).
4. If you are not logged in as the

3 Checking the Hardware Requirements
The system must meet the following minimum hardware requirements:
■ Memory Requirements
■ System Architecture
■ Disk Space Requirements
3.1 Memory Requirements
The following are the memory requirements for installing Oracle Database 11g Release
2 (11.2):
■ At least 256 MB of physical RAM.
To determine the physical RAM size, enter the following command:
# grep MemTotal /proc/meminfo
If the size of the physical RAM is less than the required size, then you must install
more memory before continuing.
■ The following table describes the relationship between installed RAM and the
configured swap space recommendation:
Note: On Linux, the HugePages feature allocates non-swappable
memory for large page tables using memory-mapped files. If you
enable HugePages, then you should deduct the memory allocated to
HugePages from the available RAM before calculating swap space.
Available RAM Swap Space Required
256 MB 3 times the size of RAM
Between 256 MB and 512 MB 2 times the size of RAM
Between 512 MB and 2 GB 1.5 times the size of RAM
Between 2 GB and 16 GB Equal to the size of RAM
More than 16 GB 16 GB
