Ensure that you review information related to the platform on which you intend to install Oracle Database 1. Logging In to the System as root. Before you install the Oracle software, you must complete several tasks as the root user. To log in as the root user, complete one of the following procedures: Note. Unless you intend to complete a silent- mode installation, you must install the software from an X Window System workstation, an X terminal, or a PC or other system with X server software installed. Depending on the X server software that you are using, you may need to complete the tasks in a different order. Start the X server software. Configure the security settings of the X server software to permit remote hosts to display X applications on the local system. 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). If you are not logged in as the root user on the remote system, then enter the following command to switch user to root. Checking the Hardware Requirements. The system must meet the following minimum hardware requirements: 2. Memory Requirements. The following are the memory requirements for installing Oracle Database 1. Release 1: At least 1 GB of RAMTo determine the RAM size, enter the following command. Mem. Total /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 requirement: 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. RAMSwap Space. Between 1 GB and 2 GB1. RAMBetween 2 GB and 1. GBEqual to the size of RAMMore than 1. GB1. 6 GBTo determine the size of the configured swap space, enter the following command. Swap. Total /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. Oracle recommends that you take multiple values for the available RAM and swap space before finalizing a value. This is because the available RAM and swap space keep changing depending on the user interactions with the computer. Automatic Memory Management. Starting with Oracle Database 1. Automatic Memory Management feature requires more shared memory (/dev/shm)and file descriptors. The size of the shared memory should be at least the greater of MEMORY. The number of file descriptors for each Oracle instance should be at least 5. PROCESSES. Also, the limit of descriptors for each process should be at least 5. If file descriptors are not sized correctly, you will notice ORA- 2. Oracle processes and potentially Linux Error EMFILE (Too many open files) errors in non- Oracle processes. To determine the amount of shared memory available, enter the following command. Note: MEMORY. Note that the initialization parameters cannot be greater than the shared memory file system on the operating system. For example, if the shared memory file system allocation on your system is 1 GB, but you set Memory Size (MEMORY. 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. Disk Space Requirements. The following are the disk space requirements for installing Oracle Database 1. Release 1: Between 1. MB of disk space in the /tmp directory. To determine the amount of disk space available in the /tmp directory, enter the following command. If there is less than 4. 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 the system administrator for information about extending file systems. To determine the amount of free disk space on the system, enter the following command. The following table describes the disk space requirements for software files for each installation type on Linux 8. Installation Type. Requirement for Software Files (GB)Enterprise Edition. Standard Edition. Custom (maximum)3. Between 3. 5 GB and 5 GB of disk space for the Oracle software, depending on the installation type. The following table describes the disk space requirements for each installation type on Linux x. Installation Type. Requirement for Software Files (GB)Enterprise Edition. Standard Edition. Custom (maximum)4. Between 3. 5 GB and 5 GB of disk space for the Oracle software, depending on the installation type. The following table describes the disk space requirements for each installation type on Linux x. Installation Type. Disk Space for Data Files (GB)Enterprise Edition. Standard Edition. Custom (maximum)1. The following table describes the disk space requirements for each installation type on Linux x. Installation Type. Disk Space for Data Files (GB)Enterprise Edition. Standard Edition. Custom (maximum)2. Additional disk space, either on a file system or on an Automatic Storage Management disk group is required for the flash recovery area if you choose to configure automated backups. Recommended Hardware Requirement for SQL Developer. The following table lists the recommended Memory and Display requirements for SQL Developer. Resource. Recommended. Memory. 1 GB RAM (recommended), 2. MB RAM (min)Display. X 7. 68 resolution. Checking the Software Requirements. Depending on the products that you intend to install, verify that the following software are installed on the system. Note: This guide contains information required to install Oracle Database 1. Release 1 (1. 1. 1) on various platforms of Linux. Ensure that you review information related to the platform on which you intend to install Oracle Database 1. Oracle Universal Installer performs checks on the system to verify that it meets the listed requirements. To ensure that these checks pass, verify the requirements before you start Oracle Universal Installer. Operating System Requirements. The following are the operating system requirements for Oracle Database 1. Release 1: Note. Oracle Universal Installer performs checks to verify that the system meets the listed requirements. To ensure that these checks pass, verify the requirements before you start Oracle Universal Installer. On Linux x. 86 and Linux x. Asianux 2 SP2. Asianux 3. Oracle Linux 4. Oracle Linux 5. Red Hat Enterprise Linux 4. Red Hat Enterprise Linux 5. SUSE Linux Enterprise Server 1. To determine the distribution and version of Linux installed, enter the following command: # cat/proc/version. Note. Only the distributions and versions listed in the earlier list are supported. Do not install the software on other versions of Linux. Kernel Requirements. The following are the Kernel requirements for Oracle Database 1. Release 1: On Asianux 2, Oracle Linux 4, and Red Hat Enterprise Linux 4: 2. On Asianux 3, Oracle Linux 5, and Red Hat Enterprise Linux 5: 2. On SUSE Linux Enterprise Server 1. To determine whether the required kernel is installed, enter the following command. The following is a sample output displayed by running this command on a Red Hat Enterprise Linux 4. EL. In this example, the output shows the kernel version (2. EL) on the system.
