The Linux operating system has been widely accepted for supporting Oracle databases. Red Hat Enterprise Linux version 8.5 was used in the tests as this Linux flavor provides the stability, reliability, and security required for databases. The same best practice approach was taken with Red Hat Linux, as used for VMware. Linux best practices are integrated into each physical layer of recommendations. Thus, it is very easy to review Linux recommendations by reading CPU best practices or another physical layer.
The following table summarizes the software architecture used in validating best practices:
Table 4. Software architecture
Oracle database | Oracle Database EE 19c (19.0.0.0) with release update RU 19.15 |
Operating system | Red Hat Enterprise Linux 8.5 |
VMware vSphere | VMware 7.3 with vCenter 7.3 |
There are many possible combinations for the software architecture. In testing with Oracle Database19c, Red Hat Enterprise Linux 8.5, and VMware vSphere 7.3, the goal was to have a design that applies to most of our customers’ databases. Future best practice programs will address new versions of the Oracle database and advances in both the operating system and virtualization.
