First, the environment introduction:
The results of the cat/etc/issue are:

Red Hat Enterprise Linux Server release 6.5 (Santiago) Kernel \ r on an \m


GI Specific Patch information: only the GI 11.2.0.4 version number is installed. There is no GI psu that hits no matter what. No GI patch, no matter what.


Ii. description of the issue:
This is a set of rhel6.5 RAC, using the Oracle GI cluster software, using the ACFS. Acfs made the rhel6.5 file system (mount point is/xxx, for example),


EXPDP out the DMP file to the/xxx mount point. At the same time. /xxx mount points are set up for samba sharing, shared to Windows hosts (hereinafter referred to as Windows sambaclient),
The application software will perform a series of processing (zip, etc.) for DMP in the/xxx file system on this Windows Sambaclient.

The following problems are found during use:
On Windows Sambaclient, the access method is slow when the shared space is in the start-of-Execution of Windows-typed: \\rac's vip\ share name.

I searched for MoS, see for example the following article: with "ACFS on 11.2.0.4 and samba" search for keyword in mos.
There is an article in "Community search results": ACFS on 11.2.0.4 and Samba (community forum ID 3574416)
An SR (SR 3-11146797451) was subsequently submitted and confirmed by the analysis of the Dalian Gcsproject Division: The phenomenon is 11.2.0.4 version number of the GI bug, need to hit a patch to solve
This patch is: Patch 17696547

In fact. The patch is not so good to hit. There is a bit of twists in the middle.

。 I'm not sure about the details of my colleague's patch. Just heard that it wasn't going well.
