Steps as follows

1) Download the necessary packages and the fixpacks from the Passport Advantage
2) Ensure the necessary access is available .. in our case its root ( Though we can install using a non-root user)
3) Create the necessary filesystems ( we will be installing in /apps )
4) Check for sufficient space in the filesystem to extract the zip files and the installation

Below are the files which we have downloaded and transferred in the server

Installation Manager 1.6
agent.installer.linux.gtk.x86_1.6.0.20120831_1216.zip

WAS ND Fixpack 8.5.5.3
8.5.5-WS-WAS-FP0000003-part1.zip
8.5.5-WS-WAS-FP0000003-part2.zip

WASND 8.5.5 SDK
WS_SDK_JAVA_TEV7.0_1OF3_WAS_8.5.5.zip
WS_SDK_JAVA_TEV7.0_2OF3_WAS_8.5.5.zip
WS_SDK_JAVA_TEV7.0_3OF3_WAS_8.5.5.zip

WASND 8.5.5
WASND_v8.5.5_1of3.zip
WASND_v8.5.5_2of3.zip
WASND_v8.5.5_3of3.zip

I have created few folders within /IbmSoftware/was8.5.5/ and saved the corresponding files in these folders

PATH
/IbmSoftware/was8.5.5/IM1.6
agent.installer.linux.gtk.x86_1.6.0.20120831_1216.zip
/IbmSoftware/was8.5.5/was8.5.5
WASND_v8.5.5_1of3.zip
WASND_v8.5.5_2of3.zip
WASND_v8.5.5_3of3.zip
/IbmSoftware/was8.5.5/sdk
WS_SDK_JAVA_TEV7.0_1OF3_WAS_8.5.5.zip
WS_SDK_JAVA_TEV7.0_2OF3_WAS_8.5.5.zip
WS_SDK_JAVA_TEV7.0_3OF3_WAS_8.5.5.zip
/IbmSoftware/was8.5.5/fixpack
8.5.5-WS-WAS-FP0000003-part1.zip
8.5.5-WS-WAS-FP0000003-part2.zip

For eg as below image

5)Installation of Installation Manager

a) Unzip the Installation Manager setup agent.installer.linux.gtk.x86_1.6.0.20120831_1216.zip

#unzip agent.installer.linux.gtk.x86_1.6.0.20120831_1216.zip

The extracted folder

Edit install.xml to define the location for IM installation
b) #vi install.xml

Add the below entries in the install.xml file

<profile kind=’self’ installLocation=’/apps/InstallationManager/eclipse’ id=’IBM Installation Manager’>
</profile>

Highlighted the entries in yellow where “/apps/InstallationManager/eclipse” is the location where I need to install the Installation Manager

c) Install IM1.6 silently
Execute #./installc –acceptLicense

This command reads the install.xml file and installed it in the location mentioned in it

Once the installation is completed the message “Installed <package> to the <location> directory is displayed

d) Verify the installation and the versions of Installation Manager

Navigate to /apps/InstallationManager/ folder

Execute ./imcl -version to check the version of IM fron /apps/InstallationManager/eclipese/tools/

THIS IS HOW WE INSTALL INSTALLATION MANAGER SILENTLY

6) CREATING THE Response xml files

a) Launching Xming to display the graphical interface of the commands
Note : you can use any other X11 utility for unix but I prefer Xming

============================================================================

CONFIGURING XMING

============================================================================

1)   Download Xming and install it on ur local machine from where you want to connect
2)   Execute the XLaunch icon
3)   Select Multiple Windows and “Next”

Select “Start no Client”

Select “No Access Control”

Click on Finish

Lauch Putty
And expand the Putty Settings > Connections >> SSH >> X11
Enable “X11 Forwarding” and mention localhost:0
Now put the ip and login

Once logged in enter “w” to determine the ip you are connecting to the WAS server with .. Here its 10.0.0.2

Export the display variable using
#export=DISPLAY=10.0.0.2:0.0

Run xclock to check if it works

This confirms that ths X11 forwarding works

7) Generating the response.xml files

a) Generating the response.xml files using the record funciton of IM

Execute #./IBMIM –record /apps/WAS8.8.8_Install.xml –skipInstall /tmp/was8.5.5

Where

-record : ensures we are using the record function
/apps/WAS8.8.8_Install.xml : is the response file which will be created ( any file name can be used)
-skipInstall : This is to skip the installation and only create the response
/tmp/was8.5.5 : is a temp location where the Installation Manager will extract the files ( this can be any location )

This will launch the Installation Manager in Skip Install Recording mode (Highlighted in Yellow)

b) Add the repositories needed for WAS 8.5.5 install
c) We will be installing the fixpack also together along with the base install

Select the repository.config for was8.5.5

Similarly do it for the repository.config for SDK folder and the fixpack 3

Click OK

c) Then Click Install to launch the installer function

This will display the packages for the installation ( We wil deselect the SDK for Liberty profile as its not needed for now)

e) Accept the License

f) Provide the path of the Shared Repository Directory ..

I gave it /apps/IMShared as I want all the installation binaries in /apps

g) Provide the path where you want the WAS8.5.5.3 to be installed

h) Select the options needed

Summary screen is displayed. Click Install
Here you can observe that the IBM WAS version is provided 8.5.5.3
IM has automatically detected the Fixpack also added in the repository

Click Finsh .

i) A file /apps/WAS8.8.8_Install.xml which is the response file for WAS8.5.5.3 Installation

Response file

Open the file /apps/WAS8.8.8_Install.xml
Some observation :
We can see the repository location for the packages
“/ibmSoftware…….”

j) Modify the installLocation as per your needs
Change the Profile id as required .. though not necessary unless you allready have an installation of was with the same profile id
Eg “ IBM WebSphere Application Server V8.5 MY SERVER”

Verify that the files once again for any typo error and save it
