Migration HTMLDB 1.6 to Application Express 2.0

Hi,
we have a HTMLDB 1.6 on a Database 9i (9.2.0.6).
Can we migrate on Application Express 2.0?
Are there any known problems? What do we have to do?
Thanks in advance
Ulrike

Yes, this is 100% possible and supported. All you will need to do is install ApEx 2.0 and make some small changes to your HTTP server.
The detailed steps required and much more is documented in the ApEx 2.0 User Manuals.
Thanks,

PL/SQL Counter for HTMLDB - Application Express - Survey Counter

I wonder if somebody could help me to clarify the HowTo on this Survey.
Based on:
http://www.oracle.com/technology/products/database/application_express/index.html
http://www.oracle.com/technology/oramag/oracle/06-mar/o26browser.html
I follow up however that is not exactly what I like to see in my Survey. I like to make something more elegant and flexible.
On this example he put 10 questions/ page. I like to use 1 Question / Page.
And I like to extend to more than 10 pages. for example 20.
My question to the forums is:
If I create an application with Only 3 pages [ Welcome, Survey, End ]
And the main page for the Survey is the second page.
How would programatically be the logic to:
Start the Welcome page => Setup variable counter = 1
Then using sessions with a button click on Start Survey.
Survey Page check for the existence of counter variable if exist retrieve the Question from the Questions table and the properly Answer will be recorded.
This answer could include comments, and the Rating could be an LOV.
After the Question 1 is asnwered then the Next Button on the Page 2 Call the same page 2. If the Questions is the max number of questions [20] then go to the End or Summary Page. if not just increase the counter variable then retrieve the next question.
Am I asking to much ???. I'm just starting on PL/SQL and HTMLDB I'm not sure how to manipulate those variables. I've been trying but I'm stuck.
Thanks in Advance for your Help.

Creating HTMLDB DAD for Application Express

Good Morning
I have http server running on port 7777 with PLSQL _mod. I can add DAD's using
the Mod plsql configuration menu
and get data back from procedures in my schema.
I have downloaded and installed Application Express ,its all gone into
FLOWS_02000 schema. It all loaded ok.
I don't seem to have a htmldb DAD set up though.
I tried to configure one using the Mod plsql configuration menu with out success
Is there an application that creates the necessary configuration to get HTMLDB
and http server working together.
Thanks
David Hills

David,

Migrating from HTML DB 1.6 to Application Express 3.1.2

Good morning,
After recently discovering APEX and spending some time with the Oracle provided instance, the shop I work with have decided to proceed and give it a shot with our Oracle instance.
We're running 10g and our DBA setup HTMLDB from the companion CD for me. It's up and running just fine but after playing with APEX 3.1.2, going back to HTMLDB 1.6 has me noticing a lot of things that I miss just from the short time I spent with APEX.
How much is involved in the process of upgrading from HTMLDB to APEX and are there any documents aside from the APEX Install Guides that provide the steps or is it pretty straight forward? Our DBA is extremely busy and I don't want to add too much of a burden but before me and a few other developers start migrating some old Forms 6i applications, I would prefer to be up to date with the latest and greatest.
Thanks!

Hello,
>> Good morning,
Well, that’s depend on your location in the world. For some of us it’s the end of the day :)
>> How much is involved in the process of upgrading from HTMLDB to APEX
All you need to do is to download the APEX 3.1.2 full version distribution file, and run the installation script. The upgrade process will done automatically, by the installation script.
>> are there any documents aside from the APEX Install Guides that provide the steps or is it pretty straight forward
It’s very straightforward, especially in your case, where as I understand the history is very small. I find the APEX installation documentation to be very good and very clear. All you have to do is carefully follow the pre-installations and post-installation tasks (there are some important configuration changes you’ll need to make between 1.6 and 3.1.2), and you (and your DBA) will be just fine.
Regards,
Arie.

