大鸟的ORA-12154问题解决!
安装了Oracle 10g database,配置完变量用PL/SQL操作一切OK .当又安装完Oracle 10g client后,问题出现了,用PL/SQL登陆时反复提示:ORA-12154: TNS: could not resolve the connect identifier specified.刚开始检查配置了tnsnames.ora文件的网络服务名也不行,拷贝了一份我本地机器的配置文件,还不行.纳闷了.
又在"Oracle - OraDb10g_home2"下的"配置和移植工具"中的"Net Manager"中查找问题所在.请教高手,也没有找到问题的原因.我郁闷了,
后来意识到"环境变量"一直被忽视.
打开后我发现我当前的环境变量这样设置的:
path == E:/oraclient_1;E:/oracle_1/oradata/bin;E:/oracle_1/bin;E:/Program Files/Java/jdk1.5.0_04/bin;E:/Tomcat5028/bin;%SystemRoot%/system32;%SystemRoot%;%SystemRoot%/System32/Wbem
问题出现了.随后我该成如下:
path == E:/oracle_2;E:/oracle_2/oradata/bin;E:/oracle_2/bin;E:/Program Files/Java/jdk1.5.0_04/bin;E:/Tomcat5028/bin;%SystemRoot%/system32;%SystemRoot%;%SystemRoot%/System32/Wbem
问题解决!
