Oracle11gR2--手工建库&dbca建库

1 Oracle11gR2 dbca建库

[oracle@localhost ~]$ cd $ORACLE_BASE/database

[oracle@localhost database]$ dbca -silent -createDatabase -templateName $ORACLE_HOME/assistants/dbca/templates/General_Purpose.dbc -gdbname orcl -sid orcl -characterSet ZHS16GBK

2 Oracle11gR2手工建库

2.1.指定Oracle SID

[oracle@localhost ~]$ echo $ORACLE_SID
orcl

2.2.设置环境变量

[oracle@localhost ~]$ echo $ORACLE_HOME
/home/oracle/app/oracle/product/11.2.0/dbhome_1
[oracle@localhost ~]$ echo $ORACLE_BASE
/home/oracle/app
由于这些参数已经在安装oracle软件的时候写入了环境变量，这里就不再修改

2.3.选择认证方式，创建密码文件

[oracle@localhost ~]$ cd $ORACLE_HOME/dbs
[oracle@localhost dbs]$ orapwd file=/home/oracle/app/oracle/product/11.2.0/dbhome_1/dbs/orapworcl entries=30  

Enter password for SYS:

2.4.创建参数文件

[oracle@localhost ~]$ cd $ORACLE_HOME/dbs
[oracle@localhost dbs]$ cp init.ora initorcl.ora
[oracle@localhost dbs]$ ls
init.ora  initorcl.ora  orapworcl
[oracle@localhost dbs]$ vim initorcl.ora  

# Change '<ORACLE_BASE>' to point to the oracle base (the one you specify at
# install time)  

db_name='ORCL'
memory_target=900m
processes = 150
audit_file_dest='/home/oracle/app/admin/orcl/adump'
audit_trail ='db'
db_block_size=8192
db_domain=''
db_recovery_file_dest='/home/oracle/app/flash_recovery_area'
db_recovery_file_dest_size=2G
diagnostic_dest='/home/oracle/app'
dispatchers='(PROTOCOL=TCP) (SERVICE=ORCLXDB)'
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 = ('/home/oracle/app/oradata/orcl/control01.ctl', '/home/oracle/app/oradata/orcl/control02.ctl')
compatible ='11.2.0'
"initorcl.ora" 66L, 2856C written      

#注：需要根据参数文件中的参数创建相应的目录,创建后重新赋一次权限

[root@localhost ~]# mkdir -p /home/oracle/app/admin/orcl/adump
[root@localhost ~]# mkdir -p /home/oracle/app/flash_recovery_area
[root@localhost oradata]$ mkdir -p /home/oracle/app /oradata/orcl
[root@localhost ~]# chown -R oracle:oinstall /home/oracle/app/
[root@localhost ~]# chmod -R 775 /home/oracle/app/

2.5.连接到数据库,启动到nomount状态

[oracle@localhost ~]$ cd $ORACLE_HOME/dbs
[oracle@localhost dbs]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.4.0 Production on Sat Nov 19 02:09:58 2016

Connected to an idle instance.  

SQL> startup nomount
ORACLE instance started.

2.6. 执行建库脚本

SQL> CREATE DATABASE orcl
  2     USER SYS IDENTIFIED BY oracle
  3     USER SYSTEM IDENTIFIED BY oracle
  4     LOGFILE GROUP 1 ('/home/oracle/app/oradata/orcl/redo01a.log','/home/oracle/app/oradata/orcl/redo01b.log') SIZE 100M BLOCKSIZE 512,
  5             GROUP 2 ('/home/oracle/app/oradata/orcl/redo02a.log','/home/oracle/app/oradata/orcl/redo02b.log') SIZE 100M BLOCKSIZE 512,
  6             GROUP 3 ('/home/oracle/app/oradata/orcl/redo03a.log','/home/oracle/app/oradata/orcl/redo03b.log') SIZE 100M BLOCKSIZE 512

 15     SYSAUX DATAFILE '/home/oracle/app/oradata/orcl/sysaux01.dbf' SIZE 325M REUSE
 16     DEFAULT TABLESPACE users
 17        DATAFILE '/home/oracle/app/oradata/orcl/users01.dbf'
 18        SIZE 500M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED
 19     DEFAULT TEMPORARY TABLESPACE temp

 21        SIZE 20M REUSE
 22     UNDO TABLESPACE UNDOTBS1
 23        DATAFILE '/home/oracle/app/oradata/orcl/undotbs01.dbf'
 24        SIZE 200M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;  

Database created.

2.7. 执行创建数据字典脚本

@?/rdbms/admin/catalog.sql
@?/rdbms/admin/catproc.sql
@?/sqlplus/admin/pupbld.sql #需使用system用户执行
