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

   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;
