Issue/Introduction

The portal shared.js file is growing in size and is causing performance problems as the end users browser downloads this file.  This has resulted in the login times increasing from a couple of seconds to a minute or more.

Cause

Component : CA IDENTITY SUITE (VIRTUAL APPLIANCE)

Resolution
