                         Patch Date: 2015-08-11

Note:
The Installer of this patch was updated on Jan. 9th, 2017 to fix the following issue.

* 3907712

SYMPTOM:
The installer fails to install the patch of the base package on the node that 
has a Maintenance Release (MR) installed. 

DESCRIPTION:
If a node already has a Maintenance Release installed, the installer aborts the 
installation on the node with the following error message:
'SFCFSHA 6.2.0 does not appear to be installed or licensed'.

RESOLUTION:
The code of the installer is now modified to allow the P-patch installer to 
install the base patch on the nodes, even if they already have a base and 
Maintenance Release installed.

SYMPTOM:
