Aix hacmp cluster question (oracle & sap)

I'm glad to hear this. 
So you need information about HACMP monitors and how to combine them with a run-time policy. A monitor watches out for the existance of a certain process and uses your scripts to react if the process is not there/disappears. Then there are the following run-time Resource Group dependencies available from HACMP 5.3 on:However from the information you supply it would be hard to give detailed information how to setup the RGs. I suggest you check with the cluster docs about how to configure process monitors and custom monitors. Secondly read about the difference between startup monitoring mode and long running mode or the combined monitor that will check both start and runtime. Only monitors and scripts you define/write will ensure that the DB/app will start up in the order you wish.

I want to start HACMP but it should be in sequence.
I have 3 servers:
SAP Application services are running on 2 servers and Database is running on one of the servers..
So, the question was:
I want HACMP to start the Database server node B first, then it should join in the cluster the application server nodes A,C ;
It can be done by the start-stop script as you mentioned...But i was wondering if there any other way to do it in HACMP ?
Something called Startup Policy / home node online / parent - child dependencies / application monitoring ?[...]

- Bring parent online before or after child.
- Bring parent online on same node / different node / same site.

I have troubles making clstat work. All the "usual suspects" have been covered but still no luck. The topology is a two-node active/passive with only one network-interface (it is a test-setup). The application running is SAP with DB/2 as database. We do not use SmartAssists or other gadgets.
