November 2005
This guide describes how to quickly install Oracle Database Client on Linux x86 systems. It includes information about the following:
This guide describes how to complete a default installation of Oracle Database Client on a system that does not have any Oracle software installed on it. It describes how to install one of the following installation types:
Administrator: Enables applications to connect to an Oracle Database instance on the local system or on a remote system. It also provides tools that enable you to administer Oracle Database.
Runtime: Enables applications to connect to an Oracle Database instance on the local system or on a remote system.
Instant Client: Enables you to install only the shared libraries required by Oracle Call Interface (OCI), Oracle C++ Call Interface (OCCI), Pro*C, or Java database connectivity (JDBC) OCI applications. This installation type requires much less disk space as compared to the other Oracle Database Client installation types.
See Also:
Oracle Call Interface Programmer's Guide for more information about Instant ClientThis guide does not describe how to install the Custom installation type.
Where to Get Additional Installation Information
For more detailed information about installing Oracle Database Client, refer to Oracle Database Client Installation Guide for Linux x86.
This guide is available on the product disc. To access it, use a Web browser to open the welcome.htm file located in the top-level directory of the installation media, and then select the Documentation tab.
Before you install Oracle Database Client, you must complete several tasks as the root user. To log in as the root user, complete one of the following procedures:
Note:
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.If you are installing the software from an X Window System workstation or X terminal, then:
Start a local terminal session, for example, an X terminal (xterm).
If you are not installing the software on the local system, then enter the following command to enable the remote host to display X applications on the local X server:
$ xhost fully_qualified_remote_host_name
For example:
$ xhost somehost.us.acme.com
If you are not installing the software on the local system, then use the ssh, rlogin, or telnet command to connect to the system where you want to install the software:
$ telnet fully_qualified_remote_host_name
If you are not logged in as the root user, then enter the following command to switch user to root:
$ su - root password: #
If you are installing the software from a PC or other system with X server software installed, then:
Note:
If necessary, refer to the X server documentation for more information about completing this procedure. 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:
$ su - root password: #
The system must meet the following minimum hardware requirements:
512 MB of physical RAM
The following table gives the swap space requirement in terms of available RAM.
| Available RAM | Swap Space Required |
|---|---|
| Up to 512 MB | 3 times the size of RAM |
| Between 257 MB and 512 MB | 2 times the size of RAM |
| Between 513 MB and 726 MB | 1.5 times the size of RAM |
| More than 726 MB | 0.75 times the size of RAM |
The minimum client installation TMP space required is 115 MB. The minimum disk space requirement in the /tmp directory depends on the installation type you have selected. The following table lists the minimum disk space requirements for the /tmp directory in each type of installation.
| Installation Type | Disk Space Required for the /tmp Directory (MB) |
|---|---|
| Admin | 850 |
| Runtime | 470 |
| Custom (all components selected) | 780 |
| Instant | 150 |
The disk space requirement for each installation type is given in the following table.
| Installation Type | Requirement for Software Files (MB) |
|---|---|
| Instant Client | 130 |
| Administrator | 850 |
| Runtime | 495 |
| Custom (maximum) | 790 |
Note:
If you want to configure only the Instant Client Light component of Instant Client, you need 34 MB of disk space to store the related files. To configure Instant Client Light, refer to the Oracle Database Client Installation Guide for Linux x86.To ensure that the system meets these requirements:
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 specified value, then you must install more memory before continuing.
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.
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 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 available on the system, enter the following command:
# df -k
This command displays the disk space usage on all mounted file systems. You must identify a file system with sufficient disk space.
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.
The system must meet the following minimum software requirements.
To ensure that the system meets these requirements:
To determine which version of the operating system is installed, enter the following command:
# cat /etc/issue
Note:
Only the distributions and versions listed earlier in this section are supported. Do not install the software on other versions of Linux.To determine whether the required kernel is installed, enter the following command:
# uname -r
On a Red Hat Enterprise Linux 3.0 system, the output may be as follows:
2.4.21-27.EL
In this example, the output shows the kernel version (2.4.21) and errata level (27.EL). If the errata level is less than 27, then install the latest kernel update. Kernel updates are available from the Red Hat Network.
