Spotfire Server: Verifying JVM settings for the Spotfire server process

To check the current JVM settings for the Spotfire Server or Spotfire Node manager you can run the following command where PID is the process ID of the Spotfire process:

jcmd PID VM.flags

Example output:

jmcd 2956 VM.flags

-XX:+AlwaysPreTouch -XX:CICompilerCount=4 -XX:ConcGCThreads=2 -XX:+DisableExplicitGC

-XX:+UseG1GC -XX:-UseLargePagesIndividualAllocation

jcmd is located in the following directory <Spotfire Server directory>/jdk/bin

On Linux you can check the PID by looking at the status for the service:

systemctl status spotfireserver-14.0.6.service

On Windows you can run the following in Powershell to get the PID:

Get-WmiObject win32_service | ?{$_.Name -like '*spotfire*'} | Select-Object -Property *
