Checksum (installver) command

After installing the product or after installing maintenance packages, you can use the installation verification utility (IVU) to compute checksums of the installed file set to verify the checksum against the checksum in the product bill of materials.

The IVU tool is installed during the installation of the following product components:

• WebSphere Application Server Network Deployment


• Application Client


• IBM HTTP Server


• Web server plug-ins


• Update Installer for WebSphere Application Server

After installation, verify actual checksums of installed files against a bill of materials that ships with the product. If the checksums match, the installed product is installed correctly. If the checksums differ, review the differences to determine whether a problem exists.
