RMAN备份数据到NFS提示ORA-27054

今天在备份数据到NFS目录时,提示ORA-27054

在备份中发现以下错误:

在metalink上找到一个Doc,Note:424785.1。这个问题在10.2的版本中比较普遍。可通过以下三种方式进行解决:
1、设置事件10298 level 32
alter system set event='10298 trace name context forever,level 32' scope=spfile;
重新启动数据库后生效.

2、打补丁:5146667
3、mount NFS目录时加参数
rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,actimeo=0
以上参数不是对每个系统都通用。
我使用的是red linux系统，通过修改mount参数后生效
[oracle@db2 dba]$ cat /etc/redhat-release

Red Hat Enterprise Linux AS release 3 (Taroon Update 5)
