Clarity PPM On Premise

Issue/Introduction

XOG Login is failing in a new install or upgrade, but was working previously. In "verbose" logging mode the error is seen:

HTTP Error: Status-Code: 400: null

ca-log shows errors like:

niku.xog (clarity:none:none:none) XOG POST failed
java.lang.NullPointerException
 at com.niku.union.utility.StreamUtils.writeToFile(StreamUtils.java:435)
 at com.niku.union.utility.StreamUtils.writeToFile(StreamUtils.java:391)
 at com.niku.xog.service.XOGSOAPServlet.doPost(XOGSOAPServlet.java:127)

Cause

Problem is caused due to the Clarity application on the server being unable to write to the temp directory on the server. As a part of the XOG process, files are saved into the temp directory and then processed.

Environment

Release : 15.8.1

Component : CA PPM APPLICATION

Resolution

In a Linux installation a specific user account would be used to start the Clarity services. Ensure this account has the ability to write to the system's temp directory.
