Does anyone know what the maximum number of savesets is per group in
Networker 7.4.4 on Windows ?
Per group there is none, as the savesets are defined in the client
resources, and the group will run the clients and their savesets as
appropriate.
If you're referring to the number of savesets that can be used for a
client, it's not a hard and fast rule. If you're not using 'All' and
you're explicitly specifying savesets, the number will depend on the
size of the resource field - there's a hard limit, which has grown
over time. For instance, it used to be 1KB, it may now be bigger.
If you're referring to maximum number of savesets that can be active
at any one time, you're probably needing to evaluate parallelism.
There's some good stuff in the performance tuning guide and PowerLink,
and I also have a blog posting summarising the various aspects of
parallelism that may be useful as well. It's at:
http://nsrd.wordpress.com/2009/02/17/basics-parallelism-in-networker
That posting gets a lot of traffic, so obviously some people find it
useful.
The actual final limits to the number of savesets run by a group will
be server parallelism. You can limit at the group using savegroup
parallelism, but that's more something to use when you have multiple
overlapping groups, etc.
Cheers,
Preston.
