on rhel I am running 10.2.0.1 and want to apply patchset 10.2.0.2 Here is what I am running into when I run the Oracle Installer: 1. clicking on installed products or Deinstall Products tells me there are no installed products 2. clicking on the next button tells me "Unable to create a new central inventory at location....." 3. If I point the inventory to a new location, the drop down button for Name and Path is greyed out, telling me that the installer does not see the current crs and db installation. I have set my environmental variables and check that I am logged in as Oracle. Also, since crs and db are bundled together in the patchset, how do I upgraded the crs first? thanks Randy
