How to reregister Application after losing APEX

Does anyone know how to re-register an Application with APEX after having to reinstall APEX?
I'm running APEX 3.1.2 on Oracle 11g?
I don't have an export of the Application or a backup of the database.

Dramus,
The correct term that you should use is "re-install", not "re-register".
Having said that, if you do not have an export of the application of a backup of the database, there's little that you can do.
The only think that I can think of is that if you built most of this application in a previous version of APEX (3.0, for instance) and only recently upgraded to 3.1 AND you did not delete the FLOWS_030000 schema. If you meet all of those criteria, then you should be able to get it back; otherwise, I'm afraid there's little you can do but start over.
Thanks,

How to relaunch application after download?

Hi
I have lanuched an webstart application form the internet and successfully run the application on my desktop, but once I close the app it is gone. I have no desktop shortcut to get to it again. How can I access my downloaded apps after download? Remember I have no desktop shortcuts to webstart or the app.
Thankx

Follow Up;
I have used Andrew's advice to install shortcuts, and they work fine. (desktop, start menu, icon image and running)
The impression I got from jnlp documentation was that I could have this done automatically, with out the user having to repeat such steps.
Is this possible?
here is my jnlp file;

How to import updated version of APEX app without losing saved IR's?

Oracle XE 11.2
Apex 4.1
Linux Red Hat 5.4
============
Does anyone have suggestions on how to import updated version of APEX app without losing saved IR's?
Also, I want to maintain app id from update to update (from revision to revision). In fact, I think that that is required in order to keep the saved IR's.
The only process I have found that seems to "work" (i.e. loads new revision of app over old revision of app) is the following (via SQL*Plus):
declare
l_workspace_id number;
begin
select workspace_id into l_workspace_id
from apex_workspaces
where workspace = 'MYWORKSPACE';
apex_application_install.set_application_id(400);
apex_application_install.set_workspace_id(l_workspace_id);
apex_application_install.generate_offset;
apex_application_install.set_schema('MYSCHEMA' );
apex_application_install.set_application_alias( 'MYSCHEMA_ALIAS' );
end;
@new_version_of_app.sql;
but I do not have any saved reports in this app. Will this process keep the saved IR's from the previous version of the app 'intact'?
Thanks.

Hi,
I cope with the same issue.
But I've several prod instances and many applications on each of these... and SIR saved by many users.
Of course each prod application have its own ID, distinct from the dev application ID.
Is there really not any kind of solution in my case (apart from release the dev app on the dev workspace ; export 50 apps from it and import those 50 times, maybe more in the futur) ?
I'd be a pity if not, I think there must be a lot of us working in that configuration.
Thanks !

I am attempting to upgrade from Adobe Premier Elements 9 to Adobe Premier Elements 13 after using 13's trial version for a few weeks. I am unable to find where and how to do this without losing the project I have been working on. Please help?

Vere Clarke
Premiere Elements 9.0/9.0.1 and Premiere Elements 13 are standalone products.
So, you can have both on the same computer, but only open one for your work.
The classical recommendation is to finish a project in the version in which it was created since there
is no guarantee that a project from an earlier version will open in the later version. Probably will, but
no guarantees. And, when you do explore this, do it from a copy of the earlier version project. Once you
take the earlier version project into a later version one, you cannot go back to edit the later version edited
project in the earlier version program.
If you have both versions (9 and 13) on the same computer and you have not moved, deleted, renamed any of the version 9's files/folders,
right click the saved closed Premiere Elements 9.0/9.0.1 project file, select Open With, and then Adobe Premiere Elements 13.
(Your 9.0/9.0.1 saved closed project file should be found in Libraries/Documents/Adobe/Premiere Elements/9.0.)
Please review and consider. If any questions or need clarification, please do not hesitate to let me know.
Thank you.

