Summary

After upgrading from Network Node Manager (NNMi) v9.1x to NNMi v9.2x, previous property file changes could not be preserved in %NnmInstallDir%\misc\nnm\props\shared\nms-disco.property file.

Error

Before upgrading, there are some changes in %NnmInstallDir%\misc\nnm\props\shared\nms-disco.properties file, like below:

#!com.hp.ov.nms.disco.suppressFDBconnections=false
com.hp.ov.nms.disco.suppressFDBconnections=true   -------> added line

but after upgrading from NNMi v9.1x to NNMi9.2x, previous changes was disappered, just only below line was left:

#!com.hp.ov.nms.disco.suppressFDBconnections=false

%NnmInstallDir%: <drive>\Program Files (x86)\HP\HP BTO Software
%NnmDataDir%: <drive>\ProgramData\HP\HP BTO Software

 

 

Cause

In Network Node Manager (NNMi), we can see nms-disco.properties file in the two places:

NnmInstallDir/misc/nnm/props/

NnmDataDir/shared/nnm/conf/props

but these two places have different role for property files.

for NnmInstallDir/misc/nnm/props/ directory, the customer should never change configuration

parameters in NnmInstallDir/misc/nnm/props - in fact they should never be aware that this directory even exists. 

These files will get overwritten with each new NNMi product release.

Fix

We should change nms-disco.properties file which located in NnmDataDir/shared/nnm/conf/props

NOT NnmInstallDir/misc/nnm/props/.
