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).
Thanks,
Tyler

Start working with APEX

Dear All,
I have Dev6i certification. I want to know
1) if it is possible to develop a database application with APEX with all Developer's functionalities?
2) How can I get complete guide or training on APEX?
Thanks a lot

Hi Khawar,
+>> if it is possible to develop a database application with APEX with all Developer's functionalities?+
Well, in general, you'll find that there are some things from client/server which don't have equivalent functions on the Web. Notice that I didn't reference just Developer 6i and APEX, this applies to really any situation when you go from client/server to HTML Web applications. In some cases, you'll find richer functionality in Application Express.
+>> How can I get complete guide or training on APEX?+
Well, you can start at http://apex.oracle.com. There are a number of links under "Getting Started".
Good luck

Need your suggestion / Input about choosing Apex for new application

Guys,
I came across oracle apex this week and started digging through the documentation and presentations. Read some forums as well. Now I believe, our application can be helpful by utilizing Apex but I would like to share high level application functionality which I am trying to implement through Apex
Following are the functionality of the application:
1) there will be 40 different entity in the application (create/edit/read/delete)
2) Each entity and CRUD processing will be roles based
3) On various events, send email and generate XML files for interfacing with external system
4) Scheduling report generation and normal report generation
5) Detail audit trail of the application (doesn't depend of Ajax, but still want to point out)
6) Various search capabilities for each entity
7) On various event and user selection: generate PDF file which user can download / print.
8) Many client side and server side validations.
Based on my reading, I believe this can be easily achieved with certainly some learning curve in AJAX. (which I have to do as I lost my entire project team due to budget issues.). I have a web devleopment background using Java, JSP and Servlet for 5 years. (Nothing in last 3 years though)
Please let me know your thoughts based on my current situation and functionality.
Also, Do i need to buy anything to get started with apex and implementing apex full blown application (they say it's free, but just want to understand your perspective as well).
Thank you for reading the post and your support.

At startup my chose application box pops with a question What is null? can someone please tell me what this is?

at start up my choose application box appears with the question "what is null?" can someone enlighten me on what this is?

The third-party system modification "GoFlex" may be contributing to your problem. I suggest you back up all data, then uninstall it according to the developer's instructions. Reboot and see whether there's any improvement.
Back up all data before making any changes.

APEX 3.2 Associating application with SSO login page.

Hi
My requirement is to replace my login page of APEX3.2 application with an SSO login page. Also, the application uses some tables with some history columns like: "Last Updated by", "Created by", "Last Update Time", etc... While create/edit of any table, I want these columns to be automatically populated according to the credentials used in SSO login page to that application. Please help.
The link given on this forum (http://www.oracle.com/technology/products/database/application_express/howtos/sso_partner_app.html) for the purpose seems to be obsolete i.e. for previous versions of APEX.
Thanks
Bhavesh

Bhavesh,
That how-to explains all the steps you need to set up SSO with Application Express.
As far as the audit columns, just create triggers on your tables. Referenced v('APP_USER') to get the authenticated username.

Help With "Package An Application" Using APEX 3.0.1 with XE

I'm using apex 3.0.1 and XE Database and I'm trying to create a package application but without succes, I can find the way to do it and I know that it's possible. What I'm trying to do is create a file like the package application that we can download from Oracle page but for an application I create.
Looking here in the forums I found this link:
http://www.oracle.com/technology/oramag/oracle/06-jul/o46browser.html
And I was trying to follow it step by step until I found the Step 4: Package Up the Application, number 7.
1. In the breadcrumb links in the upper left-hand corner of the screen, click the Application nnn link (where nnn corresponds to the ID of the employee lookup application in your Oracle Application Express instance).
2. Click the Edit Attributes icon, and then click Supporting Objects.
3. Click Edit.
4. In the Welcome section, enter readme text for the application in the Message field, such as "This application lets users browse employee information. Users accessing the application with a USERID stored in the table can upload a photo if one does not already exist."
5. Click the right arrow to go to the Prerequisites tab.
6. To ensure that folks who already have a table named OM_EMPLOYEES in their schemas don't run into a conflict with this script, enter OM_EMPLOYEES in the first Object Names field and click Add.
[b]7. Click the Scripts tab.
8. Click Create.
9. Click the Copy from SQL Script Repository icon.
10. Enter Create Table, Sequence, and Trigger in the Name field, and click Next.
11. Select om_employees.sql, and click Create Script.
12. Repeat steps 9 through 11 for the om_download_pict.sql and seed_data .sql scripts. Feel free to name these scripts as you see fit.
13. Click the Deinstall tab, and click Create.
14. Click the Create from File icon.
15. Click Browse, select the drop_om_objects.sql script (included with this column's download file), click Open, and click Create Script.
16. Click the right arrow.
17. Select Yes for Include Supporting Object Definitions in Export.
18. Click Apply Changes.
I can't find the scrips tab and I completely lost. I start to believe that this steps don't apply for Apex 3.0.1.
If anyone of you could help me with this, please do it, I really need it.
Johann.

