【故障處理】ORA-28547: connection to server failed, probable Oracle Net admin error
------------windows 下 SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = CLRExtProc) (ORACLE_HOME = D:\app\oracle\product\11.2.0.1) (PROGRAM = extproc) (ENVS = "EXTPROC_DLLS=ONLY:D:\app\oracle\product\11.2.0.1\bin\oraclr11.dll") ) (SID_DESC = (GLOBAL_DBNAME = orcl.lhr.com) (SID_NAME = orcl) (ORACLE_HOME = D:\app\oracle\product\11.2.0.1) ) )
第一個方法解決方案:
listener.ora是伺服器端的配置oracle的檔案。
後來將listener.ora的這一行註釋掉,就行了,, (PROGRAM = extproc)
修改為:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = prod)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
# (PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.8)(PORT = 1522))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
第二種解決方案如下:
客戶端的配置檔案sqlnet.ora中配置如下:
將#SQLNET.AUTHENTICATION_SERVICES= (NTS)註釋掉,改成如下即可!
如下:
SQLNET.AUTHENTICATION_SERVICES= (NONE)
同時修改監聽器配置檔案,具體做法是: 在oracle安裝目錄下搜尋listener.ora檔案,一般在$/NETWORK/ADMIN目錄下,把主機名用ip地址代替,例如(ADDRESS = (PROTOCOL = TCP)(HOST = HBONLINE1)(PORT = 1523))改為(ADDRESS = (PROTOCOL = TCP)(HOST = 168.168.168.42)(PORT = 1523))。

監聽配置

處理
註釋掉 extproc 相關項,重啟監聽,恢復正常。

ORA-28547: connection to server failed, probable Oracle Net admin error
CHANGES
CAUSE
Wrong parameter in sqlnet.ora file.
SOLUTION
After changing sqlnet.ora parameter from SQLNET.AUTHENTICATION_SERVICES= (NTS) to SQLNET.AUTHENTICATION_SERVICES= (NONE) issue fixed.
