dataguard. Can I develop an application with APEX and then use Dataguard? Can the application switch to Standby Database automatically when there is a failover event?
If it is possible, Can you explain me?
Thank in advance
Vincenzo

APEX should work fine in a Physical Standby as it's an exact copy of your database. Logical Standby should work too, but you need to make sure the FLOWS_ schemas are being replicated and there is no transformation done to them. Also not sure if there are any datatypes in APEX that would not work in a Logical Standby, but you should be able to look those up in the Data Guard Docs then query all_tab_columns where table_owner like 'FLOWS_%' to verify. Physical Standby would be a safer bet.
You want to make sure you install your HTTP server on a different server so it doesn't go down with your database in the event the OS shuts down. Then in the TNS entry for your database you can add [url ="http://download.oracle.com/docs/cd/B19306_01/network.102/b14213/tnsnames.htm#sthref676"]failover=on and the additional IP address(es). This will automatically failover when your primary database is no longer accessible. Personally I would have a second HTTP Server installed at your backup site and handle the failover at the network level. If a sprinkler head pops or your air conditioner fails at your primary site, everything is going to stop there. You can easily have 2 HTTP servers accessing the same APEX install (on one database) at the same time, so it's easy to test / verify the state of the 2nd http server. You'll probably want to mirror the /i/ directory and any image directories you have for your applications from your primary site to your failover.
"Automatically"? Yes, all of this can be configured to happen automatically, but most people (Tom Kyte included) recommend that you only failover manually as it's best to investigate the underlying issues with your primary site before failing over. You should be able to tell within the first 5 minutes whether the problem was a simple network outage or unintentional OS reboot, or a more serious problem such as a corrupt block, Air Conditioning failure, hardware issues, etc. Keep in mind to do automatic failover you need a 3rd site as an observer of your 2 sites to decide which site is "still alive".
Varad, I believe TAF is only a RAC concept, not Data Guard. Furthermore, I'm pretty sure that TAF is not built into APEX. So, in an APEX / RAC installation, if you're running a page that takes say 4 seconds (long running report) and 2 seconds in the database node on which you are running fails, the end user is likely going to see a "404 not found" or some other error, then when they refresh the page it will hit another RAC note and return the results. I'm pretty sure the TAF logic is not built into APEX or mod_plsql to migrate the database session to a new surviving node when it detects a failure. Again, I could be wrong, but I'm pretty sure I'm not in this particular case (someone please prove me wrong).

EBS 11i Adaptor certification with 9iAS/ 10g AS Interconnect and FMW 11g

I'm trying to get three compatibility questions answered regarding the 9iAS / 10g Interconnect product to assist with upgrade planning:
1. Is the EBS 11i Adaptor with 9iAS Interconnect certified when the underyling EBS database is Oracle 10g? (the certification page is not specific in this regards, it doesn't mention the underlying database release)
2. Is the EBS 11i Adaptor with 10gAS Interconnect certified when the underyling EBS database is Oracle 10g?
3. Does the EBS 11i adaptor for Fusion Middleware 11g work against an Oracle EBS 11i that is running on a 10g database?
Thanks.

Hi Pritesh,
With Pleasure brother
Is the oracle application server 10g is required to install in my case.
No, You don't need to worry about this, as you are not working with Portal.
But just to clarify:
When you upgrade from 11i to R12 application, then 10g Application Server will be automatically configured as R12 Application uses 10g Application Server by default.
Please refer note:
Interesting Documents Concerning E-Business Suite 11i to R12 Upgrades (Doc ID 850008.1)
Database Preparation Guidelines for an E-Business Suite Release 12.1 Upgrade (Doc ID 761570.1)
Planning Your Oracle E-Business Suite (EBS) Upgrade from Release 11i to Release 12 (Doc ID 1406960.1)
Installing Oracle Application Server 10g with Oracle E-Business Suite Release 11i (Doc ID 233436.1)
Hope this clarifies
Thanks &

