The guide provides a walk through of installing Oracle Enterprise Manager Grid Control 10g Release 3 on commodity hardware for the purpose of evaluation.  If you are new to Linux and/or Oracle, this guide is for you. It starts with the basics and walks you through an installation of Oracle Enterprise Manager Grid Control 10g Release 3 from the bare metal up.

This guide will take the approach of offering the easiest paths, with the fewest number of steps for accomplishing a task.  This approach often means making configuration choices that would be inappropriate for anything other than an evaluation.  For that reason, this guide is not appropriate for building production-quality environments, nor does it reflect best practices.

The  Linux distributions certified for Oracle Enterprise Manager Grid Control 10g Release 3 are:

• Red Hat Enterprise Linux  4 (RHEL4)
• Novell SUSE Linux Enterprise Server 9 (SLES9)

We will cover both of these distributions. Although Oracle Enterprise Linux is not explicitly covered here, the steps involved should mirror those required for RHEL4.

This guide is divided into three parts: Part I covers the installation of the Linux operating system, Part II covers configuring Linux for Oracle and Part III discusses the essentials of installing the Oracle Enterprise Manager Grid Control. 

Hardware used for this walk through:

• 2.5GHz P4 CPU
• 2GB of RAM
• Four SCSI disk drives (1 x 9GB + 3 x 36GB)
• One Gig-E (1000 Base-T) Ethernet adapter

Your hardware does not have to match this in order to use this guide.  All that is necessary for a basic install is a single CPU, 2GB of RAM, a network interface controller (NIC), and one disk drive (IDE, SCSI, or FireWire) with at least 4.5GB of free space.

Now, let's walk through the process of installing the Linux operating system on a server. The instructions assume a fresh install of Linux (as opposed to an upgrade), that the server will be dedicated to Oracle, and that no other operating systems or data are on the server.

Oracle Enterprise Manager Grid Control 10g Release 3 is certified to run on Red Hat Enterprise Linux 4 (ES or AS) Update 1 or later. (Free evaluation copies of RHEL4 are available for download.) If you have update CDs, you can use the boot CD from the update instead of the boot CD from the base release to automatically apply all updates during the installation. All updates from Red Hat are supported by Oracle.

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.
   • 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.
   • Select Enter to continue with a graphical install on the console. (For other installation methods and options, refer to the Red Hat Installation Guide.)
   • The installer scans your hardware, briefly displays the Red Hat splash screen, and then begins a series of screen prompts.
3. Language Selection
   • Accept the default.
4. Keyboard Configuration
   • Accept the default.
5. Welcome Screen
   • Click on Next.
6. Disk Partitioning Setup
   • 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 first disk (/dev/sda) will hold all Linux and Oracle software and contains the following partitions:
     - 100MB /boot partition
     -2,048MB 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.
     
     One of the 36GB disks (/dev/sdb) was configured with a single partition containing an ext3 file system mounted as /u01.  This file system will be used for the Oracle software and database.

7. Boot Loader Configuration
   • Accept the default.
8. Network Configuration
   • It is usually best to configure servers with a static IP address. To do so, click on Edit .
   • 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 .
   • In the Hostname box, select manually and enter the hostname.
   • In the Miscellaneous Settings box, enter the remaining network settings.
9. Firewall Configuration
   • For the purposes of this walk-through, no firewall is configured. Select No firewall
   • Select Disabled on the "Enable SELinux" drop down list. 
   • Click on Proceed when the "Warning - No Firewall" window appears.
10. Additional Language Support
    • Accept the default.
11. Time Zone Selection
    • 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
    
    • Enter a password for root, and enter it again to confirm.
13. Package Installation Defaults
    • Select Customize software packages to be installed.
14. Package Group Selection
    • Select only the package sets shown here and leave all others unselected. 
    • Desktop
    • X Window System

    • Miscellaneous
    • Do not select anything in this group.
    • Click on Next to proceed.
15. Installing Packages
    • Software will be copied to the hard disk and installed. Change disks as prompted.
16. Congratulations
    • Remove the installation media from the system, and click on Reboot .
17. The system automatically reboots and presents a new welcome screen.
    • Click on Next.
18. License Agreement
    • Read the license agreement. If you agree to the terms, select Yes, I agree to the License Agreement and click on Next.
19. Date and Time
    • Set the Date and Time.
    • If you want to use an NTP server (recommended), select Enable Network Time Protocol and enter the name of the NTP server.
20. Display
    • Accept the defaults or change as required.
21. Red Hat Login
• Enter your Red Hat Network login and password or create a new one.
22. System User
• Create an account for yourself.
• Do not create an account for oracle at this time. Creating the oracle account is covered later in this section.
23. Additional CDs
• Click on Next.
24. Finish Setup
• Click on Next.
25. A graphical login screen appears.
26. Congratulations! Your RHEL4 software is now installed.

