ACS Java Process Kill Daemon on Citrix Servers

Hello everybody I would like to mention a problem I am facing and discover right now , in the middle of a migration project , here in Piraeus Bank Greece. We have a variety of Power i Host Systems such as E880 P8 V7R3 – S824 etc. We are using ACS regarding Client perspective and the plan is to roll out ACS package to all Bank End Users through Citrix Servers. The problem identified while the End Users open a session through Citrix Farm Servers and when the session is closed , java process is still alive on the Citrix taskbar. So we have a conflict while the same user try to open another session while the java process is still open in the same server and the problem is continuously and the Citrix Server is full of open Java instances . This is happening because ACS package is using its own Java , IBM free Java and not Oracle Licensed Java (charged). We tried using Oracle Java and is working fine , but we don't want to use Oracle for several reasons. Do anyone has an idea if there is a way to kill Java Process in the Citrix Server automatically or using an IBM script in order to use IBM free Java without causing this issue and avoid using Oracle Java which is chargeable by the way ? Attached you will find wrkptfgrp and dspptf output lists. Also ACS version is V 1.1.8.1 For better communication please use the below email contacts hse@piraeusbank.gr karimako@gr.ibm.com skroumasa@piraeusbank.gr Thanks in advance Best Regards Apostolos Skroumas Piraeus Bank GR Assistant Manager of Host Systems Engineering Dept


Use Case:

This has been discussed with development and unfortunately the only solution now for you is to end that process manually in a close script on your Citrix system.
This is currently working as designed.
Just for your reference:
The background Java task holds decrypt keys for passwords stored for SESSION_DURATION, as such its existence is part of the design of the product. So we are happy to receive a RFE (Request For Enhancement),
currently it is working as designed. Here is a link on the RFE process: http://www-01.ibm.com/support/docview.wss?uid=nas8N1015918

For now you can resolve the problem by adding the following to your citrix close script, assuming you have one: java -jar acsbundle.jar /plugin=maint /killdaemon

    We have added a new property com.ibm.iaccess.ResetForMaintenanceOnExit that can be set in AcsConfig.properties. When set to true, it will end the background process when ACS exits. This is planned for our April 2019 update.

    In your post, you state that ACS is using its own Java. That is incorrect. ACS does NOT ship a version of Java. It is using the version of Java that you determined that it should use. If you are using the IBM Free Java, that was a decision that you made, and had nothing to do with ACS. If you are saying Oracle Java is working, then use that. This is a choice you have made. There are ways to have the process in the citrix environment killed, and is something that has been documented in the PMRs referenced. Also, RFE, is not a forum, its a place where you can suggest new enhancements that the community can help vote on to help development focus their efforts. I believe you are asking for an enhancement to automatically remove sessions within citrix when a user signs off. This is something that most user would not want as closing that connection would cause user to no be able to leverage sign on and user would be prompted every time.
