V$LOGMNR_PROCESS identifies all processes attached to an active LogMiner persistent session. (A persistent LogMiner session is created either by starting Data Guard SQL Apply on a logical standby database for the first time or by creating Streams capture.) This view can be joined with either the V$SESSION view or the V$PROCESS view to gather process-specific information.
Unique identifier for the LogMiner persistent session
Oracle process identifier for the SQL Apply or Streams capture process (same as the V$PROCESS.PID)
Operating system process identifier (same as the V$PROCESS.SPID)
Identifies the role of the active LogMiner process: READER, PREPARER, BUILDER, COORDINATOR, or APPLY SERVER
Operating system process user name that is connected to the database
Session identifier for the V$SESSION.SID process
Session serial number associated with the V$SESSION.SERIAL process
Address of the latch the process is waiting for; NULL if none
This column is obsolete
