- Do you have the correct OS? 11.2.0.4 requires older OS versions (e.g., RHEL 6 or 7, Windows Server 2008 R2 or 2012). It will not run on RHEL 9 or Windows Server 2022.
- Do you have a support identifier (CSI)? Without a valid CSI, you cannot legally apply critical security patches to 11.2.0.4, leaving your database vulnerable.
