The shared pool in the SGA consists of a library cache, a dictionary cache (Dictionary cache), a buffer for parallel execution messages, and a control structure. The size of the Shared POOL is determined by the parameter shared_pool_size. 9i, the default value of this parameter is 8M under 32-bit system, and the default value of 64-bit system is 64M. The maximum is 4G. 10g can be adjusted automatically by Sga_target parameters. Memory management for shared pool is achieved through a modified L

The advantages of this method: 1, the integration of Oracle client within the program, no need to configure users themselvesThe disadvantage of this method: 2, increase the volume of the package (Oracle Instant client itself has a few 10 megabytes size)Here's how it's implemented. 0.
