Automatic memory management is enabled by default on an 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.
