Can i change application schema at runtime?

Question

I created a workspace with 3 schema (for instance three different customers).
Just one application (starting with one of this three schema).
I'd like to know if it is possible to choose (by code) at runtime the schema to associate to the application.
thank you in advance to all.

Hi Seek78 !
"Otherwise you can create 3 different home page in 3 different apps, that call directly the 4 "Main" app where the business logic in. Typically 1 app per schema."
Let's say we have 2 applications : 100 et 101. I consider 101 is the main application.
- 100 runs with schema SA, login page calls the 101 application page 1 after a successful logon
- and 101 with schema SB, contains the business logic.
When I login to application 100, schema SA, if login is successful then I get to application 101. But data displayed is the one of schema SB.
This solution doesn't seem to work. Otherwise please indicate how I should implement the inheritance of the SA schema.
As for the "ALTER SESSION", I tried it in the login process of my login page, writing it in an anonymous bloc. But I get the error ORA-06550. Here is the code :
BEGIN
wwv_flow_custom_auth_std.login(
P_UNAME => :P101_USERNAME,
P_PASSWORD => :P101_PASSWORD,
P_SESSION_ID => v('APP_SESSION'),
P_FLOW_PAGE => :APP_ID||':1'
ALTER SESSION SET CURRENT_SCHEMA [MYSCHEMA];
END;
As APEX doesn't open a new database session when login a new user, where can we code this ALTER SESSION ?
Thanks for your help,
Fred.
