使用expdp导入数据到Rac环境，parallel 并行为4，发现导入报以上错误，分析发现Rac环境使用并行导入时会尝同时写数据库到两个节点，如果目录在本地磁盘，
则导入时候会报此错误。（导出时也存在此问题）
解决办法是在导出导入的时候加上cluster参数等于N进行单节点导入操作。
即：impdp \'/ as sysdba\' directory=db_backup dumpfile=newdb.dmp logfile=newdb.log parallel=4 content=all full=y cluster=n

导入的同时出现以上错误，根据Mos [Doc 1270847.1]描述是由于这些表上存在物化视图，建议使用TABLE_EXISTS_ACTION=APPEND参数导入数据；
此参数默认是SKIP。
