Problem(Abstract) |
During an installation of IBM® WebSphere® Application
Server V5.0 on AIX® 5.3, the prerequisite checker runs and the following
message appears:
"Operating System Level Check: A supported operating system was not
detected. Installation may not be successful." |
|
|
|
Cause |
The message appears because the WebSphere prerequisite
checker does not recognize AIX 5.3 or later. It declares that AIX 5.3 is
not supported, as AIX 5.3 was not available when the WebSphere Application
Server V5.0 product was originally released. |
|
|
Resolving the
problem |
The following solutions are possible to bypass the
warning.
Recommended solution
Bypass the warning by clicking Next.
This message is a warning only. Check the WebSphere
Application Server system requirements page for the latest status of
supported operating systems. If the Web page or IBM service declares
support for your operating system, click Next to continue the
installation.
The following is a sample screenshot of the warning in the product
installation wizard when the product is installed on AIX 5.3:
Alternate Solution
Alternatively, this problem can be avoided by using this solution
instead of the preceding solutions proposed. In this case, the alternate
solution is to bypass prerequisite checking completely by invoking the
installer differently.
To suppress the warning page entirely, launch the installer using the
following command.
install -W
osLevelCheckActionBean.active=false -W
osLevelCheckPanelBean.active=false |
 |
Another Alternate Solution
Alternatively, this problem can be avoided by using this solution instead
of the preceding solutions proposed. Modify the prereqChecker.xml
file to recognize AIX 5.3 as a supported operating system for WebSphere
Application Server V5.0.
To do so, edit the file,
install_root/waspc/prereqChecker.xml, before
starting the installation.
Note: You must edit the file separately for the base, Network
Deployment, and Enterprise editions of the product.
- Locate the following directory on the installation media:
install_root/waspc |
Note: install_rootrefers to the source installation
directory for the product.
|
- Copy the following files from the directory located in step 1 to a
temporary directory:
prereqChecker.xml
prereqChecker.dtd |
Both prereqChecker.xml and prereqChecker.dtd must be
present in the same directory to allow the installer to process the
prerequisite checker data.
|
- Edit the temporary copy of the prereqChecker.xml file. Locate
the section labeled with the osLevel tag for AIX 5.1.0.2
(An example is provided in step 4).
Alternatively, you can use the prereqChecker.xml file attached to
this technote and skip to step 6.
- Add an entry for AIX 5.3 after the end-osLevel tag for
AIX 5.1.0.2, as shown in the following example. The bold
text indicates the entry that should be inserted into the
prereqChecker.xml file.
<osPlatform
type="aix">
.
.
.
<osLevel version="5.1.0.2" checkId="aix5002" category="osversion"
displayName="AIX 5.1.0.2">
.
.
.
</osLevel>
<osLevel version="5.3.0.0" checkId="aix5300"
category="osversion" displayName="AIX 5.3.0.0">
</osLevel>
</osPlatform> |
Note: The preceding text might appear differently in a text editor
due to formatting variations.
 |
- Save the edited prereqChecker.xml file.
- Invoke the installation wizard from a command prompt, using the
parameter provided in the following example:
./install -W
osLevelCheckActionBean.configFilePath="/tmp/prereqChecker.xml" |
Note: The reference to /tmp in this example should be
replaced with the full path to the appropriate directory containing
prereqChecker.xml.
 |
- The installation should proceed as normal. The installation wizard
should recognize AIX 5.3 as a supported operating system. Normal
installation procedures can be followed afterward.
