Issue/Introduction

Attempting to set the maximum number of allowable custom attributes using steps in the TechDocs guide does not work:

TechDocs : DX NetOps 25.4 : Change the Number of Allowed Custom Attributes

Error is generated in the DA netops-data-aggregator.log:

Environment

DX NetOps Performance Management 25.4.4 or later

Resolution

In the past, apache-karaf was case-insensitive but springboot, which we now use in 25.4.4 and going forward, is case-sensitive for config option names. So, in the file:

<IMDataAggregator_Home>/config/com.ca.im.item.custattr.CustAttrColumnCache.cfg

 

The initial 'm' in the following lines needs to be lower case:

maxIntegerColumnsPerItemType=
maxStringColumnsPerItemType=

 

Make sure to use the same case-sensitive string and to restart the dadaemon process for it to take effect:

systemctl stop dadaemon
systemctl start dadaemon
