Shared Pool

The shared pool is used to store the most recently executed SQL statements and the most recently used data definitions. The shared pool caches various types of program data. The shared pool stores parsing, interpreting, and executing all of the SQL statements and data dictionary information. The shared pool includes the following components:

• The library cache
• The dictionary cache
• Reserved Pool

The total size of the shared pool is determined by the initialization parameter SHARED_POOL_SIZE. Increasing the value of this parameter increases the amount of memory reserved for the shared pool.
