请问能Windows下连接虚拟机上的oracle数据库吗？

我虚拟机和主机之间都可以ping通
但是tnsping和telnet都不成功

linux中telnet默认是不开的
你虚拟机中什么系统啊？

如果可以ping通，没有防火墙的话
数据库端要配监听
配置正确的tns，应该是可以通的

如果不行，就重新用netca或netmgr重新配一下你的listener.ora文件。

关于tnsnames.ora文件中，别名orcl中，主机你写的是全主机域名，你试一下，能解析吗，如果不能应该改成IP地址。

修改之后，listener.ora和tnsnames.ora的配置如下：（但还是包操作超时）

linux-ayfk:/home/app/oracle/product/11.1.0/db_1/network/admin # more listener.ora
# listener.ora Network Configuration File: /home/app/oracle/product/11.1.0/db_1/

      (SERVICE_NAME = orcl)
    )
  )

重启过listener了吗？他的状态如何？

oraclewlm

关了之后重启，

没有service就不对。你的listener里没有关于数据库信息的描述，如下：
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = test1.bull.com)
      (SID_NAME = test1)
      (ORACLE_HOME = /ora10g/oracle/product/10.2.0)
    )
  )

这个描述了他会为哪些数据库监听。。。。。。。

oraclewlm

监听器这样子有问题吗？
