2 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:

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

- Following are the steps for installing the software from an X Window System workstation or X terminal:

1. Start a local terminal session, for example, an X terminal (xterm).

2. 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.example.com

3. 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

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

$ sudo sh
password:
#

- Following are the steps for installing the software from a PC or other system with X server software:

Note:

If necessary, refer to your X server documentation for more information about completing this procedure. Depending on the X server software that you are using, you may have 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:

$ sudo sh
password:
#

3 Checking the Hardware Requirements

The system must meet the following minimum hardware requirements:

- Memory Requirements

- System Architecture

- Disk Space Requirements

3.1 Memory Requirements

The following are the memory requirements for installing Oracle Database 11g Release 2 (11.2):

- Minimum: 1 GB of RAM
Recommended: 2 GB of RAM or more

To determine the RAM size, enter the following command:

# grep MemTotal /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 recommendation:

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.

Available RAM

Swap Space Required

Between 1 GB and 2 GB

1.5 times the size of the RAM

Between 2 GB and 16 GB

Equal to the size of the RAM

More than 16 GB

16 GB

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

# uname -m

Note:

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

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

# grep SwapTotal /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:

# free

IMPORTANT:

- 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.

- Contact your operating system vendor for swap space allocation guidance for your server. The vendor guidelines supersede the swap space requirements listed in this guide.

Automatic Memory Management

Starting with Oracle Database 11g, the Automatic Memory Management feature requires more shared memory (/dev/shm)and file descriptors. The shared memory should be sized to be at least the greater of MEMORY_MAX_TARGET and MEMORY_TARGET for each Oracle instance on that computer.

To determine the amount of shared memory available, enter the following command:

# df -h /dev/shm/

Note:

MEMORY_MAX_TARGET and MEMORY_TARGET cannot be used when LOCK_SGA is enabled or with HugePages on Linux.

3.2 System Architecture

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

# uname -m

Note:

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

3.3 Disk Space Requirements

The following are the disk space requirements for installing Oracle Database 11g Release 2 (11.2):

- At least 1 GB of disk space in the /tmp directory
To determine the amount of disk space available in the /tmp directory, enter the following command:

# df -h /tmp

If there is less than 1 GB 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.

See Also:

"Configuring the oracle User's Environment" for more information about setting TMP and TMPDIR

- 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:

# df -h

- The following tables describe the disk space requirements for software files, and data files for each installation type on Linux x86-64:

Installation Type

Requirement for Software Files (GB)

Enterprise Edition

4.35

Standard Edition

4.22

Installation Type

Requirement for Data Files (GB)

Enterprise Edition

1.7

Standard Edition

1.5

Additional disk space, either on a file system or on an Oracle Automatic Storage Management disk group is required for the fast recovery area if you choose to configure automated backups.

4 Checking the Software Requirements

Depending on the products that you intend to install, verify that the following softwares are installed on the system.

- Operating System Requirements

- Kernel Requirements

- Package Requirements

- Compiler Requirements

- Additional Software Requirements

Note:

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.

4.1 Operating System Requirements

The following or later versions of the operating system are required for Oracle Database 11g Release 2 (11.2):

- Asianux Server 3 SP2

Starting with Oracle Database 11g Release 2 (11.2), the Security Enhanced Linux (SE Linux) feature is supported for Oracle Linux 4, Red Hat Enterprise Linux 4, Oracle Linux 5, and Red Hat Enterprise Linux 5.

Note:

For Asianux Server, Oracle Linux, and Red Hat Enterprise Linux, system requirements are identical by kernel version. Specifically:

- Oracle Linux 4 and Red Hat Enterprise Linux 4 requirements are the same.

- Asianux Server 3, Oracle Linux 5, and Red Hat Enterprise Linux 5 requirements are the same.

- Oracle Unbreakable Enterprise Kernel for Linux 5 Update 5 (2.6.32) and above, available for x86-64 systems, contains several additional features and performance enhancements not available either with Oracle Linux or with other supported Linux distributions. This kernel can be installed on either Oracle Linux or Red Hat Enterprise Linux distributions. Before installing the Oracle Unbreakable Enterprise Kernel, you must have Oracle Linux 5 Update 5 or Red Hat Enterprise Linux 5 Update 5 installed on an x86-64 server.

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.

