| Description | The applPastChannelTable provides history information
about channels from the perspective of running
application elements and service instances.
Entries in this table are indexed by applElmtOrSvc,
applElmtOrSvcId, and by applPastChannelIndex, which
serves to uniquely identify each former channel in the
context of a running application element or service
instance.
Note that the value of applPastChannelIndex is
independent of the value applOpenChannelIndex had when
this channel was open.
Entries for closed channels for a given running
application element or service instance can
be added to this table only if its entry in the
applPastChannelControlTable has the value 'enabled'
for the attribute applPastChannelControlCollect.
Entries for closed channels are removed under the
following circumstances:
- the running application element or service
instance no longer exists
- the corresponding applPastChannelControlCollect
attribute has been set to 'disabled'
- the entry has been in the table longer that the
time limit indicated by the corresponding
applPastChannelControlTimeLimit and the value of
applPastChannelControlCollect is not 'frozen'
- this is the oldest entry for the running
application element or service instance in
question and the addition of a new element would
otherwise cause applPastChannelControlMaxRows to
be exceeded for this running application element
or service instance.
- a value of applPastChannelIndex has been re-used.
Note that under normal circumstances, this is
unlikely.
Removal/replacement of an entry under the
last two conditions causes the corresponding
applPastChannelControlRemItems to be incremented. |