Upgrade from 11i to r12 application servers with Discoverer 10g

Hello, one and all.
I have recently upgraded from 11i to r12 Oracle financial application server, after much patching and testing we finally came to the Discoverer application server.
Most workbooks open fine, however it seems that some of them (about 3%) reference columns that no longer exist in r12, for example, SET_Of_BOOKS_ID has become LEDGER_ID in r12 on the gl.gl_je_lines table.
This causes any workbook that references that business area to return an error 'Database Error - ORA-00904: " O974567"."SET_OF_BOOKS_ID": invalid identifier.
Well and good; I think that that's caused by the EUL not being refreshed after the upgrade, so I go to the Discoverer administrator and refresh the general ledger Business area. This unfortunately renames several objects inside the business area, including SET_OF_BOOKS_ID to LEDGER_ID, so instead of that error, we now get several 'Missing item or condition' errors until the workbook will not open at all with an 'Item dependency "" not found in the EUL.' error. This i assume is because the workbooks still reference the old items.
I'm guessing that several Business areas and objects therein have been renamed since nearly none of the workbooks will open now. I have restored the EUL from a backup (imported all the *.eex files) however I was wondering if anyone had faced this issue.
I apologize as I have very little understanding of Discoverer and this might be a simple fix, but I'm at this point willing to try anything for help.
Thanks!

Hi Srini
Srini,
To understand your above reply,
You say that
1) If they are based on 11i Discoverer EUL and Folders then export EUL And WorkBooks and Import them
into R12 Discoverer Environment..Refresh the EUL..So ORACLE will take care of the changes like 11i SOB vs R12 Ledegrs??Pl open a SR with Support on what to do with seeded EUL as part of this upgrade - I suspect you will need to import the R12 EUL as part of this upgrade.

2) If they are Custom SQL reports from 11i then just RECREATE them from SCRATCH..Correct - after you verify that they are changed to reflect the R12 data model

Am I right?

Issues in integrating 10.1.3 Application server with APEX

Hi
I want my apex applications to work both using 9iAS and 10gas (10.1.3). There is a requirement for this. So I am using this document
http://download.oracle.com/docs/cd/E14373_01/install.32/e13366/otn_install.htm#CHDFJBFB
section 3.4.5.4
In 9iAS we used to define aliases for images in httpd.conf and dad setup in wdbsvr.app; looks like it is consolidated in to dads.conf now. So I put entries as per the document above.
1. What is the equivalent of cgi_env_list that exists in wdbsvr.app in dads.conf? I have to define this I think.
2. Similarly is their equvalent directive for stateful = STATELESS_RESET in dads.conf?
3. When I try to access the URL , I get this message in access log

I am able to connect to sqlplus from the middle tier where I am trying to set this up and tnsnames.ora exists. Not sure why it is complaining about listener on the client machine.
Any idea?

I solved 3. Basically I had wrong values for dbhost name :(
If anyone can provide answers for 1 and 2, that would be be nice.

APEX application problem with Apple's Safari browser

Hello Everyone,
I'm working on Apple Safari (version 4.0.5) with Oracle APEX 4.0, the APEX development environment is working fine, but when we try to run our application, after login, while switching tabs, our application hangs with the following URI in the browser
xxx.xxx.x.xxx/apex/wwv_flow.accept
and page is rendered blank, even the page source view is blank.
Our page also carry some JQuery related code functionality, along with regular HTML and Stylesheet.
No idea what is causing this behavior?
Our application is running smooth with browsers like IE, FF, Opera.
Sample applications provided in-bundled with APEX 4.0, are running good on Safari as well.
So kindly suggest, what could be the possible reason behind this?
Regards,
Krishna

Hi Patrick,
Yes, I'm using my own custom made theme also involved JQuery javascripts & functionality on apex pages.
I'm using Safari 4.0.5, didnt checked with the latest version yet.
Yes I've tried it on Google Chrome, its working fine, except with the already know issue, that on each page's post-back, chrome prompts for the XDB Username and Password, which is also a very major issue with my application.
I've gone through various threads from OTN to look out for the possible fix to this issue, but not helpful so far. Have tried few alternatives suggested on OTN, after which landed up in more complex issues causing my application to prompt XDB credentials on all the browsers. Now some how have brought the application back to the previous state, with the help of OTN indeed. Presently my application execute fine with IE, FF & Opera, except Safari & Chrome (XDB credentials prompt).
It would be really not an easy task for me to replicate the same scenario on apex.oracle.com, because it involves various database tables too.
I'm wondering, you asked me the 'theme' subject for the issue, kindly would you please educate me more, how themes can cause an improper functionality on Safari and not in rest of the browsers?
Thank you so much Patrick, I'm partially relieved knowing that you responded me. Great pleasure learning from you.
Regards,
Krishna

Advice Needed: Installing APEX 4.2.1 with SSO 10g

I am running in an environment here where it is mandatory that I run SSO 10g (the old verison 10.1.x.x OAS based). How do I go about enabling SSO in APEX 4.2.1? Can I use the same ssosdk902.zip I used with APEX 3.x.x or do I need a different one? There is no plans to go to upgrade off of our legacy 10g SSO or go to OAM based SSO. I would appreciate any information that can be offered.

