Re: [Linux-cluster] Cluster for DB2 database



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.

regards,
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
