Enabling the Name Service Cache Daemon

To allow Oracle Clusterware to better tolerate network failures with NAS devices or NFS mounts, enable the Name Service Cache Daemon (nscd).

Starting with Oracle Solaris 11, when you enable nscd, nscd performs all name service lookups. Before this release, nscd cached a small subset of lookups. By default, nscd is started during system startup in runlevel 3, which is a multiuser state with NFS resources shared. To check to see if nscd is running, enter the following Service Management Facility (SMF) command:

# svcs name-service-cache
STATE          STIME    FMRI
online         Oct_15   svc:/network/nfs/status:default
online         Oct_30   svc:/system/name-service-cache:default

For Solaris 11, the SMF service svc:/system/name-service/cache contains the configuration information for nscd. The file /etc/nscd.conf is deprecated. Note that svc:/system/name-service-cache still exists on Solaris 11 systems but it is not connected.

If the nscd service is not online, you can enable it using the following command:

# svcadm enable svc:/system/name-service-cache:default
