Thomas Phan..this is the only db2 book available in india..There they
are talking about tablespace reblance when a new container is added to
a tablespace..I am not quite getting it..what does the DBA have to do
manually after her adds a container to a tablespace ..does he he have
to do soemthing manually for rebalance..what if i dont do any
reblalance ? will it effect performance

You don't have to do anything.
Just wait till the rebalance completes.

i think (but be not sure at the moment) that the DB has to be active
(either via ACTIVATE DATABASE or an open connection).
otherwise the rebalancing will not progress (as soon as there is a
connection the rebalancing will continue, nothing special to do for
the DBA)

Is there anything you can do to delay rebalancing until a slow period?

Either you delay the adding of the container that causes the rebalancing
or, if running at V8, you can use the alter tablespace command with
begin new stripe set option. This will not cause rebalancing to start
but your tblspace structure may not be optimal.
