Larry.

We are (or, at least, will be) doing something quite similar. There seems
to be some confusion with your sources as to what ACSLS takes care of and
what ADSM takes care of. With ACSLS, mount and other library commands are
simply routed to a central machine. The internal library inventory is kept
track of by this central ACSLS database.

However, you will indeed need separate adsm servers for your database
application and "normal" clients. If you are talking about 2 different
databases on your two HP boxes, then you are indeed talking about 3
separate licenses.

As for management, 3.1.2 appears to take a big step in centralizing
monitoring and control, though the server databases remain separate.

I hope this answers your questions.

Subject:  STK ACSLS and ADSM




We are looking to share an STK 9710 SCSI library with 10 DLT 7000
drives. We understand that the ACSLS product from STK enables this.  We
will have   a dedicated ADSM server taking 3-4 of the drives for backing
up clients via a 100 Mb network.  We want to directly attach 2 large HP
servers that have Oracle databases > 200 GB to the STK library so that
we are not backing them up over the net, going directly to the tape
drives in the 9710 instead.

  I have heard from an IBM rep that we need to have ADSM server licenses
on these two HP servers, in addition to the ADSM server license for our
dedicated backup server,  and that these Oracle servers have their own
ADSM databases, manage their own media, etc.   Someone else told me that
the library is managed by the dedicated ADSM server via ACSLS and the
Oracle servers merely output to the tape drives in the library.

We are trying to create an environment that is easy to administer (who
isn't!) and works as simply as possible.   Does anyone have experience
with ACSLS in the Unix environment?  We will have either an AIX box or
Solaris system be the dedicated ADSM server.  Can you point me to any
IBM documentation that lays this out, along with licensing requirements?

Thanks!
