Configure the OPENDAP_BES service.
Open the Data Access GUI; in the "Service Configuration" tab, click the "Add New Service" button.
Configure the new service as follows:

 Service Name: OPENDAP_BES
Description: Service that bypasses the OLFS to access the Back-End Server directly.
Request Type: Both
Max Async Jobs: 10
Max Sync Jobs: 10
Timeout (Sec): 3600
Host: <Host>:<Port>
URL/Srv Path: /usr/ecs/<MODE>/CUSTOM/bin/DPL/BesService
[_] Enable Spatial Subsetting
[_] Enable Temporal Subsetting
[X] Enable Band Subsetting

SELECT * FROM AmDaService WHERE name = 'OPENDAP_BES';

Configure data_objects/parameters for the collection.
 

EcDlDaOpendapParmCfg.rb --mode <MODE> --host-fqdn <HOST> --esi-port <PORT> --collection <SNVI/ESDT> --output-dir <WRITABLE_DIR>
 

The output will be a URL; copy it; in a browser, log into the Data Access GUI; paste and visit the URL.
Use the query:

SELECT procdagetallobjflddimbands('<SHORTNAME>', <VERSIONID>, 'OPENDAP_BES');

to verify that at least two bands exist for the collection.
