Cluster System Plan

Cluster System Plan

At least 1 GB system memory is required for installing Oracle RAC. Considering memory pre-allocation mechanism used by Oracle databases and database performance, you are advised to configure larger memory. Table 1-3 provides the recommended size for the random access memory (RAM) and swap partition.

NOTE:

After Oracle RAC is installed, 20 GB is allocated to the swap partition by default. You can change the value based on service requirements.
