Installing Oracle Collaboration Suite

Few post ago i had discussed about the Oracle Collaboration suite, In today’s post i will discuss the installation of Oracle Collaboration Suite and Collaboration Applications.

System Environment
Operation System: Redhat Linux AS 4
Oracle Collaboration Suite Version: 10.1.2

Though we can install the Applications and the infrastructure for Oracle Collaboration Suite together for the ease of  management and understanding i had decided to go in for a separate installation.

Operating System Users
As a first set we will create two users one for holding the Infrastructure of Collaboration Suite and the other for holding  the collaboration suite middle tier applications.

# useradd -g dba -d /u03/ocsin ocsin
# useradd -g dba -d /u03/ocsmi ocsmi

Pre Requisite Checks

Memory requirement
The Oracle Collaboration Suite Both Infrastructure and Application would require a minimum of a 2 GB memory. You must make  sure of this.

grep MemTotal /proc/meminfo
MemTotal:      8312720 kB

Temp Space
Ensure you have at least 250 MB free space in your tmperory directory

# df -k /tmp

Swap Space.
Ensure that at least 1.5 GB of unused swap space is available before proceeding with the installation.

# free -m
             total       used       free     shared    buffers     cached
Mem:          8117       8084         33          0         23       7115
-/+ buffers/cache:        944       7173
Swap:         1601          0       1601

Staring The Installation
We first start the infrastructure installation as the infrastructure user ocsin

#su - ocsin
$ ./runInstaller

The first screen you see presents you with two choices, a basic installation and an advanced installation, i chose the advanced installation as it gives you more flexibility in terms of your installation and products you choose.




In the next screen you specify the ORACLE_HOME for your OCS infrastructure



The next screen gives an options to install the infrastructure and Application together or Infrastructure Only or Applications only. I choose the infrastructure only option.



This screen allows us to choose the type of Collaboration Suite Infrastructure we want to install. The choices her are IM and OCS DB, just the OCS DB, Just IM and convert an existing DB into an OCS DB. I have selected IM and OCS DB here.



The installer now does a pre requisite check for before proceeding with the installation.



Since OCS can be installed with support for multiple languages, this screen allows us to choose the additional languages which we wish to install with OCS.



The OCS infrastructure like the 10g Application Server infrastructure uses the 1521 port for its listener, it is not allowed to change this at the time of installation. You can however choose to share the listener in case 1521 is used by another listener.



The next screen displays a list of services that the OUI will configure and start for you as a part of the installation.



This screen specifies the namespace that will be used for your Oracle Internet Directory, You can change this if you wish.



Now you can specify whether to have automatic port selection or change it. For static ports you require a staticports.ini file which must be specified at the time of starting your OUI



This screen allows you to create the password for the orclguest user.



In this screen you specify the name for your database and the location you want to place your data files.



Here you specify the password for your other oracle schemas.



In this screen you specify the instance name for you infrastructure database and the passwords for the super user.

This screen displays the components the OUI is going to start the installation with.

After this the installer will start the installation, at the end of the installation it will attempt to configure and start the components it has installed. This will lead to a successful completion of your infrastructure tier installation.

Middle Tier Installation

The middle tier installation will be carried out by the OS user ocsmi



At first screen again we select the advanced installtion option.



Now specify the ORACLE_HOME for your OCS Middle Tier.



Choose that you want to install OCS Application here on this screen.



As usaul the OUI will validate your system before carring out the installation.



Choose the OCS applications you would like to install,i choose evrything other than oracle mail and discussions.



In this screen give the hostname and port of your OID server which you installed as a part of your infrastructure installation.



Give the password for the orcladmin user of your OID.



Here you can specify the components you want to associate with the available OCS databases.



The seelcted OCS Applications require a SMTP server, here you must specify that server and port.



Choose a automatic port selection or a static port selection here.



Specify the instance name for your middle tier and the password for the super user in this screen.



Specify a host name for the calender services here



The OUI now displays a summary of the installation it is going to carry out.



The OUI now start the installation process



You must have root privilages on the system to execute the root.sh as a part of the isntallation.



The installer now starts configuring and starting the products you installed,this really is time consuming and you should take a break here.

If all goes well, you installation would be complete and the access information can be found in the supportinfo.txt file in your ORACLE_HOME/install directory.
