Use this procedure to gather information about your server configuration.
- Use the following command to determine physical RAM size on the server:
# grep MemTotal /proc/meminfoIf the size of the physical RAM installed in the system is less than the required size, then you must install more memory before continuing.
- Determine the size of the configured swap space:
# grep SwapTotal /proc/meminfoIf necessary, see your operating system documentation for information about how to configure additional swap space.
- Determine the amount of space available in the
# df -h /tmp
If the free space available in the
/tmpdirectory is less than what is required, then complete one of the following steps:
Delete unnecessary files from the
/tmpdirectory to meet the disk space requirement.
When you set the Oracle user's environment, also set the
TMPDIRenvironment variables to the directory you want to use instead of
- Determine the amount of free RAM and disk swap space on the system:
- Determine if the system architecture can run the software:
# uname -mVerify that the processor architecture matches the Oracle software release to install. For example, you should see the following for a x86-64 bit system:
If you do not see the expected output, then you cannot install the software on this system.
- Verify that shared memory (
/dev/shm) is mounted properly with sufficient size:
df -h /dev/shmThe
df-hcommand displays the filesystem on which
/dev/shmis mounted, and also displays in GB the total size and free size of shared memory.
