Oracle RAC单实例运行_Oracle 10.2.0.4 RAC故障后单台主机启动数据库
一个客户和一套Oracle 10g RAC数据库出现故障,CRS宕机，检查后发现是私网网卡坏了，但是更换网卡还需要购买，现在需要单台主机跑业务，通过手工启动ORACLE ASM实例的时候发现报错，如下：
SQL>startupSQL>ORA-27504: IPC error creating OSD contextSQL>ORA-27300: OS system dependent operation:check if cable failed with status: 0SQL>ORA-27301: OS failure message: Error 0SQL>ORA-27302: failure occurred at: skgxpcini1SQL>ORA-27303: additional information: requested interface eth1 interface not running set _disable_interface_checking = TRUE to disable this check for single instance cluster. Check output from ifcon

根据以上提示，首先在ASM参数文件中设置2个隐含参数：*._disable_instance_params_check = TRUE*._disable_interface_checking = TRUE

然后启动ASM实例，正常。再启动Oracle 数据库，发现继续类似报错，然后到Oracle RDBMS参数文件中设置1个隐含参数：*._disable_interface_checking = TRUE
启动数据库，成功。
