数据库连接问题~救命啦~急~

shining51 2010-12-10 12:23:46

本地XP环境下安装的ORACLE,
本来好好的,这两天出现了PL*SQL无法连接的情况,一连接就死在那里.
SQLPLUG连接却没问题,请问这是为什么啊~
另外,用Net Manager配置的测试连接也会死...

配了N次了,都不行,应该不是监听配置的问题吧.SQL*PLUG连接正常啊

没有错误提示？
是不是中病毒了，用杀软查一下

ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = IP或localhost)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = IP或localhost)(PORT = 1521))
)

上面两个文件保持一致

先确定是不是sqlplus连得时候没用服务名，而PLSQL用了服务名，如果确实这样估计监听有问题，比如防火墙或者是不是域名出问题了。如果都有服务名，可能环境变量有问题，同时装了很多回ORACLE，PLSQL和Net Manager指定到不是当前的ORACLE中去了

把所有的端口开绿色通道试试关闭防火墙以及病毒查杀
