Abstract

Assume a client-server calendar application that uses legacy applications like OfficeVision/VM* and OfficeVision*/MVS for its service and that has a graphical front-end running in OS/2* or DOS Windows**. Also, assume the design point for this application requires that some part of the server data is shadowed locally on the client for the end user to work with. This local data enhances performance and permits disconnected user support.

Calendar Synchronization for Multiple Users in Direct Connect Environment

       Assume a client-server calendar application that uses
legacy applications like OfficeVision/VM* and OfficeVision*/MVS for
its service and that has a graphical front-end running in OS/2* or
DOS Windows**.  Also, assume the design point for this application
requires that some part of the server data is shadowed locally on the
client for the end user to work with.  This local data enhances
performance and permits disconnected user support.

      Current* with OV/VM workgroup support is a good working model
of this kind of application, and it represents the state of the art
for this kind of "direct connect" application.

      The problem with the current solutions is that there is no way
to automatically synchronize the shadowed data with the server data
for calendars other than the user's own.  This becomes a problem for
people like secretaries who need to regularly review and update the
calendars of multiple people.  The secretaries are forced to refresh
the shadowed data manually to make sure they are not missing calendar
changes.

      In Current, the PC data and the host data are kept in sync by
automatically downloading the calendar data from the host to the PC
on regular intervals and modifying the PC data with the updates that
have been made to the host data.

      By changing the calendar synchronization code and main data
structures, multiple calendars can be...
