This screenshot from the DBCA utility shows the Node Selection screen on which there is the following text: "Select the nodes for which you want to manage ASM diskgroups. The local node "stbdq18" will always be used whether or not it is selected. Then, in the center of the window, the nodes stbdq18 and stbdq19 are listed.
Both nodes are highlighted in blue to indicate they have been selected and the Next button at the bottom of the screen is outlined to indicate the user who is running the DBCA utility has clicked Next to continue to the next page of the GUI.
