Application Express :: How To Access User Information
Jan 2, 2013
I am new to Oracle APEX, and have a few questions regarding the user information.
I've created a new workspace on my local APEX installation, created some users in the workspace, and divided them into roles as "Managers" and "Employees". I am the only Dev and Admin of the workspace, and the users (Managers and Employees) I have created are viewers.
I'd like to create database tables in the workspace where some field would refer to the user ID of the created user as a foreign key, and their role. Similarly, I'd like to create pages where a particular region is displayed only if the logged in user is a "Manager". How can I access the user data and the role data using SQL?
I see following tables in my workspace, so which table contains the user information:
APEX$_ACL
APEX$_WS_FILES
APEX$_WS_HISTORY
APEX$_WS_LINKS
APEX$_WS_NOTES
[Code]....

When I invoke SOAP Web-Service using APEX_WEB_SERVICE.MAKE_REQUEST, then I'm able to get response from web-service. However all German character are replaced by JUNK data. However data is coming fine when I test web-services using SOAP UI.
I tried to invoke web-service using UTL_HTTP. However when I use UTL_HTTP, then I'm getting following error.
ORA-24247: network access denied by access control list
<li> Why German characters are replaced by Junk data while invoking web-service from APEX, while it's working fine from SOAP UI
<li> When I can access web-service successfully using APEX_WEB_SERVICE, then why it's throwing ORA-24247 error when I call using UTL_HTTP?

I just installed Apex and want to create an application that accesses data in a non-Apex schema. However, when I create an application I can't see objects in other schemas. I tried specifying the schema and tablename (e.g. apps.gl_je_headers) but that didn't work. I can only see objects in the APEX schema. How do I reference other schemas when I create an application?

I have installed APEX on my local machine, created a workspace, and added a few users with roles.
I am creating an application, similar to a Library app, where I have a table that stores Books information (BOOK_ID, BOOK_NAME, etc). I'd like to create another table BOOK_USER with two columns, BOOK_ID and USER_ID. BOOK_ID would refer to the BOOKS table, and I want USER_ID to refer to the table that stores user details of the workspace that I am using. The data entry would happen from a page that has two LOVs, one for book name (using BOOK_ID as the value) and another for user name (USER_ID, or whatever field APEX uses to store user's ID). Can I do that in APEX? I've found ways to access and authenticate a user for a page, but how to get data of all users in the workspace? In other words, how to get all usernames in a LOV?

Apex 4.1.1
Oracle 11g
I have two applications both in the same workspace. I want to log into one of them, but then have a link to a page in the second application, without having to enter a login to the second application.
Trying to follow the following from a while back, but cannot make it work in apex 4.1.1. Is it possible to access two application with one login? Both application are using the same ldap authentication.
I have both applications using the same get cookie process on page 101
{
declare
v varchar2(255) := null;
c owa_cookie.cookie;
begin
c := owa_cookie.get('LOGIN_USERNAME_COOKIE');
:P101_USERNAME := c.vals(1);
exception when others then null;
end; }
The link I use to the second application is a javascript pop window for displaying the second application and call it with the java pop up url
{
javascript:popUp('f?p=366:1:&SESSION.:::::')
}
However, it still asks me for the login to the the second application. I found other conversations that said to fill in the cookie name in the Session Cookie Attributes in Security, Authentication of the second application and entered the cookie name LOGIN_USERNAME_COOKIE here. However I still get the second application login screen now with a bunch of numbers in the username field.
What am I missing to get this to work without having to login again for the second application?

I have a number of pages containing charts and gantts. I want the user to be able to filter the data shown in these various charts. More than that, I want the user's filters to persist between pages. So, if they select "Key project = 'Y'" on the gantt page, the gantt will filter - and if they then navigate to a report (bar chart) page, that will also be filtered for Key projects only.
To make this happen, I plan to have an identical sidebar on all these pages. This will contain maybe 8 dropdowns and tickboxes allowing the user to create or remove these filters. Eventually some users might save preferences for certain choices within these dropdowns.
Since the sidebar will almost always be identical from page to page, the smartest approach would seem to be to create one sidebar (as html region) and access that sidebar from all pages rather than copying the code from page to page. Then I thought I'd create application-level items in order to create global variables for each of the dropdowns.
My question is: is this approach possible? And can I create a "global" region in Page 0 and then access it from other pages? (This is how I thought it would work but I have tried and can't see how to do it.)

