Scheduled Synchronization Flow
The following paragraphs describe how components of AutoSYNC interact to manage
and execute scheduled synchronizations:
Monitor Process
ASYSYNCP process
ASYSYNC process
Variant for Synchronization over TCP/IP
Monitor Process
The monitor process accesses the SYNCUSER table to determine the users that have
been configured by the administrator. Each user has various parameters such as
maximum priority. A user may be suspended, in which case it is ignored.
For each user ID, uuu,ggg, there should be a file set configuration table named
SFggguuu. All file sets in these tables are fetched to the monitor’s memory and sorted.
Suspended file sets are discarded.
The monitor starts a local ASYSYNCP process for each unique combination of user ID,
known destination system, and batch ID. If a destination system is not available, the
monitor waits for a system message that declares that the remote system is available,
and then starts the appropriate processes.
After starting the ASYSYNCP processes, the monitor sends a message to each
process, containing all file sets that pertain to that process.

Note. Disabling log down simply prevents use of another user ID by the Super user. The
Super user still has unfettered access to all data on the system. Using a privileged ASYSYNCP
to bypass disabled log down does not compromise data security.
