Practical implementation of Concurrent Sessions in Control Room

Babjee24 — Mon, 24 Apr 2023 07:09:41 GMT

Hi All,

I need help in understanding concurrent sessions on the same Machine/VM.

For instance I've a license that has the capability to have 10 concurrent sessions and unlimited number of run time resources. I've created 2 objects in Background mode with a single action in both of them. I now created two different processes with one Background object action called in each, when I tried running both the processes one is getting completed and another is getting terminated as shown in below screenshot.

Though I've the lic capacity to have 10 concurrent Background sessions why is one process getting terminated.
Following screenshot shows my lic capacity:

Hi babjee vangipurapu,

Virtual machine which you are testing have two run time resources or 1 run times resource?

Hi @Harish M ,

It has only 1 run time resource

Hi babjee vangipurapu

Is there any reference object having exclusive mode( double check once whether all the reference object was also set as back ground)

In order to run concurrent session on the same vm you might need to have run times resource running on different ports some thing like / port 8182 and 8183 on the same virtual machine.

Hi @Harish M ,

There are no exclusive objects in the processes for sure both the processes use only Background Objects.
And I can see only one resource PC during the BOT run

Hi @Babjee Vangipurapu ,

Did you crosschecked the Run modes used in those objects? By default, it is exclusive as shown below.
For Background objects, you to have set the Run mode to Background.

Hi @esaugos ,

Yes, I have selected the object run mode as Background itself

Hello @Babjee Vangipurapu

Based on what you have described, running 2 background processes on a single Digital Worker (Runtime Resource) should work for you.

Things to try to identify the issue:

#1 For the Terminated Session, what does the Session Log say about why it was terminated?
This may give a clue to what the issue is.

#2 You will be able to run two instances (sessions) for the same process, can you run your working BG2_Process twice on the same Resource (Digital Worker)?
If not, see #1 for the error
If yes, then it sounds like your BG1_Process is the issue.

#3 Can you run your BG1_Process process on the Resource?
If yes, then try #4
If no, then it sounds like your BG1_Process is the issue.

#4 Can you run 2 instances (sessions) of your BG1_Process process on the Resource?
If not, then you’ve narrowed the issue down to something with the BG1_Process process.
If yes, then the only other thing is a conflict between your BG1_Process and BG2_Process

I hope this helps...

Kind regards

HI Babjee,

Just curious what is the terminated session log indicating when you are trying to run 2 processes concurrently in one VM ?
