using the easy connect naming method 简单连接測试

  一直都不明确sqlnet.ora中的NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)是什么意思。今天看到一篇文档，就是登陆选用的方式。做一个測试：
tnsnames.ora 
10.10.32.119 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.32.119)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl11g)
    )
  )
  
sqlnet.ora  
NAMES.DIRECTORY_PATH= (TNSNAMES)
