Throttling Dispatched Messages Through the Messaging System
You can throttle the number of dispatched messages from a given dispatcher to its associated handler(s).
Throttling the messages that pass through the messaging system enables you to avoid Tuxedo queue saturation due to redundant Tuxedo calls, which result in degraded performance.
You can throttle messages on any of the three pub/sub dispatchers:
PSBRKDSP
PSPUBDSP
PSSUBDSP
To set up dispatcher throttling, you must set the following parameters located in PSADMIN:
Tuxedo Queue Status Check Count
Dispatcher List Multiplier
Dispatcher Queue Max Queue Size
Information for setting these parameters is described earlier in this PeopleBook.
