Failed to connect to Database. Failed to connect to OM. RRS feed

  • Question

  • Hi,

    When move our HCK server to another place, the HCK can not be opened.  It prompted that "Failed to connect to Database. Failed to connect to OM."

    I checked the forum, seems there was someone encoutered this, but I can not find the user related, see below picture.

    I did not change any User name or computer name, just moved the computer(Shut down and restart), anyone can tell me the solution for this? All data are lost now.

  • A couple of questions:

    1) Are you starting HCK Studio from the controller computer or a different one?

    2) Do you know if your HCK clients are heart-beating properly?  You can see this from the Studio on the controller.

    3) Are you able to access the controller from other computers?

  • Hi Dilesh,

    1) Are you starting HCK Studio from the controller computer or a different one?

    A: It is controller computer. The one we are always using.

    2) Do you know if your HCK clients are heart-beating properly?  You can see this from the Studio on the controller.

    A:What is heart-beating?

    3) Are you able to access the controller from other computers?

    A: We did not try, it is single Server. If we can, how can we solve this?

  • Hi Felix GAO

    This failure because of lack permission.The solution is just right click on HCK Studio and run as administrator then it will work correctly.

  • Thanks, we will try that. Does the original data are kept after re-install?

    We also found if we changed the computer name, it will occur same failure. But in this case, we did not change the name.

  • I met the problem and it was fixed. The SQL server service didn't have enough RAM to start.

    Please try to add more RAM on your system.

    My HCK studio failed to connect to OM with 4GB RAM, and it was normal with 8GB RAM.
