Oracle Block and its addressing

Question

Illustrates the Oracle Block? How can two Oracle Blocks have the same address?

Answer 1

Oracle "formats" the database files within a number of Oracle blocks while they are initial created—making this easier for the RDBMS software to manage the files and simple to read data within the memory areas.

The block size must be a multiple of the operating system block size. Regardless of the block size, the whole block is not obtainable for holding data; Oracle takes up several spaces to manage the contents of the block. Such block header has a minimum size there, but this can grow.

Such Oracle blocks are the smallest unit of storage. Rising the Oracle block size can develop performance, but this must be done only while the database is first created.

Every Oracle block is numbered sequentially for all database files starting at one. Two blocks can have similar block address when they are in various type database files.
