Answer» It copies redo LOG FILES to a designated storage device after a log switch has occurred. ARCHIVER processes are there only when the database is in ARCHIVELOG mode, and automatic archiving is enabled. An Oracle instance can have up to 10 Archiver processes (ARC0 to ARC9). The LGWR process starts a new ARCn process whenever the current NUMBER of Archiver processes is INSUFFICIENT to handle the workload.
