This chapter describes a sample Oracle Solaris Cluster data service, HA for DNS, for the in.named application. The in.named daemon is the Oracle Solaris implementation of the Domain Name Service (DNS). The sample data service demonstrates how to make an application highly available, using the Resource Management API.
The Resource Management API supports a shell script interface and a C program interface. The sample application in this chapter is written using the shell script interface.
This chapter covers the following topics:
