Re: Domino Clustering (was Re: Trying to add Admin group tomailfilesACL and running out of time)

It's not hard to set up.

Yes you can cluster between differing platforms.  (Why would you want to? 
:-)    )

We have several iSeries running Domino.  We bring the primary down every 
night to do backup.  We bring the secondary down during the day on 
Thursdays to do a weekly save/rclstg/ipl.  It's freaking amazing how 
seamless this is!  I bet there is no other iSeries High Availability 
vendor who comes even close.  On the primary we have 8 Domino partitions. 
Each partition is in a separate cluster.  On the secondary is a matching 
partition.

Primary    Secondary    Cluster
NOTES01    NOTES02      NOTESCLUSTER
GDDATA     GDDATA2      GDDATACLUSTER
...

I would read the standard Domino documentation, and the Domino for iSeries 
documentation on doing this.

I don't know if there is a redbook dealing with an actual case study.

The toughest is making sure that if you create a database on the primary 
that you remember to replicate it to the secondary.  That is THE biggest 
reason that we purchased the akornn software.  800+ users with any 
turnover at all and the mail files alone are a maintenance headache.

Now, granted occasionally a file gets corrupted (and I have a long 
standing pmr opened on this).  But it sure is a lot easier to blast the 
file on the primary and replicate it back over from the secondary than it 
is to dig out the backup tapes.  It takes an average of 3 hours to restore 
a single mail file from tape.  Of course, our Domino backup alone spans 
onto the fourth 3590 tape (green button).  We find ourselves rearranging 
the ifs SAV to get the directory most likely to need restored done first.

Rob,

Sounds like you're doing Domino clustering.  I have a couple of questions:

1.  Can you cluster Domino servers on different platforms (i.e. OS/400 &
Windows 2K), or do they all have to be on the same platform?
2.  Is it difficult to set up?  Can I do it myself, or should I bring in 
an
expert?
3.  If it's not difficult to set up, where can I find documentation on
setting this up?

Thanks for the tip on the software.  Just the ACL manager by itself would
probably be worth it.

Mike E.

Buy this package:

Works great, and I believe that it is absolutely essential if you want to
make sure files exist on multiple servers in a cluster environment.
