In the System Directory field, type c:\HA\GREEN.
Clear the Create TS3270 listener option.
In the Configuration Information field, type the following:
```
[ES-Environment]
ES_HA_VSAM=Y;RED,localhost,9045,86;GREEN,localhost,9046;BLUE,localhost,9047

Click Add.
Repeat this process for another server named BLUE, specifying the system directory as c:\HA\BLUE on Windows platforms.
