linux下手工创建数据库过程
1.停止数据库
sqlplus /nolog
conn / as sysdba;
shutdown
?
2.创建sid，修改oracle用户环境变量.bash_profile 文件
返回oracle用户根目录
cd 回车
vi .bash_profile
内容如下：
PATH=$PATH:$HOME/bin
ORACLE_BASE=/opt/oracle/10g;?? export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE;?? export ORACLE_HOME
ORACLE_SID=ora10g;?? export ORACLE_SID
PATH=$ORACLE_HOME/bin:$PATH
export PATH
unset USERNAME
保存退出。
使变量生效：
. .bash_profile
?
3.创建目录：
诊断目录
mkdir -p /opt/oracle/admin/ora10g
mkdir -p /opt/oracle/admin/ora10g/adump
mkdir -p /opt/oracle/admin/ora10g/bdump
mkdir -p /opt/oracle/admin/ora10g/cdump
mkdir -p /opt/oracle/admin/ora10g/udump
mkdir -p /opt/oracle/admin/ora10g/pfile
mkdir -p /opt/oracle/admin/ora10g/initsql
数据文件目录：
mkdir -p /opt/oracle/oradata/ora10g
mkdir -p /opt/oracle/oradata/ora10g/archive
?
4.在/opt/oracle/admin/ora10g/pfile目录下创建参数文件：
initora10g.ora,内容如下：
ora10g.__db_cache_size=331350016
ora10g.__java_pool_size=4194304
ora10g.__large_pool_size=8388608
ora10g.__shared_pool_size=138412032
ora10g.__streams_pool_size=0
*._kgl_large_heap_warning_threshold=8388608
*.audit_file_dest='/opt/oracle/admin/ora10g/adump'
*.background_dump_dest='/opt/oracle/admin/ora10g/bdump'
*.compatible='10.2.0.1.0'
*.control_files='/opt/oracle/oradata/ora10g/control01.ctl','/opt/oracle/oradata/ora10g/control02.ctl','/opt/oracle/oradata/ora10g/control03.ctl'
*.core_dump_dest='/opt/oracle/admin/ora10g/cdump'
*.db_2k_cache_size=33554432
*.db_block_size=8192
*.db_domain=''
*.db_file_multiblock_read_count=128
*.db_files=4000
*.db_name='ora10g'
*.db_recovery_file_dest_size=4294967296
*.db_recovery_file_dest=''
*.log_archive_dest='/opt/oracle/oradata/ora10g/archive'
*.log_checkpoints_to_alert=FALSE
*.open_cursors=300
*.parallel_execution_message_size=65535
*.parallel_max_servers=128
*.pga_aggregate_target=209715200
*.processes=150
*.recyclebin='OFF'
*.remote_login_passwordfile='EXCLUSIVE'
*.replication_dependency_tracking=FALSE
*.session_cached_cursors=100
*.sga_target=500m
*.shared_pool_size=100m
*.undo_management='AUTO'
*.undo_retention=0
*.undo_tablespace='UNDOTS'
*.user_dump_dest='/opt/oracle/admin/ora10g/udump'
*.workarea_size_policy='AUTO'
_allow_resetlogs_corruption=true
?
5.创建密码文件
orapwd file=/opt/oracle/10g/dbs/orapwora10g.ora password=admin entries=5 force=y
?
6.在/opt/oracle/admin/ora10g/initsql目录下编写建库脚本createdb.sql,内容如下：
CREATE DATABASE ora10g
LOGFILE
GROUP 1 ('/opt/oracle/oradata/ora10g/redo01.log','/opt/oracle/oradata/ora10g/redo01_1.log') size 100m reuse,
GROUP 2 ('/opt/oracle/oradata/ora10g/redo02.log','/opt/oracle/oradata/ora10g/redo02_1.log') size 100m reuse,
GROUP 3 ('/opt/oracle/oradata/ora10g/redo03.log','/opt/oracle/oradata/ora10g/redo03_1.log') size 100m reuse
MAXLOGFILES 50
MAXLOGMEMBERS 5
MAXLOGHISTORY 200
MAXDATAFILES 500
MAXINSTANCES 5
ARCHIVELOG
CHARACTER SET ZHS16GBK
NATIONAL CHARACTER SET AL16UTF16
DATAFILE '/opt/oracle/oradata/ora10g/system01.dbf' SIZE 1000M EXTENT MANAGEMENT LOCAL
SYSAUX DATAFILE '/opt/oracle/oradata/ora10g/sysaux01.dbf' SIZE 1000M
UNDO TABLESPACE UNDOTS DATAFILE '/opt/oracle/oradata/ora10g/undo.dbf' SIZE 500M
DEFAULT TEMPORARY TABLESPACE TEMP TEMPFILE '/opt/oracle/oradata/ora10g/temp.dbf' SIZE 500M;
?
