Oracle的第一次亲密接触的几个瞬间

 之前学姐在公司DBA私服上装过一台Oracle 10G 昨天想起来要装Informatica 索性就想把这个台尘封已久的文物弄醒。

首先第一个问题，怎么run起来!!! SVN上有学姐和其他前辈的文档，其中有一篇就是安装文档，找到如下密码。

10.1 启动服务 

监听器接受客户端得连接请求 并验证创建数据库连接

[oracle@TSM54-Test database]$ lsnrctl status

启动和停止服务 

[oracle@TSM54-Test database]$ lsnrctl start

[oracle@TSM54-Test database]$ lsnrctl stop 

启动和停止OEM 服务

[oracle@TSM54-Test database]$emctl start dbconsole
[oracle@TSM54-Test database]$emctl stop dbconsole

 

10.2 访问web数据库页面

浏览器中输入http://localhost.localdomain:1158/em

10.3 启动和停止数据库

[oracle@TSM54-Test database]$isqlplusctl start

[oracle@TSM54-Test database]$isqlplusctl stop

这就ok了 启动sqlplus Enter user-name:/ as sysdba 接着Startup Ok 显示正常。

第一个事情 先给自己创建一个小号(怪癖，讨厌拿admin root啥的乱窜 木有个性 木有Style)

先创建TableSpaces吧

create temporary tablespace ipquery_temp tempfile '/home/oracle/oradata/ipquery_temp01.dbf' size 64m autoextend on next 64m maxsize 2048m extent management local ;

 

create tablespace ipquery_data logging datafile '/home/oracle/oradata/ipquery_data01.dbf' size 64m autoextend on next 64m maxsize 2048m extent management local;

 

接着创建User 并指派到刚新建的TableSpaces里

create user woody identified by woodyxu default tablespace ipquery_data temporary tablespace ipquery_temp;

 

接着实验该帐号，登陆..被拒接..尼玛 忘加权限了..

grant connect,resource to woody;

grant unlimited tablespace to woody;   -- 授予不限制的表空间 何必呢！

grant select any table to woody;    -- //授予查询任何表

登陆..报错..

ORA-01013: user requested cancel of current operation

貌似是超时了，于是乎。

SQL> startup

ORA-01081: cannot start already-running ORACLE - shut it down first

SQL> shutdown abort;

ORACLE instance shut down.

SQL> startup

ORACLE instance started.

 

然后用Woody这个Account登陆 接着 还是报错

ORA-00257: archiver error. Connect internal only, until freed.

Google了一下原来这台Oracle开启了归档模式，于是乎产生了一坨一坨的ArchiveLog，默认木有定时删除Log的这个步骤(这点和PostgreSQL有一比)

先查一下占用了多少空间

SQL> select * from v$flash_recovery_area_usage;

 

FILE_TYPE    PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES

------------ ------------------ ------------------------- ---------------

CONTROLFILE                   0                         0               0

ONLINELOG                     0                         0               0

ARCHIVELOG                 98.06                         0               2

BACKUPPIECE                   0                         0               0

IMAGECOPY                     0                         0               0

FLASHBACKLOG                  0                         0               0

好吧..进RMAN删

[oracle@mysql-test ~]$ RMAN target sys/******

crosscheck archivelog all;

delete expired archivelog all; // Do you really want to delete the above objects (enter YES or NO)? yes

 

// 或者只保留7天内的Log 其余全删

RMAN> DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-7';

released channel: ORA_DISK_1

allocated channel: ORA_DISK_1

channel ORA_DISK_1: sid=151 devtype=DISK

specification does not match any archive log in the recovery catalog

 

RMAN> list archivelog all;

 

 

List of Archived Log Copies

Key     Thrd Seq     S Low Time  Name

------- ---- ------- - --------- ----

51      1    171     A 05-JUN-11 /usr/local/oracle/flash_recovery_area/ORCL/archivelog/2012_05_09/o1_mf_1_171_7tnjdsdr_.arc

52      1    172     A 05-JUN-11 /usr/local/oracle/flash_recovery_area/ORCL/archivelog/2012_05_09/o1_mf_1_172_7tnjdvbc_.arc

 

RMAN> list expired archivelog all;

 

specification does not match any archive log in the recovery catalog

 

RMAN> exit

 

Sysdba进去再Show一下空间剩余，OK了，重启服务，用小号登陆，一切正常。
