  • Can you share more about the environment?

    OO Version
    CP Version of remote command operation
    RAS OS version
    Target OS version

    I've seen this when a connection isn't closed properly. Can you login to the RAS, open a cmd prompt, and run a ("net use") - do you see the target host listed? 
    Can you give details about the command being run? 
    Is it long-running (does run command operation time out but the process is still running on the target)?

    Can you share more about the environment?

    OO Version -- 10.60
    CP Version of remote command operation -base 1.8.0 but it was working for same for last week
    RAS OS version --no RAS neing used
    Target OS version --Windows Server 2012 R2 Datacenter

     

     Can you login to the RAS, open a cmd prompt, and run a ("net use") - do you see the target host listed? Ras not used so unable to run
    Can you give details about the command being run? not able to run
    Is it long-running (does run command operation time out but the process is still running on the target)?  NA

     

     

  • If you don't have a separate RAS you're using the built-in worker on Central - please perform those RAS checks from there. 

    If you're unable to be descriptive about the operation being executed I'm as lost as you are "not able to run" doesn't help troubleshoot the issue.

    Are you running with clustered centrals or a single node? 

    What are your inputs... what is your source/target (obfuscate but remain distinct i.e. nodeA(central) -> nodeB(win 2016 host)?

    ==>>Yes we are using only builtin worker on ras

    ==>> In flow remote command execution operator is used from Base cp. command is use to fetch a dir details and copy files from one server to other.
