File Information Menu Options

This chapter tells you what to keep in mind while reviewing the File Information menu options:

• Check the integrity of key facilities z/OS uses for processing data sets on the system, such as the PASSWORD facility, load library directories, and the volume tables of contents (VTOCs)
• Find key files and user data sets
• Find wasted space on the system
• Compare versions of the same data file to detect possible unauthorized changes

This chapter describes why you should track the history of key applications data sets through SMF records. It also describes how freezing a file can aid you in monitoring changes over an extended period of time.
