Is there any way of specifying a relative value?  Say "starttime +30"

I guess it couldn't be after amdump starts because the estimate and
planning stage varies in length.


To solve the problem of prioritizing the order of certain dumps,
"starttime" (even with a relative time) is just a kludge, I believe.

I wonder why people would like to specify the order.
The reason I wanted it was to fill my tapes to 100%, and for the
taperalgo to work well, the larger dumps should be taped first.
Otherwise, you end up with all small dumps being finished and taped
already, filling the tape just enough so that any of the larger
dumps does not fit anymore, wasting a lot of tape (and time).

Maybe we need another directive for dumptype like "order {first|last}",
so that you can specify certain dumps to be started first, and others
to be started last; all the rest in between.  (Up to "inparrallel" dumps
can be started "first".)

What I also would like to see is to schedule certain DLE's close to
each other (e.g. because they contain parts of a database that has to
stopped before dumping the first DLE and started after the last DLE --
don't extend downtime by scheduling other DLE's inbetween).
Maybe a directive "group" giving a name to each group.

And while Santa-Claus is listening, I would also like a directive to
execute some scripts at start and end of each "group" (a name of a
script which must be located on that client), possibly with arguments
provided on one (the first?) of the group members.

host.com.tv /oradata1 {
        comp-user-tar
        order first
        group db1 {
                atstart /usr/local/bin/dbstop PRD immediate
                atend   /usr/local/bin/dbstart PRD
                }
        }
host.com.tv /oradata2 {
        comp-user-tar
        group db1       # is a member of group named "db1"
        }

I know, Santa Claus does not exist...
But Stefan saves these mails, isn't it?
