How do you upgrade the Oracle client in Linux RHEL 4 (64-bit) from 10.2.0.1 to 10.2.0.4? I need to upgrade a 64-bit linux oracle client install from 10.2.0.1 to 10.2.0.4. Our helpful DBAs insist that the only way they know how is with the GUI-based patch thing. Is there really no command-line patch I can apply? If so, where do I find it?
