configuring a stream object is the
second part of building a functioning
stream in the data stream designer this
video will demonstrate how to access the
configuration blade and explain several
of its functionality quirks to access
the configuration blade select a stream
object and click the configuration
command you can also double-click a
stream object the configuration blade
will open and display the save settings
of the stream object however newly
created stream objects cannot be
configured as they have not yet been
saved and a warning will appear to
remind you to save your stream if you
try in addition many stream objects ask
objects further up the stream for the
properties they will output when
determining options in their
configuration if you have altered the
connections or the configuration of
these objects but not yet save them the
old configuration settings will still be
used
therefore it is usually best to save
your stream every time you alter
configurations or whenever you finish
rearranging the stream the settings
displayed in the configuration blade
depend on the agent your stream object
was created from for instance the event
simulator agent needs to know the
properties of the events it will
generate and how often while the SQL
listener agent requires information
about the instance of SQL server that it
is to connect to more information about
each agents configuration will be found
within their documentation for now we
will use the SQL listener as an example
notice that whenever the server field
changes the configuration blade loads
briefly not all settings will do this
only certain ones depending on the agent
usually pertaining to login details or
uploading a file this is because such
settings affect the options displayed in
other settings so the entire blade must
be recreated using the new value for
instance when the correct login details
are supplied the agent will be able to
fetch the list of databases and populate
the database setting this can even
change which settings are shown for
example the password field is only
needed if the SQL authentication
checkbox is ticked therefore it will
hide or display accordingly whenever
that value changes also note that the
password field hides its contents and
even appears to change them after a
brief delay
this is normal it is because the
password setting is secure meaning that
the value you enter will be hidden from
view and will and the value will be
encrypted until it is needed by the
stream object finally note that the
blade offers the ability to discard and
apply your settings this card resets the
configuration to the value stored in the
designer while apply since the settings
you have entered back to the designer
and modifies the stream object to use
the new settings these changes can then
be discarded or permanently saved on
that blade agent configuration also
plays a part in assigning remote
configuration it is accessed by the
configure button under the remote
receiver or remote publisher if they
have been assigned and otherwise works
exactly the same way as in the designer
this has been how to configure a stream
object in the data stream designer thank
