CPS Scheduled Processes

Introduction
============

The following section is a list of the current scheduled processes running within the CPS system.

Module Sync
-----------
The module sync is a user :ref:`configurable timed process<additional-cps-ncmp-customizations>`,
which is set to search for CM-Handles within CPS with an *'ADVISED'* state.
Once the CM-Handle is processed by the module sync, the CM-Handle state is then set to *'READY'*, if the process completes successfully.
If for any reason the module sync fails, the CM-Handle state will then be set to *'LOCKED'*,
and the reason for the lock will also be stored within CPS.
CM-Handles in the *'LOCKED'* state will be retried when the system has availability. CM-Handles in a *'LOCKED'*
state are processed by the retry mechanism, by setting CM-Handle state back to *'ADVISED'* so the next sync cycle will process those again.

Data Sync
---------
The data sync is a user :ref:`configurable timed process<additional-cps-ncmp-customizations>`,
which is set to search for CM-Handles with a sync state of *'UNSYNCHRONIZED'*.
Once the CM-Handle(s) with a sync state of *'UNSYNCHRONIZED'* is processed by the data sync,
the CM-Handle sync state is then set to *'SYNCHRONIZED'*, if the process completes successfully.
If the data sync fails, the CM-Handle sync state will remain as *'UNSYNCHRONIZED'*, and will be re-attempted.
