RAC testing

hi

i made 2-node , 2-instances RAC
my question , how to test the RAC working, loadbalance, configuration , drop one node and see the results (i.e RAC testing) ??
is there sql-scripts or certain senarios??

Thanks

you can use the swingbench tool this puts load against the DB and you can then pull the cluster to bits and see the impact or not to the back end. Nice tool
