在一次集群测试中，发下一个现象，就是 asm实例启动报错，发现无法找到spfile文件， 示例如下： ``` SQL> show parameter spfile NAME TYPE VALUE -------------------------- ----------- ------------------------------ spfile string ``` 也就是asm实例启动时为使用该参数。 根据Oracle官方文档，当Oracle ASM搜索初始化参数文件时，搜索顺序是 - gpnp配置文件中指定的初始化参数文件的位置($ORACLE_HOME/gpnp/hostname) - 如果没有在gpnp文件中找到，则搜索 $ORACLE_HOME/dbs/目录下spfile相关文件。或者指定pfile文件。 Oracle ASM实例无法找到spfile文件的原因之一是以下错误: ``` ERROR: -5(Duplicate disk OCR_VOTE:OCR_VOTE_0001) ``` 或者是asm使用了默认的参数设置，具体如下： ``` NOTE: No asm libraries found in the system ERROR: -5(Duplicate disk OCR_VOTE:OCR_VOTE_0001) <--- * instance_number obtained from CSS = 1, checking for the existence of node 0... * node 0 does not exist. instance_number = 1 Starting ORACLE instance (normal) LICENSE_MAX_SESSION = 0 LICENSE_SESSIONS_WARNING = 0 Private Interface ... configured from GPnP for use as a private interconnect. ...
