Simple scenario - customer has installed OSB 11g and now wants to leverage OSR.
So the pre-requisites are fulfilled -
Oracle DB e.g. XE already installed
OSB 11g already installed
-- WLS - oepe111150_wls1033_win32.exe
-- OSB - ofm_osb_generic_22.214.171.124.0_disk1_1of1.zip
OSR will be installed in a separate WLS domain.
If you need to install in the same domain then please refer to -
Point to XE JDBC driver
Post Install Configuration
Create a new WLS domain for OSR
Start OSB Server and login to sbconsole
Test the Project Explorer Link and create a new project
Start the OSR admin & managed servers
