Is my RAC using SCAN properly ?

Hi,

We have 2 nodes RAC (11gR2) working properly(in general) but I need to verify if the SCAN is setup properly or not :

I did following :

[oracle@ora1a ~] export GRID_HOME=/u01/app/grid/11.2.0.4

[oracle@ora1a ~]  more /u01/app/grid/11.2.0.4/network/admin/listener.ora

LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER))))                                         # line added by Agent

LISTENER_SCAN3=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN3))))                # line added by Agent

LISTENER_SCAN2=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN2))))                # line added by Agent

LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1))))                # line added by Agent

Howdy, Stranger!
