Installing Linux
RHEL4
Oracle Database 10g Release 2 is certified to run the base release of RHEL4 (Advanced Server and
The easiest and fastest way to apply the updates for a fresh install of Linux is to perform the install by using the update CDs. If Linux is already installed or you don't have the updates on CDs, they can be applied through RHN. Because this guide is designed for a fresh Linux install, you'll use the update CDs.
1. Boot the server using the first CD.
o You may need to change your BIOS settings to allow booting from the CD.
2. The boot screen appears with the boot: prompt at the bottom of the screen.
o Select Enter to continue with a graphical install on the console.
o The installer scans your hardware, briefly displays the Red Hat splash screen, and then begins a series of screen prompts.
3. Language Selection
o Accept the default.
4. Keyboard Configuration
o Accept the default.
5. Welcome Screen
o Click on Next.
6. Disk Partitioning Setup
o A thorough treatment of disk partitioning is beyond the scope of this guide, which assumes that you are familiar with disk partitioning methods.
(WARNING: Improperly partitioning a disk is one of the surest and fastest ways to wipe out everything on your hard disk. If you are unsure how to proceed, stop and get help, or you will risk losing data!)
This guide uses the following partitioning scheme, with ext3 for each filesystem:
The 9GB disk on the first controller (/dev/sda) will hold all Linux and Oracle software and contains the following partitions:
- 100MB /boot partition
-1,500MB swap partition—Set this to at least twice the amount of RAM in the system but to no more than 2GB. (Thirty-two-bit systems do not support swap files larger than 2GB.) If you need more than 2GB of swap space, create multiple swap partitions.
-7,150MB root partition—This partition will be used for everything, including /usr, /tmp, /var, /opt, /home, and more. This approach is purely to simplify installation for the purposes of this guide. A more robust partitioning scheme would separate these directories onto separate filesystems.
7. Boot Loader Configuration
o Accept the default.
8. Network Configuration
o It is usually best to configure database servers with a static IP address. To do so, click on Edit .
o A pop-up window appears. Uncheck the Configure using DHCP box, and enter the IP Address and Netmask for the server. Be sure that Activate on boot is checked, and click on OK .
o In the Hostname box, select manually and enter the hostname.
o In the Miscellaneous Settings box, enter the remaining network settings.
9. Firewall Configuration
o For the purposes of this walk-through, no firewall is configured. Select No firewall
o Select Disabled on the "Enable SELinux" drop down list.
o Click on Proceed when the "Warning - No Firewall" window appears.
10. Additional Language Support
o Accept the default.
11. Time Zone Selection
o Choose the time settings that are appropriate for your area. Setting the system clock to UTC is usually a good practice for servers. To do so, click on System clock uses UTC.
12. Set Root Password
o Enter a password for root, and enter it again to confirm.
13. Package Installation Defaults
o Select Customize software packages to be installed.
14. Package Group Selection
o Select only the package sets shown here and leave all others unselected.

To verify that your system meets the minimum requirements for an Oracle Database 10g Release 2 database, log in as root and run the commands below.
To check the amount of RAM and swap space available, run this:
grep MemTotal /proc/meminfo
grep SwapTotal /proc/meminfo
Ex:
# grep MemTotal /proc/meminfo
MemTotal: 1034680 kB
# grep SwapTotal /proc/meminfo
SwapTotal: 1534196 kBThe minimum RAM required is 1024MB, and the minimum required swap space is 1GB. Swap space should be twice the amount of RAM for systems with 2GB of RAM or less and between one and two times the amount of RAM for systems with more than 2GB.
You also need 2.5GB of available disk space for the Oracle Database 10g Release 2 software and another 1.2GB for the database. The /tmp directory needs at least 400MB of free space. To check the available disk space on your system, run the following command:
df -h
Ex:
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 6.8G 1.3G 5.2G 20% /
/dev/sda1 99M 17M 77M 18% /bootThe example shows that the /tmp directory does not have its own filesystem. (It's part of the root filesystem for this guide.) With 5.2 GB available, the root filesystem has just enough space for the installation (2.5 + 1.2 + 0.4 = 4.1GB) with a little room left over.
Create the Oracle Groups and User Account
Next, create the Linux groups and user account that will be used to install and maintain the Oracle Database 10g Release 2 software. The user account will be called oracle, and the groups will be oinstall and dba. Execute the following commands as root:
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -m -g oinstall -G dba oracle
id oracle
Ex:
# /usr/sbin/groupadd oinstall
# /usr/sbin/groupadd dba
# /usr/sbin/useradd -m -g oinstall -G dba oracle
# id oracle
uid=501(oracle) gid=502(oinstall) groups=502(oinstall),503(dba)Set the password on the oracle account:
passwd oracle
Ex:
# passwd oracle
Changing password for user oracle.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.Now create directories to store the Oracle Database 10g Release 2 software and the database files.
The following assumes that the directories are being created in the root filesystem. This is done for the sake of simplicity and is not recommended as a general practice. These directories would normally be created as separate filesystems.
Issue the following commands as root:
mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle
Ex:
# mkdir -p /u01/app/oracle
# chown -R oracle:oinstall /u01/app/oracle
# chmod -R 775 /u01/app/oracleConfiguring the Linux Kernel Parameters

