网上搜索资料，解决方法包括设置事件10298 level 32，alter system set event="10298 trace name context forever, level 32" scope = spfile;打补丁：5146667，或者在mount的时候设置参数：rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,actimeo=0。在solaris系统上tcp参数不可用。由于是生产系统，尽量采用不停数据库来解决，重新mount。1 umount目录umount /epmhis2 mount目录加一些参数mount -F nfs -o rw,hard,nointr,noac,vers=3,rsize=32768,wsize=32768 IP地址:/epmhis /201005213 重新expdp导出文件到NFS目录Export: Release 10.2.0.4.0 - 64bit Production on Friday, 21 May, 2010 16:41:37Copyright （c） 2003, 2007, Oracle.
