You can create one or more Installation Managers on your z/OS® system to install and maintain
software products.
Before you begin
In order to install WebSphere Application Server Version
8.5, your Installation Manager must be at Version 1.5.2 or above.
Install
the fix for z/OS APAR OA34228 on each z/OS system that will run IBM
Installation Manager to allow the copying of files with extended attributes.
Decide
in which of the following modes you want to run the Installation Manager:
- admin mode
- In admin mode, the Installation Manager is installed from a superuser
ID (uid=0) and can be invoked from any superuser ID. There can only
be one admin-mode Installation Manager on a system.
- user mode
- In user mode (also called nonAdmin mode), the Installation Manager
can be invoked only by the user that installed it. There can only
be one user-mode Installation Manager for a user.
- group mode
- In group mode, the Installation Manager can be invoked by any
user ID that is connected to the owning group for the Installation
Manager (the default group of the user ID that creates it). There
is no limit to the number of group-mode Installation Managers that
you can have on a system.
The Installation Manager will consist of two
sets of files—a set of executable files that are copied or updated
from the installation kit, and a set of runtime data files that describe
the products installed by this Installation Manager. Both sets of
files must be writeable by the Installation Manager. You must select
locations for both the executable and runtime data for each Installation
Manager.
Table 1. Default
locations for Installation Manager files. The following
table shows the default locations for the Installation Manager executable
files (binaries) and runtime data on z/OS.Files |
Admin or group mode |
User mode |
Binaries |
/InstallationManager/bin |
$HOME/InstallationManager/bin |
Runtime data (also called agent data) |
/InstallationManager/appdata |
$HOME/InstallationManager/appdata |
These locations are assumed in the Installation Manager
documentation and sample jobs. If these names are not appropriate
for your system or if you choose to have several Installation Managers,
you can choose different names and specify them when you create the
Installation Manager.
- Make sure that the fix for z/OS APAR OA34228 is installed
on your z/OS system.
- Create a user ID and group to own the Installation Manager.
This user ID must have the following attributes:
- Read/write home directory
- Read access to FACILITY profile BPX.FILEATTR.APF
- Read access to FACILITY profile BPX.FILEATTR.PROGCTL
- Read access to FACILITY profile BPX.FILEATTR.SHARELIB
- Read access to UNIXPRIV profile SUPERUSER.FILESYS.CHOWN or CHOWN.UNRESTRICTED
- Read access to UNIXPRIV profile SUPERUSER.FILESYS.CHANGEPERMS
The user ID that creates the Installation Manager will
become the initial (possibly only) user ID that can invoke that particular
Installation Manager. If you create an Installation Manager in group
mode, the default group for this user will become the owning group
for the Installation Manager. This user ID must have a read/write
home directory.
You can use an existing user ID if it meets
these requirements.
If you installed the
Installation Manager installation kit with SMP/E, you can use the
Installation Manager sample job GIN2ADMN in SGINJCL to create this
user ID and group as well as to assign appropriate permissions.
When
you invoke a group mode Installation Manager, your effective group
must be the same as the group that created the Installation Manager.
It is no longer necessary to set your umask to allow group-write
when invoking a group-mode Installation Manager. Instead, an Installation
Manager running in group mode will turn on group-write by default
then reset the umask to its previous value when Installation Manager
processing is complete.
- If the Installation Manager binaries and runtime data will
not reside in existing read/write file systems, create file systems
for the data and mount the file systems read/write.
The
file systems should be owned by the user ID and group that will create
the Installation Manager and have permissions 755 for an admin or
user-mode Installation Manager or 775 for a group-mode Installation
Manager.
If you installed the Installation
Manager installation kit with SMP/E, you can use the Installation
Manager sample job GIN2CFS in SGINJCL to allocate and mount a file
system to hold the binaries and runtime data.
The Installation
Manager creation process described below will create the binaries
and runtime data directories if they do not already exist.
- Log in to the Unix system services shell under the owning
user ID for the Installation Manager, and change the directory to
the location of the Installation Manager installation kit.
cd /usr/lpp/InstallationManager/V1R5
The
installation kit must be at Version 1.5.2 or above.
- Run the installc, userinstc,
or groupinstc command from the installation kit
to create the Installation Manager.
- To create an Installation Manager in admin mode, issue the following
command from the shell:
installc -acceptLicense
-installationDirectory binaries_location
-dataLocation appdata_location
- To create an Installation Manager in user mode, issue the following
command from the shell:
userinstc -acceptLicense
-installationDirectory binaries_location
-dataLocation appdata_location
- To create an Installation Manager in group mode, issue the following
command from the shell:
groupinstc -acceptLicense
-installationDirectory binaries_location
-dataLocation appdata_location
You can omit the -installationDirectory and -dataLocation
parameters if you use the default locations.
If
you used SMP/E to install the Installation Manager installation kit,
you can use sample job GIN2INST in SGINJCL to create an Installation
Manager.
- You can now unmount the Installation Manager installation
kit.
What to do next
You can verify that the Installation Manager is correctly
installed by logging in to the Unix System Services shell under the
user ID that created the Installation Manager and running the Installation
Manager imcl command from the
eclipse/tools subdirectory
of the Installation Manager's binaries location. For example:
cd /InstallationManager/bin/eclipse/tools
imcl -version
You are now ready to install products
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 described above and then connect them to the owning group
for the Installation Manager using the TSO CONNECT command:
CONNECT user2 GROUP(IMGROUP)
To create an additional Installation Manager, follow the
steps in the procedure described above, 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 Managers.
Correcting file ownership or permission
problems: If you accidentally invoke an Installation Manager
from the wrong user ID, some files might end up with ownerships that
prevent normal use of the Installation Manager. 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 switching 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, download or install
the new level of the IBM Installation
Manager installation kit and mount it on your system. Then, change
directory to the new level of the installation kit and reissue the
same installc, userinstc, or groupinstc command
that you used to create the Installation Manager. This will update
the Installation Manager's binaries from the new installation kit.
