Oracle安装连接常见错误

Posted 2021-03-15 阳光下的行者

oracle
安装注意：安装路径url不能带中文
C:app59428product11.2.0dbhome_1sqldeveloper
打开sqldeveloper的时候，需要输入java.exe
C:app59428product11.2.0dbhome_1jdkjrein

警告：PlSQL安装32 ，x86版本

常规操作：
1、关闭防火墙
2、可以ping通服务器地址
3、oracle的服务器地址为：ip+orcl实例名，如：127.0.0.1/orcl
4、启动listener服务、oracleservicesoral服务

错误处理：
1、ORA-12638: 身份证明检索失败的解决方法
开始 -> 程序 -> Oracle -> Configuration and Migration Tools ->
Net Manager→本地→概要文件→Oracle高级安全性→验证→去掉所选方法中的 "NTS" 就可以了.

或者 把sqlnet.ora SQLNET.AUTHENTICATION_SERVICES = (NTS)其中的NTS改成其它的就行；我是改成NONE.

或者 把NTS设任何值都行，也可以把sqlnet.ora SQLNET.AUTHENTICATION_SERVICES = (NTS)整行去掉。

2、本地计算机上的oracleoradb11g_home1TNSListener服务启动后停止。某些服务在未由其他服务或程序使用时将自动停止。
在环境变量里加入ORCLE_SID, TNS_ADMIN。
电脑-属性-高级系统设置-高级-环境变量-系统变量-新建
变量名 ORACLE_SID 变量值 orcl
变量名 ORACLE_HOME 变量值 E:Oracleproduct11.2.0dbhome_1（oracle数据库安装路径）
编辑Path，在path值后面追加上 ；E:Oracleproduct11.2.0dbhome_1in
之后重启电脑！重启电脑！重启电脑！

3、ORA-28547:连接服务器失败、ORA-12541：TNS:无监听程序
修改监听器配置文件，..appadminproduct11.2.0dbhome_1NETWORKADMINlistener.ora ，把主机名用ip地址代替
SID_NAME = CLRExtProc 改为 SID_NAME = orcl （orcl是实例名）
HOST = localhost 改为 HOST = 192.168.1.37
切记，服务器、客户端都要修改。

4.修改..appadminproduct11.2.0dbhome_1NETWORKADMIN nsnames.ora
两处 HOST = localhost 改为 HOST = 192.168.1.37
SID = CLRExtProc 改为 SID = orcl

5、重启oracle的上边的两个服务

6、ORA-12154：TNS：无法解析指定的连接标识符
在Oracle目录上右击选择“属性”，给已有账号赋全部权限。新添加：IIS_IUSRS用户全部权限

7.ORA-28547 连接服务器失败，可能是Oracle Net 管理错误
原因：

The listener.ora file‘s SID_LIST section may INCORRECTLY contain a "PROGRAM" line and/or an "ENVS" line for all database instances.

PROGRAM和ENVS参数的设置会导致客户端通过SID_NAME来进行连接，由此会引发ORA-28547错误

解决方法：

打开【listener.ora】文件，去除PROGRAM和ENVS，重启监听或者重启Windows

[oracle@localhost ~]$ cat  /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = orcl)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      #(PROGRAM = extproc)  #######去掉此行
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.136.211)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )

正确配置保存一份:
