記錄一下navicat連接Oracle數據庫過程：

　　一、根據自己版本去Oracle官網下載instantclient

　　地址：https://www.oracle.com/technetwork/topics/winx64soft-089540.html

　　二、 navicat設置OCI環境

　　進入navicat --> 工具 --> 選項 --> 環境添加instantclient oci.dll 重啟後生效

　　三、Oracle數據庫連接配置

　　知道Oracle數據庫的TNS，如下：

fhzc_produce_boss=
    (DESCRIPTION 
 
=
        (ADDRESS = (PROTOCOL = TCP)(HOST = 10.20.0.13)(PORT = 1521))
        (ADDRESS = (PROTOCOL = TCP)(HOST = 10.20.0.14)(PORT = 1521))
            (CONNECT_DATA =
                (SERVER = DEDICATED)
                (SERVICE_NAME = rac)
            )
    )

test_db1=
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.20.1.45)(PORT = 1521))
    (CONNECT_DATA 
 
=
      (SERVER = DEDICATED)
      (SERVICE_NAME = testdb1)
    )
  )
