設定檔 listener.ora

安裝預設：

# listener.ora Network Configuration File: /opt/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /opt/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = ora10g.localdomain)(PORT = 1521))
    )
  )

修改後：

1. 將 SID_LIST_LISTENER 刪除，這用於 Static Service Registration，一般來說少用。
2. 將 EXTPROC1 刪除

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = ora10g.localdomain)(PORT = 1521))
    )
