You must ensure your HP-UX system is prepared to install IBM WebSphere ESB.
Before you begin
The installation uses an InstallShield for Multiplatforms (ISMP)
wizard. You can also install the product silently. Silent mode is invoked
at a command line with a parameter that identifies an options response file,
which you edit before installing.
Why and when to perform this task
Use the following procedure to prepare the operating system for
installation of WebSphere ESB.
Steps for this task
- Log on as root.
You cannot install the product correctly
as a non-root user. If you create copies of the product CDs, do so as root.
Copies made by non-root users do not preserve the correct file attributes
and do not work.
- Verify that the umask setting is 022.
To verify
the umask setting, issue the following command:
umask
To set the umask setting to 022, issue the following command:
umask 022
- Optional: Install the Mozilla browser if it is not
already installed. The Mozilla browser supports the Launchpad console.
Download and install the Mozilla browser from http://www.mozilla.org.
- Optional: Export the location of the supported browser.
Export the location of the supported browser using a command that
identifies the actual location of the browser.
For example, if the
Mozilla package is in the
bin/mozilla directory, use the following
command:
EXPORT BROWSER=/usr/bin/mozilla
- Stop all Java processes on the machine on which you are installing
the product that are related to WebSphere Application Server, including WebSphere ESB and WebSphere Process Server.
- Stop any Web server process such as the IBM HTTP Server.
- Provide adequate disk space.
For the space required
to install WebSphere ESB and
related products, see Required disk space for HP-UX platform.
- Set kernel values to support WebSphere ESB.
Several HP-UX kernel values are typically too small for the product.
See Setting kernel values on HP-UX systems for
instructions on how to set kernel values.
- Verify that prerequisites and corequisites are at the required
release levels.
Although the Installation Wizard checks for
prerequisite operating system patches, review the prerequisites in the List
of supported hardware and software for WebSphere ESB if
you have not already done so. To access this information, see WebSphere ESB detailed
system requirements at http://www.ibm.com/software/integration/wsesb/sysreqs/.
Refer
to the documentation for non-IBM prerequisite and corequisite products to
learn how to migrate to their supported versions.
- Verify that the system cp command is used, rather than the cp command
provided by emacs or other freeware.
If you install the product
using a cp command that is part of a freeware package, rather than
with the system cp command, the installation might appear to complete
successfully, but the Java 2 SDK that the product installs might have missing
files in the install_root/java directory (where install_root represents
the installation directory of WebSphere ESB).
Missing
files can destroy required symbolic links. You must remove the freeware cp command
from the PATH in order to install the WebSphere ESB product
successfully.
If you have emacs or other freeware installed on your
operating system, perform the following steps to identify which cp command
is being used by the system, and to deactivate the freeware cp command
if it is being used:
- Type which cp at the command prompt before running
the installation program for the WebSphere ESB product.
- If the resulting directory output includes freeware,
remove the freeware directory from your PATH. For example,
if the output is similar to .../freeware/bin/cp, remove the
directory from the PATH.
- After you install WebSphere ESB,
add the freeware directory back to the PATH.
- Verify that the Java 2 SDK on your copies of the product CDs is
functioning correctly.
If you created your own product CDs from
ISO images or by copying the actual CDs, perform the following steps to verify
that the Java 2 SDK is working correctly.
- On your created product CD for WebSphere ESB CD
1, navigate to the /mnt/JDK/repository/prereq.jdk/java/bin directory. To do this, issue the following command:
cd /mnt/JDK/repository/prereq.jdk/java/bin
- Verify the Java 2 SDK version. To do this, issue
the following command:
./java -version
The command completes successfully with no
errors when the Java 2 SDK is intact.
- Repeat this procedure on your created product CD for WebSphere ESB CD
2.
Result
This procedure prepares the operating system for installation
of WebSphere ESB.
What to do next
After preparing the operating system, you can install WebSphere ESB.
See Installing WebSphere ESB for
descriptions of the various installation alternatives available.
