Log in as
root, and use the following instructions to locate or create the Oracle Inventory group, and create a software owner for Oracle Grid Infrastructure, and directories for Oracle home.
Oracle software installations require an installation owner, an Oracle Inventory group, which is the primary group of all Oracle installation owners, and at least one group designated as a system privileges group. Review group and user options with your system administrator. If you have system administration privileges, then review the topics in this section and configure operating system groups and users as needed.
