| 16 | Introduction |
| 17 | ============ |
| 18 | |
| 19 | The following section is a list of the current scheduled processes running within the CPS system. |
| 20 | |
| 21 | Module Sync |
| 22 | ----------- |
| 23 | The module sync is a user :ref:`configurable timed process<additional-cps-ncmp-customizations>`, |
| 24 | which is set to search for CM-Handles within CPS with an *'ADVISED'* state. |
| 25 | Once the CM-Handle(s) is processed by the module sync, the CM-Handle state is then set to *'READY'*, if the process completes successfully. |
| 26 | If for any reason the module sync fails, the CM-Handle state will then be set to *'LOCKED'*, |
| 27 | and the reason for the lock will also be stored within CPS. |
| 28 | |
| 29 | Data Sync |
| 30 | --------- |
| 31 | The data sync is a user :ref:`configurable timed process<additional-cps-ncmp-customizations>`, |
| 32 | which is set to search for CM-Handles with a sync state of *'UNSYNCHRONIZED'*. |
| 33 | Once the CM-Handle(s) with a sync state of *'UNSYNCHRONIZED'* is processed by the data sync, |
| 34 | the CM-Handle sync state is then set to *'SYNCHRONIZED'*, if the process completes successfully. |
| 35 | If the data sync fails, the CM-Handle sync state will remain as *'UNSYNCHRONIZED'*, and will be re-attempted. |
| 36 | |
| 37 | Retry Mechanism |
| 38 | --------------- |
| 39 | The retry mechanism is a user :ref:`configurable timed process<additional-cps-ncmp-customizations>`, |
| 40 | which is used to search for CM-Handles which are currently in a *'LOCKED'* state. |
| 41 | If the CM-Handle is ready to be retried then, the CM-Handle(s) in a *'LOCKED'* state is processed by the retry mechanism, |
| 42 | the CM-Handle state is then set to *'ADVISED'*. |
| 43 | Whether the CM-Handle is ready to be retried is dependent on both the number of attempts to sync the CM-Handle, |
| 44 | and the last update time of the CM-Handle state. |
| 45 | With each new attempt to unlock the CM-Handle, the time until the CM-Handle can next be retried is doubled. |
