首先需要安裝oracle軟件。

[oracle@ora01 admin]$ uname -a

Linux ora01 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686 i686 i386 GNU/Linux

1.設置環(huán)境變量：

[oracle@ora01 admin]export ORACLE_SID=mydb

[oracle@ora01 admin]export ORACLE_BASE=/u02

[oracle@ora01 admin]export ORACLE_HOME=/u02/oracle

2.創(chuàng)建oracle相關目錄：

1)創(chuàng)建dump目錄：

[oracle@ora01 admin]mkdir -p $ORACLE_BASE/admin/mydb/adump

[oracle@ora01 admin]mkdir -p $ORACLE_BASE/admin/mydb/bdump

[oracle@ora01 admin]mkdir -p $ORACLE_BASE/admin/mydb/cdump

[oracle@ora01 admin]mkdir -p $ORACLE_BASE/admin/mydb/udump

[oracle@ora01 admin]mkdir -p $ORACLE_BASE/admin/mydb/pfile[@more@]

2)創(chuàng)建oracle文件目錄：

[oracle@ora01 admin]mkdir -p $ORACLE_BASE/oradata/mydb

3.創(chuàng)建密碼文件：

[oracle@ora01 admin]orapwd file=$ORACLE_HOME/dbs/orpwdmydb.ora password=manager

4.創(chuàng)建oracle參數(shù)文件：

[oracle@ora01 admin]mkdir -p $ORACLE_HOME/dbs

[oracle@ora01 admin]echo "aq_tm_processes=0

audit_file_dest=/u02/admin/mydb/adump

background_dump_dest=/u02/admin/mydb/bdump

compatible=10.2.0.1.0

control_files=/u02/oradata/mydb/control01.ctl, /u02/oradata/mydb/control02.ctl, /u02/oradata/mydb/control03.ctl

core_dump_dest=/u02/admin/mydb/cdump

db_block_size=8192

db_domain=""

db_file_multiblock_read_count=16

db_name=mydb

instance_name=mydb

dispatchers="(PROTOCOL=TCP) (SERVICE=mydbXDB)"

job_queue_processes=10

nls_length_semantics=BYTE

open_cursors=300

pga_aggregate_target=94371840

processes=150

remote_login_passwordfile=EXCLUSIVE

resource_manager_plan=""

sessions=170

sga_target=285212672

undo_management=AUTO

undo_retention=900

undo_tablespace=UNDOTBS1

user_dump_dest=/u02/admin/mydb/udump" >$ORACLE_HOME/dbs/initmydb.ora

4.創(chuàng)建createdb.sql腳本，用來創(chuàng)建數(shù)據(jù)庫：

[oracle@ora01 admin]echo "create database mydb

LOGFILE

GROUP 1 ('/u02/oradata/mydb/redo01.log') size 10m reuse,

GROUP 2 ('/u02/oradata/mydb/redo02.log') size 10m reuse,

GROUP 3 ('/u02/oradata/mydb/redo03.log') size 10m reuse

MAXLOGFILES 50

MAXLOGMEMBERS 5

MAXLOGHISTORY 200

MAXDATAFILES 500

MAXINSTANCES 5

ARCHIVELOG

CHARACTER SET ZHS16GBK

NATIONAL CHARACTER SET UTF8

DATAFILE '/u02/oradata/mydb/system01.dbf' SIZE 100M reuse autoextend on next 10m maxsize unlimited extent management local

SYSAUX DATAFILE '/u02/oradata/mydb/sysaux01.dbf' SIZE 100M reuse autoextend on next 10m maxsize unlimited

UNDO TABLESPACE UNDOTBS1 DATAFILE '/u02/oradata/mydb/undo.dbf' SIZE 50M reuse autoextend on next 5M maxsize unlimited

DEFAULT TEMPORARY TABLESPACE TEMP TEMPFILE '/u02/oradata/mydb/temp.dbf' SIZE 50M reuse autoextend on next 5M maxsize unlimited;

" >createdb.sql

5.進入sqlplus，創(chuàng)建數(shù)據(jù)庫,創(chuàng)建數(shù)據(jù)字典：

SQL> startup nomount pfile=initmydb.ora

ORACLE instance started.

Total System Global Area 285212672 bytes

Fixed Size 1218992 bytes

Variable Size 92276304 bytes

Database Buffers 188743680 bytes

Redo Buffers 2973696 bytes

SQL> @createdb.sql

Database created.

SQL>@$ORACLE_HOME/rdbms/admin/catalog.sql;

SQL>@$ORACLE_HOME/rdbms/admin/catproc.sql;

6.創(chuàng)建users表空間，并且將其設置為默認表空間：

SQL>create tablespace users logging datafile '$ORACLE_BASE/oradata/mydb/users.dbf' size 5M autoextend on next 1280k maxsize unlimited extent management local segment space management auto;

SQL>alter database default tablespace users;
