Why each option
MMON is the background process responsible for periodically flushing in-memory performance statistics to the AWR repository on disk.
MMON (Manageability Monitor) captures periodic snapshots of performance statistics from the SGA and writes them to the Automatic Workload Repository (AWR) on disk at regular intervals. This data collection supports Oracle's self-managing capabilities including the Automatic Database Diagnostic Monitor (ADDM) and advisory framework.
Coordinating disk group rebalance activity in ASM is the responsibility of the RBAL (Rebalance Master) background process, not MMON.
Communication between the database instance and the ASM instance is handled by the ASMB (ASM Background) process, not MMON.
Dynamic memory management under Automatic Shared Memory Management is performed by the MMAN (Memory Manager) background process, not MMON.
