3.2.6.8 ndb_mgm_restart3()

Description.  Like ndb_mgm_restart2(), this function can be used to cause an initial restart, waiting restart, and immediate (forced) restart on one or more Cluster data nodes. However, ndb_mgm_restart3() provides the additional options of checking whether disconnection is required prior to the restart.

Signature. 

int ndb_mgm_restart3
    (
      NdbMgmHandle handle,
      int          number,
      const int*   list,
      int          initial
      int          nostart,
      int          abort,
      int*         disconnect
    )

Parameters.  ndb_mgm_restart3() takes 7 parameters:

  • An NdbMgmHandle.

  • The number of nodes to be stopped. Use 0 to stop all of the data nodes in the cluster.

  • A list of the node IDs of the nodes to be stopped.

  • If initial is true (1), then each node undergoes an initial restart—that is, its file system is removed.

  • If nostart is true, then the nodes are not actually started, but instead are left ready for a start command.

  • If abort is true, then the nodes are forced to restart immediately without performing a graceful restart.

  • If disconnect returns 1 (true), this means the you must disconnect before you can apply the command to restart. For example, disconnecting is required when stopping the management server to which the handle is connected.

Return value.  The number of nodes actually restarted; -1 on failure.
