通过查询metalink id :387700.1 文档上说可能的问题有以下几种: a) The mount table (eg; /etc/mnttab) can be read to check the mount options b) The NFS mount is mounted with the "hard" option c) The mount options include rsize>=32768 and wsize>=32768 d) For RAC environments, where NFS disks are supported, the "noac" mount option is used. 文档上指出通过设置event 10298事件可以避免,不过设置event 10298需要重启数据库生效 。 检查NFS的配置,发现客户端的/etc/filesystems中未加入mount nfs文件系统的条目 增加以下条目后,重新mount,解决。 #vi /etc/filesystems /exp: dev = /exp vfs = nfs nodename = 192.168.1.20 mount = true options = rw,bg,hard,intr,proto=tcp,vers=3,rsize=65536,wsize=65536,timeo=600 account = false #umount /oraexp #mount /oraexp 建议大家以后遇到类似问题,先检查/etc/filesystems文件,这个问题都是由于大家都喜欢使用以下方式mount nfs导致。 LINUX 使用以下方法: mount -o rw,bg,hard,intr,proto=tcp,vers=3,rsize=65536,wsize=65536,timeo=600 192.168.1.20:/exp /exp aix 使用以下方法: mount -o hard,bg,proto=tcp,suid,rsize=32768,wsize=32768,noac 192.168.1.20:/backup /backup aix 参考文章 ORA-19504 ORA-27054 Errors mounting NFS file system (Doc ID 370513.1) //相关metalink 文档如下: ORA-19504 ORA-27054 Errors mounting NFS file system [ID 370513.1] RMAN Backup Fails With RMAN-03009 ORA-19504 ORA-27054 NFS file system where the file is created or resides is not mounted with correct options [ID 1472448.1] ORA-27054: NFS file system where the file is created or resides is not mounted with correct options [ID 781349.1] //另外设置10298的过程如下: 1) set the Event 10298 in the init file event="10298 trace name context forever, level 32" if you are using the spfile then the following can be done SQL> alter system set event='10298 trace name context forever, level 32'scope= spfile ;
