Issue/Introduction

While upgrading DX NetOps Network Flow Analysis you may run into an issue where the CA Performance Center SSO Service (or Performance Center SSO Service or DX NetOps SSO Service) will not start.

When looking at the <installdir>\portal\sso\logs\wrapperxxxxxx.log you may see:

Resolution

The <installdir>\portal\jetty\lib folder was completely missing on this machine. There were no log messages to indicate why during the upgrade the, 'lib' file would not be created. To resolve this, simply zip up a, 'lib' folder from another machine on the same version of NFA (post-upgrade) and extract it into the directory. This will allow the service to start.
