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 background tasks, 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.
