Yes, TDP for Apps products do not need too much B/A client. But they
desperately need the API client which comes only with B/A client. I do not
know will those clients be separated someday or not. And for now I think
about them as a one whole client (with TDP as a plug-in).
I presume that Query LICenses contains the number of purchased licenses and
the number of nodes registered. And if I want for my own purposes to
register two nodes for the same box (would this be two B/A clients or B/A +
TDP) this would force me to pay more. Same if I want to put third drive in
a small library with 10 slots - I'll have to purchase Managed Library
license.
However both licencing schemes are very simplified. How can we distinguish
between two nodes on two machines, two nodes on the same OS and two nodes
on different OS images with the same box (HP SuperDome or IBM eServer
pSeries 690 for example)? Or should we consider whole IBM SP(2) cluster as
a single system with multiple nodes registered? Same for tape libraries -
for sure there is a difference between small 5-6 slot DDS4 autoloader and
IBM 3494 with 6 frames. But the question is how many categories to define
in this wide spectrum of devices.
As we see IBM/Tivoli preferred simplicity vs complexity.

P.S. And if these are not the correct licenses, put me on the copy too ,-)

Subject:        Re: Licensing MS SQL cluster - managed system for LAN/SAN
and TDP licenses?

The way I understand the licenses, you need either a Managed System for LAN
OR a Managed System for SAN license for each *Managed System* that you are
backing up (the SAN license permits you to backup files across the LAN).
Not for each node you register to TSM.

Assuming that only one of the cluster nodes in the example is backing up
the database across the SAN, you would need to purchase one LAN, one SAN
and one TDP license, even though you might wind up registering 4 nodes to
TSM (one for the base files on each system, one for the TDP files on each
system assuming you're following the instructions to place the TDP data in
a different domain).

The TDP for SQL product only requires the TSM BA client if TSM central
scheduling is used (see
http://www.tivoli.com/support/storage_mgr/tdp_ms.html#SQL).  So, if you
have another way to kick off the backup (at?) and you are not using the BA
client to back up your files, you don't need the Managed System for ?AN
license at all.

Check with Tivoli to be sure, but if somebody finds out this isn't correct,
let me know.

Zlatko,

If I understand your configuration correctly, you will have two
Windows systems running a clustered SQL server environment.
You want to back up of each of the Windows file systems over the
LAN and the SQL data over a SAN connection.
Thus, you will have 2 TSM nodes for the file system
data on each server and one TSM node for the clustered SQL server.

My understanding for the license requirements is as follows:

2 Managed system for LAN licenses
  (one for each node backing up the Windows file system)

1 Managed system for SAN license for the LAN-free support
  for TDP for SQL

1 TDP/SQL license if this is not an active/active cluster
  (which means the SQL server and thus TDP for SQL is only
  running on one of the clustered machines at a time)

To be certain, please confer with you Tivoli sales representative.

Thanks,

Del