4.2 Kernel Requirements

To determine whether the required kernel is installed, enter the following command:

# uname -r

The following is a sample output displayed by running this command on an Oracle Linux 5.0 system:

2.6.18-128.el5PAE

In this example, the output shows the kernel version (2.6.18) and errata level (-128.el5PAE) on the system.

If the kernel version does not meet the requirement specified earlier in this section, then contact the operating system vendor for information about obtaining and installing kernel updates.

4.3 Package Requirements

The following are the list of packages required for Oracle Database 11g Release 2 (11.2):

Note:

- Oracle recommends that you install your Linux operating system with the default software packages (RPMs), unless you specifically intend to perform a minimal installation, and follow the directions for performing such an installation to ensure that you have all required packages for Oracle software.

- Oracle recommends that you do not customize RPMs during a default operating system installation. A default installation includes most required packages, and helps you to limit manual checks of package dependencies.

- If you did not perform a default Linux installation, you intend to use LDAP, and you want to use the scripts odisrvreg, oidca, or schemasync, then install the Korn shell RPM for your Linux distribution.

- You must install the packages (or later versions) listed in the following table. Also, ensure that the list of RPMs and all the prerequisites for these RPMs are installed.

- If you are using Oracle Unbreakable Enterprise Kernel, then all required kernel packages are installed as part of the Oracle Unbreakable Enterprise Kernel installation.

5 Creating Required Operating System Groups and Users

The following local operating system groups and users are required if you are installing Oracle Database:

- The Oracle Inventory group (typically, oinstall)

- The OSDBA group (typically, dba)

- The Oracle software owner (typically, oracle)

- The OSOPER group (optional. Typically, oper)

To determine whether these groups and users exist, and if necessary, to create them, follow these steps:

1. To determine whether 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 exists.

If the oraInst.loc file exists, then the output from this command is similar to the following:

inventory_loc=/u01/app/oraInventory
inst_group=oinstall

The inst_group parameter shows the name of the Oracle Inventory group, oinstall.

2. To determine whether the dba group exists, enter the following command:

# grep dba /etc/group

If the output from this commands shows the dba group name, then the group exists.

3. If necessary, enter the following commands to create the oinstall and dba groups:

# /usr/sbin/groupadd oinstall
# /usr/sbin/groupadd dba

4. 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 and dba is a secondary group:

uid=440(oracle) gid=200(oinstall) groups=201(dba),202(oper)

5. If necessary, complete one of the following actions:

- If the oracle user exists, but its primary group is not oinstall or it is not a member of the dba group, then enter the following command:

# /usr/sbin/usermod -g oinstall -G dba oracle

- If the oracle user does not exist, 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 and dba as the secondary group.

6. Enter the following command to set the password of the oracle user:

# passwd oracle

6 Configuring Kernel Parameters

Verify that the kernel parameters shown in the following table are set to values greater than or equal to the minimum value shown. The procedure following the table describes how to verify and set the values.

Note:

The kernel parameter and shell limit values in this section are minimum values only. For production database systems, Oracle recommends that you tune these values to optimize the performance of the system. Refer to your operating system documentation for more information about tuning kernel parameters.

Note: This value limits concurrent outstanding requests and should be set to avoid I/O subsystem failures.

/proc/sys/fs/aio-max-nr

Note:

If the current value of any parameter is higher than the value listed in this table, then do not change the value of that parameter.

To view the current value specified for these kernel parameters, and to change them if necessary:

- Enter commands similar to the following to view the current values of the kernel parameters:

Note:

Make a note of the current values and identify any values that you must change.

Parameter

Command

semmsl, semmns, semopm, and semmni

# /sbin/sysctl -a | grep sem
This command displays the value of the semaphore parameters in the order listed.

shmall, shmmax, and shmmni

# /sbin/sysctl -a | grep shm

file-max

# /sbin/sysctl -a | grep file-max

ip_local_port_range

# /sbin/sysctl -a | grep ip_local_port_range

rmem_default

# /sbin/sysctl -a | grep rmem_default

rmem_max

# /sbin/sysctl -a | grep rmem_max

wmem_default

# /sbin/sysctl -a | grep wmem_default

wmem_max

# /sbin/sysctl -a | grep wmem_max

- If the value of any kernel parameter is different from the recommended value, then complete the following steps:

1. Using any text editor, create or edit the /etc/sysctl.conf file, and add or edit lines similar to the following:

Note:

Include lines only for the kernel parameter values to change. For the semaphore parameters (kernel.sem), you must specify all four values. However, if any of the current values are larger than the minimum value, then specify the larger value.