Hi David,
yes, you can use the same SDK. You just have to take care to follow the same steps. It's easy to forget to re-create synonyms and do grants after an APEX upgrade.

Oracle Developer 6 applications with database 10g

Hello,
My all applications are developed and running in Oracle Developer 6 with database 9i. But now i want to use
database 10g with these Oracle Developer 6 build applications.
Already compiled files (with dev 6 and DB 9i) are runing with database 10g quite nicely,but when i try to
recomplie the source files of these applications with 10g database i got the fowlloing error.
ORA-00600: internal error code, arguments: [17069], [45468896], [], [], [], [], [], []
After it i open these Oracle Developer 6 applications source files with Oracle Developer 6i and use 10g database,
compile and run very easly.
I think it is old version problem .But my development team dont want update all applications to new version (6i or other) yet.
Is there any solution to use Oracle Developer 6 applications with database 10g ?
Thanx.

The general rule is "Ora-00600s (and 7445s, 3113s) are to be reported to Support". Look in Metalink to see whether any one else has reported it, based on the first argument. If so, there may be a workaround or a patch.
Since you are asking this generically without database version, patch level or operating system, I assume you are using the unsupported free download and do not have access to Metalink. In that context
1) What is the problem:
The problem is your request (QSL, PL/SQL, Java) is hitting a bug or abusing a part of the Oracle software in an unexpected way. ORA-00600 is simply one of the 'unexpected and unhandled exceptions'.
2) Required action:
Since it is unexpected and unhandled, there are several ways to proceed:
- Search the net for the first argument (ktspgetmyb-1) to see whether someone has a workaround
- Reproduce and Simplify your offending code until you find your own workaround.
Often this happens with some sql statement

Forms 6i based application compatibility with Oracle Lite 10g

My client is currently using an Oracle Forms 6i based application (together with a Jinitiator)
in an application deployed to 50 countries using Oracle Lite 9i as the Mobile Application Server and Oracle 8i as the database.
We are considering an update to Oracle 10g database and 10g Rel 3 mobile application server.
Can anyone advise on the impact of such an application on the Forms 6i application and if there is a recommended process for the upgrade of the forms application?

do you mean the OAS 10g Rel. 3 ? That application server has no forms-component. Only the Rel.2
Your Forms 6i is certified against 10g databases with patch 17 and 18. Download them from the metalink.oracle.com

Can 10G express be used to create an application for use with a 10G instanc

Hi
Can 10G express be used to create an application for use with a 10G instance? I am new to Oracle 10G. I like the interface for creating applications, maintaining users, etc. Can this tool be pointed at a regular instance of 10G so that applications can be created against a regular 10G database not the express database?
Can PL/SQL proceedures that are created in 10G express also be migrated to a 10G database?
Thanks in advance
Dean-O

Can 10G express be used to create an application for use with a 10G instance?Yeah, that's the whole point from a marketing perspective ;)
Can this tool be pointed at a regular instance of 10G so that applications can be
created against a regular 10G database not the express database?Yes but it's a different version. Check out:

Create PDF report with APEX and Oracle 11g doesn't work

Hi everyone,
I have a problem with the downloading of PDF reports from APEX with Oracle 11g.
When I try to download a PDF, Acrobat Reader says it can not open the file.
I have done the same test in an environment with APEX and Oracle 10g and it works perfectly.
Does anyone know if there is a known bug for version 11g.
Thank you very much.

Hi Munky,
I open the generated file the Notepad++ I can read the next message:
*<HTML><HEAD><TITLE>500 Internal Server Error</TITLE></HEAD><BODY><H1>500 Internal Server Error</H1>OracleJSP:*
An error occurred. Consult your application/system administrator for support. Programmers should consider setting the init-param <code>debug_mode</code> to "true" to see the complete exception message.</BODY></HTML>
I have not idea can I solve the problem.
Have you got any solution for this problem??
Thank you so much.

Anyone used PL/FLOW with APEX in Oracle 11g?

Greetings.
I'm trying to find out if any of you have successfully used SourceForge's PL/FLOW with APEX in an 11g environment. References to PL/FLOW seem to be limited to 9i and I need to have some assurance that it would be compatible in a more updated setting.
And do you have any advice on installation and use cases?
http://plflow.sourceforge.net/
Thanks very much!
Chris

Hi Chris,
I've used it in a 10g DB without any problems, I have no reason to suspect (without trying it) that it wouldn't work in 11g.
Did you try it, did you have some problems?
