I currently have v10.5.2.52 wkst installed on my laptop. I am trying to change the .lax file as you mentioned...

# LAX.NL.CURRENT.VM
# -----------------
# the VM to use for the next launch

lax.nl.current.vm=jre\\bin\\java.exe

I want to change the path to...

lax.nl.current.vm=C:\\Program Files (x86)\\Java\\jre1.8.0_171\\bin\\java.exe

what's the proper syntax?

Branched off from Upgrade the Introscope workstation to 64 bit 

Hi Manish,

Yes that syntax is valid and the spaces will also be handled seamlessly:

lax.nl.current.vm=C:\\Program Files (x86)\\Java\\jre1.8.0_171\\bin\\java.exe

Also this syntax is valid:

lax.nl.current.vm=C:/Program Files (x86)/Java/jre1.8.0_171/bin/java.exe

I thought the spaces might be a problem but when I tested my 10.5.2.52 workstation they were not

It worked with your suggestion. But when I increase the memory to 2GB, the wkst doesn't work at all. Should I be changing the min/max under window's java properties?

lax.nl.java.option.additional=-Xms2048m -Xmx2048m -Dsun.java2d.noddraw=true

Hi Manish,

You are using x86/32-bit java (C:\\Program Files (x86)) which only has a ~1400 MB practical limit on Windows although on *nix the limit is ~ 2GB.

If the Windows OS is 64-bit you will need to install 64-bit java.

If the Windows OS is only 32-bit you will have to bring down the max heap value to ~ 1400M or keep going down by increments if it still fails to start

Hope that helps

My OS is 64-bit so I will download a 64-bit java and try again.

So, downloading 64-bit java worked well. What's the suggested min/max w/ 64-bit java.

Its limit is the amount of RAM you have minus 2 GB for the OS.

So for workstation thick client, I would recommend 2 to 4 GB.  Make Xms and Xmx equal to each other.

If you're going to be dealing heavily with dashboards and the like, I would put it more towards the 4 GB.  If you're expecting 50 or so users connecting at the same time, I would up it to 6GB.

Thanks for the tip. I am starting with min/max both to be 2GB for now. Will see if I need to increase that in the future.I am the only one that works on dashboards so I know now to increase the heap size if I see perf issue for the thick client.

Thanks everyone for your help.

Incase if you want to uninstall it, I believe , you may need to restore the default JVM and then uninstall.
