[Veritas-bu] Making use of 6.5.2+ default priorities in the presence of pre-existing policy priority settings
2009-02-04 12:26:49
In my environments, there are already some policy priority settings in place.
For the most part, I would like to clear those and make use of default
priorities... but I'm hazy on what "clear" means.
The bpplinfo man page says:
-priority priority
The priority of this policy in relation to other policies.
Priority is greater than or equal to 0. This value
determines the order in which policies are run. The higher
the value, the earlier the policy is run. The default is 0,
which is the lowest priority.
And the 6.5.2 documentation update says (on page 369):
bpplinfo Use the -priority option to specify a new priority for the backup
job that overrides the default job priority.
Has anyone yet determined empirically whether a priority setting of 0 (which is
the default if no priority is specified with bppolicynew) on the policy is a
special case that means "use the default" rather than "override the default",
even if the priority was previously set to a higher number?
The 6.5.2 documentation update also mysteriously refers to a "first" and
"second" priority in the "Understanding the Job Priority setting" section (on
page 358):
The NetBackup Resource Broker (NBRB) maintains resource requests for jobs in
a queue. NBRB evaluates the requests sequentially and sorts them based on the
following criteria:
* The request's first priority.
* The request's second priority.
* The birth time (when the Resource Broker receives the request).
The first priority is weighted more heavily than the second priority, and the
second priority is weighted more heavily than the birth time.
Has anyone sorted out what "first" and "second" mean here?
