Identifies an available secondary link to the standby database.

    Applicable to:              Master database
    Required or Optional:       Optional
    Default Value:              None

    The Alt_Remote_Node qualifier is used to provide the master
    database with uninterrupted hot standby replication in case of
    network failure where multiple network links are available. It
    can only be used in conjunction with the Standby_Root qualifier,
    which specifies the standby database node name.

    The Alt_Remote_Node qualifier identifies the alternate remote
    node name of the standby database. Following network failure,
    the master database automatically attempts to reconnect to
    the standby database using the alternate remote node name
    information. If the Alt_Remote_Node qualifier is not specified,
    the master database does not automatically attempt to reconnect
    to the standby database using the orginal remote node name
    specified using the Standby_Root qualifier.

    The alternate node name can be the same as the node name
    specified with the Standby_Root qualifier. The node name
    specified by the Alt_Remote_Node qualifier must identify the
    same standby database on the same remote node as originally
    specified using the Standby_Root qualifier. The maximum length
    of the alternate remote node name is 31 characters.

    At run-time, the RDM$BIND_HOT_NETWORK_ALT_NODE logical name
    can be defined in the LNM$SYSTEM_TABLE table to override any
    alternate remote node name information specified at hot standby
    startup. The logical must be specified on all nodes where the
    master database is open.
