Release automation tab not available - Cannot add duplicate collection entry

Products

• CA Automic Workload Automation - Automation Engine

Issue/Introduction

After an upgrade or system change, the Release Automation tab is no longer available within the AWI.

The AWI logs show an error similar to:

Cannot add duplicate collection entry of type 'add' with unique key attribute 'name' set to 'P3P'

(The attribute may not specifically be P3P)

Environment

Release : 12.3

Component : ANALYTICS ON PREMISE

Cause

improper configuration of IIS

Resolution

This can be caused by a misconfiguration in IIS. The below is an example to resolve if the issue is P3P:

1.) Go to C:\Windows\System32\inetsrv\config and open the applicationHost.config

Search for:

<httpProtocol>
            <customHeaders>
                <clear />

Within that section, if there is anything labeled P3P, backup the file and remove that line.

2.) Go to C:\inetpub\wwwroot and open the web.config.

Search for P3P and if anything is found, backup the file and remove that line.

At this point restart IIS
