Create/Drop Database

Create a Database：

建立 createDB.sql：

• 修改 SYS 密碼
• 修改檔案路徑
• 修改 redolog size

CREATE DATABASE win
   USER SYS IDENTIFIED BY mypass
   USER SYSTEM IDENTIFIED BY mypass
   LOGFILE GROUP 1 ('/opt/oracle/oradata/win/redo01.log') SIZE 100M,
           GROUP 2 ('/opt/oracle/oradata/win/redo02.log') SIZE 100M,
           GROUP 3 ('/opt/oracle/oradata/win/redo03.log') SIZE 100M
   MAXLOGFILES 5
   MAXLOGMEMBERS 5
   MAXLOGHISTORY 1
   MAXDATAFILES 100
   MAXINSTANCES 1
   CHARACTER SET AL32UTF8
   NATIONAL CHARACTER SET AL16UTF16
   DATAFILE '/opt/oracle/oradata/win/system01.dbf' SIZE 1000M REUSE
   EXTENT MANAGEMENT LOCAL
   SYSAUX DATAFILE '/opt/oracle/oradata/win/sysaux01.dbf' SIZE 325M REUSE
   DEFAULT TEMPORARY TABLESPACE temp
      TEMPFILE '/opt/oracle/oradata/win/temp01.dbf' 
      SIZE 500M REUSE AUTOEXTEND ON MAXSIZE 2048M
   UNDO TABLESPACE undotbs1 
      DATAFILE '/opt/oracle/oradata/win/undotbs01.dbf'
      SIZE 200M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;

開始建立

確認環境變數
$ echo $ORACLE_SID
win
$ echo $ORACLE_HOME
/opt/oracle/product/10.2.0/db_1

$ sqlplus /nolog

SQL> connect / as sysdba
SQL> startup nomount
SQL> @createDB.sql

DB 建立完後，還需要執行幾個 SQL

SQL> @?/rdbms/admin/catalog.sql
SQL> @?/rdbms/admin/catproc.sql

SQL> conn system/pass
SQL> @?/sqlplus/admin/pupbld.sql  

PUPBLD.SQL       Create user profiles，必須用 SYSTEM 執行，執行過程中會出現一些錯誤是正常的；如果沒有執行，一般用戶會無法連線 DB。

更多其他的 SQL 可參閱 http://docs.oracle.com/cd/B14117_01/...s.htm#REFRN005

 

Drop a Database：

$ export ORACLE_SID=<my_SID>
$ sqlplus / as sysdba

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

SQL> startup mount exclusive restrict
ORACLE instance started.
