Multiple idle sessions for 'viewpoint' Topic by JustMe 24 Jul 2015 idle sessions, viewpoint

Good morning,
Our production system is monitored by a different viewpoint server that our dev/test system.
I often see multiple sessions for user 'viewpoint' and some sessions will be idle for several days.  This morning, I noticed two sessions that have been idle for over 30 days.
 
Can anyone explain why that is and if it is okay to abort those sessions?

SQL and Explain sometimes not visible in query monitor Topic by Duri83 24 Apr 2013 viewpoint; session monitor; explain; plan; collection; rates; rate;

Hello VP experts,
We have noticed a weird behaviour after VP and DB upgrade to version 14. Our VP is now V14.00.00.05-b49 and DBs are on 14.00.02.05 and 14.00.03.03.
The problem is that sql and explain texts are quite often not visible in VP (usually when you need to see they are not there ^_^)

TASM Exception and TASM Filters Topic by usmans 15 Jul 2013 TASM Filter, TASM Exception

Hello all,
Is there any way in TASM to set up an exception to abort queries based on the time in which they are in "acive state"?
For example, if a query is in delayed state for half an hour and then it goes into active state (the total time on system is half hour but I would consider this the start time and if the start time crosses 1 hour, the query should abort)

Definition of 'Active Time' seconds in Session Alert Topic by DannyChin 07 Jul 2015

I setup an alert to abort queries running over 30 minutes. The settings are 'Alert Rules' = All, 'Active Time is greater than 1800 seconds', 'Alert Action' = 'Abort Session'. Viewpoint abort the session after less than 1 minute. Does the 1800 seconds represent elapsed time or CPU time?

How can users abort their own queries without being able to abort anyone else's? Topic by Jeanne-Anne 19 Dec 2011 abort session

I have power users to whom I have given Viewpoint access. I want them to be able to abort their own queries, but I do not want to grant them a general ability to abort queries. I have activated for them the "abort query" priv in the My Queries portlet, but it won't allow them to abort when it connects to the database because I have not granted them abortsession.
