Navicat Premium12远程连接oracle数据库

搞我到心态爆炸

现在终于能连上了，mark一下

其实就是oci版本问题

提示各种错误信息，诸如：

navicat is not able to create oci handles

oracle library is not loaded

以上都是oci版本的问题，

可以去官网直接下载oci版本的包，也就是只包含oci的oracle client : https://www.oracle.com/database/technologies/instant-client/downloads.html，

注意oci版本是根据远程连接的oracle数据库版本来选择的，

还有第二种，直接去下载完整的oracle client，这个除了包含oci之外，还有可以直接配置oracle数据库，并可测试连接，下载地址：http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win64soft-094461.html

安装时选择：

安装后打开Net Configuratinog Assistent进行配置

配置本地网络服务名：

网络服务名即数据库名，主机名为ip地址，选择tcp连接，之后可以测试连接。

另外oracle client安装目录下：F:\Oracle\11.2.0\product\11.2.0\client_1\network\admin

admin文件夹下有sqlnet.ora文件，按理应当还有tnsnames.oRA文件，但是我的目录下并没有。

可以搂一眼sample中的tnsnames.oRA文件，

	      )
	      [ (ADDRESS=
		  (PROTOCOL=ipc)
		  (KEY=)
	         )
	      ]
	      ... 		# More addresses
	    [ ) ] 		# Optional depending on whether ADDRESS_LIST  
				# is being used
	    [ (CONNECT_DATA=
		(SID=)
		[ (GLOBAL_NAME=) ]
	      )
	    ]
	    [ (SOURCE_ROUTE=yes) ]
	  )
	  [ (CONNECT_DATA=
	      (SID=)
	      [ (GLOBAL_NAME=) ]
	    )
	  ]
	  ...   # More descriptions 
	[ ) ]	# Optional depending on whether DESCRIPTION_LIST is used or not

可以看到HOST ADDRESS PORT这些，也许tnsnames.oRA是相当于手动去配置oracle地址？有待进一步研究。
