To resolve a held-up operation

When you try to start or stop an application, in some cases, the start or stop operation may get held-up mid course. This may be due to VCS detecting an incorrect internal state of an application component. You can resolve this issue by using the resolve a held-up operation link. When you click the link, VCS appropriately resets the internal state of any held-up application component. This process prepares the ground for you to retry the original start or stop operation, or initiate another operation.

To resolve a held-up operation

  1. In the appropriate row of the application table, click More > Resolve a held-up operation.
  2. In the Resolve a held-up operation panel, click the system where you want to resolve the held-up operation, and then click OK.