Version Control for Application Express

Hi all,
We are using Application Express (HTML-DB) 2.0 with Oracle 10g Release 2. We have developed a number of pages within our application (basically sales reporting). We are starting to get ready move these pages to a test and production environment.
Before we move to a production environment we need to implement a version control and migration (development -> test -> production) system. I have read various posts about importing and exporting pages and applications that have been very informational. However, I am still not clear on certain areas, any help/information on the below questions/comments would be helpful.
1.     How are other people implementing version control? For some of our other environments (for example, PeopleSoft-SQR) we use Visual Source Safe. Can we use this along with Application Express or is there a way to keep track of versions within Application Express it self?
2.     I see you can view a pages history at Home>Application Builder>Application 107>Page Definition>History. Is there a way to view the differences between the pages or to revert back to an older page?
3.     I know you can export a single page but that leaves shared components behind that might leave the complex page in a non-working state if imported and installed in the production application. Is there a way export and import shared components, for example LOVs?
These are a few of the questions I havebut I thought it would be a good place to start.
Here are a couple of links that have given me some information related to the topic.

Version Control
How do people version control HTML DB applications?
I would be interested in hearing your thoughts and ideas on this topic.
Thanks,
Stuff

Stuff - this is also something we've been grappling with.
Did you see the excellent tip about using Web server (or PL/SQL) redirects to point to the current app? The idea is that you copy the current prod app, work on the copy and then update the redirect to point to the new app when it's released and make the old app unavailable.
This is quite brilliant in its simplicity, and has the added benefit of leaving the old app intact for bug fixes and re-releases, (or even rollback) if necessary. However, the problem with it, and the reason it's no good for our purposes, is because it sits on top of the same schema, so if the version control applies to objects in the database (i.e. the schema itself or packages etc.), then you're snookered (as far as I understand it anyway).
In a previous project, our suppliers used VSS and versioned code at the app and function/procedure/package level - I'd love to know if anyone has a robust scheme for versioning at page level.
I suspect History is an audit trail rather than versioning - I can't imagine that all the objects in all their respective states are being persisted for anything other than 'undo' purposes.
Versioning at page level seems to be problematic but it can be done, provided that the shared components are sufficiently consistent. The trick is to edit the security group ID, but the usual caveats apply.
What seems problematic to us is how to create a build out of components at different versions, like you might in a conventionally-packaged exe. I think we might end up checking in (or just saving in the file system) consistent versions at app and package level (having developed and tested in a separate schema or instance), and doing an overwrite of the prod app plus running a DDL script for package/function/procedure updates with schema deltas and other things like image uploads applied manually at cutover.
I suspect that once I delve a bit deeper into where all these objects are stored, there will be more potential for scripting, but I'm not entirely confident that this will, reliably, give us entirely what we had in Pre-Prod. Another problem I've found with this approach is that packages don't get consistently replaced.
It may simply be that we're applying waterfall concepts to what is really a RAD tool, but in any case this is my first Web-enabled development so I've been at sea with everything from design methodology to version control.
Like you, I would be really interested to hear of other suggestions.
Regards,
John.

Change over from Apex to Application Express

When I connect to Oracle 10G XE I use the following URL:
http://127.0.0.1:8087/apex/f?p=4550:11:73807998927860::NO:::
Now I have downlaoded Oracle Application Express. How do I use it with my existing data on 10G XE?
Do I need to have 11g?
Thanks
Edited by: user506392 on Sep 15, 2009 2:42 PM

Perhaps the following will help:
Oracle has a family of Database products. These are released every few years. The last few releases are
Oracle 7; Oracle8; Oracle8i Database; Oracle9i Database; Oracle Database 10g; Oracle Database 10g Release 2; Oracle Database 11g; Oracle Database 11g Release 2
For Oracle Database 10g Release 2, the family consists of a number of Editions which represent groups of features. In the follow list of editions, each successive one to the right includes the features of the one to the left:
Express Edition; Standard Edition One; Standard Edition; Enterprise Edition; Personal Edition
SO you can see, Express Edition (known as XE) has the fewest features. Each feature, when released, has a version. Some of these features included with Express Edition are
- SQL language version 10.2.0.1
- Oracle Networking 10.2.0.1
- SQL*Plus 10.2.0.1
- Oracle XDB 10.2.0.2
- Application Express 2.2 (known in the community as HTMLDB, ApEx or Apex)
The Apex feature gives us several capabilities: a web application development tool; an Oracle database access tool; (with XDB) a web application run time engine a bit like a mini Apache server. All of these capabilities (and more) are available using a browser.
Apex 2.2 was a customized version of Apex designed for Express Edition. It includes several applications that can be used to administer an Oracle database.
Oracle designed Apex to be easily upgraded. Since "Oracle Database 10g Release 2 Express Edition" (Oracle 10g XE for short) Oracle has provided several new versions, any of which can run in XE. However, the special applications used to manage Oracle DB are not available.
By looking on the page I previously mentioned, you can get an idea of the new capabilities available in the newest version of Apex - version 3.2. It's up to you to decide whether it's worth losing the DB Admin capabilities in order to get those new Apex developer capabilities.
In any case, you shoudl have enough background now to at least look at, and start to understand, the Apex tutorial and some of the other info on the Apex page, as well as the XE documentation page at http://www.oracle.com/pls/xe102/homepage

