Oracle 10.2.0.4 , Linux AS 5.3 64bit .

Listener.ora 檔案如下，配置應該沒有錯誤：

LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 10.13.13.188)(PORT = 1526))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
    )
)

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/product/oracle)
      (PROGRAM = extproc)
    )
   (SID_DESC =
      (GLOBAL_DBNAME = b2b)
      (ORACLE_HOME = /u01/product/oracle)
      (SID_NAME = b2b)
    )
)

開啟監聽的時候報錯：

MXB2B-WEB01$lsnrctl start

後來發現 /etc/hosts 中的 127.0.0.1 對應的不是localhost 而是實際的主機名稱，如下：

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 MXB2B-WEB01
10.13.13.188 MXB2B-WEB01

修改/etc/hosts 為下面的形式：

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
10.13.13.188 MXB2B-WEB01

再次開啟監聽， OK .

MXB2B-WEB01$lsnrctl start
