How to migrate 10gR1 repository to OWB 11gR2?

Question

We are trying to migrate OWB 10gR1 repository to OWB 11gR2?
But are being faced with version compatibility issues.
Is there any work-around for the same?

Answer 1

This is a bit before my time, so I'm not very familiar with how the repository worked in 10gR1, but you might have a look at this... assuming you at least have the database credentials for the repository owner, it looks like you can perform user management tasks through this helper package that might get you an OWB user that can access everything, and let you move your design into 10.2 (from which you can migrate on to 11.2).

Maintaining Repository Users
Multiple identifiable Warehouse Builder users can access the same central repository schema when they are registered by the repository owner.
Warehouse Builder includes utility procedures for the following maintenance tasks:
* Update the role protecting password
Although the repository owner does not explicitly use the protecting password for the role, it is recommended that the repository owner change the password often.
The repository owner must connect to the repository schema using SQL Plus and issue the following statement:
Call WBSecurityHelper.updateRolePwd('newpwd');
where'newpwd' is the new password used to protect the role chosen by repository owner. The changed password encryption appears in the table called OWB_ROLE_INFO table.
* Register repository users
Warehouse Builder users must be database users located in the same database instance as the repository. The database user's default role should not be ALL. Use 'After user xxx DEFAULT Role x' to set the default role property.
To register a repository user, execute the following statement in SQL Plus:
call WBSecurityHelper.registerOWBUser ('username')
* Unregister repository users
To unregister a user from a repository, execute the following statement in SQL Plus:
Call WBSecurityHelper.unregisterOWBUser('username');
* List all repository users
The repository owner must connect to the database containing the repository and issue the following statement:
Set serveroutput on;
Call WBSecurityHelper.listOWBUser( );
Set serveroutput on is required since listOWBUser() uses the DBMS_OUTPUT.put_line for the output to dump the data to the user interface. Otherwise, DBMS_OUTPUT.put_line only dumps the output into an intermediate data structure.
The preceding user maintenance tasks should be performed in the repository by the repository owner.
