Hi David,

 

Plz help to correct below command:

C:\Program Files\Java\jdk1.8.0_191>java -Xbootclasspath/a:lib\tools.jar -jar C:\Data\AppDynamics\AppServerAgent-4.5.18.29239\javaagent.jar 18552

 

I want to run on Windows OS only this Java agent. My Java applivation is running on tomcat server.

on windows. I tried Machine agent, it worked fine on my windows system.

 

Thank,

Rakhi

Hi there, I see the following message:

 

"Caused by: java.io.IOException: no such process"

 

Are you sure you have the right process id in the command? on windows you can find the process id using the "tasklist" command.

 

Kind Regards,

 

David

Hi David,

 

C:\Program Files\Java\jdk1.8.0_191>java -Xbootclasspath/a:lib\tools.jar -jar C:\Data\AppDynamics\AppServerAgent-4.5.18.29239\javaagent.jar 1432
Attaching to VM [1432]
agent path >>>C:\Data\AppDynamics\AppServerAgent-4.5.18.29239\javaagent.jar

C:\Program Files\Java\jdk1.8.0_191>

 

Above is Working for me  now, I started my tomcat where my application is running, 

C:\apache-tomcat-8.5.51\bin>startup.bat restart
Using CATALINA_BASE: "C:\apache-tomcat-8.5.51"
Using CATALINA_HOME: "C:\apache-tomcat-8.5.51"
Using CATALINA_TMPDIR: "C:\apache-tomcat-8.5.51\temp"
Using JRE_HOME: "C:\Program Files\Java\jdk1.8.0_191"
Using CLASSPATH: "C:\apache-tomcat-8.5.51\bin\bootstrap.jar;C:\apache-tomcat-8.5.51\bin\tomcat-juli.jar"
C:\apache-tomcat-8.5.51\bin>

 

I could see a new window for tomcat, and there it is showing:

Great thanks, you're missing a crutical argument (after the process id), see below:

 

java -Xbootclasspath/a:"C:/Program Files/Java/jdk1.8.0_151/lib/tools.jar" -jar C:/appdynamics/AppServerAgent-4.5.8.25115/javaagent.jar 14760 appdynamics.controller.hostName=somehost,appdynamics.controller.port=someport,appdynamics.controller.ssl.enabled=false,appdynamics.agent.accountAccessKey=somevalue,appdynamics.agent.applicationName=Doughuts,appdynamics.agent.tierName=DT1,appdynamics.agent.nodeName=DN1,appdynamics.agent.accountName=someaccount

 

Kind Regards,

 

David
