Issue 2433:  CosNotification -- MaxEventsPerConsumer = 0 for infinity? (notif_service-rtf)
Source:  (, )
Nature:  Uncategorized Issue
Severity: 
Summary: Summary: The CosNotification spec is careful to say that, for the administrative
 properties (MaxQueueLength, MaxConsumers and MaxSuppliers), the default 
 value is zero, and it means that there is no limit.
 
 As far as I can see there is not similar wording for the QoS property
 MaxEventsPerConsumer.  Two questions that should probably be answered are:
 
       -	is there a magic value that means "no limit"?
 
       -	what is the default value if it"s not eqplicitly set at any level?
 
 I would suggest that, for consistency with MaxQueueLength, the magic value
 should be 0, and the default should be that same value.
 

Resolution: Added sentence to end of MaxEventsPerConsumer section of section 2.5.5
Revised Text: 
Actions taken:

November 16, 1999: closed issue
Discussion: 
Synopsis: The spec states that a 0 value for MaxQueueLength, MaxConsumers

          and MaxSuppliers means those QoS properties impose no limited on

          the entity they are intended to constrain. The is not similar

          wording for MaxEventsPerConsumer. The proposed resolution is to

          add similar wording for MaxEventsPerConsumer, making 0 be the

          default value meaning there is no limit on the number of events

          that can be queued per consumer.

  

Disposition: I agree with the issue and the proposed resolution



VOTE: YES means to add the recommended text; NO means to do nothing

The CosNotification spec is careful to say that, for the
administrative
properties (MaxQueueLength, MaxConsumers and MaxSuppliers), the
default 
value is zero, and it means that there is no limit.

As far as I can see there is not similar wording for the QoS property
MaxEventsPerConsumer.  Two questions that should probably be answered
are:

      -	is there a magic value that means "no limit"?

      -	what is the default value if it's not eqplicitly set at any
level?

I would suggest that, for consistency with MaxQueueLength, the magic
value
should be 0, and the default should be that same value.