Part II: Configuring Linux for Oracle

Now that the Linux software is installed, you need to configure it for Oracle. This section walks through the steps required to configure Linux for Oracle Enterprise Manager Grid Control 10g Release 3.

Verifying System Requirements

To verify that your system meets the minimum requirements for a Oracle Enterprise Manager Grid Control 10g Release 3, log in as root and run the commands below.

grep MemTotal /proc/meminfo
grep SwapTotal /proc/meminfo

Ex:
# grep MemTotal /proc/meminfo
MemTotal: 2083256 kB
# grep SwapTotal /proc/meminfo
SwapTotal: 4194304 kB

The minimum RAM required is 2GB, and the minimum required swap space is 4GB. 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 4.5GB of available disk space for the Oracle Enterprise Manager Grid Control 10g Release 3 software. 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% /boot
/dev/sdb1 36G 232M 99% /u01

The example shows that the /tmp directory does not have its own filesystem. (It's part of the root filesystem for this guide.)

Configuring the Linux Kernel Parameters

Oracle Enterprise Manager 10g Release 3 requires the kernel parameter settings shown below. The values given are minimums, so if your system uses a larger value, don't change it.

Red Hat Enterprise Linux 4

kernel.sem = 250 32000 100 128
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.shmall = 2097152
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=262144
net.core.wmem_default=262144
net.core.rmem_max=262144
net.core.wmem_max=262144

SUSE Linux Enterprise Server 9

kernel.sem = 250 32000 100 128
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.shmall = 2097152
fs.file-max = 65536

Note:  The Oracle supplied documentation indicates that kernel.shmmin should be set to 1 and that kernel.shmseg should be set to 10.  The shmmin and shmseg parameters cannot be changed in /etc/sysctl.conf in SLES9 and are built into the kernel.  If you are using a pre-built kernel provided by Novell, the default values for these parameters are adequate.  See MetaLink Note: 345052.1 for more information.

If you have just installed Linux, the kernel parameters will all have their default values and you can just cut and paste the following commands while logged in as root. 

Red Hat Enterprise Linux 4

cat >> /etc/sysctl.conf <<EOF
kernel.sem = 250 32000 100 128

net.core.rmem_default=262144
net.core.wmem_default=262144
net.core.rmem_max=262144
net.core.wmem_max=262144
EOF
/sbin/sysctl -p

Ex:

kernel.core_uses_pid = 1
kernel.sem = 250 32000 100 128
kernel.shmmax = 536870912

net.core.wmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_max = 262144

SUSE Linux Enterprise Server 9

cat >> /etc/sysctl.conf <<EOF
kernel.sem = 250 32000 100 128
kernel.shmmax = 2147483648

kernel.shmall = 2097152
fs.file-max = 65536
EOF
/sbin/sysctl -p
/sbin/chkconfig boot.sysctl on

Red Hat and SUSE

Run the following commands as root to verify your settings:

/sbin/sysctl -a | grep shm
/sbin/sysctl -a | grep sem
/sbin/sysctl -a | grep file-max
/sbin/sysctl -a | grep ip_local_port_range
/sbin/sysctl -a | grep rmem_default
/sbin/sysctl -a | grep rmem_max
/sbin/sysctl -a | grep wmem_default
/sbin/sysctl -a | grep wmem_max

Ex:
# /sbin/sysctl -a | grep shm
kernel.shmmni = 4096
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shm-use-bigpages = 0
# /sbin/sysctl -a | grep sem
kernel.sem = 250 32000 100 128
# /sbin/sysctl -a | grep file-max
fs.file-max = 65536
# /sbin/sysctl -a | grep ip_local_port_range
net.ipv4.ip_local_port_range = 1024 65000
# /sbin/sysctl -a | grep rmem_default
net.core.rmem_default = 262144
# /sbin/sysctl -a | grep rmem_max
net.core.rmem_max = 262144
# /sbin/sysctl -a | grep wmem_default
net.core.wmem_default = 262144
# /sbin/sysctl -a | grep wmem_max
net.core.wmem_max = 262144

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 Enterprise Manager Grid Control 10g Release 3 software. The user account will be called oracle, and the group will be oinstall. Execute the following commands as root:

/usr/sbin/groupadd oinstall
/usr/sbin/useradd -m -g oinstall oracle
id oracle

Ex:
# /usr/sbin/groupadd oinstall
# /usr/sbin/useradd -m -g oinstall oracle
# id oracle
uid=501(oracle) gid=502(oinstall) groups=502(oinstall)

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.