Johann,
That doc was probably written against 2.2 because in 3.0, we reworked the supporting objects page a bit. If you are on Supporting Objects, in the Installation region, click on Installation Scripts. For more information, check the Advanced Tutorials document off our OTN site for a Tutorial called Reviewing a Packaged App (something like that - I can't access the doc at the moment).

I downloaded a job application with Adobe. What is your suggestion on editing it? What is the best way on my iMac?

I downloaded a job application with Adobe. What is your suggestion on editing this? What is the best way or best program? Thanks!

Simply, export the data from this esy share system to standard formats like jpeg, making sure to preserve all metadata on the way. How to do that? YOu'll need to post on a Kodak forum I'm afraid.
Then copy the files to the Mac and import them.

Deploying APEX application with web host

Hi guys,
Whats the process of deploying APEX application with a webHost?
We got a good deal from a web host with dedicated database, it still being processed.
Currently we have a domain name hosted elsewhere (non APEX host) . What I am planning to do is, create a subdomain with our existing web host and point it to the IP address of the DB machine the apex host will give us.
So I am guessing the process will involve:
1) getting the IP address of the database machine
2) configure the my existing web hosting setup to create a sub-domain and make it point to the IP address (for example 174.184.223.441)
Would I need Port number of the machine running Oracle DB with APEX and the local IP address (the one starts with 10.0.0.xxx) etc?
Would be grateful if someone can share what you did given you already have a domain hosted and need to create a subdomain to make it point to another APEX host.

Hi Jim,
Try to replace,
<jnlp spec="1.0+" codebase="http://localhost:8080/fileviewer" href="index.jnlp">
with
<jnlp spec="1.0+" codebase="$$codebase" href="index.jnlp">
But i was using JNlpdownload servlet to do the task

How to combine two applications with different workspaces in APEX

Hi,
Can anyone help out in merging two applications with different workspaces in APEX 3.2 ?
Thanks in advance,

Hello Satya,
>> I am Satya …
Please take one more step to help us and update your forum handle to something friendlier than user123… Thanks.
>> Can anyone help out in merging two applications with different workspaces in APEX 3.2 ?
This is not a trivial task.
You didn’t mentioned if both workspaces sharing the same APEX instance, or they are on two different instances (machines). I believe the latter is a pre-condition to a success.
First you need to remember that importing an APEX component, like a single page, is possible only to the same application that it was exported from. This is still valid if you have the same workspace on two separate APEX instances – one is an import of the other (which makes it an identical copy). Still, the application ID must be the same, or you’ll get the following error: “This page was exported from a different application or from an application in different workspace. Page cannot be installed in this application.”
You can’t simply manipulating the export file, if the two workspaces are sharing the same APEX instance, as all workspaces on the same instance shares the same APEX metadata files, and you’ll receive a “unique constraint violated” error messages. That means you can’t import one application into the workspace of the other, even if you are using a different application ID.
As far as I can see, the only viable way of doing an application merge is to have two identical workspaces, on two separate APEX instances. The two applications should share the same application ID, although this parameter can be changed in the import file. You should export the page in one application – on the first instance – and import it into the other application – on the second instance.
You should also make sure that the exported page ID doesn’t exist on the target application, otherwise it will be replaced by the new imported page. Also, if the imported page include references to shared components that are not defined on the second application, it might also pose a problem.
As I said, this is not trivial. The benefits are mostly depend on the amount and complexity of the pages you want to merge. If they are not many, and simple, you should consider just re-creating them on the target application. If they are very complex, the merge might fail anyway.

Arie.

