PLSQL登入不进去,提示无监听程序,??,第1张

一、检查服务状态,监听和DB服务是否启动;

二孝卜禅、如果服务器状态正常,检查Oracle客户端$ORACLE\NETWORK\ADMIN\TNSNAME.ORA是否正确配置;

三、客户弊悔端也配置正常,确认客户端是否安装有多个Oracle产品,按如下步骤解决

你的机器上应该是安装了多个Oracle产品,默认的sqlplus和PL/SQL Developer使用了不同路径下的tnsname。

这个问题有两种解决方法:

1.配置每个Oracle产品的$ORACLE_HOME/NETWORK/ADMIN/TNSNAME.ORA

2.配置PL/SQL Developer使用的tnsname

打开PL/SQL Developer,点击“Cancel”进入“PLS/SQL Developer(Not logged on)”,选择Tools >巧尘>Preferences 打开Preferences窗口,选择 Connection >>Oracle Home下拉框,选择tnsname。

先看是什么系统,windows 的话 看看监听服务有没有启动,linux 或unix shell 下用 lsnrctl start 尝试一下看能不能启动监听 , 上述没用的话 用netca重新配置一下监听
