15Introduction
16============
17
18The following section is a list of the current scheduled processes running within the CPS system.
19
20Module Sync
21-----------
22The module sync is a user :ref:`configurable timed process<additional-cps-ncmp-customizations>`,
23which is set to search for CM-Handles within CPS with an *'ADVISED'* state.
24Once the CM-Handle(s) is processed by the module sync, the CM-Handle state is then set to *'READY'*, if the process completes successfully.
25If for any reason the module sync fails, the CM-Handle state will then be set to *'LOCKED'*,
26and the reason for the lock will also be stored within CPS.
27
28Data Sync
29---------
30The data sync is a user :ref:`configurable timed process<additional-cps-ncmp-customizations>`,
31which is set to search for CM-Handles with a sync state of *'UNSYNCHRONIZED'*.
32Once the CM-Handle(s) with a sync state of *'UNSYNCHRONIZED'* is processed by the data sync,
33the CM-Handle sync state is then set to *'SYNCHRONIZED'*, if the process completes successfully.
34If the data sync fails, the CM-Handle sync state will remain as *'UNSYNCHRONIZED'*, and will be re-attempted.
35
36Retry Mechanism
37---------------
38The retry mechanism is a user :ref:`configurable timed process<additional-cps-ncmp-customizations>`,
39which is used to search for CM-Handles which are currently in a *'LOCKED'* state.
40If the CM-Handle is ready to be retried then, the CM-Handle(s) in a *'LOCKED'* state is processed by the retry mechanism,
41the CM-Handle state is then set to *'ADVISED'*.
42Whether the CM-Handle is ready to be retried is dependent on both the number of attempts to sync the CM-Handle,
43and the last update time of the CM-Handle state.
44With each new attempt to unlock the CM-Handle, the time until the CM-Handle can next be retried is doubled.
