PLSQL Developer 12远程连接数据库（本地未安装）

第一步：下载安装 PLSQL Developer 12

    百度云：链接：https://pan.baidu.com/s/1wWHkIpryqcDb_pdSl4Ksow 密码：zvzz

第二步：下载Oracle客户端 Instant Client

    链接：http://www.oracle.com/technetwork/cn/database/features/instant-client/index-092699-zhs.html

第三步：配置监听器

    解压下载的Oracle客户端-->instantclient目录下新建文件夹\network\admin\

    方法1：将Oracle数据库配置（/app/oracle12c/product/12.2.0/dbhome_1/network/admin）拷贝到该文件夹下

    方法2：手动创建

    listener.ora

    SID_LIST_LISTENER =
     (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\oracle12c\product\12.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\oracle12c\product\12.2.0\dbhome_1\bin\oraclr12.dll")
    )
  )
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = Oracle服务器ip)(PORT = 1521))    
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )

  )

tnsnames.ora

LISTENER_ORCL =

  (ADDRESS = (PROTOCOL = TCP)(HOST = Oracle服务器ip)(PORT = 1521))

ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = ORCL)
      (PRESENTATION = RO)
    )

  )

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = Oracle服务器ip)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)    #Oracle 全局数据库名
    )

  )

sqlnet.ora

SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
#远程无法连接数据库 在数据库服务器sqlnet.ora中加上这段
SQLNET.ALLOWED_LOGON_VERSION=8   

第四步：PLSQL Developer客户端配置（暂不登录）

配置==>首选项==>连接

Oracle主目录：...\instantclient_11_2 (Oracle客户端所在路径）

OCI库：...\instantclient_11_2\oci.dll (Oracle客户端主目录中的oci.dll文件)

应用，确定，然后就能登录远程数据库了！！！
