About CVU Fixup Scripts

During installation, for certain prerequisite check failures, you can click Fix & Check Again to generate a fixup script (runfixup.sh). You are then prompted by OUI to run the fixup script as the root user in a separate session. You must run the script on all the nodes specified by OUI.

The Fixup script does the following:

• Checks and sets kernel parameters to values required for successful installation, including:

  • Shared memory parameters

  • Semaphore parameters

  • Open file descriptor and UDP send/receive parameters

• Sets permissions on the Oracle Inventory (central inventory) directory.

• Reconfigures primary and secondary group memberships for the installation owner, if necessary, for the Oracle Inventory directory, and for the operating system privileges groups.

• Sets up virtual IP and private IP addresses in /etc/hosts.

• Sets shell limits to required values, if necessary.

• Installs the Cluster Verification Utility packages (cvuqdisk rpm).

Modifying the contents of the generated fixup script is not recommended.
