Server Hardware and Software Review Checklist for Oracle RAC Installation

Review this checklist to ensure you have met the minimum hardware and software requirements for Oracle RAC.

Table 1-2 Hardware and Software Review Checklist for Oracle RAC

Check	Task
Operating System General Requirements	Prepare servers as described in Oracle Grid Infrastructure Installation Guide for your platform.
Review Existing Oracle Installations and Upgrade Plans	To install Oracle RAC 19c, you must have Oracle Grid Infrastructure (Oracle Clusterware and Oracle ASM) 19c installed on your cluster. The Oracle Clusterware version must be equal to or greater than the Oracle RAC version that you plan to install. For the most current updates and best practices about pre-upgrade, post-upgrade, compatibility, and interoperability discussions, refer to Support Note 1670757.1 on My Oracle Support. See Also: Oracle Database Upgrade Guide Oracle Grid Infrastructure Installation Guide
Server Hardware on each node	Use identical server hardware on each node, to simplify server maintenance.
Time Zone Requirement	Upgrade the Time Zone File and TSTZ Data: As part of an installation of Oracle Database 19c, time zone version files from 1 to 12 are installed in the following path: You can continue to use the current time zone version or upgrade to the latest version. Oracle recommends that you upgrade the server to the latest time zone version. See Oracle Database Globalization Support Guide for information about how to upgrade the time zone file and TSTZ data
Use Cluster Verification Utility (CVU)	Before you start your installation, use Cluster Verification Utility (CVU) to ensure that your system is prepared for Oracle RAC installation. If any checks fail, then fix the errors reported. Contact your system or storage administrators to have them fix errors manually. CVU is available in the Grid home, in the `bin` directory.
Ensure that Oracle RAC Databases You are Installing are Compatible with Existing Databases	If you have Oracle Clusterware installed, and different releases of other Oracle software installed, then the Oracle Clusterware release must be later than or equal to the Oracle Database software release. Oracle Clusterware and Oracle ASM are both upgraded to 19c when you perform an Oracle Grid Infrastructure 19c installation. If you have an existing Oracle home, then you can create a new Oracle home and install Oracle Database 19c into the new Oracle home. Ensure that Oracle Clusterware is in a separate Oracle Grid Infrastructure home. Oracle Grid Infrastructure for a Cluster installations cannot be installed in the Oracle home directory for Oracle Database.
Platform-Specific Server Configuration	Ensure an external jobs user is created for HP-UX. Configure a Windows Domain user account to use when installing Oracle RAC on Oracle ASM Cluster File System (Oracle ACFS) on Windows platforms.
