Circuit (PD_PDCI)
- Organization of this page
Function
The Circuit (PD_PDCI) record stores performance data indicating the status of circuits 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 circuit of an instance. This is a multi-instance record.
