6.1.2 Setting Up the /etc/nsswitch.conf File

On each node that can master the logical host running Sun Cluster HA for Sybase, modify the /etc/nsswitch.conf file so that "group" lookups are directed to files first. For example:

...
 group: files nisplus
 ...

Sun Cluster HA for Sybase uses the su sybase command when starting and stopping the database server.

Adding these settings will ensure that the su sybase command does not refer to NIS/NIS+ when the network information name service is not available due to a failure of the public network on the cluster node.
