What is Automatic Memory Management (AMM)?

What does AMM stand for?

Automatic Memory Management (AMM) is a way in which an running Device or utility robotically manages the allocation and deallocation of Memory. This way that a Programmer does not must write Code to perForm memory control obligations when growing an application. Automatic reminiscence control can Cast off commonplace problems along with forgetting to loose reminiscence allocated to an item and inflicting a Memory Leak, or attempting to get right of entry to reminiscence for an item that has already been Freed.

Garbage Collection is a shape of automated reminiscence management.

What Does Automatic Memory Management Mean?

Oracle has proprietary AMM Parameters, along with PGA_AGGREGATE_TARGET and SGA_TARGET. Oracle uses two iNitialization parameters to configure AMM, as follows:

• MEMORY_TARGET: Set at 0 with the aid of default. Dynamically facilitates the adjustment of Oracle’s overall reminiscence Availability as much as MEMORY_MAX_TARGET boundaries.
• MEMORY_MAX_TARGET: Defines the maximum length of MEMORY_TARGET, which may be increased with out restarting an example.

The .NET commonplace language Run Time’s rubbish collector manages the allocation and launch of reminiscence for an utility. The following happens during new .NET Framework Procedure initialization:

• AMM reserves the cope with space’s adJoining vicinity at run time, that's referred to as the Managed Heap.
• This cope with space has an deal with pointer, that's used to allocate next items.
• The pointer is to begin with set to control the Heap’s Base Address, in which every Reference Type is also allotted.

Managed heap Memory Allocation is more green than unmanaged memory allocation.
