Which background process of a database instance, using Automatic Storage Management
(ASM), connects as a foreground process into the ASM instance?
A.
ASMB
B.
PMON
C.
RBAL
D.
SMON
Explanation:
ASMB (ASM Background Process): Communicates with the ASM instance, managing
storage and providing statistics, runs in ASM instances when the ASMCMD cp command
runs or when the database instance first starts if the server parameter file is stored in ASM.
ASMB also runs with Oracle Cluster Registry on ASM.
RBAL (ASM Rebalance Master Process): In an ASM instance, it coordinates rebalance
activity for disk groups. In a database instances, it manages ASM disk groups.
PMON (Process Monitor): Monitors the other background processes and performs process
recovery when a server or dispatcher process terminates abnormally.
SMON (System Monitor Process): Performs critical tasks such as instance recovery and
dead transaction recovery, and maintenance tasks such as temporary space reclamation,
data dictionary cleanup, and undo tablespace management
