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).
To check to see if
nscd is set to load when the system is restarted, enter the command chkconfig --list nscd. For example:
# chkconfig --list nscd
nscd 0:off 1:off 2:off 3:on 4:off 5:off 6:off
nscd is turned on for run level 3, and turned off for run level 5. The nscd should be turned on for both run level 3 and run level 5.
To change the configuration to ensure that nscd is on for both run level 3 and run level 5, enter the following command as root:
# chkconfig --level 35 nscd on
To start up nscd in the current session, enter the command as root:
# service nscd start
To restart nscd with the new setting, enter the following command as root:
# service nscd restart
For Oracle Linux 7, verify that
nscd is enabled as follows:systemctl --all |grep nscd
