Oracle® Database Installation 10g Checking the Hardware for Solaris (SPARC 64-Bit)

Checking the Hardware Requirements

The system must meet the following minimum hardware requirements:
At least 1024 MB of physical RAM
The following table describes the relationship between installed RAM and the configured swap space requirement.
RAM
Swap Space
Between 1024 MB and 2048 MB
1.5 times the size of RAM
Between 2049 MB and 8192 MB
Equal to the size of RAM
More than 8192 MB
0.75 times the size of RAM
400 MB of disk space in the /tmp directory
Between 1.5 GB and 3.5 GB of disk space for the Oracle software, depending on the installation type
1.2 GB of disk space for a preconfigured database that uses file system storage (optional)


To determine the physical RAM size, enter the following command:

# /usr/sbin/prtconf grep "Memory size"

If the size of the physical RAM is less than the required size, then you must install more memory before continuing.
To determine the size of the configured swap space, enter the following command:

# /usr/sbin/swap -s


If necessary, refer to the operating system documentation for information about how to configure additional swap space.

To determine the amount of disk space available in the /tmp directory, enter the following command:

# df -k /tmp
# df -h /tmp (on Solaris 10)

If there is less than 400 MB of free disk space available in the /tmp directory, then complete one of the following steps:

Delete unnecessary files from the /tmp directory to meet the disk space requirement.

Set the TMP and TMPDIR environment variables when setting the oracle user's environment (described later).

Extend the file system that contains the /tmp directory. If necessary, contact your system administrator for information about extending file systems.
To determine the amount of free disk space on the system, enter the following command:

# df -k
# df -h (on Solaris 10)

To determine whether the system architecture can run the software, enter the following command:

# /bin/isainfo -kv
