procedure. Depending on the X server software that you are using, you may need to complete the tasks in a different order.

1. Start the X server software.

2. Configure the security settings of the X server software to permit remote hosts to display X applications on the local system.

3. Connect to the remote system where you want to install the software, and start a terminal session on that system, for example, an X terminal (xterm).

4. If you are not logged in as the root user on the remote system, then enter the following command to switch user to root:

   $ su - root password: #

3 Checking the Hardware Requirements

The system must meet the following minimum hardware requirements:

• At least 1024 MB of physical RAM

• The following table shows the relationship between the available RAM and the required swap space.

  Available RAMSwap Space RequiredBetween 1024 MB and 2048 MB1.5 times the size of RAMBetween 2049 MB and 8192 MBEqual to the size of RAMMore than 8192 MB0.75 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 ensure that the system meets these requirements, follow these steps:

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

   # grep MemTotal /proc/meminfo

   If the size of the physical RAM installed in the system is less than the required size, then you must install more memory before continuing.

2. To determine the size of the configured swap space, enter the following command:

   # grep SwapTotal /proc/meminfo

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

3. To determine the available RAM and swap space, enter the following command:

   # free

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

   # df -k /tmp

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

   • Delete unnecessary files from the /tmp directory.

   • 
     

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

   • Extend the file system that contains the /tmp directory. If required, contact your system administrator for information about extending file systems.

5. To determine the amount of free disk space available on the system, enter the following command:

   # df -k

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

   # grep "model name" /proc/cpuinfo

   This command displays the processor type. Verify that the processor architecture matches the Oracle software release that you want to install. If you do not see the expected output, then you cannot install the software on this system.

4 Checking the Software Requirements

The system must meet the following minimum software requirements, depending on the distribution and version of your operating system:

Note:

Oracle Universal Installer performs checks on your system to verify that it meets the listed requirements. To ensure that these checks pass, verify the requirements before you start Oracle Universal Installer.

• The operating system must be one of the following:

  
  

  • Red Hat Enterprise Linux 3.0 (Update 3 or later)

  • Red Hat Enterprise Linux 4.0

  • SUSE Linux E