How do the application servers connect the new database after failing over from primary DB to standby DB

How do the application servers connect the new database after failing over from primary DB to standby DB?
We have setup a DR environment with a standalone Primary server and a standalone Physical Standby server on RHEL Linux 6.4. Now our application team would like to know:
When the primary DB server is crashed, the standy DB server will takeover the role of primary DB through the DataGuard fast failover. As the applications are connected by the primary DB IP before,currently the physical DB is used as a different IP or listener. If this is happened, they need to stop their application servers and re-configure their connection so the they coonect the new DB server, they cannot tolerate these workaround.
Whether does oracle have the better solution for this so that the application can automatically know the role's transition and change to the new IP without re-confige any connection and shutdown their application?
Oracle support provides us the answer as following:
==================================================================
Applications connected to a primary database can transparently failover to the new primary database upon an Oracle Data Guard role transition. Integration with Fast Application Notification (FAN) provides fast failover for integrated clients.
After a failover, the broker publishes Fast Application Notification (FAN) events. These FAN events can be used in the following ways:
Applications can use FAN without programmatic changes if they use one of these Oracle integrated database clients: Oracle Database JDBC, Oracle Database Oracle Call Interface (OCI), and Oracle Data Provider for .NET ( ODP.NET). These clients can be configured for Fast Connection Failover (FCF) to automatically connect to a new primary database after a failover.
JAVA applications can use FAN programmatically by using the JDBC FAN application programming interface to subscribe to FAN events and to execute event handling actions upon the receipt of an event.
FAN server-side callouts can be configured on the database tier.
FAN events are published using Oracle Notification Services (ONS) and Oracle Streams Advanced Queuing (AQ).
=======================================================================================
Who has the experience and the related documentation or other solutions? we don't have the concept of about FAN.
Thank very much in advance.

Hi mesbeg,

For example, there is an application JBOSS server connecting the DB, we just added another datasource and put the standby IP into the configuration file except adding a service on DB side like this following:

If the failover is occurred, the JBOSS will automatically be pointed to the standby DB. Additional actions are not needed.

How can I reopen applications after hide

How can I reopen applications after hiding it using Command+H?
Usually we can find applications that are running in the dashboard after minimizing it, but I cannot find them after hide.

Well, then, it is possible to set an option in the Dock to show hidden applications as transparent icons, but you need to use a utility such as iTweakx or MacPilot to enable it. If you have a normal Dock, of course all running applications have a little oval "light" under them.
True "background" applications are always invisible.
You could use the option of minimizing an application to the Dock so that it will always appear on the right side of the Dock. I use the option of double-clicking on a window's titlebar to hide the window/app onto the right side of the Dock.

How I can closed all open application after update to iOS 7.0.2.0?? Before this v iOS7 we was can closed any application's open :(

How I can closed all open application after update to iOS 7.0.2.0?? Before this v iOS7 we was can closed any application's open :(

There's no good way to do it. But you don't need to. iOS 7 automatically handles whether an application takes up memory or has files open. There's no real advantage to you ever closing an application yourself.
If you are having problems with a particular app, please describe them.

When you have a problem you'll get a faster, more effective response by including as much relevant information as possible upfront. This should include:
<li>Full APEX version
<li>Full DB/version/edition/host OS
<li>Web server architecture (EPG, OHS or APEX listener/host OS)
<li>Browser(s) and version(s) used
<li>Theme
<li>Template(s)
<li>Region/item type(s) (making particular distinction as to whether a "report" is a standard report, an interactive report, or in fact an "updateable report" (i.e. a tabular form)
With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.
I have an issue here. As per the requirements I need to change the application title in Apex while

This change has to be done Dynamically. Without Entering it Manually.Also clarify what you mean by "instance". An "APEX instance" refers to the APEX installation in a database. The "APEX instance" does not have a specific name property, and would therefore usually be referred to using the database name. Or do you mean the APEX workspace containing the application?

Hi katana,
Go into your Finder under Applications:
Click on iPhoto to open it - it will go to your Dock. Click and hold down on the icon on the Dock, and you will see "Options". Click on that, and then select "Keep in Dock". Do the same with PhotoBooth. You should be all set!

How to update Back end applications after successful message transport

Hi All,
Currently we have a SOA composite that reads failed messages(Msg type 3) from B2B JMS message queue and updates our business tables of any b2b failures. However we are not sure how to handle successful B2B message transport scenarios.
How back end applications(SOA composite) know b2b messages are handled successfully by B2B? How do we capture this successful scenarios? We don't have ack enabled.
Thanks,
Kathar

However is there any push mechanism from b2b for this scenario.Option#1-
B2B pushes messages details to BAM AQ (B2B_BAM_QUEUE in SOAINFRA schema) from where BAM picks up the details and uploads in it's data objects. If you are not using BAM then you may receive messages from this AQ. This is again a batch job and it is controlled by below two parameters -
Enable BAM
BAM Polling Interval
http://docs.oracle.com/cd/E23943_01/user.1111/e10229/bb_config.htm#CEGEADFJ
Option#2 -
Write your own DB job which pulls details from B2B_INSTANCEMESSAGE view and pushes it for you at desired location.
Only batch job is suitable for this scenario because B2B uses different set of intermediate states while message processing whereas you are only interested in one terminal state (MSG_COMPLETE)