Application Express Vs developer suite 10g

Hello
I am a beginner and I am confused which application package I have to use to build
my application consisting of forms and reports.
Can someone please highlight the difference in applications created using
application express and developer suite 10g.Their advantages and which one is
preferred with oracle 11g database as backend and its support with OS windows vista.
Please help us.Since we are planning to upgrade our old software developed
using oracle 8i and developer6.0
Thanks in advance

Thanks for your suggestions.
Please suggest us once again how to proceed in our environment.
Actually we have developed an in-house erp package consisting
of different modules for production, finance, inventory .There
are many forms with many fields and customised reports and plenty of data entry.
As per your suggestion we can use Developer suite 10g by doing
one is to one migration with some modifications as required by developer suite
and moreover it is used only locally in intranet.This also needs a browser.
(this will be faster compared to APX since we have to redo all the forms
and reports from the beginning which will take time.).
Our doubt is, can we make our application (developed using developer suite)
web enabled later on without going for APX so that we can access our application
from customer or remote site through internet.
In that case what will be the requirement and how do we go about in making
our application web enabled.
Thanks once again for your valuable suggestions.

Application Express 3.0.1 Upgrade

I am running Application Express 2.0.2.00.49 and the backend is Oracle 10.2.0.1.0
on Linux 32bit and 64bit 9.3 Susie Servers. I want to upgrade to the new 3.0.1 Application Express and wonder what steps or tricks there might be waiting for me when I do this.
Thanks,
Tim

Tim,
Hopefully, there shouldn't be any tricks whatsoever. It should be as simple as a normal installation of Application Express, and your existing data (e.g., workspaces, applications) will be migrated forward.
Like with any type of upgrade, if you have the opportunity, it's prudent to take a backup beforehand.

Oracle 11g XE Application Express - Retrieve or reset password

I cannot remember my password to access an existing database in Application Express. I tried entering my password 3 times, but the system does not provide a status other than 'Invalid Login Credentials'. I am going to assume that 3 times is limit before you have to reset the password or from what I see reinstall. When selecting reset, the system asks for an email address that was never established in the system. How can I reset my password without uninstalling and reinstalling Oracle 11g XE?
Any help will be greatly appreciated.

Hi,
You can login with ADMIN user to INTERNAL workspace and manage all workspace users and change passwords.

What has happened to Application Express Studio?

Application Express Studio (http://htmldb.oracle.com/studio) appears to be dead. The most recent posting to it was about 13-DEC-05. Why? There is no link to it from the OTN Application Express web page. Maybe that is one reason.
Mike

Well, I think the problem is that very few people ever actually contributed to it (myself included). When you see something like -
"Time Tracking System (Added 1.7 years ago)"
In the "Most Recent" section, then there is little enthusiasm for people to post something of their own. It is a strange thing, but if there was 1000 applications, themes etc there then 'someone' might be more tempted to upload something of their own, however that means that 999 people before them would have needed to feel the same way.
It's exactly the same with the Unofficial APEX Wiki (http://wiki.shellprompt.net/bin/view/Apex/WebHome) that I host, it lives and dies on contributions from people. If nobody contributes then it ceases to be useful, if it ceases to be useful then people won't contribute...it's a vicious circle.
But, as I said, I'm as guilty of not contributing to the Studio as anyone else.
John.

Importing components to Application Express

When trying to import a component export into Application Express with same app Id and workspace I have problems when I get to the report layouts and report queries.
I get this for some, not all of the report layouts:
Component Export: REPORT LAYOUT 30423319886223781
...report layouts
WWV_FLOW_API.ERR_REPORT_LAYOUT_CREATE ORA-00001: unique constraint
(APEX_030200.WWV_FLOW_REPORT_LAYOUTS_IDX2) violated
but the import continues until it gets to the report queries, I get through 5 and then this:
Component Export: SHARED QUERY 25478002913036435
...shared queries
declare
ERROR at line 1:
ORA-00001: unique constraint (APEX_030200.WWV_FLOW_STORED_QUERIES_UK1) violated
ORA-06512: at "APEX_030200.WWV_FLOW_API", line 6261
ORA-06512: at line 32
then it stops and quits...
Why am I getting this on only certain report layouts and queries??

