Issue/Introduction

Data Aggregator server

Error in Exception.log post upgrade

Environment

21.2.8

PMINST : Performance Management Installations

Cause

Data Aggregator is looking for keystore file under %DA HOME%/apache-karaf-4.3.3/etc

but it is unable to find the file.

Because the customer used a custom name keystore_file.ks, and the upgrade is looking for keystore specifically.

Resolution

Rename the keystore_file.ks under %DA HOME%/apache-karaf-4.3.3/etc to keystore

edit system.properties under %DA HOME%/apache-karaf-4.3.3/etc folder

Change it From 
javax.net.ssl.keyStore=${karaf.home}/etc/keystore_file.ks
javax.net.ssl.keyStorePassword=changeit
javax.net.ssl.trustStore=${karaf.home}/etc/truststore
javax.net.ssl.trustStorePassword=changeit

Change it To 
javax.net.ssl.keyStore=${karaf.home}/etc/keystore
javax.net.ssl.keyStorePassword=changeit
javax.net.ssl.trustStore=${karaf.home}/etc/truststore
javax.net.ssl.trustStorePassword=changeit

Recycle the Data Aggregator service
