TAM ESSO and support for Java

TAM ESSO supports Java applications for sure, but if you haven't deployed it yet there are a few issues which you might need to be aware of.

First, when you install AccessAgent on a computer, the installer will try and find any instances of Java on the computer and will add support for that Java. After installing AccessAgent find the directories on your computer where Java is installed and you should see the following files at these locations:


Some applications may get installed with their own Java. If the AccessAgent installer does not detect that Java then you will have problems profiling the Java application and AccessAgent will not detect the profile for SSO.

If you wish to add support for the application after AccessAgent has already been installed there is a script which you can run located here:

C:\Program Files\Encentuate>JavaSupport>

For example lets say you have a Java application called "XYZ App" installed which has its own instance of Java under its own program directory. Launch the script specifying the location of the JRE:

C:\Program Files\Encentuate\JavaSupport>JVMSupport.vbs /d C:\Program Files\XYZ App\jre

Going forward you would probably want to have AccessAgent support this Java on any machines with this application installed without having to go to all of your workstations to run this script. The JVM paths can be specified at the time you install the AccessAgent on end user machines. The SetupHlp.ini contains parameters for specifying these JVM paths. This part is clearly documented in the TAM ESSO installation and administration guides, but I'll mention it here:

SetupHelp.ini parameters:


AccessAgent Seems Slow?

One thing that seems relevant here is that AccessAgent can appear noticeably slower when profiling or testing with Java applications. By default AccessAgent is logging all activity at LogLevel=3. This is a pretty good level for debugging. However, normally for production you probably do not need the logging to be at this level. AccessAgent performs considerably better at LogLevel=1 or 0. So if you see issues with the profiles appearing slow especially for Java applications, you may want to go ahead and drop that LogLevel down:


BTW, if AccessAgent seems slow, it may not be the fault of the LogLevel or TAM ESSO at all. There are other outside factors which could affect the performance of AccessAgent including some antivirus, but in most cases you will not notice any change in performance of your desktops with TAM ESSO. With all that is going on it performs excellent.
