Oracle 10G手工创建数据库（Helloblock写作）
Oracle 10G手工创建数据库（Helloblock写作）
1、设置实例名：
修改/home/oracle/.bash_profile文件，添加下列这行内容。
export ORACLE_SID=orcl
修改之后使用命令source /home/oracle/.bash_profile让它生效。
2、创建相关目录：
mkdir /u01/app/oracle/oradata/orcl
mkdir /u01/app/oracle/admin/orcl
mkdir /u01/app/oracle/admin/orcl/adump
mkdir /u01/app/oracle/admin/orcl/bdump
mkdir /u01/app/oracle/admin/orcl/cdump
mkdir /u01/app/oracle/admin/orcl/udump
3、创建密码文件：
cd /u01/app/oracle/product/10.2.0/db_1/dbs
orapwd file=orapworcl password=oracle entries=10 force=y
4、创建参数文件：
cd /u01/app/oracle/product/10.2.0/db_1/dbs
cat init.ora|grep -v ^#|grep -v ^$>initorcl.ora
修改initorcl.ora文件，内容如下：
db_name=orcl
db_block_size=8192
undo_management=auto
undo_tablespace=undotbs
sga_target=500m
control_files=('/u01/app/oracle/oradata/orcl/control01.ctl','/u01/app/oracle/oradata/orcl/control02.ctl')
audit_file_dest='/u01/app/oracle/admin/orcl/adump'
background_dump_dest='/u01/app/oracle/admin/orcl/bdump'
core_dump_dest='/u01/app/oracle/admin/orcl/cdump'
user_dump_dest='/u01/app/oracle/admin/orcl/udump'
5、生成spfile文件，并启动到nomount状态：
sqlplus / as sysdba
create spfile from pfile;
startup nomount;
6、创建数据库：
CREATE DATABASE orcl
USER SYS IDENTIFIED BY oracle
USER SYSTEM IDENTIFIED BY oracle
LOGFILE GROUP 1 ('/u01/app/oracle/oradata/orcl/redo01a.log','/u01/app/oracle/oradata/orcl/redo01b.log') SIZE 300M,
GROUP 2 ('/u01/app/oracle/oradata/orcl/redo02a.log','/u01/app/oracle/oradata/orcl/redo02b.log') SIZE 300M,
GROUP 3 ('/u01/app/oracle/oradata/orcl/redo03a.log','/u01/app/oracle/oradata/orcl/redo03b.log') SIZE 300M
MAXLOGFILES 20
MAXLOGMEMBERS 5
MAXLOGHISTORY 1
MAXDATAFILES 500
MAXINSTANCES 5
CHARACTER SET AL32UTF8
NATIONAL CHARACTER SET AL16UTF16
DATAFILE '/u01/app/oracle/oradata/orcl/system01.dbf'
SIZE 500M REUSE AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL
SYSAUX DATAFILE '/u01/app/oracle/oradata/orcl/sysaux01.dbf'
SIZE 500M REUSE AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED
DEFAULT TABLESPACE users
DATAFILE '/u01/app/oracle/oradata/orcl/users01.dbf'
SIZE 500M REUSE AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED
DEFAULT TEMPORARY TABLESPACE temp
TEMPFILE '/u01/app/oracle/oradata/orcl/temp01.dbf'
SIZE 300M REUSE AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED
UNDO TABLESPACE undotbs
DATAFILE '/u01/app/oracle/oradata/orcl/undotbs01.dbf'
SIZE 200M REUSE AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED;
7、执行脚本：
sqlplus / as sysdba
@?/rdbms/admin/catalog;
@?/rdbms/admin/catproc;
@?/rdbms/admin/catblock;
@?/rdbms/admin/catoctk;
@?/rdbms/admin/owminst.plb;
sqlplus system
@?/sqlplus/admin/pupbld.sql;
8、设置默认表空间和默认临时表空间：
alter database default tablespace users;
alter database default temporary tablespace temp;
