Issue/Introduction

Unable to view EMC SMARTS Notifications in Frontend Server
Frontend displays error  CAS Session Expired, need to renew proxy ticket  when trying to view EMC SMARTS Solution Pack Notifications report view in M&R.

Environment

MnR - 7.x

Smarts - 25.x 

Cause

This error may occur if the request URL service ticket assigned by the EMC SMARTS SAM / EMC MnR authentication mechanism has exceeded the configured expiration.

Resolution

The default expiration (10 seconds) may need to be increased depending on the environment e.g multiple Frontend servers, high latency.

The proxy ticket expiration period is set by the M&R configuration file below :

<APG>/Web-Servers/Tomcat/Default/webapps/cas/WEB-INF/spring-configuration/ticketExpirationPolicies.xml

Refer to the below section of the file :

==
<!-- Expiration policies -->
    <util:constant id="SECONDS" static-field="java.util.concurrent.TimeUnit.SECONDS"/>
    <bean id="serviceTicketExpirationPolicy" class="org.jasig.cas.ticket.support.MultiTimeUseOrTimeoutExpirationPolicy"
          c:numberOfUses="1" c:timeToKill="${st.timeToKillInSeconds:10}" c:timeUnit-ref="SECONDS"/>
==

Increasing the "timeToKillInSeconds" parameter period resolved this particular scenario. The above period is set to 10 seconds.
