Server Configuration Checklist for Oracle Grid Infrastructure

1.3 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 5 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
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.
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, 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: These options might not be listed as they are usually set as the default permissions by your operating system.
