解决安装Oracle本地可以访问客户端不能访问
现象：本地需要修改监听为localhost --》win+r--》 sqlplus system/123@xxdb 可以登陆，远程客户端不能登陆；需要将监听修改为IP地址，重启监听；远程可以访问，plsql：192.168.0.111:50000/xxdb,账号:system密码123
解决方案：将tnsnames.ora的HOST改为ip，将listener.ora的HOST改为本机计算机名称。
配置完重启服务OracleServicexxdb
# tnsnames.ora Network Configuration File: d:apporclproduct12.1.0dbhome_1
etworkadmin nsnames.ora

(CONNECT_DATA =

listener.ora 配置完重启监听

配置完成登陆提示 tns连接超时解决方案：
windows servers 2012控制面板--》系统和安全--》Windows防火墙--》高级设置--》左侧 选择 入站规则--》右侧 新建入站规则
规则类型选端口--》TCP 特定端口填1521--》下一步下一步默认，然后填上名称。
