Remove supporting object in Deinstallation Script

Hello.
I want to define a deinstallation script for my application. It should remove all created database objects and the supporting objects.
I can remove the database objects with SQL statements. But what is the command to remove supporting objects?
Maybe you can give me an example to remove an icon called delete.gif. (I think static items and images are handled in the same way, aren't they?)
Thank you very much.
Stephan

begin
wwv_flow_api.create_or_remove_file(
p_location => 'WORKSPACE',
p_name => 'image.gif',
p_mode => 'REMOVE',
p_type => 'STATIC');
end;

Just update to Pages 5.1 - its dropped the pictures from my Pages files - 'Some features aren't supported - objects in table cells were removed' - how do I get pictures back?

Just update to Pages 5.1 - its dropped the pictures from my old Pages files - 'Some features aren't supported - objects in table cells were removed' - how do I get the pictures back?

Thanks Peter
Can you just walk me through dumping Pages 5 and getting to the Applications/iWork folder - and does this mean that when I see future Pages Upgrades I should block them?
I'm new to Apple so need a step by step
Many thanks

Images in supporting object script

I have noticed in Dene's application* that he has images in the supporting object script. I wanted to do this a while ago** but left images to be installed after the application using the separate import image function. Obviously, I would like to reduce this step to install in one shot. Is this possible or will it be in 3.1?

** Re: Packaged app - image script problem

Solved this by doing some research - did an image export from the application and then replacing the application ID in the script with v('FB_FLOW_ID')
( Re: Installed APP_ID in supporting objects seed data Thanks Scott!)

Supporting Object Install Scripts - populate clob table

All
Before I delve into exactly how I thought I'd ask the forum if anyone had packaged up an install script to populate a table with a clob column?
I have an app that I am finishing up and the one remaining table has a clob column which obviously doesn't make for simple SQL inserts due to the CLOB type.
Thanks in advance
Phil

Hi Vadimon,
Thanks for reporting this, however I am struggling to reproduce the issue.
I created an application with 2 installation scripts (1 without a condition and 1 with a condition set to NEVER), then imported this into a 4.1 instance installing supporting objects. Here, only the 1 without a condition executed, as expected. I then created 2 upgrade scripts (again 1 without a condition and 1 with a condition set to NEVER), then re-imported this to upgrade the application. Again, only the 1 without a condition executed, as expected.
Would you be able to send me an export of an application where this reproduces, or provide the steps you took to reproduce this?
Regards,
Anthony.

How to edit the installation scripts in the supporting objects

I wanted to update one of the installation scripts in the supporting objects. I clicked into that script and use the "script editor" tab. After editing the script, I clicked "Apply Changes" button. It redirected me to the upper level of the page. When I reopen the script, the content of this script is messed up and has the content of another script, not what I have changed. What could happen with it? There is one case that the script was all wiped out!
One general question, how can I easily update the install scripts and reload it without export and import the whole application? or Can I?
Thanks
Fengting

Fengting,
I am not sure what causes this, but I have had the same issue with shared components >> report queries. Sometimes if you have multiple report queries it becomes impossible to edit any of them. If I remember correctly I tried using a different browser and everything seemed to work ok. I was using Firefox when I was having the issue.
Sorry this is not an answer, but I feel your pain!
Cheers,

Xdb_installation_trigger does not support object creation of type SNAPSHOT

hi everyone, i'm using Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit on solaris sparc 5.10
we like to send an email through SSL, and after searching here and there I found out that oracle DB 11g able to go throught the SSL.
since upgrade our DB to 11g would not be an option, so i tried to export XDB of 11g and import it into XDB 10gR2 schema, it was a mess...
then i just reinstall XDB using catnoqm.sql & catqm.sql
and now one of our programmer cant run some script like above

i'm so careless, after checking a fresh installation of the same version DB, i dont found xdb_installation_trigger.

How to remove an object from session with JSF 2.0 + Faceletes

hi all,
I have a facelets page which calls a backing bean of session scope. Now when ever i click on this page i want the existing bean object to be removed from the session . In my existing jsp i have a logic something like this to remove the object from session
<% if (request.getParameter("newid") != null) {
request.getSession().removeAttribute("manageuserscontroller");
%>
Now i have to refactor my jsp to use facelets and i should not be using scriplets anymore . I did try with JSTL but the <c:remove> tag is not supported by facelets.
Can someone help me how can i refactor this code to work for my facelets?
I really appreciate your help in advance
Thank you

r035198x wrote:
Redesign things so that the remove is done in a backing bean method rather than in a view page.Exactly that. I tend to cleanup session variables at the start and at the end of a page flow; generally the end is some sort of save or cancel action being invoked through a button but that is application specific.

Calling Substitution Strings in Supporting Object Installs

So, for lack of a better way of putting it, I have a need to have user input durring the script install part of the supporting objects. I would like to use the Substitution String prompts but can not figure out where it stores the values durring install. It looks as if the system does not commit it to tbl until after the install scripts are done.
I need to create some views that have a different Databaselink based on site location and want the supporting object install scripts to prompt for the name so I can use it in the install process.
Testing on APEX 4.0.1 Oracle 11g
Thanks for any help.

