Problem |
Some WebSphere® Application Server problems
are resolved by applying operating system patches, also know as filesets
or fixes. Following are directions for applying AIX® patches |
|
Cause |
AIX fixes are published as installp images on an external
Web site.
Fixes are packaged differently for each AIX Maintenance Level, so
correctly identifying the current Maintenance Level is necessary to insure
that the fix resolves the WebSphere Application Server problem.

Solution |
For example, installation of IY19277 resolves a problem
where IBM® HTTP Server does not start after upgrading the WebSphere
Application Server plug-in, and when upgrading to AIX 4.3.3.0, Maintenance
Level 6 or higher. In this case, the indication is that the httpd process
fails to start with a SIGSEGV.
The main link for finding AIX fixes is located at:
http://www.ibm.com/servers/eserver/support/pseries/aixfixes.html
Resolving the problem requires downloading and applying an AIX fix:
- Click the above link.
- Choose the OS level in the Specific Fixes line.
- Choose APAR Number or Abstract in the Search by box from
the dropdown list.
- Type IY19277, or the appropriate fix number, into the Search
string field.
- Click Go.
- Highlight the fix number; for example: IY19277.
- Click Add to my download list,
- Click Continue.
- Select your current maintenance level; for example: 4.3.3.0.06 is
Maintenance Level 6.
- You can determine your AIX Maintenance Level with the
following command:
instfix -i | grep AIX_ML
- Usually, the last line of output identifies your current
level. Not all filesets are required for WebSphere Application Server to
run correctly. Here is an example:
All filesets for 4.3.1.0_AIX_ML were found
All filesets for 4330-06_AIX_ML were found
Not all filesets for 4330-07_AIX_ML were found
Not all filesets for 4330-08_AIX_ML were found
- If the value returned is Not all filesets for
4330-09_AIX_ML were found, run the following command:
instfix -icqk 4330-09_AIX_ML | grep ":-:"
The components on the list returned are components that must be
installed to change the message from "Not all filesets..." to "All
filesets...".
- Click Continue.
- Download the required filesets.
- Download into an empty directory.
Use ls -a to make sure .toc is not present.
- Each item for download is a separate installation image for a specific
component of AIX or an AIX product. SMIT installs only updates (these
installp files) for products that are actually installed.
- Use SMIT to install; you do not need to commit.