On a SUSE Linux Enterprise Server 9 system, the output may be as follows:
2.6.5-7.97
In this example, the output shows the kernel version on the system. If the kernel version is less than 2.6.5-7.97, then contact SUSE for information about obtaining and installing the kernel updates.
To determine whether the required packages are installed, enter commands similar to the following:
# rpm -q package_name
If a package is not installed, or if the version is lower than the required version, then install it from your Linux distribution media or download the required package from your Linux vendor's Web site.
The following local operating system group and user must exist on the system:
The Oracle Inventory group (oinstall)
The Oracle software owner (oracle)
To determine if this group and user already exist, and if required, to create them, follow these steps:
To determine if the oinstall group exists, enter the following command:
# more /etc/oraInst.loc
If the output of this command shows the oinstall group name, then the group already exists.
If the oraInst.loc file exists, then the output from this command is similar to the following:
inventory_loc=/u01/app/oracle/oraInventory inst_group=oinstall
The inst_group parameter shows the name of the Oracle Inventory group (oinstall).
If necessary, enter the following command to create the oinstall group:
# /usr/sbin/groupadd oinstall
To determine whether the oracle user exists and belongs to the correct groups, enter the following command:
# id oracle
If the oracle user exists, then this command displays information about the groups to which the user belongs. The output should be similar to the following, indicating that oinstall is the primary group:
uid=440(oracle) gid=200(oinstall) groups=201(dba),202(oper)
If necessary, complete one of the following actions:
If the oracle user exists, but its primary group is not oinstall, then enter a command similar to the following, where the -g option specifies oinstall as the primary group and the -G option specifies any existing groups to which the oracle user belongs:
# /usr/sbin/usermod -g oinstall [-G dba] oracle
If the oracle user does not exist, then enter the following command to create it:
# /usr/sbin/useradd -g oinstall [-G dba] oracle
This command creates the oracle user and specifies:
oinstall as the primary group
dba as an optional secondary group
Enter the following command to set the password of the oracle user:
# passwd oracle
Note:
You need not perform this procedure if an Oracle base directory already exists on the system. If you determine that theoinstall group exists, then, typically, the Oracle base directory is the parent directory of the Oracle Inventory directory.To create the Oracle base directory:
Enter the following command to display information about all mounted file systems:
# df -h
This command displays information about all the file systems mounted on the system, including:
The physical device name
The total amount, used amount, and available amount of disk space
The mount point directory for that file system
From the display, identify either one or two file systems that meet the disk space requirements mentioned earlier in this section.
Note the name of the mount point directory for each file system that you identified.
Enter commands similar to the following to create the recommended subdirectories in the mount point directory that you identified and set the appropriate owner, group, and permissions on them:
# mkdir -p /mount_point/app/oracle_sw_owner # chown -R oracle:oinstall /mount_point/app/oracle_sw_owner # chmod -R 775 /mount_point/app/oracle_sw_owner
For example, if the mount point you identify is /u01 and oracle is the user name of the Oracle software owner, then the recommended Oracle base directory path is as follows:
/u01/app/oracle
You run Oracle Universal Installer from the oracle account. However, before you start Oracle Universal Installer, you must configure the environment of the oracle user. To configure the environment, you must:
Set the default file mode creation mask (umask) to 022 in the shell startup file.
Set the DISPLAY environment variable.
To set the oracle user's environment:
Start a new terminal session, for example, an X terminal (xterm).
Enter the following command to ensure that X Window applications can display on this system:
$ xhost fully_qualified_remote_host_name
Complete one of the following steps:
If the terminal session is not connected to the system where you want to install the software, then log in to that system as the oracle user.
