问题追踪思路

1. sqlplus进入操作页面，提示需要输入账号密码

报错如下：

ERROR:ORA-01034: ORACLE not availableORA-27101: shared memory realm does not exist
  • 原因：
    1. 首先检查内核参数设置以及alert.log 文件
    2. 查看sqlnet.log日志
    3. 检查listener是否配置正确 命令： tnsping orcl 以上操作都是正常

2. 查看监听状态

lsnrctl status

简要日志信息

监听程序参数文件C:\Users\Administrator\Desktop\PLSQL_Developer_8.0.3.1510\instantclient_11_2\listener.ora监听程序日志文件c:\app\administrator\diag\tnslsnr\WIN-WINS2K8-158\listener\alert\log.xml监听端点概要...(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=WIN-WINS2K8-158)(PORT=1521)))监听程序不支持服务命令执行成功

3. 排查监听程序参数文件路径出现原因，跟踪到net manager

处理方案

1. 查看net manager里面路径配置

服务器位置：C:\Users\Administrator\Desktop\PLSQL_Developer_8.0.3.1510\instantclient_11_2
进入操作：开始–>Net Manager 进入

以下所有配置路径：C:\Users\Administrator\Desktop\PLSQL_Developer_8.0.3.1510\instantclient_11_2

2. 配置 tnsnames.ora文件

#tnsnames.ora Network Configuration File: C:\Users\Administrator\Desktop\PLSQL_Developer_8.0.3.1510\instantclient_11_2\tnsnames.ora#Generated by Oracle configuration tools.LISTENER_ORCL =(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = WIN-WINS2K8-158)(PORT = 1521)))(CONNECT_DATA =(SERVER=DEDICATED)(SERVICE_NAME = ORCL)))ORCL =(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.158)(PORT = 1521)))(CONNECT_DATA =(SID=CLRExtProc)(SERVICE_NAME = ORCL)))

3. 配置listener.ora文件

# listener.ora Network Configuration File: C:\Users\Administrator\Desktop\PLSQL_Developer_8.0.3.1510\instantclient_11_2\listener.ora# Generated by Oracle configuration tools.SID_LIST_LISTENER =(SID_LIST =(SID_DESC =(SID_NAME = orcl)(ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)(ENVS = "EXTPROC_DLLS=ONLY:C:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")))LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.158)(PORT = 1521))))DIAG_ADR_ENABLED_LISTENER = OFF

4. 执行命令

lsnrctl reload####### 说明：重新加载监听文件

5. 重启服务

OracleOraDb11g_home1TNSListener####### 说明：监听服务OracleServiceORCL####### 说明：oracle服务

6. 执行命令

lsnrctl status####### 说明：查看监听状态
监听程序参数文件C:\Users\Administrator\Desktop\PLSQL_Developer_8.0.3.1510\instantclient_11_2\listener.ora监听程序日志文件C:\app\Administrator\product\11.2.0\dbhome_1\network\log\listener.log监听端点概要...(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.0.158)(PORT=1521)))服务摘要..服务 "orcl" 包含 1 个实例。实例 "orcl", 状态 UNKNOWN, 包含此服务的 1 个处理程序...命令执行成功

7. 正常运行
