问题如题，试了很多方法当时还是出现这个错误。
sqlplus连接是没有任何问题的。
下面是我本地相关配置。
[oracle@localhost admin]$ vi tnsnames.ora
HPSADB=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 16.156.214.144)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = HPSADB)
)
)
LISTENER_HPSADB=
(ADDRESS = (PROTOCOL = TCP)(HOST = 16.156.214.144)(PORT = 1521))
HPSA_DB=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 16.156.214.144)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = HPSA_DB)
)
)
[oracle@localhost admin]$ vi listener.ora

ADR_BASE_LISTENER = /home/oracle/app

windows上tnsnames.ora配置
HPSA_DB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 16.156.214.144)(PORT = 1521))
)
(CONNECT_DATA =

使用tnsping去ping也是通的
