Oracle-创建服务器参数文件

允许使用传统的init.ora或SPFILE作为配置文件。但是建议所有数据库创建和使用一个SPFILE。可以从init.ora创建SPFILE

SQL> CREATE spfile FROM pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/inityoon.ora';

也可以给出明确的名字来创建SPFILE

SQL>CREATE spfile='/u01/app/oracle/product/11.2.0/db_1/dbs/nina_spfile.ora' FROM pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initnina.ora'

如果希望Oracle利用init.ora文件创建一个SPFILE

SQL>create spfile from pfile;

关闭数据库，实例将使用新的SPFILE启动，将在默认位置按照下面书序查找初始化参数文件，并且将使用找到的第一个初始化参数文件

1 默认位置查找spfile$ORACLE_SID.ora;
2 默认位置查找名为spfile.ora文件
3 默认为诶之查找传统的init.ora文件，起名字为init$ORACLE_SID.ora

如果需要使用init.ora来启动，则可以

SQL>STARTUP PFILE='/u01/app/oracle/product/11.2.0/db_1/dbs/initnina.ora'
