rac expdp导出时报错: ORA-31693: Table data object "scott"."dept" failed to load/unload and is being skipped due to error: ORA-31617: unable to open dump file "/home/oraclerac/dump_dir/oravs_expdp_05.dmp" for write ORA-19505: failed to identify file "/home/oraclerac/dump_dir/oravs_expdp_05.dmp" ORA-27037: unable to obtain file status 错误原因: 在RAC环境下如果PARALLEL参数设置大于1,进程会在RAC的各个节点上进行导出,如果导出目录不共享的话就会报错。 解决方法: 1、设置为共享的directory; 2、导出语句添加cluster=n选项,指定只在本地导出;
