数据库启动时报错

ORA-00381 cannot use both new and old parameters for buffer cache size specification

查oracle官方文档

Cause: User specified one or more of {DB_CACHE_SIZE, DB_RECYCLE_CACHE_SIZE, DB_KEEP_CACHE_SIZE, DB_nK_CACHE_SIZE (where n is one of {2, 4, 8, 16, 32}) AND one or more of {DB_BLOCK_BUFFERS, BUFFER_POOL_KEEP, BUFFER_POOL_RECYCLE}. This is illegal.

Action: Use EITHER the old (pre-Oracle 9.0.0) parameters OR the new ones. Don't specify both. If old size parameters are specified in the parameter file, you may want to replace them with new parameters since the new parameters can be modified dynamically and allow you to configure additional caches for additional block sizes.

打开initBWP.ora文件发现，参数文件中同时存在*.db_cache_size=5452595200和*.db_block_buffers=0两个参数，而这个参数在oracle 9i中是不允许同时存在的。删除*.db_block_buffers=0这一行后重新启动数据库正常，
