How to install Wepshere application server 8 or 8.5 by IBM Installation MANAGER

From version 8 onwards Websphere is using IBM Installation Manager as a single software to do all
installation and upgrades.No need of update installer to  install fixpacks as IBM installation manager will take care of this.

There is a good post in IBM developer works by Scott Johnston
Installing websphere using IBM Installation Manager

Silently Install IBM Installation manager:

  ./installc -acceptLicense

Record a response file to silently install WebSphere Application Server:

  Go to /Installation Manager/eclipse where the IBMIM is present 

 

   ./IBMIM -record /tmp/install_was.xml -skipInstall /tmp/imregistry
   install_was.xml is the name of response file
  skipInstall is used to perform a mock install it wont do the installation

Once IM opens select File->Preferences and click Add Repository.
The repository can be located in local machine ,network drive or IBM passport Advantage

Click Ok.
Explore the IM preferences for the way you want.
Click Ok to  save and close preference window.

Click Install  and then
Select appropriate version,accept license,accept product installation directory and select all features needed.After reviewing the summary click install to record the response file.

Exit on successful recording of response file

Next use the response file to silently install the websphere
Go to InstallationManager/eclipse/tools
./imcl -acceptLicense -input /tmp/install_was.xml -log /tmp/install_was.log

If Installation is success the log file will be empty.
