2706.0. "Alarms" by TROOA::BALDOCK (Chris Baldock) Tue Apr 07 1992 11:15

    
    A simple question ... how or where is the information stored that
    indicates what alarms are enabled or disabled?
    
    In the alarms manual it states that alarms can be enabled or
    disabled within the context of each DECmcc instance.  This implies
    that the information is stored locally to each process.
    
    However, the manual also states that on VMS, once a rule is enabled,
    it is enabled on the entire node as long as the enabling DECmcc process
    is running.  The manual goes on to show you how to enable rules in a
    batch job.
    
    How does enabling rules in a batch job make a connection with a
    DECmcc session that I open?
    
    Thanks for any info.

  Chris,

  The Rule 'Status and Counter' information is stored in-memory for the
  process which has enabled the Rules.  If you enable the Rules interactively
  this information is in the process which is running the FCL or Iconic Map
  interface -- and private to those processes.  That is, only from the
  process which has enabled a rule, can you view the Status & Counter
  information, and disable the rule.

  If you enable the Rules in batch (via the FCL interface), the information
  is private to the batch job.  You will not be able to disable the rule
  or view the Status & Counter Attributes.  You can, of course, stop
  the batch job which will stop all the rules.

  When the Rules in the Batch job declare events ..

	o Rule Fired
	o Rule Exception

  The events are sent to a 'pool' which may be accessed by *any* process
  on the system.  This is how the Notification FM/PM (Iconic Map) can 
  'see' when a rule has fired, and change the icon color.

  Does this help ?

2706.2Everyone into the "pool"TROOA::BALDOCKChris BaldockTue Apr 07 1992 14:067
    
    It helps a lot.  One more question.  What is the "pool"?  Is it
    global pages in memory or some other mechanism?
    
    Thanks.