Partition the Disks
In order to use either file systems or ASM, you must have unused disk partitions available. This section describes how to create the partitions that will be used for new file systems and for ASM.
WARNING: Improperly partitioning a disk is one of the surest and fastest ways to wipe out everything on your hard disk. If you are unsure how to proceed, stop and get help, or you will risk losing data.
This example uses /dev/sdb (an empty SCSI disk with no existing partitions) to create a single partition for the entire disk (36 GB).
Ex:
# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 4427.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p

Device Boot Start End Blocks Id System
/dev/sdb1 * 1 4427 35559846 83 LinuxRepeat the above steps for each disk to be partitioned. The following section on Filesystems uses a single disk partition, /dev/sdb1. The ASM example uses three partitions on three disks: /dev/sdb1, /dev/sdc1, and /dev/sdd1
Filesystems are the most widely used means of storing data file, redo logs, and control files for Oracle databases. Filesystems are easy to implement and require no third-party software to administer.
In most cases, filesystems are created during the initial installation of Linux. However, there are times when a new filesystem must be created after the initial installation, such as when a new disk drive is being installed.
This section describes building a new filesystem and using it in an Oracle database. Unless otherwise noted, all commands must be run as root.
Create the Filesystem
Use ext3 to create this new filesystem. Other filesystems work just as well, but ext3 offers the fastest recovery time in the event of a system crash.
Ex:
# mke2fs -j /dev/sdb1
mke2fs 1.26 (3-Feb-2002)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
4447744 inodes, 8889961 blocks
444498 blocks (5.00%) reserved for the super user
First data block=0
272 block groups
32768 blocks per group, 32768 fragments per group
16352 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632,
2654208, 4096000, 7962624
Writing inode tables: done
Creating journal (8192 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 23 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.Create the Mount Point
A filesystem must have a mount point, which is simply an empty directory where the new filesystem "attaches" to the system's directory tree.
Because you have already created the /u01 directory in Part I, use /u02 for this example.
Ex:
# mkdir /u02Add the New Filesystem to /etc/fstab
So that the new filesystem will be mounted automatically when the system boots, you need to add a line to the /etc/fstab file that describes the new filesystem and where to mount it. Add a line similar to the one below to /etc/fstab, using a text editor.
/dev/sdb1 /u02 ext3 defaults 1 1Mount the New Filesystem
Mounting the filesystem makes it available for use. Until the filesystem is mounted, files cannot be stored in it. Use the following commands to mount the filesystem and verify that it is available.
mount /u02
df -h /u02
Ex:
# mount /u02
# df -h /u02
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 33G 33M 31G 1% /u02Create Oracle Directories and Set Permissions
Now you create a directory to store your Oracle files. The directory name used in the example follows the OFA standard naming convention for a database with ORACLE_SID=demo1.
mkdir -p /u02/oradata/demo1
chown -R oracle:oinstall /u02/oradata
chmod -R 775 /u02/oradataCreate a New Tablespace in the New Filesystem
The new filesystem is ready for use. Next you create a new tablespace in the filesystem to store your database objects. Connect to the database as the SYSTEM user, and execute the CREATE TABLESPACE statement, specifying the data file in the new filesystem.
Ex:

The listener accepts connection requests from clients and creates connections to the database once the credentials have been authenticated. Before you can use OEM or iSQL*Plus, the listener must be up.
$ lsnrctl start
$ lsnrctl stopStarting and Stopping the Database:
