Handling out-of-memory situations

Memory requirements for using the installver 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.

Install the product at the V6.0.2 level or later to install the installver command tool. After installing the command, you can increase the maximum heap size setting.

Overview

If you need more memory for either a product verification or a baseline checksum verification, increase the maximum heap size setting for your JVM by including a setting in the installver command script.

Procedure

Edit the installver command script:
- Edit the app_server_root/bin/installver file.
Add or increase the maximum heap size setting:
- Change the following line:
```
"$JAVA_HOME"/bin/java \
```
  to:
```
"$JAVA_HOME"/bin/java -Xmx256M \
```

Results

After you change the setting, run the installver command to verify that it works correctly.
