CRC-based r-code
If you supply new or modified CRC-based r-code files, you must precompile the procedures against a version of the database that is structurally the same as the user's database. You must also compile it on a machine of the same class, same user interface, and same combinations of DataServers (if any). However, since the r-code you create has no time-stamps, it does not matter when the database tables were created or modified.
