Checking and Configuring Server Hardware for Oracle Database Client

Verify that servers where you install Oracle Database Client meet the minimum requirements for installation.

This section provides minimum server requirements to complete installation of Oracle Database Client. It does not provide system resource guidelines, or other tuning guidelines for particular workloads.

Logging In to a Remote System Using X Window System

This procedure explains how to run Oracle Universal Installer on a remote server when GUI applications cannot run locally. Start an X Window System session, configure the local X server to accept remote displays with xhost, connect to the target server using ssh -Y, and switch to the root user when required; repeat the process for each relevant installation user, such as oracle or grid.

Setting Remote Display and X11 Forwarding Configuration

Configure the DISPLAY environment variable to point to the local X display, using shell-specific syntax such as export DISPLAY=hostname:0 or setenv DISPLAY hostname:0. To prevent installation failures caused by X11 forwarding, create or edit each Oracle installation owner’s ~/.ssh/config, set ForwardX11 no, and ensure that the .ssh directory and its files have appropriately restricted ownership and permissions.

Checking Server Hardware and Memory Configuration

Verify the server’s readiness for Oracle software by checking physical memory, swap space, /tmp capacity, available memory and swap, processor architecture, and shared-memory configuration with /proc/meminfo, df, free, and uname. Install additional memory or swap, free or redirect temporary storage when necessary, preserve Oracle temporary directories, confirm the architecture matches the software release, and ensure /dev/shm is properly mounted with sufficient capacity.
