Since I need to profile the application runs in remote machine where GUI is not allowed. I started remote session profiling with JProfiler8 and ran /bin/jpenable agent in remote host. After the successful analysis I need to stop that remote jpenable jprofiler8 agent. How can I do that?
To make sure previously started agent is still in running state or not, I ran the /bin/jpenable agent again. Now I don't see previously binded JVM. So i assume it already bind with previous agent.
Unfortunately, it is not possible to unload a JVMTI profiling agent. The JVM only unloads agents when it shuts down.

Am trying to install one agent in my ECS fargate task. Along with application container i have added another container definition for one agent with image as alpine:latest and used run time injection.
While running the task, initially the one agent container is in running state and after a minute it goes to stopped state same time application container will be in running state.
In dynatrace the same host is available and keeps recreating after 5-10mins frequently.
Actually the issue that I had was task was in draining status because of application issue due to which in dynatrace it keeps recreating... And the same time i used run time injection for my ECS fargate so once the binaries are downloaded and injected to volume, the one agent container definition will stop while the application container keeps running and injecting logs in dynatrace.
I have the same problem and connected via ssh to the cluster I saw that the agent needs to be privileged. The only thing that worked for me was sending traces and metrics through Opentelemetry.

Alternative:
use sleep infinity in the command field of your oneAgent container.
My ansible playbook consist several task in it and I am running my ansible playbook on Virtual Machine. I am using ssh method to log in to VM and run the playbook. if my ssh window gets closed during the execution of any task (when internet connection is not stable and not reliable), the execution of ansible playbook stops as the ssh window already got closed.
It takes around 1 hour for My play book to run, and sometimes even if I loose internet connectivity for few seconds , the ssh terminal lost its connection and thus entire playbook stops. any idea how to make ansible script more redundant to avoid this problem ?
Thanks in advance !!
If you need to run a job on an external system that hangs for a long time and it is relevant that the task completes. It is extremly bad idea to run that job in the foreground.
It is not important that the task is Ansible or the connection is SSH. In every case you would always just "push" the command to the remote host and send it to background with something like "nohup" if available. The problem is of course the tree of processes. Your connection creates a process on the remote system and that creates the job you want to run. Is the connection gets lost, al subprocesses will be killed automatically by the OS.
So - under Windows - maybe use RDP to open a screen that stays available even after connection is lost or use something like Cygwin and nohup via SSH to change the hung up your process from the ssh session.
Or - when you need to run a playbook on that system install for example a AWX container and use that. There are many options based on your requirements, resources and administrative options.
I am developing an app in VB.NET that connects to a remote Linux server to execute a task; my application sends input data for the server program, starts the execution in the server and retrieves output information from the server when the command execution is done. I use Renci SSH.NET to exchange files (SFTP) and monitor the remote server (SSH). One of the critical tasks is to detect when the remote machine finishes command execution, and depending on the input this can take between 5 minutes and many hours.
Here is my problem: for short runs (5 minutes or less), the application runs smoothly, no problems whatsoever. But, when the execution of the remote command takes more than 10 minutes, my application does not detect any response from the server and just hangs, since it never receives the indication from the server that the remote task is finished. I use the Renci.SshNet.Common.Stream.DataAvailable property to detect when the command is done by testing if the shell prompt string is present when I invoke Stream.Read().
Now, I know that the problem is the app, since when I execute the remote code "manually" (logging into the server with a terminal app and executing the command) it finishes without problems. I suspect it has something to do with the way Renci ShellStream object polls the remote machine for data. Any ideas as to what might be happening? Thank you in advance for your answers.
I have created a task using automation anywhere to run automatically at specified times and the schedule kicks off well until i logon to the machine remotely using vpn access, when i start loging on to the machine using the vpn my automatic schedules stops working after that, what could be the cause of this issue and how do i resolve it? the machine currently runs windows 7 enterpise.
Kind Regards,

Given your information, the first thing that comes to mind:
When you log into the environment hosting the bot, you essentially 'steal' the connection from the AA control room. When you then disconnect from the environment, neither you nor the control room have an active session to this environment. This in effect means the environment 'logs off' and thus no longer runs any scheduled tasks.
You would need to go to the control room and re-establish this connection.
I am implementing session replication in my application. This is old application.
I made all changes and now need to test the server switch and confirm that the objects in session is properly carried to another server in server list.
I have 1 Admin server and 2 managed servers. So the cluster is made of 2 managed server.
while testing I have to always bounce the server and test the flow of my application. This process is very time consuming. So I am looking for any other way to sway a server in and out of cluster
during runtime. I asked on Oracle support website , but they said only way to bounce the server.
How can I write a script for this?
Is there a parameter in weblogic or wlproxy plugin config file that help in this switch.
Your help is appreciated.
using Weblogic scripting tool (WLST) in script mode, you can write a script to automate the shutdown / startup of the managed server that you would like to remove temporarily from the cluster.
you create a file with .py extension which will contain the weblogic commands that you would like to run.
shutdown.py:
connect('username','password','t3://adminIP:port')
shutdown('servername')
disconnect()
startup.py:
connect('username','password','t3://adminIP:port')
start('servername')
disconnect()
to run the script from commandline:
java weblogic.WLST c:\myscripts\shutdown.py
you can put this line in a shell/batch script.
Another way is to write a Java program or an ANT script to invoke the commands using the weblogic.jar file that comes with weblogic.
If you were to change the state of a weblogic managed server from running to admin mode then also you can test the session replication.
You can do this from admin console by selecting the managed server and going to control tab and changing the state of the server to Admin. You can change it back to running from the same place.
Using WLST you can use the commands suspend and resume

http://docs.oracle.com/cd/E14571_01/web.1111/e13813/quick_ref.htm
suspending and resuming managed servers is quicker than shutting it down and restarting it again.
I have tested this at my end and it works fine, ie when I change the state to admin, my request goes to another managed server and the session is also replicated.
I have used the sample WLS cluster replication example available in wls installation.