K, found something out. It does store it in a page variable P2103_SS_VALUES and can be called out using v('P2103_SS_VALUES') in the install scripts.

How to remove unused objects from the webcatalog In OBIEE11g

Hi,
I want to delete unused objects from obiee11g catalog, i know in obiee10g it's working fine (i.e: we can do it via manage catalog then delete the unused objects) is there any way to do it automatically like RPD utility --->removing unused objects from Physical layer in RPD
fyi: I don't want to delete manualy. i need somethink like button/link to find unused objects(report,filter,folder..etc) from my obiee11g catalog.
Thanks

Hi,
Checked with Oracle Support team and confirmed below points
--> incorporated into the Current product and consider as BUG it may resolve future release
--> Currently there isnt any automatic method to remove the unused objects like reports, filters,folder etc from catalog.
Treated as Bug

Exporting Apex pages and supporting objects

Hi
I want to export a selected number of pages from my Apex application plus all the supporting objects required for those pages (tables, procedures, etc) to another server.
I've been dabbling and found that I can generate a DDL for the supporting objects, and generate another script for the entire Apex application. Is there any way to do everything in a single script?
Basically I'm looking for the preferred way to export an application (and in particular I would like to be able to export selected parts of the application).

//problem occurs hereI'm not sure that the problem does occur within the
removeCdForTitle() method.
Your main() method calls removeCd() which obtains the title of
the CD to be removed (keyword). But remoceCd() never
calls removeCdForTitle(), so nothing is ever removed.

How do i remove an Object (aliens/ bullets) from my Space Invaders game??

Creating Space Invaders game and im getting confused on removing objects from my game. How do you actually remove an object (i.e bullets and aliens).
I know this isnt the right way to do it, but for the bullets i had an array of the Objects bullets[] and set the x and y coordinates off screen so u cant see then wen they are painted you cant see them, then wen the player fires them, the x and y coordinates change so they come from the players ship till it hits an alien or goes off screen, then i reset the coordinates so they are pasted off screen again. Im relatively new to this so i would appreciate any help. Im going to have to do the same with aliens wen a collision is detected. Is there a way of actually removing an object?
Here is sum code incase you need to see it:
public void checkCollision()
          Rectangle playerRec = new Rectangle(player1.getBoundingBox());
          for(int i=0; i<alienRow; i++)
               for(int j=0; j<alienCol; j++){
                    if(playerRec.intersects(aliens[i][j].getBoundingBox()))
                         collisionDetected();
                    for(int k=0; k<bulletNum; k++){
                         Rectangle bulletRec = new Rectangle(bullets[k].getBoundingBox());
                         if(bulletRec.intersects(aliens[i][j].getBoundingBox()))
                              removeBullet(bullets[k]);
                              collisionDetected();
     public static void collisionDetected()
          System.out.println("COLLISION");
private void removeBullet(Bullets bullet){
          bullet.fired=false;
          bullet.setX(-10);
          bullet.setY(-10);

I was thinking bout that arraylist angle before, but it makes sense now so i think that will work ok. Thx kevin.Not a problem.
Taking the List idea one step further, you could have a parent Object/Interface that all of your game objects extend/implement. Let's call it GameObject.
A GameObject would have a draw(Graphics g) function that you call from your paintComponent( ) method, and for example an act( ) function as well.
You'd have a single List of GameObjects that you add everything in your game into. Now painting is simply a matter of looping over a single List. And in your game logic loop, you could do a similar thing with the act( ) function: your bullet's act( ) would simply move it forward and check for collisions and going off screen. An alien's act( ) function would move it around and maybe shoot a weapon every so often.
Just an idea.

Undable to drop tablespace ORA-01561: failed to remove all objects in the

hi,
i am unable to drop table tablespace how can i do that??
please advise
DROP TABLESPACE tbs_tp2 INCLUDING CONTENTS AND datafiles
ERROR at line 1:
ORA-01561: failed to remove all objects in the tablespace specified
Thanks in advance

Have you tried dropping the objects individually? You can see which objects still belong to this tablespace by using the DBA_SEGMENTS view as shown below:
SELECT OWNER, SEGMENT_NAME, SEGMENT_TYPE, TABLESPACE_NAME
FROM DBA_SEGMENTS
WHERE TABLESPACE_NAME=tbs_tp2;HTH!

Acrobat 9.0 freezes while "Removing unused objects"

I am using Acrobat Pro 9.0 in a Windows 8.1 environment. When I attempt to convert a PDF I created to a Form the program freezes once I click SAVE and "Removing unused objects" appears. I have "repaired" and "reinstalled" the application but the problem persists.

Hi Mike,
I do have some startup items;
EyeTV Helper
AdobeResourcesSynchroni
I Love Stars
GrowlHelperApp
NikePlusUtil
EEvent Manager
EPSON Scanner Monitor
I don't have any haxies on anything.
I made a new user account and tried to replicate the problem but it seems to work fine when logged in as a different user which leads me to think it is a preference in my current user>library
