Guidelines for Parameter Files and Scripts

Guidelines for Parameter Files and Scripts

When you create parameter files and scripts, use the following guidelines:
  • To easily maintain flexibility and control of session file locations, use a script to replace placeholders in a parameter file.
  • Consider the estimated file size and file system capacity when you define file locations.
  • Avoid organizing files according to business logic if the sessions and workflows need to access business-related files at the same time. For example, if you store California files on one file system and New York files on another, a bottleneck might occur if the session needs to access both files at the same time.
  • When possible, place files for different partitions of the same source, target, or lookup on different file systems.
