I am not using RAC (to my knowledge), but I installed grid so I can use ASM with my RDBMS. Recently I noticed that the "CRS Listener" service was not started, when I try to start it then it immediately stops. It does not seem to affect the databases, they are still up and running. What is this service used for and how can I get it to start. I am using Oracle Enterprise Server 188.8.131.52 and Grid 184.108.40.206 on a Windows 2008 R2 64-bit server. Thanks in advance.