Hi,
I think you are posting to wrong forum. Virtualization Discussion Forum is here.
Oracle VM Server for x86
Anyway,
There is by default obe workspace. User and password for that workspace is obe
If you need login to APEX administration, then use apxchpwd.sql from oracle user home folder to reset INTERNAL workspace ADMIN user password.

Basic problem in displaying the pdf and images in Application express

Hi,
I have oracle 10g and application express.
I have already stored the images and pdfs using PLSQL in table with following columns
TableA(vessel number, cruise number, image blob, pdf blob)
now for every vessel, cruise combination there is a particular image and pdf.
so in my htmldb page.
I have created 2 select list for vessel and cruise respectively.
now on selecting these lists i want to diaplay their corresponding image and pdf.
How can i do this? I just somehow miss the basic knowledge of how to do this.
Should i create a html region or a report region for the image and pdf.
under what region the image and pdf goes. and on sleecting the vessel, cruise can i show hyperlinks and upon selecting the hyperlinks a image and pdf opens in a new window.
or can i create 2 regions and display the image and pdf right in the region itself.
Can someone please guid eme please.
Thanks,
Philip.

Hi Philip.
I suggest switching to the Application Express forum.
Pretty sure it'll be easier for you to find the answers over there

How to Create application express items like text box dynamically

Hi all,
I have a requirement in that i have to create a template like the one in Application express for creating the region and items.
The main requirement is to reduce the amount of time spend in creating the items on htmldb page..
So we are planning of creating a template where the developer at one shot will be able to define all the items used in the the page..So this reduce the amount of time taken in creating and defining each and every item .
Developer use this template which conisist of some 100 text box which act as label for the item which we want to create on the page and there will be check box which show all the item available in htmldb like textbox, check box, select list etc. So developer will check the item he/she want to create and and set properties of it .So this is the single process for creating all the template on the page.
Ones the template is submitted it will create the items on the page ...in a single click..
Please do reply me with ur comments
Thanks

Hi,
I wanted to do similar thing as well. I wanted to add a text field when user clicks a link or button. I was thinking about java script, but not sure how to add the text field items from outside the wizrdy things in APEX!! Possibly using the htmldb_item api, but have not worked out how yet.

Database security with PUBLIC EXECUTE privileges for Application Express

I recently tried installing APEX into an existing database containing a data warehouse. Security on this database is quite controlled and PUBLIC EXECUTE to SYS owned objects had been removed. Ie there was no PUBLIC EXECUTE on:
DBMS_LOB
UTL_HTTP
UTL_FILE
UTL_SMTP
UTL_RAW.
When I tried to install APEX, I got all kinds of errors and logged a TAR. The analyst told me to grant execute to public to the above SYS owned objects. This contradicts the "Policies" in 10G Grid control and the Metalink Notes 131752.1 &
Note:247093.1.
Can these execute privileges be changed to another user in the htmlDB
application such as FLOWS_FILES? Or HTMLDB_PUBLIC_USER? What is the security reccomendations for Oracle Application Express? Calling any product managers out there....

Developers/users have started clicking around and are now getting errors. There is a function called CUSTOM_AUTH and one called CUSTOM_HASH which do not compile. They have complain about not seeing UTL_RAW so had been relying on PUBLIC synonyms. here's the 1 function:
create or replace function custom_hash (p_username in varchar2, p_password in varchar2)
                         return varchar2
                         is
                         l_password varchar2(4000);
                         l_salt varchar2(4000) := '2ZVKZMILYMGVFRFXOZIVZ72RJNJY8V';
                         begin
                         -- This function should be wrapped, as the hash algorhythm is exposed here.
                         -- You can change the value of l_salt or the method of which to call the
                         -- DBMS_OBFUSCATOIN toolkit, but you much reset all of your passwords
                         -- if you choose to do this.
                         l_password := utl_raw.cast_to_raw(dbms_obfuscation_toolkit.md5
                         (input_string => p_password || substr(l_salt,10,13) || p_username ||
                         substr(l_salt, 4,10)));
                         return l_password;
