Installing Installation Manager on z/OS
You can create one or more Installation Managers on your z/OS® system to install and maintain software products.
Before you begin
Procedure
What to do next
You can verify that Installation Manager is correctly installed by editing and submitting the
GIN2CMD sample job. Alternatively, you can log in to the UNIX
System Services shell under the user ID that created Installation Manager, and run the Installation
Manager imcl command from the eclipse/tools subdirectory of
the Installation Manager binaries location. For
example:
cd /InstallationManager/bin/eclipse/tools
imcl -version
You are now ready to install products by using IBM Installation Manager.
Authorizing additional users to a group-mode Installation Manager: To allow additional
users to access a group-mode Installation Manager, make sure that they meet the requirements listed
in the first step of the procedure, and then connect them to the owning group for the Installation
Manager by using the TSO CONNECT
command:
CONNECT user2 GROUP(IMGROUP)
To install
another Installation Manager, follow the steps in the procedure, selecting a new user ID and group
(if appropriate) and new binaries and runtime data locations. Do not share binaries or runtime data
locations between separate Installation Manager installations.Correcting file ownership or permission problems: If you accidentally invoke Installation
Manager from the wrong user ID, some files might end up with ownerships that prevent normal use of
that Installation Manager instance. To correct this problem, log on to a super user or other
privileged user ID and reset the file ownership and permissions for the Installation Manager
binaries and runtime data. For example:
chown IMADMIN:IMGROUP /InstallationManager/bin
chmod 775 /InstallationManager/bin
chown IMADMIN:IMGROUP /InstallationManager/appdata
chmod 775 /InstallationManager/appdata
If
the users of a group-mode Installation Manager do not have umask set to allow
group-write permission on created files, you might also have to perform this step when you switch
from one user ID to another. You might also need to set permissions and owners for the product files
that you install with the Installation Manager to ensure that maintenance can be performed from
other user IDs in the group.Upgrading the Installation Manager: To upgrade an Installation Manager to a new level of the Installation Manager product, update your Installation Manager installation kit and sample jobs by following the instructions in Obtaining an Installation Manager installation kit for installing Liberty on z/OS. Then re-run your GIN2INST job, specifying the same parameters that you used when you created the Installation Manager. Running the job updates the Installation Manager binaries to the level of the Installation Manager installation kit.
