Verifying checksums of installed files

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.

Before you begin

Installing the product also installs the IVU, which is the installver command-line tool.

The installation verification utility is new as of the Version 6.0.2 level, which means that you must install Refresh Pack 2 for Version 6.0 of WebSphere Application Server for some operating system platforms, to install the IVU. Only a few operating system platforms were new as of Version 6.0.2 and thus, have their own installation disc at the Version 6.0.2 level. Refresh Pack 2 is required for all of the other platforms. See Installing V6.0.2 WebSphere Application Server for more information.

About this task

This topic describes using the installver command to compute a checksum on the installed files and compare the checksum to the product bill of materials.

You can also use the IVU to compute a new checksum for a system after you make significant configuration changes. The installver tool computes a new baseline checksum for each file in the inventory of a configured system to use to identify file changes in the later comparisons. Such a comparison is useful for detecting file tampering on the configured system, for example.

Although the most common use of the tool is to compare the product bill of materials to the installed file set after installation or after installing maintenance, other tasks are also possible.

Procedure

Results

When you are satisfied that your installed or updated file set matches the product bill of materials, you are finished installing and verifying the product or updating and verifying the product.

IBM Support has documents and tools that can save you time gathering information needed to resolve problems. If you detect a problem, before opening a problem report see if the problem is a known problem by checking the Support page:

What to do next

After verifying your installation, you can create profiles or deploy an application on an existing application server profile.

After installing, updating, and verifying, the next step is to use the product. Start the application server to use the administrative console to deploy an existing application. See Fast paths for WebSphere Application Server for more information.
