11g Fusion Middleware Install Walkthrough – Part 1 Before you Install.

The 11g Fusion Middleware installation can seem daunting when you first look at the documentation as compared to 10g.  With 10g it was pretty simple, install an infrastructure tier and then an application tier, all from the same installation media.

With 11g there are many components to download, such as Weblogic, Portal, SOA, Repository Creation Utilities, Database Server, SSO, etc.   So I thought I would document how I installed it for two reasons.. The main one being that when I have to install this beast again for a TEST environment I know exactly how I set up DEV.   The second reason is that hopefully this will benefit some of you trying to install this yourselves.

As always when sharing information, if you see any errors/mis-steps, etc feel free to leave a comment.   There is alot of information to sift through during the install so I can’t guarantee I have captured all of the steps, so if I have missed something please let me know.

Part 1 includes links to resources and a brief overview of the system and memory requirements.

Part 2 will cover installing the database tier which consists of the database and OID.

Part 3 will cover installing SSO on the application tier.

Part 4 will cover installing SOA and Portal on the application tier.
------------
SCENARIO: Installing full Fusion Middleware Stack on 64bit Oracle Enterprise Linux consisting of two tiers:

Database Tier:
Oracle Weblogic Server
Oracle Database 11g (11.1.0.7+)
Oracle Identity Management

Application/Middle Tier:
Oracle Weblogic Server
Oracle SOA Suite
Oracle Single Sign-On
Oracle Portal, Forms, Reports

URLS:

Below are some URLS which contain useful information such as the documentation, certification and requirements information and release notes.
*Important, read the release notes for the platform you are using before the install. A couple of key issues that you may encounter from this document for x86-64:

Installation and Configuration
Configuration Issues and Workarounds
 Documentation Errata
Known Issues for JDeveloper and ADF 11g (11.1.1.1.0)
Oracle 11gR2
OID (SSO Component)
  • Subject: Oracle Identity Management 10g (10.1.4.0.1) Release Notes Addendum   Doc ID: 465847.1

 

Server Setup

I’m assuming you already have a 64bit version of Oracle Enterprise Linux installed on two servers.   OEL 5.3 has alot of the pre-reqs required already installed, so from a server perspective there aren’t many changes.

Required Packages: OEL 5.3 for X86_64:

Most packages are installed by default with OEL 5.3. Those that need to be installed:

openmotif22-2.2.3 (for Oracle Reports Server)
openmotif-2.2.3 (for Oracle Reports Server)
gdbm (Application Server)

If you don’t have a valid CSI from Oracle Support, setup the public yum repository.

Install the missing packages using yum. Pass the following package names to yum install, see example below.
· unixODBC.i386
· unixODBC-devel.i386
· openmotif22.x86_64
· openmotif.x86_64
· libaio-devel.i386
· gdbm

Installation example for one package:


[root@dbtier yum.repos.d]# yum install libaio-devel.i386

Loaded plugins: security

Post-Install Steps for GDBM


After you install GDBM create the following symbolic link:


[root@myserver ~]# ln -s /usr/lib/libgdbm.so.2.0.0 /usr/lib/libdb.so.2

Supported JVMs
Sun 1.6.0_11+

Kernel Parameters

Only changes required on top of OEL5.3:

fs.file-max = 6815744
net.core.wmem_max = 1048576
net.ipv4.ip_local_port_range = 1024 65500
net.core.rmem_default = 4194304



Execute sysctl –p to load the settings or reboot.

Environment Settings

· Add or edit the following line in the /etc/pam.d/login file, if it does not already exist:


session    required     pam_limits.so

Software to Download

I was going to capture the links for all the packages that you will need to download.  But as I was in the process up writing up this guide the Oracle Technology Network downloads page has been updated with the latest version 11.1.1.2
