Toad for Oracle 11.6 64bit+注册机+连接错误解决

1、ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务 在D:\Oracle\app\Yishuihan\product\11.2.0\dbhome_1\NETWORK\ADMIN下的listner.ora文件中修改 SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1) (PROGRAM = extproc) ) ---------------- (SID_DESC = (GLOBAL_DBNAME = ORCL) (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1) (SID_NAME = ORCL) ) ----------------加上这部分，重启监听就ok了 )
