1，啟動ASM 數據庫的步驟
由于啟動ASM 數據庫必須要先啟動ASM 實例，所以基本上啟動步驟如下。
1． 以oracle 用戶進入操作系統
2． $ export ORACLE_SID=+ASM
3,
[oracle@Rm-DevDB ~]$ sqlplus

SQL*Plus: Release 10.2.0.1.0 - Production on Sun May 16 16:55:02 2010

需要重新啟動2遍
8.啟動監聽器：[oracle@Rm-DevDB ~]$ lsnrctl start

9,啟動em控制器：[oracle@Rm-DevDB ~]$ emctl start dbconsole


2，配置listener.ora

正常的監聽器為
[oracle@Rm-DevDB admin]$ lsnrctl status

listener.ora 這個文件的配置

監聽器的操作命令
$ORACLE_HOME/bin/lsnrctl start,其他諸如stop,status等。具體敲完一個lsnrctl后看幫助。
服務器端配置
[oracle@rs2600-2 admin]$ 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 =

)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =

)

LISTENER =

客戶端的配置
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)
)
)

3，tnsnames.ora和tnsnames.ora的作用
當你輸入sqlplus sys/oracle@orcl的時候
1． 查詢sqlnet.ora看看名稱的解析方式，發現是TNSNAME
2． 則查詢tnsnames.ora文件，從里邊找orcl的記錄，并且找到主機名，端口和service_name
3． 如果listener進程沒有問題的話，建立與listener進程的連接。
4． 根據不同的服務器模式如專用服務器模式或者共享服務器模式，listener采取接下去的動作。默認是專用服務器模式，沒有問題的話客戶端就連接上了數據 庫的server process。
5． 這時候網絡連接已經建立，listener進程的歷史使命也就完成了。
