The NMS runs a single independent thread to clean up obsoleted : Clean-up occurs only in specified Day-Of-Week and Hour-Of-Day-Window.
Upon the start of a Clean-Up Window, a purge to each object type will be performed before applying their individual In-Between-Purge-Period. Since the purges of all object type are handle by this single Clean-up thread, the purges of the different objects are performed sequentially.
The Clean-Up Thread run at the resolution of the CDR's "CdrPurgePeriod", so any other object with Purge Period less then "CdrPurgePeriod" will run at the same frequency as the purge for the CDR.
Clean-Up ThreadParameters | Values | Default | Descriptions |
---|
CleanUpDayOfWeek | string | 0123456 i.e. every day | Constraint Clean Up to occur at specific GMT Days of the Week Match pattern (0..6, Sunday==0, Saturday==6) |

CleanUpHourOfDay | string | HIJK i.e. 7:00 to 10:59 GMT | Constraint Clean Up to occur at specific GMT Hour of the Day Match pattern (A..X, A==00,.. J==9,.. M==12,.. X==23) |
---|
CleanUpStartupDelay
| integer
| 300
| # Second to delay start of Clean-Up from system start-up to allow everything else to settle down
|
CDR Clean-UpCDR Purge size of 100K seem to cause call rate to drop and CDR OOP to increase. Whereas 10K or below seem to have little impact, and 2K or below should be pretty safe.
Parameters | Values | Default | Descriptions |
---|
CdrKeepDays | integer | 180
| days to keep CDR |

VMail Clean-UpV-Mail purge scans the trash folder of every subscriber, and sleeps for 10ms after each folder to release processing to other tasks. Therefore, it will take some time and hold up the purges for the other objects.
Parameters | Values | Default | Descriptions |
---|
TrashHoldDay | integer | 1 | # Days to hold deleted items in the trash folder before purging them permanently |
---|
VMailPurgePeriod
| integer
| 1440
| # Minute between V-Mail Purges
