Hi,
You can increase your database a hundred(maybe even a thousand), times
bigger without suffering
performance problems.
In the Admin guide the space occupied by each object (30Million of them), is
explained.
You will definately need to increase your db size.

Hi Riaan,
TSM does treat the cluster resources correctly - making it cluster aware, as
far as my requirements go.
Although you load the TSA with the /cluster=off it is cluster aware and will
treat
the disks as logical units and treat fail-over to the other nodes in the
cluster
correctly.

Hi Eric,
You will not get better performance than that - although, like Richard says,
it is common on all platforms it is worse on Netware.
You should definately switch off compression if you had it on - the reason
you are getting worse performance(this is my opinion anyhow), is because

you're talking about anyway.
And you mean LZ (Lempel-Ziv) algorithm, don't you :-?

Hi,
I see you are a Tivoli certified consultant (TSM) - maybe they missed that

the certification exam - why don't you read up on compression - if this

Does it tell the schedule did run at 02:41 for sure
or is this only a probable explanation?
regards

-----Ursprünglich
Simple answer - the fact that the schedule actually ran means there IS an
association - the fact that it does not run at the set time has to do with
the schedule randomization % that is set on the TSM server and the length of
the start-up window for the schedule for this client.
Simple example:
