@Marcus, I think was very clear that failover is configured through TSA, powerHA or MSFC.
@pgarciab, the redbook I mentioned earlier answers most -if not all- of your questions
IBM Redbooks | High Availability and Disaster Recovery Options for DB2 for Linux, UNIX, and Windows

If you have any of those cluster failover solutions, then you can use them on regular DB2 with one active server and one passive server, and therefore you don't need DPF.

@Marcus, I'll back to your previous post, each one is used for one specific purpose. Yes, you are absolutely right. However, that doesn't mean you can only use one single technology alone. You can combine both solutions for better availability. You can have a scalable environment and make the nodes of this environment highly available.

Hye
Did u try to configure an alternate server ?
U can do this by ctalogibg nodes on db2 connect server or in the data source config on web app server if a jdbc driver is used

@Dav_nac, yeah i think that can help can you show me how to do that? it would be nice.

Hye

Tell me more about your topology :

- Do you have sthg like a JDBC driver installed on application server (such as W.A.S)
- Is your db2 connect on the server than app° server or a distinct server?

any others informations are welcomed.

Waiting for your answer i can say i have already configured such a solution called "client reroute" (Make a search on internet). I had an AIX web app server with a IBM JDBC driver on it. I configured the JDBC provider on Websphere with a primary AIX db2 connect and an "alternate server" on an other AIX with db2 connect with the same databases alias.

Hope it will be helpfull

i need two active db2 servers to distribute the load for a bpm 7.5.1 databases, obviously need sincronized databases.
I installed several bpm environments using simple and remote topologies (non-productive) but it is the first time I need to install DB2 High Availability (productive environment) and im lost.

For DB2, pureScale is the only active-active cluster solution, unless you want to use something like replication to keep the servers in synch. DB2 pureScale is an extra cost feature on top of Enterprise Server Edition (ESE) and requires special hardware to work. Don't even think about trying pureScale yourself without some help or education.

When you say you have done this with bpm 7.5.1 databases, not sure what you are talking about, and it would help if you were more specific.

when I said about bpm what I meant was i configured it but using a simple db2 installation, in this occasion I asked for an active-active solution.

I realize now that pureScale is the only solution that db2 offers for active-active cluster.

Thanks for your answers.
