Verifying checksums of installed files

After installing the product or after installing maintenance, compute checksums of installed files to verify against the product bill of materials.

Before you begin

Install the product at the V6.0.2 level or later to install the installver command tool. After installing the command, you can compare checksums of the installed files to the shipped bill of materials.

Why and when to perform 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.

The installver tool can also compute a new baseline checksum for each file in the inventory of a configured system to use to identify file changes in 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, other tasks are also possible.

Steps for this task

Result

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.

If you detect a problem, 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.

If you have not yet created a cell profile, a deployment manager profile, or a stand-alone application server profile, go to Creating profiles through the graphical user interface to see how to create a profile.
