The SPOOLKIT package contains the SFLIST module and some associated files, intended to make life easier for system administrators when working with spool files. file The module provides the following functions:

  • Total SPOOL utilization by user
    The initial 'Spool File Overview' screen shows total spool utilization (number of files, number of 4k-blocks used) per user. This is where you'd start looking for users that occupy too much space.
  • Spool file manipulation
    After selecting a particular user on the overview screen that user's spool files are listed on the UFLIST screen (with the newsest files on top). They can be viewed, received, renamed, purged or transferred to another user.
  • The integrated SBROWSE request allows viewing even open spool files (e.g. current console logs).
  • Spool volume utilization
    Two reports are provided:
    • SPOOLVOL summary report for summary SPOOL utilization by volume, and
    • 'SPOOLVOL volser' report with utilization details for a selected volume, listing all files that have data blocks on the volume, and the number of blocks occupied on the volume by each file.
    While this may be of academical interest only most of the time, you will need the information if you drain a spool volume and want to know which spool files occupy the last few blocks that prevent you from taking the volume offline.
Pre-Requisites
Full use of all SFLIST functions requires CP privilege classes D and E, and also access to full-pack overlay minidisks for all SPOOL volumes.
While the basic SFLIST spool file displays can be used with just class D, the SBROWSE function and part of the SPOOLVOL data require access to some CP control blocks, and to control and data blocks on disk.

Documentation
File SFLIST README of the package gives more details about these pre-requisites and it also provides a short introduction.
More detailed documentation is available from CMS help files.
