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)
