- Organization of this page
Function
The Dispatcher (PD_PDDS) record stores performance data indicating the status of dispatcher processes at a specific point in time. To collect this record, you must have a multi-thread server (MTS) configuration.
PFM - Agent for Oracle creates one record for each dispatcher in an instance. This is a multi-instance record.
