Oracle Linux 6.4 Installation or Red Hat Enterprise Linux 6.4

Oracle Linux 6.4 Installation or Red Hat Enterprise Linux 6.4

System Requirements

Architecture

These instructions are for installing OLE 6  on an IA-32 system (i.e., a 32-bit Intel- or AMD-based system) and Opteron 64-bit systems (x86_64).

Minimum Memory

Red Hat recommends for 32 bit a minimum of 1GB memory/logical CPU, and for 64 bit a minimum of 1GB of memory, 1GB/logical CPU. At SLAC, RHEL6 has been successfully installed on systems with 512 MB, but such systems have a tendency to bog down badly due to excessive swapping when too many applications are open at once.

Minimum Disk Space

OCIO recommends a minimum disk size of above 12 GB, and a minimum root partition ("/") size of about 9 GB.