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586

By specifying the values in the /etc/sysctl.conf file, they persist when you restart the system. However, on SUSE Linux Enterprise Server systems, enter the following command to ensure that the system reads the /etc/sysctl.conf file when it restarts:

# /sbin/chkconfig boot.sysctl on

2. Enter the following command to change the current values of the kernel parameters:

# /sbin/sysctl -p

Review the output from this command to verify that the values are correct. If the values are incorrect, edit the /etc/sysctl.conf file, then enter this command again.

3. Enter the command /sbin/sysctl -a to confirm that the values are set correctly.

4. On SUSE systems only, enter the following command to cause the system to read the /etc/sysctl.conf file when it restarts:

# /sbin/chkconfig boot.sysctl on

5. On SUSE systems only, you must enter the GID of the oinstall group as the value for the parameter /proc/sys/vm/hugetlb_shm_group. Doing this grants members of oinstall a group permission to create shared memory segments.
For example, where the oinstall group GID is 501:

# echo 501 > /proc/sys/vm/hugetlb_shm_group

After running this command, use vi to add the following text to /etc/sysctl.conf, and enable the boot.sysctl script to run on system restart:

vm.hugetlb_shm_group=501

Note:

Only one group can be defined as the vm.hugetlb_shm_group.

6. After updating the values of kernel parameters in the /etc/sysctl.conf file, either restart the computer, or run the command sysctl -p to make the changes in the /etc/sysctl.conf file available in the active kernel memory.

Check Resource Limits for the Oracle Software Installation Users

For each installation software owner, check the resource limits for installation, using the following recommended ranges:

Table 1 Installation Owner Resource Limit Recommended Ranges

Resource Shell Limit

Resource

Soft Limit

Hard Limit

Open file descriptors

nofile

at least 1024

at least 65536

Number of processes available to a single user

nproc

at least 2047

at least 16384

Size of the stack segment of the process

stack

at least 10240 KB

at least 10240 KB, and at most 32768 KB

To check resource limits:

1. Log in as an installation owner.

2. Check the soft and hard limits for the file descriptor setting. Ensure that the result is in the recommended range. For example:

$ ulimit -Sn
4096
$ ulimit -Hn
65536

3. Check the soft and hard limits for the number of processes available to a user. Ensure that the result is in the recommended range. For example:

$ ulimit -Su
2047
$ ulimit -Hu
16384

4. Check the soft limit for the stack setting. Ensure that the result is in the recommended range. For example:

$ ulimit -Ss
10240
$ ulimit -Hs
32768

5. Repeat this procedure for each Oracle software installation owner.

If necessary, update the resource limits in the /etc/security/limits.conf configuration file for the installation owner. For example, add the following lines to the /etc/security/limits.conf file:

oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  1024
oracle              hard    nofile  65536
oracle              soft    stack   10240

Note:

- The values mentioned in this example are illustrative and not actual values that must be added.

- When the limits.conf file is changed, these changes take effect immediately. However, if the grid or oracle users are logged in, then these changes do not take effect until you log these users out and log them back in. You must do this before you attempt to use these accounts to install.

7 Creating Required Directories

Create directories with names similar to the following, and specify the correct owner, group, and permissions for them:

- The Oracle base directory

- An optional Oracle data file directory

The Oracle base directory must have 3 GB of free disk space, or 4 GB of free disk space if you choose not to create a separate Oracle data file directory.

Note:

If you do not want to create a separate Oracle data file directory, then you can install the data files in a subdirectory of the Oracle base directory. However, this is not recommended for production databases.

To create the Oracle base directory:

1. Enter the following command to display information about all mounted file systems:

# df -k

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

2. From the display, identify either one or two file systems that meet the disk space requirements mentioned earlier in this section.

3. Note the name of the mount point directory for each file system that you identified.

4. 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/
# chown -R oracle:oinstall /mount_point/app/
# chmod -R 775 /mount_point/app/

For example:

# mkdir -p /u01/app/
# chown -R oracle:oinstall /u01/app/
# chmod -R 775 /u01/app/

8 Configuring the oracle User's Environment

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:

1. Start a new terminal session, for example, an X terminal (xterm).

2. Enter the following command to ensure that X Window applications can display on this system:

$ xhost fully_qualified_remote_host_name

For example:

$ xhost somehost.us.example.com

3. If you are not logged in to the system where you want to install the software, then log in to that system as the oracle user.

