Explanation/Reference:
Section: Database Architecture & Resource Management, RAC, ASM
The ASMB process of a database instance, using ASM, connects as a foreground process into the ASM
instance. This ASMB process is responsible for the communication between the database and the ASM
instance.
The process monitor (PMON) process does not connect as a foreground process into the ASM instance. The
PMON process cleans up failed user processes and frees up all the resources used by the failed processes.
The RBAL process does not connect as a foreground process into the ASM instance. The RBAL process is new
background process of an ASM instance, and this process coordinates rebalancing activity for disk groups.
The system monitor (SMON) process does not connect as a foreground process into the ASM instance. The
SMON process performs instance recovery at database start up by using the online redo log files.
