memory region

The processor determines the type of a given memory region mainly by looking at page tables, which are maintained by the kernel.

When contiguous chunks of the same data types are allocated, the memory region is known as a buffer.

The memory region size (also called logical memory block (LMB) size) must be the same on the source and destination systems.

Shared memory allows multiple processes to map a portion of their virtual address to a common memory region.

The provider typically holds these objects in a short-term memory region called persistent context in JPA nomenclature.

Any process can write data to a shared memory region, and the data are readable and modified by other processes.

To notify callers of the address and size of a memory region.

The working storage pages for shared memory regions are not released until the shared memory region is deleted.

Note that each process can map the shared memory region to different addresses in their respective address spaces.

The memory region is a pure-memory cache region that uses a Least Recently Used (LRU) algorithm.

For DB2, the largest consumer of system main memory is its buffer pool, which is basically a single, large shared memory region.

A server creates a shared memory region and sets up a shared lock object

Both the client and server can use the shared lock object to get access to the shared memory region
