Database agent Installation

Database agent Installation

Hello,

The reason for my question is that I cannot install the database agent, when I run the following command I get no response:

§ nohup java -Dappdynamics.agent.maxMetrics=300000 -Ddbagent.name=DBMon-Lab-Agent -jar db-agent.jar &
attached is screen shot.

Hi Farzaneh

 

The command you are using, does not install the db agent as a service, that will start it when you reboot the machine or can be started/stopped by using linux commands.

 

The below nohup command, is just a manual way of starting the db agent, however as soon as the server is rebooted etc. The db agent service will not automatically start again.

 

What you see below is correct, it has started the db agent process in the background, and it's process id is - 31524, you can run a ps aux | grep agent command which should show you that process is running, and you will find that there is a nohup.out log file for the process.

 

If you want to install the db agent as a service instead of manually starting it as in your post you can refer to the documentation

https://docs.appdynamics.com/22.4/en/database-visibility/administer-the-database-agent/start-and-sto...

 

Ciao

Hello Mario,

 

Thanks for your answer. Indeed I have to install the Machine agent and not bd Agent.
I have already installed the Machine agent but I can't start it. I need the command to start the machine agent in Centos.

Thanks for your Help!
