1.在RAC单节点执行expdp,出现ORA-31693 ORA-31617 ORA-19505 ORA-27037错误

2.查找解决方案

在MOS上使用关键字“expdp ORA-27037”查找文章:

DataPump Export (EXPDP) Fails With Errors ORA-31693 ORA-31617 ORA-19505 ORA-27037 In a RAC Environment (文档 ID 1597395.1)


SYMPTOMS

Customer receives the following errors:

ORA-31693: Table data object "W7JCR_INTER"."ICMUT01102001" failed to load/unload and is being skipped due to error:
ORA-31617: unable to open dump file "<dumpfile name and path>" for write
ORA-19505: failed to identify file "<dumpfile name and path>"
ORA-27037: unable to obtain file status
Solaris-AMD64 Error: 2: No such file or directory
Additional information: 3


Note:
It is possible for this to occur on other operating systems since it is a mount point. The OS specific errors may therefore be different.

CAUSE

The problem occurs when Datapump Export is being performed on a multi-node RAC where the dumpfile destination is not shared to all nodes for access.  Since multiple nodes will be running the Datapump job, ALL nodes must have access to the mount point where the dump file will be written.
 
The issue is addressed in the following bug report which was closed with status 'Not a Bug':
 - DATA PUMP UNABLE TO OPEN DUMP FILE ORA-31617 ORA-19505 ORA-27037

SOLUTION

1. Share/mount the dumpfile destination with all RAC nodes performing the expdp

- OR -

2. Use CLUSTER=N during Datapump so it will only run on the node which has the mount point and permissions to write to it.



显然,问题是因为在单个节点备份的路径对RAC集群的其他节点不可见而导致的,所以需要通过修改备份路径或者增加CLUSTER=N参数进行解决。这里由于路径已经固定,所以选择后一种方法进行处理。

3.问题处理

修改备份命令,增加CLUSTER=N参数后重新执行:
