Meaning of lock count and locking? (take II)

» close window

The Question is:

 
Would you define what Enq/Deq is from the Monitor Cluster/ALL monitoring
 utility. State if it is IO or process information.
 
Thank You...
 
 


The Answer is :

 
  MONITOR LOCK and particularly MONITOR DLOCK provide rather more direct
  (and detailed) access to the locking information that is visible via
  commands such as MONITOR CLUSTER/ALL.
 
  Please see topic 5270 for some background on locking, and on the $ENQ
  and $DEQ system services.  This locking information is not particularly
  process activity nor I/O activity, it provides some statistics on the
  current level of coordination activity within the OpenVMS distributed
  lock manager (DLM).
 
  Relevent documentation on the DLM includes:
