NAME

       nodename - local source for system name

SYNOPSIS

       /etc/nodename

DESCRIPTION

       When  a	machine is standalone or its IP address is configured locally, the /etc/nodename file contains the system name. By convention, the
       system name is the same as the hostname associated with the IP address of the primary network interface, for example, hostname.hme0.

       If the machine's network configuration is delivered by the RPC bootparams protocol, the /etc/nodename file is not used, as the system  name
       is delivered by the remote service.

       Given a system name value, regardless of source, the uname utility invoked with the -S option is used to set the system name of the running
       system.

       If the machine's network configuration is delivered by the DHCP protocol, the /etc/nodename file is used only if the DHCP server  does  not
       provide a value for the Hostname option (DHCP standard option code 12).

       A system name configured in /etc/nodename should be unique within the system's name service domain in order to ensure that any network ser-
       vices provided by the system will operate correctly.

       Given a system name value, regardless of source, the uname utility invoked with the -S option is used to set the system name of the running
       system.

EXAMPLES

       Example 1 Syntax

       The syntax for nodename consists of a single line containing the system's name. For example, for a system named myhost:

	 myhost

NAME

       scha_cluster_getnodename - local cluster node name access function

SYNOPSIS

       cc [flags...] -I /usr/cluster/include file -L /usr/cluster/lib  -l  scha
       #include <scha.h>

	scha_err_t scha_cluster_getnodename(char **nodename);

DESCRIPTION

       The  scha_cluster_getnodename()	function returns the name of the cluster node on which the function is called. The node name is not neces-
       sarily the same as the Solaris system name. The function returns an error status, and if successful, a string that contains the	node  name
       in the location that is pointed to by the nodename argument.

       If  the	call  fails,  the  nodename is set to NULL. The caller of scha_cluster_getnodename() is responsible for freeing the memory that is
       allocated for the returned string by using the standard C library function free(3C).  Freeing the memory is required only if  the  function
       succeeds.

RETURN VALUES

       The scha_cluster_getnodename() function returns the following values:

       0		   The function succeeded.

       nonzero		   The function failed.

ERRORS

       SCHA_ERR_NOERR			   Function succeeded.

       See scha_calls(3HA) for a description of other error codes.

EXAMPLES

       Example 1 Using the scha_cluster_getnodename() Function

	       scha_err_t  err_code;
	      char *nodename;
	      err_code = scha_cluster_getnodename(&nodename);
	      ...
	      if (nodename != NULL) free(nodename);
