Shared Pool ComponentsDuring the parse stage, the server process uses the area in the SGA known as theshared pool to compile the SQL statement. The shared pool has two primarycomponents: Library cache Data dictionary cacheLibrary Cache The library cache stores information about the most recently usedSQL statements in a memory structure called a shared SQL area. The shared SQL areacontains: The text of the SQL statement The parse tree: A compiled version of the statement The execution plan: The steps to be taken when executing the statementThe optimizer is the function in the Oracle server that determines the optimalexecution plan.Shared Pool Components (continued)Library Cache (continued) If a SQL statement is reexecuted and a shared SQLarea already contains the execution plan for the statement, the server process does notneed to parse the statement. The library cache improves the performance ofapplications that reuse SQL statements by reducing parse time and memoryrequirements. If the SQL statement is not reused, it is eventually aged out of thelibrary cache.Data Dictionary CacheThe data dictionary cache, also known as the dictionary cache or row cache, is acollection of the most recently used definitions in the database. It includes informationabout database files, tables, indexes, columns, users, privileges, and other databaseobjects.During the parse phase, the server process looks for the information in the dictionarycache to resolve the object names specified in the SQL statement and to validate theaccess privileges. If necessary, the server process initiates the loading of thisinformation from the data files.Sizing the Shared PoolThe size of the shared pool is specified by the initialization parameterSHARED_POOL_SIZE.
