Server Configuration Checklist for Oracle Grid Infrastructure

Use this checklist to check minimum server configuration requirements for Oracle Grid Infrastructure installations.

Table 1-3 Server Configuration Checklist for Oracle Grid Infrastructure

Check Task
Disk space allocated to the temporary file system

At least 1 GB of space in the temporary disk space (/tmp) directory.
Swap space allocation relative to RAM

Between 4 GB and 16 GB: Equal to RAM
More than 16 GB: 16 GB
Note: If you enable HugePages for your Linux servers, then you should deduct the memory allocated to HugePages from the available RAM before calculating swap space.

HugePages memory allocation

Allocate memory to HugePages large enough for the System Global Areas (SGA) of all databases planned to run on the cluster, and to accommodate the System Global Area for the Grid Infrastructure Management Repository.

Mount point paths for the software binaries Oracle recommends that you create an Optimal Flexible Architecture configuration as described in the appendix "Optimal Flexible Architecture" in Oracle Grid Infrastructure Installation and Upgrade Guide for your platform.
Ensure that the Oracle home (the Oracle home path you select for Oracle Database) uses only ASCII characters

The ASCII character restriction includes installation owner user names, which are used as a default for some home paths, as well as other directory names you may select for paths.

Set locale (if needed)

Specify the language and the territory, or locale, in which you want to use Oracle components. A locale is a linguistic and cultural environment in which a system or program is running. NLS (National Language Support) parameters determine the locale-specific behavior on both servers and clients. The locale setting of a component determines the language of the user interface of the component, and the globalization behavior, such as date and number formatting.

Set Network Time Protocol for Cluster Time Synchronization

Oracle Clusterware requires the same time zone environment variable setting on all cluster nodes.

Ensure that you set the time zone synchronization across all cluster nodes using either an operating system configured network time protocol (NTP) or Oracle Cluster Time Synchronization Service.

Check Shared Memory File System Mount

By default, your operating system includes an entry in /etc/fstab to mount /dev/shm. However, if your Cluster Verification Utility (CVU) or Oracle Universal Installer (OUI) checks fail, then ensure that the /dev/shm mount area is of type tmpfs and is mounted with the following options:

  • rw and exec permissions set on it

  • Without noexec or nosuid set on it

Note: Your operating system usually sets these options as the default permissions. If they are set by the operating system, then they are not listed on the mount options.
