weblogic配置数据源问题 Message icon - Error An error occurred during activation of changes, please see the log for details. Message icon - Error weblogic.application.ModuleException: Message icon - Error [BEA][Oracle JDBC Driver][Oracle]ORA-12505 Connection refused, the specified SID (ORCL) was not recognized by the Oracle server. 在配置完之后总是出现这种问题,我的ORCL数据库在注册表也启动了啊,为什么总是说SID的问题啊。那为大神帮小弟解决啊
