Sqlplus /nolog
Conn / as sysdba
Create pfile=’d:bk.ora’ from spfile;
4、 修改ORACLE的spfile值,在数据库打开时,在sqlplus下执行以下命令:
Alter system set use_indirect_data_buffers=true scope=spfile;
Alter system set pre_page_sga=true scope=spfile;
Alter system set db_block_buffers=262144 scope=spfile;
(修改完成后,SGA的大小为db_block_size* db_block_buffers=8k*256K=2G)