If the terminal session is connected to the system where you want to install the software, then switch user to oracle:
$ su - oracle
To determine the default shell for the oracle user, enter the following command:
$ echo $SHELL
Open the oracle user's shell startup file in any text editor:
Bash shell (bash) on Red Hat:
$ vi .bash_profile
Bourne shell (sh), Bash shell on SUSE (bash), or Korn shell (ksh):
$ vi .profile
C shell (csh or tcsh):
% vi .login
Enter or edit the following line in the shell startup file, specifying a value of 022 for the default file mode creation mask:
umask 022
If the ORACLE_SID, ORACLE_HOME, or ORACLE_BASE environment variable is set in the file, then remove the corresponding lines from the file.
Save the file, and exit from the editor.
To run the shell startup script, enter the following command:
Bash shell on Red Hat:
$ . ./.bash_profile
Bourne shell, Bash shell on SUSE, or Korn shell:
$ . ./.profile
C shell:
% source ./.login
If you are not installing the software on the local system, then enter a command similar to the following to direct X applications to display on the local system:
Bourne, Bash, or Korn shell:
$ DISPLAY=local_host:0.0 ; export DISPLAY
C shell:
% setenv DISPLAY local_host:0.0
In this example, local_host is the host name or IP address of the system that you want to use to display Oracle Universal Installer (your workstation or PC).
If you determined that the /tmp directory had insufficient free disk space when checking the hardware requirements, then identify a file system with the required amount of free space and set the TMP and TMPDIR environment variables as follows:
Use the df -h command to identify a suitable file system with sufficient free space.
If necessary, enter commands similar to the following to create a temporary directory on the file system that you identified, and set the appropriate permissions on the directory:
$ su - root # mkdir /mount_point/tmp # chmod a+wr /mount_point/tmp # exit
Enter commands similar to the following to set the TMP and TMPDIR environment variables:
Bourne, Bash, or Korn shell:
$ TMP=/mount_point/tmp $ TMPDIR=/mount_point/tmp $ export TMP TMPDIR
C shell:
% setenv TMP /mount_point/tmp % setenv TMPDIR /mount_point/tmp
Enter the following commands to ensure that the ORACLE_HOME and TNS_ADMIN environment variables are not set:
Bourne, Bash, or Korn shell:
$ unset ORACLE_HOME $ unset TNS_ADMIN
C shell:
% unsetenv ORACLE_HOME % unsetenv TNS_ADMIN
To verify that the environment has been set correctly, enter the following commands:
$ umask $ env | more
Verify that the umask command displays a value of 22, 022, or 0022 and the environment variables that you set in this section have the correct values.
On most Linux systems, the product disc mounts automatically when you insert it into the drive. If the disc does not mount automatically, then follow these steps to mount it:
Switch user to root:
$ su - root
If necessary, enter a command similar to the following to eject the currently mounted disc, then remove it from the drive:
Red Hat:
# eject /mnt/dvd
SUSE:
# eject /media/dvd
In these examples, /mnt/dvd and /media/dvd are the mount point directories for the disc drive.
Insert the disc into the disc drive.
To verify that the disc mounted automatically, enter a command similar to the following:
Red Hat:
$ ls /mnt/dvd
SUSE:
$ ls /media/dvd
If this command fails to display the contents of the disc, then enter a command similar to the following:
Red Hat:
# mount -t iso9660 /dev/dvd /mnt/dvd
SUSE:
# mount -t iso9660 /dev/dvd /media/dvd
In these examples, /mnt/dvd and /media/dvd are the mount point directories for the disc drive.
After configuring the oracle user's environment, start Oracle Universal Installer and install the Oracle software as follows:
To start Oracle Universal Installer, enter the following command:
$ /mount_point/client/runInstaller
If Oracle Universal Installer does not start, then refer to Oracle Database Installation Guide for Linux x86 for information about how to troubleshoot X display problems.
