You can use the -fixup flag with certain CVU commands to generate fixup scripts before installation. Oracle Universal Installer can also generate fixup scripts during installation. The installer then prompts you to run the script as root in a separate terminal session. If you generate a fixup script from the command line, then you can run it as root after it is generated. When you run the script, it raises kernel values to required minimums, if necessary, and completes other operating system configuration.
Alternatively, you can specify the -method parameter with certain CVU commands to enable privilege delegation and enable you to run fixup scripts as root on remote nodes from the local node.
