even of establishing contact with the partner. Current channels have
current status and might also have saved status.
The term Active is used to describe the set of current channels which are
not stopped.
Inactive channels
These are channels that either:
v Have not been started
v On which a client has not connected
v Have finished
v Have disconnected normally
(Note that if a channel is stopped, it is not yet considered to have finished
normally – and is, therefore, still current.) Inactive channels have either
saved status or no status at all.
There can be more than one instance of the same named receiver, requester,
cluster-receiver, or server-connection channel current at the same time (the
requester is acting as a receiver). This occurs if several senders, at different queue
managers, each initiate a session with this receiver, using the same channel name.
For channels of other types, there can only be one instance current at any time.
For all channel types, however, there can be more than one set of saved status
information available for a given channel name. At most one of these sets relates to
a current instance of the channel, the rest relate to previously-current instances.
Multiple instances arise if different transmission queue names or connection names
have been used in connection with the same channel. This can happen in the
following cases:
v At a sender or server:
– If the same channel has been connected to by different requesters (servers
only)
– If the transmission queue name has been changed in the definition
– If the connection name has been changed in the definition
v At a receiver or requester:
– If the same channel has been connected to by different senders or servers
– If the connection name has been changed in the definition (for requester
channels initiating connection)
The number of sets which are displayed for a given channel can be limited by
using the XMITQ, CONNAME, and CURRENT parameters on the command.
(generic-channel-name)
The name of the channel definition for which status information is to be
displayed. A trailing asterisk (*) matches all channel definitions with the
specified stem followed by zero or more characters. An asterisk (*) on its
own specifies all channel definitions. The channels must all be defined to
the local queue manager.
XMITQ(q-name)
The name of the transmission queue for which status information is to be
displayed, for the specified channel or channels.
This parameter can be used to limit the number of sets of status
information that is displayed. If it is not specified, the display is not
limited in this way.
