Memory requirements for using the installver_wbi command are
related to the size of the installed file set for the product. For
the basic verification scenario, comparing an installed file set with
the provided bill of materials might require a maximum heap size of
128 MB to 256 MB.
About this task
If you need more memory for either
a product verification or a baseline checksum verification, you must
increase the maximum heap size setting for your Java™ Virtual Machine (JVM) by including a setting
in the installver command
script. (The installver_wbi command
calls the installver command
script.)
Note: On i5/OS® systems, the default Java maximum heap size is *NOMAX, so there is
no need to increase it.
To handle out-of-memory situations,
perform the following steps.
Procedure
- Edit the installver command
script:

On Linux® and UNIX® platforms: Edit the install_root/bin/installver.sh file.
On Windows® platforms: Edit
the install_root\bin\installver.bat file.
- Add or increase the maximum heap size setting:

On Linux and UNIX platforms: Change the
following line: "$JAVA_HOME"/bin/java \
to: "$JAVA_HOME"/bin/java -Xmx256M \
On Windows platforms: Change
the following line: "%JAVA_HOME%\bin\java" "-Dproduct.home=%WAS_HOME%"
to: "%JAVA_HOME%\bin\java" -Xmx256M "-Dproduct.home=%WAS_HOME%"
- Save your changes.
Results
After you change the setting, run the
installver_wbi command to
verify that it works correctly.
