使用oracle用户登录,或su到oracle用户
1、首先设置要创建的ORACLE的SID
export ORACLE_SID=addb
2、 创建相应目录
mkdir -p $ORACLE_BASE/admin/addb/a,b,c,udump
mkdir -p $ORACLE_BASE/admin/addb/pfile
mkdir -p $ORACLE_BASE/oradata/addb
3、在$ORACLE_HOME/dbs目录下创建初始化文件
命名方法:init实例名.ora 本例中initaddb.ora
cp init.ora initaddb.ora 即可以生成
vi initaddb.ora 进行编辑,将里面的内容对应修改一下,我的修改完如下:
db_name='addb'
memory_target=1G
processes = 150
audit_file_dest='/data/install/oracle/admin/addb/adump'
audit_trail ='db'
db_block_size=8192
db_domain=''
db_recovery_file_dest='/data/install/oracle/flash_recovery_area'
db_recovery_file_dest_size=2G
diagnostic_dest='/data/install/oracle'
dispatchers='(PROTOCOL=TCP) (SERVICE=addbXDB)'
open_cursors=300
remote_login_passwordfile='EXCLUSIVE'
undo_tablespace='UNDOTBS1'
# You may want to ensure that control files are created on separate physical
# devices
control_files = (ora_control3, ora_control4)
compatible ='11.2.0'
注意不要用原来的<ORACLE_BASE
>作为路径,修改为对应的绝对路径,否则会报错
而且注意control_files应该是新的文件,否则会报文件已存在的错误
4、创建密码文件
orapwd file=$ORACLE_HOME/dbs/orapwaddb password=addb123 entries=5 force=y
这里设置的是sys用户,密码是addb123
5、创建oracle的建库脚本 createdb.sql,内容如下,我将其放在了$ORACLE_BASE/oradata/addb下面
create database addb
MAXINSTANCES 1
MAXLOGHISTORY 1
MAXLOGFILES 5
MAXLOGMEMBERS 5
MAXDATAFILES 100
DATAFILE
'/data/install/oracle/oradata/addb/system01.dbf' size 100m reuse autoextend on next 1m maxsize unlimited extent management local
sysaux datafile
'/data/install/oracle/oradata/addb/sysaux01.dbf' size 100m reuse autoextend on next 1m maxsize unlimited
default temporary tablespace TEMP tempfile
'/data/install/oracle/oradata/addb/temp01.dbf' size 20m reuse autoextend on next 640k maxsize unlimited
undo tablespace UNDOTBS1 datafile
'/data/install/oracle/oradata/addb/undo01.dbf' size 20m reuse autoextend on next 5M maxsize unlimited
logfile
GROUP 1 ('/data/install/oracle/oradata/addb/redo1.dbf') size 10m,
GROUP 2 ('/data/install/oracle/oradata/addb/redo2.dbf') size 10m,
GROUP 3 ('/data/install/oracle/oradata/addb/redo3.dbf') size 10m
CHARACTER SET ZHS16GBK
NATIONAL CHARACTER SET AL16UTF16
;
6、执行建库和数据字典脚本
以sysdba进入:
sqlplus / as sysdba
执行下面命令:
startup nomout;
@$ORACLE_BASE/oradata/addb/createdb.sql
@?/rdbms/admin/catalog.sql;
@?/rdbms/admin/catproc.sql;
@?/rdbms/admin/catexp.sql;
7、修改监听配置文件listener.ora
到$ORACLE_HOME/network/admin目录下:vi listener.ora
addb =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 114.55.30.70)(PORT = 1522))
)
)
)
SID_LIST_addb =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = addb)
(ORACLE_HOME = /data/install/oracle/product/11.2.0/db_1)
(SID_NAME = addb)
)
)
8、启停
启停监听
lsnrctl start addb
lsnrctl stop addb
启停实例
export ORACLE_SID=addb
sqlplus / as sysdba
>startup
>shutdown
