Which statement is true about the Manageability Monitor (MMON) background process?
A.
It transfers statistics from memory to disk at regular intervals.
B.
It coordinates the rebalance activity for disk groups when ASM is used.
C.
It communicates with the Automatic Storage Management (ASM) instance on behalf of the
database instance.
D.
It performs dynamic memory management when Automatic Shared Memory Management is
enabled for the database instance.
Explanation:
Other Processes
There are several other background processes that might be running. These can include the
following:
The Manageability Monitor process (MMON) performs various manageability-related backgroundtasks, for example:
* Issuing alerts whenever a given metrics violates its threshold value
* Taking snapshots by spawning additional process (MMOX slaves)
* Capturing statistics value for SQL objects that have been recently modified
The Lightweight Manageability Monitor process (MMXL) performs frequent tasks related to
lightweight manageability, such as session history capture and metrics computation.
The Memory Manager process (MMAN) is used for internal database tasks. It manages automatic
memory management processing to help allocate memory where it is needed dynamically in an
effort to avoid out-of-memory conditions or poor buffer cache performance.
