本文介绍了在数据库配置中，DB_CACHE_SIZE初始化参数替代了早期版本中的DB_BLOCK_BUFFERS参数。DB_CACHE_SIZE用于指定标准块大小缓冲区缓存的大小，单位为字节。为了设置合适的DB_CACHE_SIZE值，用户需要确定所需的缓冲区数量，并将其乘以DB_BLOCK_SIZE中指定的块大小。

The DB_CACHE_SIZE initialization
parameter has replaced the DB_BLOCK_BUFFERS initialization parameter, which was
used in earlier releases. The DB_CACHE_SIZE parameter specifies the size in bytes of
the cache of standard block size buffers. Thus, to specify a value for DB_CACHE_SIZE,
you would determine the number of buffers that you need and multiple that value
times the block size specified in DB_BLOCK_SIZE.

For backward compatibility, the DB_BLOCK_BUFFERS parameter still functions, but it
remains a static parameter and cannot be combined with any of the dynamic sizing
parameters.