7.启动数据库，并初始化
sqlplus /nolog
conn / as sysdba;
startup nomount pfile=/opt/oracle/admin/ora10g/pfile/initora10g.ora
数据库启动完毕
8.执行建库脚本
@/opt/oracle/admin/ora10g/initsql/createdb.sql
数据库创建完成
9.数据库创建完成后，再创建ORACLE的数据字典。
SQL>@?/rdbms/admin/catalog.sql
SQL>@?/rdbms/admin/catproc.sql
SQL>@?/rdbms/admin/catexp.sql
到此ORACLE手动创建过程就完成了
?
10.创建表空间
create tablespace portal
datafile '/opt/oracle/oradata/ora10g/portal.dbf'
size 10000M
AutoExtend On Next 100M Maxsize unlimited
extent management local
segment space management auto;
?
11.修改system用户密码为manager
sqlplus /nolog
conn / as sysdba;
alter user system identified by manager;
12.修改网络连接tns内容，进入/opt/oracle/10g/network/admin目录，编辑tnsnames.ora文件
文件内容如下：
ORA10G =
? (DESCRIPTION =
??? (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.4.155)(PORT = 1521))
??? (CONNECT_DATA =
????? (SERVER = DEDICATED)
????? (SERVICE_NAME = ora10g)
??? )
? )
?
EXTPROC_CONNECTION_DATA =
? (DESCRIPTION =
??? (ADDRESS_LIST =
????? (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
??? )
??? (CONNECT_DATA =
????? (SID = PLSExtProc)
????? (PRESENTATION = RO)
??? )
? )
?
修改监听文件listener.ora:
vi listener.ora
内容如下：
# listener.ora Network Configuration File: /opt/oracle/10g/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
? (SID_LIST =
??? (SID_DESC =
????? (SID_NAME = PLSExtProc)
????? (ORACLE_HOME = /opt/oracle/10g)
????? (PROGRAM = extproc)
??? )
? )
(SID_DESC =
? (GLOBAL_DBNAME = ORACLE)
???? (ORACLE_HOME = /opt/oracle/10g)
???? (SID_NAME = ora10g)
)
LISTENER =
? (DESCRIPTION_LIST =
??? (DESCRIPTION =
????? (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
????? (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.4.155)(PORT = 1521))
??? )
? )
?
13.创建用户
//创建用户并指定表空间??
SQL> create user portal identified by portal
default tablespace portal
temporary tablespace temp;
create user WAP20 identified by WAP20
default tablespace portal
temporary tablespace temp;
grant DBA,CONNECT,RESOURCE TO WAP20;
//给用户授予权限
SQL> GRANT CREATE USER,DROP USER,ALTER USER,CREATE ANY VIEW,
DROP ANY VIEW,EXP_FULL_DATABASE,IMP_FULL_DATABASE,
DBA,CONNECT,RESOURCE,CREATE SESSION TO portal;
?
14.启动监听
lsnrctl start
至此，数据库创建完成，用户创建完成，若要导入数据，可通过imp user/password@ora10g full=y file=xxx.dmp log=import.log ignore=y,导入所需的dmp文件
本例中用到的dmp文件导入如下：
imp portal/portal@ora10g full=y file=/opt/aspire/product/expportal.dmp log=expport.log ignore=y
?
查看数据库字符集：
select userenv('language') from dual;
注意dmp文件的字符集需与数据库的字符集保持一致，数据库字符集在创建数据库时指定，具体见建库脚本部分；
