 16.3.4.8 MySQL Cluster Shared-Memory Connections
 ................................................
 
 Shared memory segments are currently supported only for special builds
 of MySQL Cluster using the `configure' parameter `--with-ndb-shm'. Its
 implementation will most likely change. When defining shared memory as
 the connection method it is necessary to define at least `NodeId1',
 `NodeId2' and `ShmKey'. All other parameters have default values that
 will work out fine in most cases.
 
 `[SHM]NodeId1'
 
 `[SHM]NodeId2'
      To identify a connection between two nodes it is necessary to
      provide the node identity for both of them in `NodeId1' and
      `NodeId2'.
 
 `[SHM]ShmKey'
      When setting up shared memory segments an identifier is used to
      uniquely identify the shared memory segment to use for the
      communication. This is an integer which does not have a default
      value.
 
 `[SHM]ShmSize'
      Each connection has a shared memory segment where messages between
      the nodes are put by the sender and read by the reader. This
      segment has a size defined by this parameter. Default value is 1MB.
 
 `[SHM]SendSignalId'
      To be able to retrace a distributed message diagram it is
      necessary to identify each message with an identity. By setting
      this parameter to Y these message identities are also transported
      over the network.  This feature is not enabled by default.
 
 `[SHM]Checksum'
      This parameter is also a Y/N parameter which is not enabled by
      default.  When enabled all messages are checksummed before put
      into the send buffer.  This feature enables control that messages
      are not corrupted while waiting in the send buffer. It is also a
      double check that the transport mechanism haven't corrupted the
      data.
