What is OraFenceService in windows for Oracle Grid?

The OraFenceService was introduced with the Oracle9i version of Real Application Clusters for windows platforms. The service is installed with the OracleCMService for Oracle9i and during the CRS installation for Oracle 10g.

In Windows environments, most services are displayed under Control Panel > Services.
However, the OraFenceService is only visible in the registry under HKLM > SYSTEM > CurrentControlSet > Services.

The corresponding files are "orafencedrv.sys" and "orafenservice.sys" located in WIN_HOME\System32\drivers directory.

This is a kernel mode service to provide I/O fencing. The service restarts a node in case the node hangs in kernel mode for a defined amount of time.

The service must be started or stopped in a command prompt window:

net stop orafenceservice
net start orafenceservice
