“Choose Connection” is NOT seen in Discoverer Plus and Discoverer Viewer screen after installation.
Installed Discoverer 10g as an OracleBI standalone installation (i.e., without associating with an OracleAS infrastructure).
Associated the standalone Discoverer to Oracle Apps Database.
Users are unable to see Choose Connection in the Discoverer Plus and Viewer login screen.
Discoverer has not been associated with an infrastructure. This happens when Discoverer 10g is installed as a Standalone without associating it with an OracleAS infrastructure.
Quoting from the documentation:
“An OracleBI standalone installation is not associated with an OracleAS Infrastructure, and therefore has a limited number of components available.
If Discoverer is not associated with an OracleAS Infrastructure, Discoverer connections are not available to end users. For more information about associating Discoverer with an Oracle Infrastructure install, see Chapter 2, "About Oracle Business Intelligence installations and OracleAS Infrastructures".”
2.2 How to associate an OracleBI installation with an OracleAS Infrastructure
If you install an OracleBI standalone installation, you might want to associate it with an Oracle Application Server Infrastructure in order to deploy Discoverer with other OracleAS components (e.g. Oracle Portal, Oracle Single Sign-On).
You can associate OracleBI Discoverer with either an OracleAS 9.0.4 Infrastructure or an OracleAS 10.1.2 Infrastructure.
Note: If you want to associate an OracleBI standalone installation with a 9.0.4 Infrastructure, you must also upgrade the Discoverer part of the MR to deploy Discoverer Portlet Provider (for more information, see Section 2.3, "How to upgrade a 9.0.4 metadata repository to work with Discoverer Portlet Provider Version 10.1.2 and Oracle Portal 10.1.2").
To associate an OracleBI standalone installation with an OracleAS Infrastructure:
Start a Web browser and enter the Application Server Control URL containing the fully qualified host name and domain of the OracleBI installation that you want to configure (for more information, see Section 5.1.2, "How to start Application Server Control and display the System Components page").
Display the Infrastructure tab.
In the Identity Management area, do one of the following:
to associate the OracleBI installation, click Configure to display the Configure Identity Management: Internet Directory page
to reassociate the OracleBI installation, click Change to display the Change Identity Management: Internet Directory page
Use the Host field and the Port field to enter the host name (e.g. infra.mycompany.com) and port number (e.g. 389) of the Oracle Internet Directory component on the OracleAS Infrastructure machine.
Hint: To find out the host name and port number values to specify, start Oracle Application Server Control on the OracleAS Infrastructure machine, display the Infrastructure tab, and note down the values of the Internet Directory Host field and the Internet Directory Port field.
Click Next to display the Configure Identity Management: Login page.
Use the User Name field and the Password fields to enter the administration user name and password for the Oracle Internet Directory component on the Infrastructure machine.
Hint: Prefix the user name value with cn= (e.g. cn=orcladmin).
Click Next to display the Configure Identity Management: Validation page.
Having configured Identity Management, you now configure the Metadata Repository.
In the Metadata Repository area, click Configure to display the Configure Repository: Internet Directory page.
Follow the steps in the Configure/Change Repository: Internet Directory wizard, then click Finish.
The OracleBI standalone installation is now associated with an OracleAS Infrastructure. You can now deploy Discoverer with other OracleAS components (i.e. Oracle Portal, Oracle Single Sign-On) and use Discoverer connections and Discoverer Portlet Provider.
