Shared-Memory Header

The shared-memory header contains a description of all other structures in shared memory, including internal tables and the buffer pool.

The shared-memory header also contains pointers to the locations of these structures. When a virtual processor first attaches to shared memory, it reads address information in the shared-memory header for directions to all other structures.

The size of the shared-memory header is about one kilobyte, but the size varies depending on the computer platform. You cannot tune the size of the header.
