Connecting Calendar & Notes with GCCHN

You can use Google Calendar Connector for HCL Notes (GCCHN) to let users share calendar availability between Google Calendar and Notes. It’s ideal if you’re migrating to Google Workspace from HCL Notes, and you have users who want to view whether other Notes and Google users are available for meetings during the migration period.

How GCCHN works

GCCHN works by checking whether the following attendees are available:

  • Notes—When you add an attendee to a Google Calendar event, GCCHN contacts the Domino web service. It accesses the Notes busytime store and returns the information to Google. Using that information, you can view whether the Notes' attendee is available for a meeting.
  • Calendar—GCCHN contacts Google Calendar every hour to extract meeting information. Using that information, it updates the Notes systems with the Google data, and you can view whether the Calendar attendee is available for an event.

About the GCCHN components

Connector database

Contains the configuration information. It's made up of the following agents:

  • GetNotesFreeBusy—Responds to Notes availability requests from Calendar.
  • Update Calendars—Provides the polling service used for Notes-to-Google lookups. It does the following tasks:
    • Reads the Domino Directory and creates a profile for each user identified as using Calendar
    • Gets the Calendar availability information for each Google user
    • Writes the Calendar availability information to the Notes system

Log database

GCCHN logs events and actions completed by the connector agents and database. Log entries are purged after 7 days.

Service account DLL

If you authorize using a service account, the account's dynamic link library (DLL) is used. It's not required when authorizing through 3-legged OAuth.
