The NDB Cluster Auto-Installer (No longer supported) Figure 23.19 Define Parameters—Process Attributes Attributes whose values can be overridden are shown in the information panel with a button bearing a plus sign. This  +  button activates an input widget for the attribute, enabling you to change its value. When the value has been overridden, this button changes into a button showing an  X . The  X  button undoes any changes made to a given attribute, which immediately reverts to the predefined value. All configuration attributes have predefined values calculated by the installer, based such factors as host name, node ID, node type, and so on. In most cases, these values may be left as they are. If you are not familiar with it already, it is highly recommended that you read the applicable documentation before making changes to any of the attribute values. To make finding this information easier, each attribute name shown in the information panel is linked to its description in the online NDB Cluster documentation. This screen allows you to perform the following tasks: The  Deploy Configuration  screen is shown here: 4024 •Start and stop the cluster •Distribute configuration files by creating any necessary files and directories on all cluster hosts—that is, deploy  the cluster as presently configured •Review process startup commands and configuration files to be applied NDB Cluster Auto-Installer Deploy Configuration Screen
