Only API processes may use this  Any host  entry . Adding processes.  To add a new process to a given host, either right-click that host’s entry in the tree, then select the  Add process  popup when it appears, or select a host in the process tree, and press the Add process  button below the process tree. Performing either of these actions opens the add process dialog, as shown here: Here you can select from among the available process types described earlier this section; you can also enter an arbitrary process name to take the place of the suggested value, if desired. Removing processes.  To delete a process, select that process in the tree and use the  Del process button. When you select a process in the process tree, information about that process is displayed in the information panel, where you can change the process name and possibly its type. You can change a multi-threaded data node ( ndbmtd ) to a single-threaded data node ( ndbd ), or the reverse, only; no other process type changes are allowed.  If you want to make a change between any other process types, you must delete the original process first, then add a new process of the desired type . Like the  Define Processes  screen, this screen includes a process tree; the  Define Parameters  process tree is organized by process or node type, in groups labelled  Management Layer ,  Data Layer ,  SQL Layer , and  API Layer . An information panel displays information regarding the item currently selected.
