oracle 手工建库（笔记）

手工创建数据库(prod):
1.修改环境变量export ORACLE_SID=prod
2.创建口令文件orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=oracle
3.创建参数文件vi $ORACLE_HOME/dbs/initprod.ora-------------------------------------------------------------db_name='prod'compatible=11.2.0.4.0sga_target=600mcontrol_files='/u01/app/oracle/oradata/prod/control01.ctl'audit_file_dest='/u01/app/oracle/admin/prod/adump'diagnostic_dest='/u01/app/oracle'db_recovery_file_dest_size=4gdb_recovery_file_dest='/u01/app/oracle/fast_recovery_area'undo_tablespace=undo01-------------------------------------------------------------
4.创建相关目录mkdir -p /u01/app/oracle/oradata/prodmkdir -p /u01/app/oracle/admin/prod/adumpmkdir -p /u01/app/oracle/fast_recovery_area
5.启动实例到nomountsqlplus / as sysdbacreate spfile from pfile;startup nomountshow parameter name 6.创建数据库create database proddatafile '/u01/app/oracle/oradata/prod/system01.dbf' size 200m autoextend on next 10m extent management localsysaux datafile '/u01/app/oracle/oradata/prod/sysaux01.dbf' size 100m autoextend on next 10mdefault temporary tablespace temp tempfile '/u01/app/oracle/oradata/prod/temp01.dbf' size 50mundo tablespace undo01 datafile '/u01/app/oracle/oradata/prod/undo01.dbf' size 100mcharacter set zhs16gbk national character set al16utf16logfilegroup 1 '/u01/app/oracle/oradata/prod/redo01.log' size 50m,group 2 '/u01/app/oracle/oradata/prod/redo02.log' size 50m; 7.创建数据字典构造PL/SQL运行环境@?/rdbms/admin/catalog@?/rdbms/admin/catproc 8.创建scott用户：conn system/manage@?/sqlplus/admin/pupbld.sql@?/rdbms/admin/utlsampl 
限制用户操作（system用户）insert into product_user_profile (product,userid,attribute,char_value)values ('SQL*Plus','SCOTT','DROP','DISABLED');commit;
9.安装sqlplus help:conn system/managerSYSTEM> @?/sqlplus/admin/help/helpbld.sql如果出现交互模式提示需要输入值：value 1: /u01/app/oracle/product/11.2.0/db_1/sqlplus/admin/help/value 2: /u01/app/oracle/product/11.2.0/db_1/sqlplus/admin/help/helpus.sql 

多个实例如何相互切换export ORACLE_SID=????，实例通过key值作为依据，连接对应的数据库。key为ORACLE_HOME和ORACLE_SID的hash值 ###########################################################################本文适合有点oracle数据库体系架构基础的查看。欢迎扩散，请注明原地址：http://mp.blog.csdn.net/postedit/79350064
