TIBCO EMS STEP-5 :Destination Features
Ø EMS Destination
Features :
o Set a secure mode for
access control at the queue or topic level, so that some destinations may
require permission and others may not.
o Set threshold limits
for the amount of memory used by the EMS server to store messages for a topic
or a queue and fine-tune the server’s response to when the threshold is
exceeded.
o Route messages sent to
destinations to other servers.
o Create bridges between
destinations of the same or different types to create a hybrid messaging model
for your application. This can be useful if your application requires that you
send the same message to both a topic and a queue.
o Control the flow of messages
to a destination. This is useful when message producers send messages much
faster than message consumers can receive them. For more information on flow
control.
o Exchange messages with
other message services, such as TIBCO FTL, TIBCO Rendezvous, and TIBCO Smart
Sockets. Queues can receive messages from any of these services. Topics can
either receive or send messages.
o Set queues to be
exclusive or non-exclusive. Only one receiver can receive msg from an exclusive
queue. More than one receiver can receive msg from non-exclusive queues.
o Specify a redelivery
policy for queues. When messages must be redelivered, you can specify a
property on the queue that determines the maximum number of times a message
should be redelivered.
o Trace and log all
messages passing through a destination
o Include the user name
of the message producer in the message.
o Administrator
operations can use wildcards in destination names. The wildcard destination
name is the parent, and any names that match the wildcard destination name
inherit the properties of the parent.
o Use the store property
to cause messages sent to a destination to be written to a store file. Set the
destination store to store=$sys.failsafe to direct the
o Server to write
messages to the file synchronously and guarantee that messages are not lost
under any circumstances.
o Specify that a consumer
is to receive batches of messages in the background to improve performance.
Alternatively, you can specify that queue receivers are to only receive one
message at a time.
