Unattended Mode

LailaAl-Sheikh — Mon, 17 May 2021 12:33:00 GMT

Hi

I'm trying to run Process using unattended mode , which contains elements which are spied through Region Mode. It's running fine when we are running this using Control Room (Attended Mode), but not running in unattended mode for the element spied through region mode. Please suggest what settings are required to achieve this functionality.

Best Regards,

Hello, could you validate the VM resolution? generally this can make it difficult to locate the element speculated as REgion, a good practice is whenever you initialize the process that contains Region elements, it is to validate if the resolution of the VM is in accordance with what was developed.

Hi, I don't use the VM. I connect to my Blue Prism through a Remote Desktop, And The elements in the process which are spied through Region Mode are not working in untended mode
Please, Do you have any recommendations for the elements working in an unattended mode to work properly? And I want to make sure if we have a way for the elements which are spied through Region Mode to running in the unattended mode? Or this thing is impossible ?

It would be better to use a VM viewer application such as VSphere to login to the VM. The reason for this is that when you login to the VM via Remote Desktop, it may change the resolution to the one that you set in the Remote Desktop configuration which may be different than the default resolution of the VM. Alternatively you can set the resolution in the Remote Desktop Configuration(Display Tab) to the same resolution as the default resolution of the VM.

Also if using the Remote Desktop the only option then it would be advised that you logoff and login in the machine using the relevant BP processes from Control room before you try a test run of your BP process.

So, There's no way to work the element in unattended mode using a Remote Desktop???

When I checked options for remote desktop app I found this settings if I can check some setting to run the unattended mode (Note: I attached the screenshot for option of remote desktop)

What is the default resolution of the VM that you are trying to run from Control Room? What is the resolution that you are using to remote desktop into the system for development? What exactly is not working when you say bot is not running in unattended mode? Is there a problem running from Control room or Remote Desktop?

Hi Laila,

The issue you are experiencing is because of the Screen Resolution changes when you close the Remote Desktop Session.

It is a bit difficult to explain but you have to imagine your virtual machine (Remote Desktop) has two states.

You are signed IN to the machine through Remote Desktop (The screen resolution match YOUR PC screen resolution)
You are signed OUT of the machine. It has a default screen resolution (Usually a very low resolution to save resources)

This can be resolved by changing the Default Screen Resolution of the machine.

You may need Administrator Rigths to the machine in order to change it.

How are you running it when doing unattended? Is the machine logged out and you trigger Login Agent to log the machine in and then you run the automation?

Do you get a specific error?

Typically the only problem I've run into with Remote Desktop is that Blue Prism can no longer automate the UI of the interactive Windows session if you disconnect from the RDP session. Instead, you have to log out of the session and then trigger a separate session to log in without RDP and run the automation. This is a known thing for any RPA tool specifically for Remote Desktop sessions because it does not create sessions the same as when a user logs in (locally) to the machine.

Hi Simon, I tried Your advice and changed the Default Screen Resolution of the machine, but it didn't work.

Could you try determine what is the Screen resolution of the machine when you are signed into the virtual machine using RDP.
and also check what it is when it is running as unattended.

As other point out it is very important you signout of the VM, and use the Login Agent to sign into the VM.

Could also be after you changed the Regedit settings you have to restart the VM for it to take effect.

You can create a Process which output the results of the following VBO Utility - Environment - Get Screen Resolution

or call this type of:
code dim S As Size = Screen.PrimaryScreen.Bounds.Size
Horizontal_Resolution = S.Width
Vertical_Resolution = S.Height

Hi Dave,
I make a logout through the login agent, and then I put a scheduler for running the process that I want to work in unattended mode, and shows me the following error: "Internal: failed to implement step 1 in the navigation phase 'ENTER BTN entry' on the 'login' page - handle is invalid", This error appeared on the element identified by region mode.

Just to make sure when you say:
"I make a logout through the login agent, and then I put a scheduler for running the process"

The schedule contains Log in - Login Agent.

Also could you try enable screenshot for that EXception stage so you can see what happened with a screenshot. This will show you if the Screen resolution is off

Hi ,

Is your issue reolved?, Im also facing same issue,

Issue : BOT is running fine from control room in attended mode but if i schedule it or trigger it from another VM via control room its getting faild at the step where the elements are spied in region mode.

My tried ways below
1. Default Resolution is 1024 x 768, i tried running the process from control room via RDP login in attended mode by changing resolution to default in RDP display settings, it runs without any issues but fails again if i close the RSP.
2. I tried to logout and login via login agent to if that works but im getting below errors while running login agent.
a). LOGOUT code is working fine but LOGIN code getting (refer screenshot 1 : login code error). Server was in Logged out mode.
b). I guess the Login agent is not running properly in my second server, it goes offline as soon as resource pc is turned off instead of going to Logged out mode like server 1. (Refer screenshot 2 : Resource PC Error).

Hi Vinothkumar - it looks like you Login Agent is not working properly, maybe due to some config problem. When you run the Logout process what you should see is the Resource PC go offline temporarily and then come back online after around 30s. What should happen is that as Windows logs out, it closes all apps started by the user, and in the background the Login Agent service should recognise that the user is logged out and restart the Resource PC. But if the service isn't running or is not properly configured, then it won't be able to restart the Resource PC. When the machine reboots the service should start the Resource PC automatically.

Assuming you fix that, then the above conversation about resolution and session sis valid. If the 'runtime' resolution differs from the 'design time' resolution, then it's unlikely your surface automation will still work. And if you connect to the machine with RDP, then you will need to run logout/login to restore the Windows session for BP. Disconnecting from RDP has the effect of destroying the Windows desktop, leaving BP with nothing to 'see'.
