Automatic memory management is enabled by default onan ASM instance, even when the
MEMORY_TARGET parameter is not explicitly set.
ASMB runs in a database instance that is using an ASM disk group. ASMB communicates with the ASM
instance, managing storage and providing statistics. ASMB can also run in the ASM instance. ASMB runs in
ASM instances when the ASMCMD cp command runs or when the database instance first starts if the SPFILE
is stored in ASM.