How Does an Application connect to the DB after authentication

We working on a prototype to implement the OID
and achieve Single Sign On.
We have an OID installed,
The wallet manager installed.
The Wallet Client Installed.
We have an DN entry created into the OID.
We then login into the Wallet client.
How do we connect to the database..?
Or how will an application connect into the database.
We have the users created into the database as:
"create user <username> identified globally as <Complete DN for the user>;"
Is it through Net8 LDAP Native Naming Adapter.
Where can I find some more info on this LDAP Native Naming Adapter.
Regards,
Puneet

Hello Puneet:
Are you trying to acheive Enterprise user authentication useing OID? If so you should visit our Advanced Security web page
located at:
http://otn.oracle.com/deploy/security/aso/content.html
There are a few technical whitepapers you should read there. Namely "Enterprise user security" and
"Oracle Advanced Security: Security and Directory Integration"

Deploying an Application to a APEX 3.1.1 Runtime Environment

Hello Everyone,
I'm trying to work out how to deploy an application from a development to runtime environment but am facing a few issues / uncertainty and would appreciate any input/help on this. To begin with here is my environment:
- Apex 3.1.1
- Two Oracle 9i (9.2.0.8) instances running on different hosts (development environment on host AA and runtime environment on host BB)
- Using the Oracle 9i HTTP Server with mod_plsql (on both hosts)
- DEVLWS workspace +(on development env)+
- DEVSCHEMA schema +(on development env)+
- USER01 - non-developer & non-admin user +(on development env)+
- DEV01 - developer and admin user +(on development env)+
I'm performing this test deployment with the downloaded application Timesheets from apex.oracle.com with the application ID of 111 (when imported into my development environment).
Situation:_
I have no issues on the development environment. I can import the Timesheet app into it and run it using either the USER01 or DEV01 ID as it was imported into the DEVSCHEMA schema. However, when I try to deploy over to my runtime environment, here is where things gets sketchy on this.
1) In order to get this application (Timesheets) to run properly on my runtime environment, I've to perform a Oracle9i EXP of my DEVSCHEMA objects and import this into my runtime environment using the IMP utility to get the proper workspace and associated objects over,
--> I tried exporting the workspace on the development env but even after running it on the runtime env, I was not able to get the application to run (missing workspace schema, users etc).
2) From my development environment, I export the Timesheet app with supporting objects option and on the runtime environment, I use SQL*Plus as such:
SQL> alter session set current_schema=FLOWS_030100;
SQL> @f111.sql
Once the script completes, I use the http://hostBB:7776/pls/apex/f?p=111.1 url and was able to get in to the application, however I found things like the images are missing and I've to manually export these again from the development env and run the generated SQL script file on my runtime env.
Is there a better (and documented step by step) way of doing this kind of deployment? The Apex User Guides talks about creating a packaged application but I didn't see this as a way to deploy specifically into a runtime environment as I followed it and still had missing images. When I did the export of the Timesheet application, I used the DEV01 id and made sure I selected the 'with supporting objects' option but yet I've to do most of the steps manually (i.e. build the schema, tablespace, application tables via exp/imp) and again the images were not included.
Is there a document / note available that discusses this in better detail (deploy from Development env to Runtime env) so that I can do cut down the manual steps and making sure that my developers can effectively deploy our apps with minimal fuss and headaches? Appreciate any input.

...I've to perform a Oracle9i EXP of my DEVSCHEMA objects and import this into my runtime environment using the IMP utility to get the proper workspace and associated objects over,...
EXP/IMP will not do workspaces. You can use the Application Express apex_admin application to export a workspace to a file. Then, in a runtime environment, you can install that workspace file using SQL*Plus. This way of
creating the workspace also ensures that it will have the same workspace ID as it did in the original database, making possible the installation of exported applications from application export files from the original
workspace into the new workspace having the same workspace ID and also where the installed applications are to have their original application IDs.
... and still had missing images. When I did the export of the Timesheet application, I used the DEV01 id and made sure I selected the 'with supporting objects' option but yet I've to do most of the steps manually (i.e. build the schema, tablespace, application tables via exp/imp) and again the images were not included.
Images aren't part of application exports. Exporting the images to a file and then installing them using that file and SQL*Plus is the way to do it.
As Patrick mentioned, running the application export file in SQL*Plus doesn't run the supporting objects script. It creates the script in the datbase. But in a runtime environment you can't run the script because the runtime environment lacks the Application Builder.
SQL> alter session set current_schema=FLOWS_030100;
SQL> @f111.sql
You can install applications by connecting as a less privileged schema. Any schema assigned to the workspace into which the application is to be installed will do. To install workspace export files (or applications), you can also use a schema that has been granted the role APEX_ADMINISTRATOR_ROLE.