- we have user id parameter.can we update the parameter(:parameter.p_userid) before firing "WHEN NEW FORM INSTANCE TRIGGER"(when new form instance trigger contain code for tree node), for login another canvas as per user rights?
- i have created a login form in one canvas.
- also tree node Hierarchy form created on another canvas. now we want to login through login screen, after login only those forms should show in tree Hierarchy which users have rights. for this purpose we want to pass the parameter of userid before connecting to tree node form through the following query
SELECT COUNT (*)
INTO v_count
FROM usersinfo
WHERE usersname = :USERBLOCK.usernames AND passwords = :USERBLOCK.passwords ;
[code]...
Every thing is working but when we click on button in login form at that time parameter.p_userid will return null. because above code is define on button click in login screen, i cannot understand where i need to define the above code .

I'm setting up APEX REST security by following the instructions from [URL]...Everything works great according to document.
I can acquire a token, then passing it in the header to get needed data from REST service. Consumer acquires an token by going on web browser to [URL]...
It will be redirected to[URL]... asking for username and password on browser. Once entering them correctly, it will be directed to Redirect URI defined in the OAuth2 client with the token in the URL.
My question is that is it possible to do token acquiring by coding (like in Salesforce) without going to web browser? We've tried doing that, it will stop due to redirect to sign-on.

I am trying to create a custom package that creates users as well as modify user information in OID using DBMS_LDAP package. I was able to create the package but I am stuck on specifying the orcladmin password for the procedure DBMS_LDAP.simple_bind_s(my_session,'orcladmin','orcladminpwd');
I need to get the orcladmin password dynamically. Is there a way to achieve this?
We are planning to provide our application users the ability to add new users / modify their own OID information.

I have a simple tabular form based on a four element table: the primary key (seq #), title, Updated_by, Updated_timestamp.I would like to populate the updated_by and Updated_timestamp fields when a user either updates or adds to the table.On other forms, I use a calculation to update the page_ item in the page_processing section of APEX. However, in the tabular form, I am not sure where I might update these two fields.

I'm using Application Express 4.2.1.00.08
In the application, the authentication method used is the DB one, so the user (schema) must exist on the DB. This works fine.
For instance, I'm login as SCOTT
Creating the following query select upper(user) from dualshows that the real logged user is APEX_PUBLIC_USER and npot SCOTT.
How to create a connection with another "real" username ?

I am trying to redirect to different pages based on user inputs. I have a form in which I have one text item and a submit button. For example consider text item to be empno; So once the user enters a empno and hits submit button; I need to redirect to different pages based on this job.
For Ex:
if user inputs empno whose job is 'ANALYST' then redirect to page 1
if user inputs empno whose job is 'MANAGER' then redirect to page 10
For this scenario. i wrote a pl/sql process for the submit button; but no luck -- its not at all redirecting instead its in the same page. Below is the process.
declare
v_job varchar2(20);
begin
select job into v_job from emp where empno = :P9_EMPNO_R;
if v_job = 'ANALYST' then
OWA_UTIL.REDIRECT_URL('f?p=&APP_ID.:1:&SESSION.::&DEBUG.::', TRUE);
[code]....

APEX 4.1
11g db
Internet explorer 8
I have a region with 4 fields - ID, name, address, telephone. A user can search on any one of theses fields, depending on which field they search on the query is different e.g. Searching on telephone is a different query to searching on address. The query will bring back the same columns, so I just need one report.
How do I create a report where depending on the field the user searches on, it uses the same report but different query.

I have been requested to create a tabular form, but end user should have ability to hide/show columns, also they should rename the column headers. So I have created a table with column name called "attribute1", attribute2", etc. Based on that table, create a tabular form, which has column header as "attrbute1", "attrbute2", etc.
Now end user wants to rename attrbute1 as he wants. And he/she also wants to have a link called "hide/show" next to the column header, so end user can control which column they want to hide/show. It is so easy to do that control from developer side, however, shift that function to end user from front end seems very difficult to me
