Application To Have Access To 2 Different Data Sources?
Oct 25, 2010
I would like my application to have access to 2 different data sources [reached by two different database links]:
- DS_ONLINE that would be the main data source dedicated for an ONLINE access
- DS_OFFLINE, consisting of some materialized views which would refer to the objects of the DS_ONLINE data source, maintained in case of the DS_ONLINE's temporary inaccessibility A flag DS_ONLINE_ACCESS_FLAG indicating the DS_ONLINE's accessibility would be maintained.
I would like to make the choice of the current data source TRANSPARENT to my PL/SQL application [I wouldn't like the logic of determining the current data source to be embedded in my application code]. How can I do it?
I thought I could write the code as follows:
OPEN CURSOR c FOR
SELECT A, B, C FROM TABLE_SYNONYM;
Where the definition of the TABLE_SYNONYM would change in function of the DS_ONLINE_ACCESS_FLAG flag.
It could be done as DDL statement of "create or replace synonym ..." placed in a procedure dedicated to set the DS_ONLINE_ACCESS_FLAG flag...
...but I'm not sure if it is going to work and even so

issue with my apex line chart. The scenario is as follows: have a table called revenue. revenues per year are saved in it. and revenues are generated from three sources which are also saved in the same table. I have made a line chart on it. works well.
Now I have to show that if the value of one of the sources had fallen, how must have it affected the total. I made a number field that takes an estimated change value, and build my sql query with it. it works but the problem is that it changes the non-affected source too. it must change the value of the affected source only and hence the total value.
bold or I will put it this way, how can I write a select statement for a chart series so that one of the rows value does not change and the other two change.

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?

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?

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 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]....

Our oracle database has been running great. This past wendesday the application was unable to access a specific table. Sutting down and restarting the database seemed to have fixed the issue. Last night the database has been working since that restart on wednesday morning. Suddenly stopped working. We stopped and restarted the database again this time getting ORA-00600 error as shown below. We are able to make a connection to the database and can even access the tables in question. The application is complaining about the connection to the database. I understand that ORA-00600 is an internal error what I need to know is what the internal error code 549 actually is. I have tried googling to no avail.

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.)

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.

Is there a way to apply changes to a data field on oracle forms for specific users?
For example, I have an oracle form that applies the below masking code for a certain field called CUSTOMER_ID
IF :SYSTEM.BLOCK_STATUS = 'QUERY' THEN
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_TRUE);
ELSE
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_FALSE);
END IF;
But I only want this masking to be applicable to CERTAIN users. For example, the psuedo code would be like
IF :SYSTEM.BLOCK_STATUS = 'QUERY' and USERS_LIST = 'SUPERVISORS' THEN
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_TRUE);
Note that this users_list is a group of oracle database users, so I am a member of this group. Also note that this form is applied via the web via the application server.

I am trying to access and modify data of a table of another schema which contains 80,000-90,000 records. My procedure is taking near about 30 mins to complete the operation. faster access and updation of table data.
Details:
I have two schema: TEST and PROD
I am running the below code from TEST Schema.
/* CODE START HERE*/
DECLARE
exc_bulk_errors EXCEPTION;
PRAGMA EXCEPTION_INIT (exc_bulk_errors, -24381);
v_block_count NUMBER := 1000;
[Code]....
The above code is taking near about 30mins to process.
I have also tried another approch: Creating a procedure in PROD schema to update COMPONENT_MASTER table and by calling the procedure from above code by passing component code.
/* PROCEDURE CALL FROM ABOCE CODE INTEST SCHEMA*/
PROD.PROCEDURE_TO_UPDATE(v_comp_code);
But still it is taking same time.

This is for few applications to comply with with export control rules. The thin support by Customer DBA will be allowed to access the Data, if required .
1) Web Based Interface ?.
2) DB Encryption (But if we encrypt ALL columns Serious performance issue expected, File level will not restrict DB level access)
3) Special setting on DB (DBA to do only backup and restoration related work only - But cannot access data)
4) Standard Tools / Utilities / Others ??.

Is it possible for Access to extract data from an Oracle database and upload it directly?
Currently we have a business process where data is being extracted in scheduled queries (30+) to Excel spreadsheets, then manually edited to remove heading lines and imported to an Access database. I see an opportunity to automate a time consuming manual activity by having the Access db extract the data and directly upload it.
