Change Control
Jobs
Every time you add, modify, or delete any object, this change is captured by the client
to either save or commit to the ISM Provision server. When you save or commit your
changes, this list of individual additions, modifications, and deletions is sent to the ISM
Provision server as a single entity called a job. A job may consist of a single change to
one device parameter or the addition of hundreds of configuration objects, but it is
saved or committed as a unit to the ISM Provision server. Once a job is committed, any
changes to the configurations of managed devices are sent to the devices using the
device communicator assigned to that device.
Different from a committed job is a saved job. A saved job is also stored in the ISM
Provision server, but its collection of changes are not sent out to the network, unless the
saved job is later committed. A scheduled job is a saved job that will automatically be
committed at a scheduled time. One of the options of the commit process is to do the
actual commit at a later time. Any job scheduled to be committed at a later time is
saved until the commit time, and then committed to the network.
If an error occurs while a job is being committed, and any of the changes that make up
the job cannot be committed, the entire job is rejected, and any parts of the job already
added are backed out. A committed job that causes an error is still listed along with
other committed jobs, but its status is listed as rejected. To correct the errors, view the
committed yet rejected job, and review the job results. You will see the details of the
problem that caused the error.
Any job can be viewed, whether committed, rejected, scheduled or saved. You can
review the individual objects that were created, modified, and deleted. You can also
review the results of the job to help you correct any errors that might have occurred.
Configuration Versions
A configuration version in Network Infrastructure Manager is a collection of all the
current configurations of all the devices in the ISM Provision server. At any time you
can create a configuration version, and later roll your network back to that state.
Typically, you would create a configuration version before you roll out new changes to
the network on multiple devices, so that you can go back to a known good state easily,
in case of difficulties.
