Installing Installation Manager on z/OS
To install and maintain software products, you can create one or more Installation Managers on your z/OS® system.
Before you begin
IBM® Installation Manager Version 1.8.5 or later is required to install the product.
Procedure
What to do next
cd /InstallationManager/bin/eclipse/tools
imcl -version
You are now ready to install products by using IBM Installation Manager.
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.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 IBM HTTP Server for 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.
