+Test PCP interface (as root) :
+
+ #retrieves the node information
+ pcp_node_info 10 localhost 9898 postgres "postgres-pass" "postgres-id"
+ #detaches a node from pgpool
+ pcp_detach_node 10 localhost 9898 postgres "postgres-pass" "postgres-id"
+ #attaches a node to pgpool
+ pcp_attach_node 10 localhost 9898 postgres "postgres-pass" "postgres-id"
+
+After starting pgpool, try to test this two scenarios :
+
+**1. When a slave fall down** :
+
+Open pgpool log file 'tail -f /var/log/pgpool2/pgpool.log'.
+
+Stop slave node '/etc/init.d/postgres stop'.
+
+After exceeding health_check_period, you should see this log message :
+
+ [INFO] Slave node is down. Failover not triggred !
+
+Now, start slave failback process (as root) :
+
+ # ./online-recovery.sh
+
+**2. When a master fall down** :
+
+Idem, open pgpool log file.
+
+Stop master node '/etc/init.d/postgres stop'.
+
+After exceeding health_check_period, you should see this log message :