How to change an after login page?

Does anyone knows how to change an after login page from a default page 1 to, let's say page 200?

Jessica,
The URL to run your application is http://apex.oracle.com/pls/otn/f?p=23533.
If you use this, page 3 is the first page shown after login.
Using the URL you gave runs the Application Builder, not your application. If you use the Builder's Run Application icon to run your application, the page in your application that you are requesting is page 1 (or whatever is in the application's Home URL attribute). But running your application this way is something you do in a development environment only
Your basic question has to do with how end users would get to a particular after-login page. End users do not have access to the Application Builder.

How to upgrade db10g xe with APEX 2.1 to APEX 3.2

Hello
I have been using oracle db10g xe to learn oracle as i am new to it which according to oracle contains APEX 2.1. according to oracle that syas:
Oracle Database 10g Express Edition (Oracle Database XE) includes Oracle Application Express (Oracle APEX) release 2.1. With the release of Oracle Application Express 3.2, you can now upgrade the Application Express within your Oracle Database XE.
(The URL for above statement is::: http://www.oracle.com/technology/products/database/application_express/html/3.2_and_xe.html)
As a part of upgrade from APEX 2.1 to 3.2 one of the requirement is:
Choosing an HTTP Server
In order to run, Oracle Application Express **must** have access to either the embedded PL/SQL gateway or Oracle HTTP Server and mod_plsql.
(The URL for above stataement is::: http://download.oracle.com/docs/cd/E10513_01/doc/install.310/e10496/otn_install.htm#CBHBDAIF)
As it mentioned in the url above the embedded PL/SQL gateway only available with Oracle Database 11g or higher but I have db 10g xe and as it mentioned in oracle web site. (first url) the db 10g xe can be upgraded to APEX 3.2.
That leave me with Oracle HTTP Server and mod_plsql as a MUST have component but nowhere in the documentation mentions where and how to get it and install it in oracle db 10g xe which i've been using.
Please help me to resolve this issue because without it i can't upgrade from APEX 2.1 (within db 10g xe) to APEX 3.2.
it's been two days that i have been reading all the docs but it doesn't says where to get Oracle HTTP Server and mod_plsql with installation guide.
Please let me know how can i upgrade to new APEX 3.2 as i don't want to lose db 10g xe and start all over with 11g.
Please put URL or your finding about upgrading from APEX 2.1 to APEX 3.2 here.
Thank you for your help.
Shawn

Hi
Sure. i will.
the installation instruction at the link i posted before is missing two major steps where you must first create two tablespace as:
tablespace_apex
tablespace_files
The instruction i put its url previously perhaps is very high level but the best step-by-step instruction i did and worked charmingly right after installation can be found at:
http://blogs.oracle.com/SanthoshK/2008/09/oracle_xe_apex_3x_installation.html
Please do me a favor and take a look at my problem with APEX 3.2 developer guide\tutorial.
I posted a thread under Application Express link in forums's home. (3 link from top).
my thread can be found at >>> PLEASE SOMEONE TAKE LOOK AT THIS! APEX 3.2 - error in OEHR build in sample.
Please help me out with this one as i am doing exercises in dev guide and thought those exercises are error-free.
the exercise is at >>>> http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28551/build_app.htm
under: Modifying the Departments Report
as soon as i copy past the code to Source box of the Department it gives me error pasted in my thread.
even if i copy past the code in SQL Workshop it doesn't work. it says: table can't be parsed.
even tonight i proceeded further and was doing the second exercise in same url for:
Editing the Employees Report.
I copy past the given code to Source box but this time the report doesn't show new result. seems like a change doesn't take effect even i logout and in back.
even in SQL Workshop it works but in running the page 3. employees it doesn't show changes at all.
sorry for not being short but since i'm new to Oracle i don't want to skip information.
thanks a lot.
