【Oracle】环境变量与监听文件

一、环境变量的及其含义:

   　　数据库主目录　　　ORACLE_HOME=D:\app\Administrator\product\11.2.0\dbhome_1

   监听文件所在目录  　 TNS_ADMIN=D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN
　　　　　　　或者　　　 TNS_ADMIN=D:\Program Files\PLSQL\ 

简体中文的编码格式 　　 NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK -- 中文字符集
　　　　　　　或者　　　 NLS_LANG=SIMPLIFIED CHINESE_CHINA.AL32UTF8 --美式UTF8字符集
　　　　JDK主目录     JAVA_HOME=D:\Program Files\Java\jdk1.7.0_79

        JDK类路径      CLASSPATH=.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;

 可执行文件所在路径 　　 Path=%JAVA_HOME%\bin;D:\app\Administrator\product\11.2.0\dbhome_1\bin

二、监听文件

listener.ora

# listener.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )
ADR_BASE_LISTENER = D:\app\Administrator

tnsnames.ora

# Generated by Oracle configuration tools.

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )
# 本地主机
ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

ZHENG =
(DESCRIPTION =
　　(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.11.219)(PORT = 1521))
　　(CONNECT_DATA =
　　　　(SERVER = DEDICATED)
　　　　(SERVICE_NAME = zheng.bonc.com) # 此处为全局数据库名 也可以为某个存在的数据库名
　　)
