Overlay hash files
An overlay hash file, also called a snapshot, is an XML file that contains keys for all the objects in a particular version of BMC Remedy AR System or a BMC Remedy AR System application:
- For fields and views, the key is the object's ID.
- For all other objects, the key is the object's name.
The Best Practice Conversion Utility (BPCU) compares objects in an overlay hash file with those in a customized BMC Remedy AR System component or application. BPCU produces a difference report that contains the results of the comparison.
- Download the latest version of the OverlayHashFile.zip file from the BMC Communities website.
Updates to the overlay hash file between patch releases are posted to BMC Communities website: https://communities.bmc.com/docs/DOC-32560.
Always make sure to download the latest version from this location, and use the same version of the hash file as that of the BPCU.
- Uncompress the .zip file and extract the OverlayHashFile.xml file to your development server.
If you are upgrading from the following releases, you can use the overlay hash file (OverlayHashFile.xml) to compare the objects in your customized applications with the objects in the origin applications:
