Purpose

In this tutorial, you learn how to install Oracle Enterprise Manager Grid Control 11g Release 1 (11.1.0.1.0) Linux x86.

Time to Complete

Approximately 2.5 hours.

Overview

Earlier releases of Oracle Enterprise Manager Grid Control were installed in a single step using Oracle Universal Installer. With the release of Oracle Enterprise Manager Grid Control 11g Release 1 (11.1.0.1.0) installing Oracle Enterprise Manager Grid Control is a three step process requiring the installation of Oracle WebLogic Server and Oracle Database prior to installing Grid Control.

Scenario

In this tutorial, you install Oracle WebLogic Server 11g Release 1 (10.3.2) Linux x86, Oracle Database 11g Release 2 (11.2.0.1.0) Linux x86, and Oracle Enterprise Manager Grid Control 11g Release 1 (11.1.0.1.0) Linux x86.

Software Requirements

The following is a list of software requirements:

Download Oracle Enterprise Manager Grid Control 11g Release 1 (11.1.0.1.0) Linux x86 from OTN at this link
Download Oracle WebLogic Server 11g Release 1 (10.3.2) Linux x86 from OTN at this link
Oracle Database 11g Release 2 (11.2.0.1.0) Linux x86 from OTN at this link

Prerequisites

Before starting this tutorial, you should:

Have a server with 4G or more RAM
Complete a default install of Oracle Enterprise Linux 5.X (this example uses 5.4) with the oracle-validated RPM installed
Have 7G of free disk space for the installation software
Have 14G of free space for installing the software

Note: Screen captures for this tutorial were taken in Oracle Enterprise Linux 5.4 with a Gnome 2.16 Desktop.

Configuring the Operating System

Installing the oracle-validated RPM installs RPMs required for an Oracle installation as well as creates the operating system user oracle. The lesson uses operating system user oracle to install all the software.

Before installing the software the operating system must be configured. To configure the operating system perform the following steps as operating system user root.

	Configuring the Operating System
	Staging Software
	Installation Information

Configuring the Operating System

1 .	As root, in a terminal, perform these steps to configure the operating system in preparation for the software installations. a. Add operating system group oper. b. Modify operating system user oracle by adding group oper. c. Assign a password to operating system user oracle. d. Create directory /u01/app. Assign ownership root:oinstall and permission 775. e. Create directory /u01/app/oracle. Assign ownership oracle:oinstall. Operating system commands: groupadd oper usermod -g oinstall -G dba,oper oracle passwd oracle mkdir /u01/app chown root:oinstall /u01/app chmod 775 /u01/app mkdir /u01/app/oracle chown oracle:oinstall /u01/app/oracle

1 .

As root, in a terminal, perform these steps to configure the operating system in preparation for the software installations.

a. Add operating system group oper.

b. Modify operating system user oracle by adding group oper.

c. Assign a password to operating system user oracle.

d. Create directory /u01/app. Assign ownership root:oinstall and permission 775.

e. Create directory /u01/app/oracle. Assign ownership oracle:oinstall.

Operating system commands:

groupadd oper
usermod -g oinstall -G dba,oper oracle
passwd oracle
mkdir /u01/app
chown root:oinstall /u01/app
chmod 775 /u01/app
mkdir /u01/app/oracle
chown oracle:oinstall /u01/app/oracle

Staging Software

2 .	The installation software for this lesson is staged in directory /stage.

Installation Information

3 .

The software will be installed using the follow homes:

Database:	/u01/app/oracle/database/11.2.0/dbhome_1
WebLogic:	/u01/app/oracle/middleware
EMGC:	/u01/app/oracle/gc_inst

The lesson uses these values:

Host:	host01
Domain:	example.com
Database SID:	emrep
Global Database Name:	emrep.example.com

Use your host name and domain name.
Any valid database SID can be used.
When passwords are required, choose a strong password. Do not use the passwords provided in the lesson.

Installing Oracle WebLogic Server 11g Release 1 (10.3.2) Linux x86

4 .	Connect as operating system user oracle in an X session.
5 .	Execute the installer for Oracle WebLogic Server 11g Release 1 (10.3.2) Linux x86. ls -al /stage/wls cd /stage/wls ./wls1032_linux32.bin
6 .	Click Next.
7 .	Set the value of Middleware Home Directory to: /u01/app/oracle/middleware Click Next.
8 .	Enter your e-mail address and My Oracle Support Password. Click Next. If you choose to leave the fields blank, you will receive a pop up after clicking Next. Click Yes, to continue.
9 .	Click Next.
10 .	Click Next.
11 .	Click Next.
12 .	Wait for the installation to complete.
13 .	After the installation completes, uncheck Run Quickstart. Click Done.

32 .	Click Close.

Removing Enterprise Manager Database Control

Creating a database using a Database Configuration Assistant template, as is done when choosing to create a database in the Oracle Universal Installer, creates a database containing an Enterprise Manger Database Control repository. The repository contains a subset of the Enterprise Manager Grid Control functionality. Before Enterprise Manager Grid Control can use the database, the Enterprise Manager Database Control repository must be dropped and the configuration files removed.

33 .	Set the environment by souring oraenv located in /usr/local/bin. Execute the command to remove Enterprise Manager Database Control. . oraenv emrep emca -deconfig dbcontrol db -repos drop -HOST host01.example.com -PORT 1521 -SID emrep -SYS_PWD oracle_4U -SYSMAN_PWD oracle_4U -DBSNMP_PWD oracle_4U Y

Configuring the Database for an Enterprise Manager Grid Control Installation

Enterprise Manager Grid Control database repository requirements exceed the default configuration from the Database Configuration Assistant template. Perform the following to meet the requirements.

34 .	An Enterprise Manager Grid Control 11g Release 1 (11.1.0.1.0) database repository requires: session_cached_cursors to be set to 200 or more log_buffer set to 10485760 or more processes set to 500 or more undo tablespace size to be 200M or greater The first three changes require the database to be bounced for the changes to take effect. sqlplus /nolog connect / as sysdba alter system set session_cached_cursors=200 scope=spfile; alter system set log_buffer=10485760 scope=spfile; alter system set processes=500 scope=spfile; alter database datafile '/u01/app/oracle/database/oradata/emrep/undotbs01.dbf' resize 250M; shutdown immediate startup exit

An Enterprise Manager Grid Control 11g Release 1 (11.1.0.1.0) database repository requires:

session_cached_cursors to be set to 200 or more
log_buffer set to 10485760 or more
processes set to 500 or more
undo tablespace size to be 200M or greater

The first three changes require the database to be bounced for the changes to take effect.
