< p >Oracle11创建实例是数据库管理的一项重要任务,可以将一些无序的数据整理成为一个有序的结构。在这里,我们将从创建Oracle11实例的步骤开始讲解,并提供一些实例创作的技巧。< /p >< p >第一步,需要安装Oracle11g并配置环境变量,然后登录到SQL*Plus中,创建控制文件。具体实现如下:< /p >< pre >CREATE CONTROLFILE REUSE DATABASE "TEST" NORESETLOGS NOARCHIVELOG FORCE LOGGING MAXLOGFILES 16 MAXLOGMEMBERS 3 MAXDATAFILES 100 MAXINSTANCES 8 MAXLOGHISTORY 292 LOGFILE GROUP 1 '/oracle/disk1/oracle11g/oradata/test/redo01.log' SIZE 100M, GROUP 2 '/oracle/disk2/oracle11g/oradata/test/redo02.log' SIZE 100M, GROUP 3 '/oracle/disk3/oracle11g/oradata/test/redo03.log' SIZE 100M DATAFILE '/oracle/disk1/oracle11g/oradata/test/system01.dbf', '/oracle/disk2/oracle11g/oradata/test/sysaux01.dbf', '/oracle/disk3/oracle11g/oradata/test/undotbs01.dbf', '/oracle/disk4/oracle11g/oradata/test/users01.dbf' CHARACTER SET ZHS16GBK ;< /pre >< p >在创建完控制文件后,就可以在Oracle11的启动进程中加入新的实例。具体如下:< /p >< pre >STARTUP NOMOUNT; ALTER SYSTEM SET control_files= '/oracle/disk1/oracle11g/oradata/test/control01.ctl', '/oracle/disk2/oracle11g/oradata/test/control02.ctl' SCOPE=SPFILE;< /pre >< p >在创建完控制文件并启动了新实例之后,需要给新实例设置参数。下面是一些必要的参数:< /p >< pre >*.audit_file_dest='/u01/app/oracle/admin/TEST/adump' *.audit_trail='db' *.compatible='11.2.0.0.0' *.control_files='/oracle/disk1/oracle11g/oradata/test/control01.ctl','/oracle/disk2/oracle11g/oradata/test/control02.ctl' *.db_block_size=8192 *.db_create_file_dest='/oracle/disk1/oracle11g/oradata' *.db_domain='' *.db_name='test' *.db_recovery_file_dest='/oracle/disk1/oracle11g/flash_recovery_area' *.db_recovery_file_dest_size=2G *.db_unique_name='test' *.dispatchers='(PROTOCOL=TCP) (SERVICE=testXDB)' *.memory_target=1G *.open_cursors=300 *.processes=150 *.remote_login_passwordfile='EXCLUSIVE' *.undo_tablespace='UNDOTBS1'< /pre >< p >最后,需要给新实例创建用户,并授予相应的权限。具体步骤可以如下:< /p >< pre >CREATE USER ram IDENTIFIED BY password; GRANT CONNECT,RESOURCE,HR TO ram; ALTER USER ram QUOTA 100M ON USERS;< /pre >< p >通过以上步骤,您就可以成功创建一个新实例并赋予相应的权限。希望这些技巧对您有所帮助。< /p >
