使用命令创建数据库

1 、确定数据库的sid 和db_name

sid='hsj'

db_name='hsj'

2、设置环境变量env

ORACLE_BASE=/u01/app

ORACLE_HOME=$ORACLE_BASE/oracle

ORACLE_SID=hsj

PATH=$ORACLE_HOEM/bin:$PATH;

LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH

export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH



3、设置登录方法，使用操作系统登录还是远程登录

使用本地操作系统用户，具有dba权限的oracle用户

sqlplus /nolog

conn as sysdba;

4、创建一个使用的pfile文件

vi inithsj.ora

hsj.__db_cache_size=385875968

hsj.__java_pool_size=4194304

hsj.__large_pool_size=4194304

hsj.__shared_pool_size=163577856

hsj.__streams_pool_size=0

audit_file_dest='/u01/app/admin/hsj/adump'

background_dump_dest='/u01/app/admin/hsj/bdump'

compatible='10.2.0.1.0'

control_files='/u01/app/oradata/hsj/control01.ctl','/u01/app/oradata/hsj/control02.ctl','/u01/app/oradata/hsj/control03.ctl'

core_dump_dest='/u01/app/admin/hsj/cdump'

db_block_size=8192

db_domain=''

db_file_multiblock_read_count=16

db_name='hsj'

db_recovery_file_dest='/u01/app/flash_recovery_area'

db_recovery_file_dest_size=2147483648

dispatchers='(PROTOCOL=TCP) (SERVICE=hsjXDB)'

job_queue_processes=10

log_archive_format='%t_%s_%r.dbf'

open_cursors=300

pga_aggregate_target=187695104

processes=150

remote_login_passwordfile='EXCLUSIVE'

sga_target=563085312

undo_management='AUTO'

undo_tablespace='UNDOTBS1'

user_dump_dest='/u01/app/admin/hsj/udump'



5、根据pfile文件创建想对应的目录

需要在$ORACLE_BASE/admin 下创建一个目录 hsj及其相关的子目录

$ORACLE_BASE/oradate 下面增加一个目录 hsj 及其子目录 archivelog

6、根据pfile文件创建spfile

startup nomount;

create spfile from pfile;

shutdown immediate;

7、在$ORACLE_HOME/dbs/ 下创建 orapwhsj

orapwd file=orapwhsj password=root entries=5

8、使用spfile启动数据库到nomount状态

startup up nomount

9、使用脚本创建数据库

spool db.log;

CREATE DATABASE "hsj"

USER SYS IDENTIFIED BY root

USER SYSTEM IDENTIFIED BY root

MAXDATAFILES 500

MAXINSTANCES 8

MAXLOGFILES 32

CHARACTER SET "UTF8"

NATIONAL CHARACTER SET AL16UTF16

ARCHIVELOG

DATAFILE '/u01/app/oradata/hsj/system01.dbf' size 300M

EXTENT MANAGEMENT LOCAL

SYSAUX DATAFILE '/u01/app/oradata/hsj/sysaux01.dbf' SIZE 325M REUSE

DEFAULT TEMPORARY TABLESPACE temp TEMPFILE '/u01/app/oradata/hsj/tempts01.dbf' SIZE 100M

EXTENT MANAGEMENT LOCAL

UNDO TABLESPACE "UNDOTBS1"

DATAFILE '/u01/app/oradata/hsj/undotbs01.dbf' SIZE 200M

LOGFILE

GROUP 1 (

'/u01/app/oradata/hsj/redo01a.rdo',

'/u01/app/oradata/hsj/redo01b.rdo'

) SIZE 100M,

GROUP 2 (

'/u01/app/oradata/hsj/redo02a.rdo',

'/u01/app/oradata/hsj/redo02b.rdo'

) SIZE 100M,

GROUP 3 (

'/u01/app/oradata/hsj/redo03a.rdo',

'/u01/app/oradata/hsj/redo03b.rdo'

) SIZE 100M

;

spool off;

10 运行脚本创建数据字典

@ORACLE_HOME/admin/catalog.sql(@/u01/app/oracle/admin/catalog.sql)

@ORACLE_HOME/admin/catproc.sql(@/u01/app/oracle/admin/catproc.sql)

11 启动数据库

startup

12 备份数据库

backup database
