Deployment
When you've finished testing, you can deploy the final application to the production server. This may require coordinating and scheduling time with several departments.
Whenever you deploy to a new machine on a separate or different environment, be careful of the operating system differences that can skew results. Here are some potential problems:
If the testing UNIX, and the production UNIX systems have different locale settings, the application may not perform at all, or it may produce different results. Because of environment differences, the same system library search path settings on one UNIX machine will produce correct results but on another machine will produce the wrong results.
Different Windows systems can have different directory permissions.
Different mainframe environments may require technical resources or administrative scheduling to install the server in the correct data set or library.
VMS test area installations could require the individual install option; whoever installs this must understand DCL.
