* BWnn There can be 1 to 100 Database Writer Processes. The names of the first 36 Database Writer Processes are DBW0-DBW9 and DBWa-DBWz. The names of the 37th through 100th Database Writer Processes are BW36-BW99. The database selects an appropriate default setting for the DB_WRITER_PROCESSES parameter or adjusts a user-specified setting based on the number of CPUs and processor groups.
* FENC (Fence Monitor Process) Processes fence requests for RDBMS instances which are using Oracle ASM instances
* IPC0 (IPC Service Background Process) Common background server for basic messaging and RDMA primitives based on IPC (Inter-process communication) methods.
* LDDn (Global Enqueue Service Daemon Helper Slave) Helps the LMDn processes with various tasks
* LGnn (Log Writer Worker) On multiprocessor systems, LGWR creates worker processes to improve the performance of writing to the redo log. LGWR workers are not used when there is a SYNC standby destination. Possible processes include LG00-LG99.
* LREG (Listener Registration Process) Registers the instance with the listeners
* OFSD (Oracle File Server Background Process) Serves file system requests submitted to an Oracle instance
* RPOP (Instant Recovery Repopulation Daemon) Responsible for re-creating and/or repopulating data files from snapshot files and backup files
* SAnn (SGA Allocator) Allocates SGA The SAnn process allocates SGA in small chunks. The process exits upon completion of SGA allocation.
* SCRB (ASM Disk Scrubbing Master Process) Coordinates Oracle ASM disk scrubbing operations
* SCRn (ASM Disk Scrubbing Slave Repair Process) Performs Oracle ASM disk scrubbing repair operation
* SCVn (ASM Disk Scrubbing Slave Verify Process) Performs Oracle ASM disk scrubbing verify operation
Happy Learning..!!
Cheers..!!
