/SOCKET_RECEIVE=n

    Sets the socket's receive buffer size (in bytes) for the IP BUS. The
    default value is 178432 bytes, which is 128 times the maximum buffer
    size on an IP Channel. 'n' can be a value between 0 and 137035776. To
    reset the socket buffer size for the IP bus, set 'n' to 0. If the
    management provided value is lesser than the initial default, it is
    ignored.

                                 NOTE

       The maximum socket buffer size is limited by tcpip configuration
       and by default it is 1MB. It can be obtained by the following
       command:

         $ tcpip sysconfig -q socket sb_max

       To increase the size of IP bus' receive socket buffer beyond
       1MB, sb_max parameter has to be increased. Refer to "HP TCP/IP
       Services for OpenVMS Tuning and Troubleshooting" for information
       on changing sb_max.
