IBM HACMP Failover Cluster

Former Member

Hi Experts,

I have implemented 2 Node Cluster installation as per IBM AIX-NW2004s-Java-Oracle10.2 installation guide.

Now Vendor has come here for IBM HACMP(Failover Software) installation and configuation.

These guys are telling that normally failover of SCS or DB takes more than 10 minutes,so Servers will not be available for 10 mins.

But I am sure that for SCS failover it should not take more than 2 mins and for DB-Failover it should not take more than 3 minutes.

1. Can anyone point me out any document/link to show these guys how to make ACTIVE - PASSIVE Cluster setup? (If possible on unix flavor)

2. Can anyone tell me why my APP Servers are getting restarted if my SCS is unavailable for some time?

3. How to accomplish the DB reconnect mechanism in only AS Java cluster failover implementation?

Any points would be highly appreciated.

Regards,

Karthick

Hello

New version of PowerHA have introduced new Smart Assist installation agents and startup/shutdown scripts by demand for SAP.

See note 1522360.

But IMHO PowerHA still worst solution for clustering SAP system.
