• Oracle ASM启动


    1,安装好ASM后,启动ASM数据的过程
    启动ASM 数据库的步骤
    由于启动ASM 数据库必须要先启动ASM 实例,所以基本上启动步骤如下。
    1. 以oracle 用户进入操作系统
    2. $ export ORACLE_SID=+ASM  //ORACLE_SID一定要大写。
    3. $ sqlplus / as sysdba
    4. SQL> startup
    5. SQL> exit
    6. $ export ORACLE_SID=<your_real_db_sid>
    7. $sqlplus / as sysdba
    8. SQL> startup

    需要启动2个oracle_sid

    2,启动监听器:  lsnrctl start

    监听器  listener.ora实例

    # listener.ora Network Configuration File: /opt/app/oracle/product/10.2.0.1/db_1/network/admin/listener.ora
    # Generated by Oracle configuration tools.
    SID_LIST_LISTENER =
    (SID_LIST =
    (SID_DESC =
    (SID_NAME = +ASM)
    (ORACLE_HOME = /opt/app/oracle/product/10.2.0.1/db_1)
    (GLOBAL_DBNAME=+ASM )
    )
    (SID_DESC =
    (SID_NAME = czdev)
    (ORACLE_HOME = /opt/app/oracle/product/10.2.0.1/db_1)
    (GLOBAL_DBNAME=czdev )
    )


    (SID_DESC =
    (SID_NAME = PLSExtProc)
    (ORACLE_HOME = /opt/app/oracle/product/10.2.0.1/db_1)
    (PROGRAM = extproc)
    )
    )

    LISTENER =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = Rm-DevDB)(PORT = 1521))
    )
    )
    3,启动web 管理页面
       $emctl start dbconsole

    远程连接ASM数据配置listener.ora的情况

    listener.ora 这个文件的配置
    服务器端的配置
    [oracle@rs2600-2 admin]$ vi listener.ora

    # listener.ora Network Configuration File: /opt/app/oracle/product/10.2.0/server/network/admin/listener.ora
    # Generated by Oracle configuration tools.

    LSNRASM =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = rs2600-2)(PORT = 1521))
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
    )

    SID_LIST_LISTENER =
    (SID_LIST =
    (SID_DESC =
    (GLOBAL_DBNAME = +ASM)
    (ORACLE_HOME = /opt/app/oracle/product/10.2.0/server)
    (SID_NAME = +ASM)
    )
    (SID_DESC =
    (GLOBAL_DBNAME = danghj)
    (ORACLE_HOME = /opt/app/oracle/product/10.2.0/server)
    (SID_NAME = danghj)
    )
    (SID_DESC =
    (SID_NAME = PLSExtProc)
    (ORACLE_HOME = /opt/app/oracle/product/10.2.0/server)
    (PROGRAM = extproc)
    )
    )

    LISTENER =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = rs2600-2)(PORT = 1521))
    )
    )

    客户端的配置
    ASM_172.22.11.124 =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.22.11.124)(PORT = 1521))
    )
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = danghj)
    )
    )

    4.启动Emctl
    # emctl start dbconsole
    # emctl status dbconsole //查看状态

    4,Oracle 中删除 ASM 实例

      删除自动存储管理实例+ASM实例+ASM的删除是在数据库被卸载之后完成的,并删除/ORACLE_HOME/dbs目录下的所有文件(除了 与ASM相关的)。因此必须完成下列步骤:

      4.1在命令提示符中,设置oracle_sid环境变量为+ASM实例:

      # export oracle_sid=+ASM

      4.2启动SQL*Plus并以sys用户连接到自动存储管理+ASM实例:

      # sqlplus / as sysdba

      4.3使用下列命令来确定是否有数据库实例正在使用自动存储管理实例+ASM:

      SQL>select instance_name from v$asm_client;

      该命令结果列出所有正在运行并使用+ASM实例的数据库实例。只要+ASM包含正在支持的数据库实例,就不能删除该+ASM实例。(其实可以先 shutdown对应的数据库实例,然后从asmcmd进入磁盘组所在目录,删掉对应的数据库目录和文件就可以了)。

      4.4 如果没有与+ASM相关联的数据库实例,则删除与该实例相关联的磁盘组。

      首先,识别与+ASM相关联的磁盘组:

      SQL>select name from v$asm_diskgroup;

      其次,用下列命令删除每个要删除的磁盘组:

      SQL>drop diskgroup<disk_group_name>including contents;

      4.5 关闭+ASM实例并退出SQL*Plus:

      SQL>shutdown

      SQL>exit

      4.6 在命令提示符中输入下列命令,删除+ASM服务(我没找到这个命令,所以没有运行):

      oradim -delete -asmsid +ASM

    4,到ASM磁盘输入sys密码连接不上,显示网络问题

    需要启动istener就可以了
