3.1 Memory Requirements
The following are the memory requirements for installing Oracle Database 11g Release
2 (11.2):
■ Minimum: 1 GB of RAM
Recommended: 2 GB of RAM or more
To determine the RAM size, enter the following command:
# grep MemTotal /proc/meminfo
If the size of the 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:
■ To determine whether the system architecture can run the software, enter the
following command:
# uname -m
To determine the size of the configured swap space, enter the following command:
# grep SwapTotal /proc/meminfo
If necessary, refer to the operating system documentation for information about how to
configure additional swap space.
To determine the available RAM and swap space, enter the following command:
# free
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
Between 1 GB and 2 GB 1.5 times the size of the RAM
Between 2 GB and 16 GB Equal to the size of the RAM
More than 16 GB 16 GB
Note: This command displays the processor type. Verify that the
processor architecture matches the Oracle software release to install. If
you do not see the expected output, then you cannot install the
software on this system.
