Install in group mode

We can use IBM Installation Manager group mode to allow multiple users to use a single instance of Installation Manager to manage software packages.

• Group mode allows multiple users to use a single instance of IBM Installation Manager to manage software packages.

  This does not mean that two people can use the single instance of IBM Installation Manager at the same time.

• Group mode is not available on Windows or IBM i operating systems.

• If you do not install Installation Manager using group mode, you will not be able to use group mode to manage any of the products that you install later using this Installation Manager.

• Make sure that you change the installation location from the default location in the current user's home directory to a location that is accessible by all users in the group.

• Set up your groups, permissions, and environment variables as described in the Group mode road maps in the IBM Installation Manager v1.4 Information Center before installing in group mode.

• For more information on using group mode, read the Group mode road maps in the IBM Installation Manager v1.4 Information Center.

Procedure

1. Create a group.

   For example:

   wasadmin
   

2. Create multiple user IDs.

   For example:

   installadmin
   

   imuser
   

3. Make the group that you created the primary group for the user IDs that you created.

4. Make sure that the umask for all IDs is 002.

   See the IBM Installation Manager v1.4 Information Center for alternatives if for some reason you cannot set the umask.

5. Create a file system where all the of the products will be installed.

   For example:

   /WASProducts
   

6. Give access to this file system to all of the user IDs that you created.

7. Use one of the user IDs that you created, install Installation Manager in group mode to the file system that you created.

   Use installadmin, for example, to install Installation Manager in group mode using the GUI:

   groupinst -dataLocation /WASProducts/IMAppData
   

8. Use one of the user IDs that you created, start Installation Manager and install a WAS product to the file system that you created.

   Use installadmin, for example, to install the trial edition of the Network Deployment product in:

   /WASProducts/WASV8/NDTRIAL
   

   with the Samples option.
9. Exit Installation Manager.

10. Use one of the other user IDs that you created, you can maintain the product installation.

    Use imuser, for example, to update the trial edition of the Network Deployment product with additional optional features, remove options, or add fixpacks.

    1. As root user ID,

       • For WAS only, change to the WAS_HOME/instutils directory and run the following command:

         chutils -setowner=imuser
         

         If you do not change to WAS_HOME/instutils, specify -installlocation=installation_directory.

       • For all other products...

         chown -R imuser WAS_HOME
         

    2. Start Installation Manager under the imuser user ID, and perform any necessary changes to the installation.