Create Directories

Now create directories to store the Oracle Enterprise Manager Grid Control 10g Release 3 software and its 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

Setting Shell Limits for the oracle User

Oracle recommends setting limits on the number of processes and open files each Linux account may use. To make these changes, cut and paste the following commands as root:

cat >> /etc/security/limits.conf <<EOF
* soft nproc 2047
* hard nproc 16384
* soft nofile 2048
* hard nofile 65536
EOF

cat >> /etc/pam.d/login <<EOF
session required /lib/security/pam_limits.so
EOF

For RHEL4, use the following:

cat >> /etc/profile <<EOF
if [ \$USER = "oracle" ]; then 
 if [ \$SHELL = "/bin/ksh" ]; then
 ulimit -p 16384
 ulimit -n 65536
 else
 ulimit -u 16384 -n 65536
 fi
 umask 022
fi
EOF

cat >> /etc/csh.login <<EOF
if ( \$USER == "oracle" ) then
 limit maxproc 16384
 limit descriptors 65536
 umask 022
endif
EOF

For SLES 9, use the following:

cat >> /etc/profile.local <<EOF
if [ \$USER = "oracle" ]; then 
 if [ \$SHELL = "/bin/ksh" ]; then
 ulimit -p 16384
 ulimit -n 65536
 else
 ulimit -u 16384 -n 65536
 fi
 umask 022
fi
EOF

cat >> /etc/csh.login.local <<EOF
if ( \$USER == "oracle" ) then
 limit maxproc 16384
 limit descriptors 65536
 umask 022
endif
EOF

Installing Oracle Enterprise Manager Grid Control 10g Release 3 is a two step process.  First, install OEM Grid Control 10g Release 2, then upgrade Release 2 to Release 3.  Please note that there is no way to directly install Release 3.  

Both OEM Grid Control 10g Release 2 and the Release 3 upgrade software for Linux can be downloaded from OTN. Oracle offers a development and testing license free of charge. However, no support is provided and the license does not permit production use. A full description of the license agreement is available on OTN.

The easiest way to make the Oracle Enterprise Manager Grid Control 10g Release 3 distribution media available on your server is to download them directly to the server.

Use the graphical login to log in as oracle.

Create a directory to contain the Oracle Enterprise Manager Grid Control 10g Release 2 distribution:

mkdir grid10gR2

Download Oracle Enterprise Manager Grid Control 10g Release 2 from OTN, then unzip and extract the files:

cd grid10gR2
unzip Linux_Grid_Control_full_102010_disk1.zip
unzip Linux_Grid_Control_full_102010_disk2.zip
unzip Linux_Grid_Control_full_102010_disk3.zip

Next, create a directory to contain the Oracle Enterprise Manager Grid Control 10g Release 3 upgrade distribution:

After downloading Oracle Enterprise Manager Grid Control 10g Release 3 from OTN, unzip and extract the file:

Install the Enterprise Manager Grid Control Software

Log in using the oracle account.

For SLES9 only, set the LD_ASSUME_KERNEL environment variable to 2.4.21
Ex:
LD_ASSUME_KERNEL=2.4.21; export LD_ASSUME_KERNEL

Ex:
$ cd grid10gR2

1. Repository
   ORACLE_HOME=/u01/app/oracle/db10g
   
2. Oracle Management Service (OMS)
   ORACLE_HOME=/u01/app/oracle/oms10g
3. Management Agent
   ORACLE_HOME=/u01/app/oracle/agent10g
   

The OEM Grid Control 10g Release 3 pach must be applied to both the OMS and Agent components.  The repository is automatically upgraded when the OMS is upgraded.

Before upgrading to OEM Grid Control 10g Release 3, stop OEM Grid Control Release 2 using the following command as root.  This will stop all three components (repository, OMS, and agent.:
# /etc/init.d/gcstartup stop

Change directory to the location where you extracted the Oracle Enterprise Manager Grid Control 10g Release 3 software.
$ cd grid10gR3

Before upgrading the OMS to Release 3, the database requires a patch. Install the patch using the OPatch utility as shown in the example below.

Unzip the database patch.
$ unzip p4329444_10104_LINUX.zip

Change directories to the patch directory.
$ cd 4329444

Set the ORACLE_HOME environment variable for the database.
$ export ORACLE_HOME=/u01/app/oracle/db10g

Run the OPatch utility to apply the patch.
$ $ORACLE_HOME/OPatch/opatch apply