Windows critical update blocks Application Express (APEX) with IE6 browser

We recently started having problems with APEX running on an IE6 browser. You get 'page not found' error. It was just 1 user, then 2, then others, on different days. It was weird and we didn't know what was causing it. Our DBA found it quite by accident. He was in APEX with IE6, then did a MS/Windows critical update and now cannot use IE6 with APEX. We are looking at the patches now to try to isolate which one is causing the issue. I was wondering if anyone else is having this issue. It would be Microsoft's latest critical update.
Carolyn

Apex version 3.2.1
DB version 10.2
Web server architecture (?)
Browser: MS Internet Explorer version 6.0.290.5512.xpsp_sp3_gdr.100427-1636
Just trying to access the APEX URL gives 'page not found' error.
We are still on IE6 because a lot of our vendor supplied solutions are still on IE6 so until we get those resolved we have to keep this browser although we are working on a virtualization tool that will help. In the meantime we have told our users they have to switch to Firefox to use their APEX applications and that means constantly switching back and forth between browsers for them. We have identified the MS critical update patch for this but I am looking for a better solution instead of the interim solution of switching browsers.
Thanks,
Carolyn

Can Oracle Application Express (APEX) be integrated with ADF applications?

Hi All,
Oracle Application Express (APEX) works on various supported databases. Can this tool be integrated with ADF for report publishing, in adf some of my result is coming from Business Components , so can these things be related to each other?
Please provide a suitable forum to ask this question if this question doesn't fir in ambit of this forum.
Thanks in advance.

There are a couple of things you can do - a lot depends on what your application needs. Since you ask this in the JDeveloper forum, I'm going to address getting to ApEx from ADF, not to ADF from ApEx - but some of the same possibilities apply.
Easiest thing to do is to jump into the ApEx application with a af:goLink or af:goCommand referencing the needed page's URL. By setting the target, you can control whether it opens in a new window or the same window. I'm not currently using ApEx, but I have a few reports written as PL/SQL Server Pages that I call exactly this way.
You can also open the ApEx pages in an af:inlineFrame - and it will look like it is inside your ADF application - but use inline frames with a little caution - they don't work perfectly in all browsers, notably Mobile Safari.
ApEx can't look inside your ADF BC objects, but of course, if your two applications are using the same database, you can communicate between them within the database. One possibility to look at is Advanced Queuing.
Some ApEx functionality can be executed by executing the underlying PL/SQL procedures - do a search in this forum for how to call PL/SQL from an ADF BC Application Module.

SSO logout issue with APEX

I am trying to resolve the logout URL issue with our APEX application configured as a partner application with SSO. The partner application name is SSO_APEX and the logout URL is defined in partner application as
http://OID_Server:7777/pls/orasso/orasso.wwsso_app_admin.ls_logout where OID_Server is our OID server name.
In the APEX application page, I tried to open the application that was imported from another apex server.
Home>Application Builder>Application 107>Shared Components>Authentication Schemes
SSO_Auth - current is
&INFRA_NAME./pls/orasso/ORASSO.wwsso_app_admin.ls_logout?p_done_url=&SERVER_NAME./pls/htmldb/f?p=&APP_ID.
The logout link is http://INFRA_NAME:7777/pls/orasso/ORASSO.wwsso_app_admin.ls_logout?p_done_url=http://SERVER_NAME/pls/cms/f?p=107 , The application is retrieving the INFRA_NAME and SERVER_NAME values from a database table and they correspond to the OID and 10g application servers respectively.
The logout link should take it to the login page where the user will be prompted to enter login credentials again however it is currently taking to the above logout link page from APEX. It is not changing even though I specified a different logout link in partner application page. Moreover the check box beside SSO_APEX in the logout page is unchecked.
The authentication scheme of application is overriding the partner application configuration. How can I make sure the logout is actually happening? Thanks in advance for any suggestions.
Pavan.

Scott,
I am having the same issue, and have posted on another thread about this same thing. I know that's inappropriate to post the same thing in multiple threads, but I was searching the forum again today, and Pavan described exactly what I'm experiencing.
We have been using SSO for about 4 years or so now, and haven't had logout issues. Our DBA at the time had written his own logout function for SSO where he invalidated the cookie with owa_cookie calls. It's worked until now. We have upgraded our database servers and all URLs referencing those servers are now in a different domain than our OAS server. Now the logic in the logout function is no longer invalidating the cookie for SSO (because it's in a different domain). SSO login and authentication still work, it's just the logout that does not.
I'd like to just alter the logout URL to redirect to the OAS server for logout as you described. But here's what's happening. I press logout link, and it takes me to the OAS Single Sign-Off page where it shows the services it's logging you out of, but it doesn't automatically redirect (just sits there until I press the Return button).
Is that expected (no automatic redirect)?
And as Pavan mentioned, the Partner application name (APEX_SERVERNAME_SSO) doesn't show a checkmark next to it. If I go back to my application, I get right back in without being prompted for SSO (ie, not logging out successfully then).
I know there are a lot of question marks here, but I'm not sure if there's something obvious I am missing or if there's something else I need to fix that I don't know about.
Can you offer any guidance?
Thank you for your time,
Chris
