Issue/Introduction

Data Aggregator shows synchronization failure in CAPM NetOps Portal WEB UI.

The following error is observed in the NetOps Portal caperfcenter_console PC service PCService.log file.

ERROR | RIB/VendorCertsCacheScanner | 2018-06-13 09:32:54,102 | com.ca.im.portal.plugins.polaris.cache.utils.DAWsCacheUtils
      | Error while connecting to http://<DA_HOST>:8581/genericWS/certifications
com.ca.im.portal.plugins.polaris.utils.HTTPWebServiceRequestException: java.net.NoRouteToHostException: No route to host

The network communications between hosts appears to work well, and /etc/hosts is configured properly. Why is this error occurring?

Environment

All supported DX NetOps CAPM releases

Cause

In the CAPM NetOps Portal server, SElinux is enabled.

Resolution

The SElinux tools must be either disabled or in fully Permissive mode in order to have a properly functioning CAPM environment.

Disable SElinux or configure it as Permissive and restart all server services.

Additional Information

Permissive is allowed as it only performs logging and doesn't actually prevent activities from taking place as required.
