Comparing specific file and component checksums
Specify individual files or components to include in the bill of materials verification.
Before you begin
Install the product before comparing checksums of individual files and components.
About this task
This topic describes how to use inclusion properties to specify individual files and components.
By default, IBM includes all files in the checksum comparison except for the 78 IBM excluded files
I CWNVU0160I: [ivu] Verifying. I CWNVU0170I: [ivu] The installation root directory is C:\IBM\WebSphere\AppServerV602\ I CWNVU0300I: [ivu] The total number of user excluded files found are 0.

I CWNVU0470I: [ivu] Starting to analyze: activity I CWNVU0480I: [ivu] Done analyzing: activity ...Several different methods are provided to include only certain files in the comparison.
Procedure
- Compare checksums and include specified components only in the comparison:
For example, you might include the activity component:
The resulting messages show the inclusion

For example, you might include only the properties/version/proxy.server.component file, which was changed to generate the checksum difference in this example
installver.bat -log -include properties/version/proxy.server.componentThe result shows that the included file was in the comparison, which scanned 285 components looking for all components that refer to the file

I CWNVU0400I: [ivu] Total issues found : 1 I CWNVU0340I: [ivu] Done.If you know that a file is in only one component, we can speed up the comparison by restricting the comparison of the file to the relevant component
installver.bat -log -includecomponent proxy.server -include properties/version/ proxy.server.componentThe result shows the comparison was restricted to one component

Results
When you issue one of the checksum commands from the app_server_root/bin directory, the status of the command is displayed on the terminal console or in a log file.
