critical impact:

cluster-specific socket options - not available; potential enhancement (CrUn133)

CLU Impacts NW Impacts

Problem description

Cluster-specific socket options accessed using the setsockopt and getsockopt calls exist only on Tru64 UNIX, but not on HP-UX.

The following socket options are not available on HP-UX:

  • SO_CLUA_DEFAULT_SRC - Reports whether the socket will use the default cluster alias as its source address.

  • SO_CLUA_IN_NOALIAS - Reports whether the socket can only receive packets addressed to this cluster member.

  • SO_CLUA_IN_NOLOCAL - Reports whether the socket must receive packets addressed to a cluster alias and will drop any packets that are not addressed to a cluster alias.

  • SO_RESVPORT - Reports whether an attempt to bind the socket to a port in the reserved range (512-1024) will fail if the port is marked static.

  • SO_REUSEALIASPORT - Reports whether the socket can reuse a locked cluster alias port.
