WIN7 64位 oracle ORA-12514:

Posted 2023-03-17

将tnsnames.ora中这个链接的Service_Name，改为SID_Name，或将这两个字符串调换。追问

改了变成这样了

追答

服务器莫名其妙的报这个错，之前一直正常，从google获取解决方案，解决之，记录如下：

1. Open the ""/network/admin/listener.ora" file in the host,and you will see:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)
2. Add the following lines after the 7th line in the above
(SID_DESC =
(GLOBAL_DBNAME = ORACLE)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(SID_NAME = ORACLE)
)
3. At last the content of the file become to the following section:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = ORACLE)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(SID_NAME = ORACLE)
)
)
4. Save the file and restart the TNSListener service in the host. That's OK!
