Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS
with all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4. This bug is fixed and included in 10.2.0.4 patchset.

参照上文,修改mount参数如下:
[root@node2 bdump]# cat /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
service iscsi restart
#start_udev
modprobe hangcheck-timer
mount -t nfs -o rw,bg,noac,hard,nointr,rsize=32768,wsize=32768,nolock,proto=tcp,actimeo=0,vers=3,timeo=600 192.168.2.31:/u01/flashback/ /u01/flashback/
问题成功解决!
另外,在网上查到资料,还可以使用如下方式解决
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
我没有试验,有兴趣的朋友可以试试,