4. If you are not logged in as the oracle user, then switch user to oracle:

$ su - oracle

5. To determine the default shell for the oracle user, enter the following command:

$ echo $SHELL

6. To run the shell startup script, enter one of the following commands:

- Bash shell:

$ . ./.bash_profile

- Bourne or Korn shell:

$ . ./.profile

- C shell:

% source ./.login

7. If you are not installing the software on the local computer, then run the following command on the remote computer to set the DISPLAY variable:

- Bourne, Bash or Korn shell:

$ export DISPLAY=local_host:0.0

- C shell:

% setenv DISPLAY local_host:0.0

In this example, local_host is the host name or IP address of the local computer to use to display Oracle Universal Installer.

Run the following command on the remote computer to check if the shell and the DISPLAY environmental variable are set correctly:

echo $SHELL
echo $DISPLAY

Now to enable X applications, run the following commands on the local computer:

$ xhost + fully_qualified_remote_host_name

To verify that X applications display is set properly, run a X11 based program that comes with the operating system such as xclock:

$ xclock

In this example, you can find xclock at /usr/X11R6/bin/xclocks. If the DISPLAY variable is set properly, then you can see xclock on your computer screen.

See Also:

PC-X Server or operating system vendor documents for further assistance

8. If you determined that the /tmp directory has less than 1 GB of free disk space, then identify a file system with at least 1 GB of free space and set the TMP and TMPDIR environment variables to specify a temporary directory on this file system:

1. To determine the free disk space on each mounted file system use the following command:

# df -h /tmp

2. 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:

$ sudo mkdir /mount_point/tmp
$ sudo chmod a+wr /mount_point/tmp
# exit

3. 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

9. Enter commands similar to the following to set the ORACLE_BASE and ORACLE_SID environment variables:

- Bourne, Bash, or Korn shell:

$ ORACLE_BASE=/u01/app/oracle
$ ORACLE_SID=sales
$ export ORACLE_BASE ORACLE_SID

- C shell:

% setenv ORACLE_BASE /u01/app/oracle
% setenv ORACLE_SID sales

In this example, /u01/app/oracle is the Oracle base directory that you created or identified earlier and sales is the database name (typically no more than five characters).

10. 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

Note:

If the ORACLE_HOME environment variable is set, then Oracle Universal Installer uses the value that it specifies as the default path for the Oracle home directory. However, if you set the ORACLE_BASE environment variable, then Oracle recommends that you unset the ORACLE_HOME environment variable and choose the default path suggested by Oracle Universal Installer.

9 Mounting the Product Disc

On most Linux systems, the disk mounts automatically when you insert it into the installation media. If the disk does not mount automatically, then follow these steps to mount it:

1. Enter a command similar to the following to eject the currently mounted disc, then remove it from the drive:

- Asianux, Oracle Linux, and Red Hat Enterprise Linux:

$ sudo eject /mnt/dvd

- SUSE Linux Enterprise Server:

# eject /media/dvd

In these examples, /mnt/dvd and /media/dvd are the mount point directories for the disc drive.

2. Insert the DVD into the disc drive.

3. To verify that the disc mounted automatically, enter a command similar to the following:

- Asianux, Oracle Linux, and Red Hat Enterprise Linux:

# ls /mnt/dvd

- SUSE Linux Enterprise Server:

# ls /media/dvd

4. If this command fails to display the contents of the disc, then enter a command similar to the following:

- Asianux, Oracle Linux, and Red Hat Enterprise Linux:

# mount -t iso9660 /dev/dvd /mnt/dvd

- SUSE Linux Enterprise Server:

# mount -t iso9660 /dev/dvd /media/dvd

In these examples, /mnt/dvd and /media/dvd are the mount point directories for the disc drive.

10 Installing Oracle Database

After configuring the oracle user's environment, start Oracle Universal Installer and install Oracle Database as follows:

1. To start Oracle Universal Installer, enter the following command:

$ /mount_point/db/runInstaller

If Oracle Universal Installer does not start, then refer to Oracle Database Installation Guide for Linux for information about how to troubleshoot X Window display problems.
