Hi,
HACMP seems to be, like RH-cluster, a active-pasive cluster:
http://www-03.ibm.com/systems/p/software/hacmp.html
So, you will not increase performance, just avaliability. If you want to
increase performance you should look for a cluster database like
MySQL-cluster or Oracle RAC. I don't know much about DB2, so I don't
know if there's a DB2-cluster.

Jordi

Hello Jordi,
Thanks for your comments.
Really, I was thinking about this hypothesis too but, I need to
improve the performance overall. Of course, HA is a implied concept on
that kind of Cluster.
GFS or HA-iSCSI, only will help me to consolidate the Database files
but wont give the growth in scale, that is what I'm looking for.
Our database partner is insisting to make us to use the IBM's HACMP
but, I'm not sure about this yet.
What do you thing ?

Hi,
I'm not a expert on DB2 but I don't think RHcluster will give you a
performance-oriented cluster of DB2 databases. Instead, I could
provide
you a HA database or a HA-iSCSI target or GFS for your datafiles.
Remember that if you share the same datafiles DB2 should be
cluster-aware.
By the way, Oracle RAC it's a cluster by itself, it does not use RH
cluster in any way.
Hope this helps.
regards,
Jordi
