PSTAT is a utility which helps regular users and system managers
analyze and control processes on OpenVMS systems.  This is 
the release of PSTAT v2.1; this version adds a lot of functionality to
the utility.  The major changes from the previous version are: cluster-wide
operation support; deletion of selected processes from the command prompt
with confirmation and log messages; /BEFORE and /AFTER qualifiers; handling
of suspended processes on the host node; ability to select processes by the
ratio; also a new feature which speeds up the operations in the continuous
update mode (/LOCK).
  Here are some examples of using PSTAT:
        o  Selection of processes by various characteristics - 
           for example,
           $ PSTAT /USER=SM*TH /IMAGE=MA*L /BEFORE=TODAY /FULL
           will display detailed information about processes created
           before TODAY of users matching the specified username who
           run the image set by the /IMAGE qualifier, and
	   $ PSTAT /TYPE=(DIALUP, REMOTE) /IMAGE=SPSS
	   will display information about dialup and remote processes 
           whose current image is matched by the /IMAGE qualifier.
        o  Continuous monitoring of a process with a single keystroke
           deletion feature:
           $ PSTAT /CONTINUOUS /USERNAME=SMITH /TYPE=INTERACTIVE
  	   If there is a single process matching the specified
           characteristics, PSTAT will enter the continuous update mode.
           CTRL-D may be used to delete the currently displayed process,
           if the user who activated PSTAT has sufficient privilege to
           stop the process.
	o  Deletion of multiple processes with similar characteristics:
           $ PSTAT /NODE=* /BEFORE=YESTERDAY /RATIO=LESS_THAN=0.01 /DELETE
           PSTAT will display and attempt to delete processes that were
           created before YESTERDAY with the connect to CPU time ratio
           less than 0.01 on all nodes in the cluster.  The program will
           ask for the confirmation from the user for every deletion
           operation and output log messages indicating the status of the
           deletions.
           $ PSTAT /TYPE=DETACHED /PROCESS=SSV$LTA* /DELETE /NOCONFIRM
           The program will display and attempt to delete all matching
           processes as well as output log messages indicating the status
           of the deletions.
        o  Quick detection and deletion of run-away processes by
           using the CPU time to connect time ratio and the continuous
           update mode.
Version 2.1 was posted to vmsnet.sources.  It is also available from 
Hunter Goatley's FILESERV and ftp site.  If you have any questions,
comments, or suggestions about PSTAT, please feel free to e-mail me.
