Disaster Recovery Troubleshooting

The following are possible troubleshooting scenarios that could happen.

The Reindex Task Marked as Canceled Following a DR Transfer

In the following scenario, the Reindex task might fail. If this happens, you will need to run the Reindex task manually.

  1. The Production server goes down.
  2. The user marks the server Inactive in the server installer, which will toggle the parallel server in the DR environment to Active.
  3. The Reindex activities task starts automatically (this is run by the Scheduled Task Handler service).
  4. The server where the Scheduled Task Handler service is running goes down.
  5. The Reindex task is automatically canceled.

Action

In this specific scenario, and only if the Reindex task was canceled, create a new reindex task manually. This can be done from the Administrative Client Health Center screen.

Unable to See Events

Symptom

The following error displays in a log file while you attempt to install the monitoring connector:

ERROR, WBX.whiteOPS.Agents.FilesMiniFilterActivity Monitor.FileMiniFilterActivity MonitorManager,connect, An unexpected error occurred while you attempt to start the mini-filter: System.DllNotFoundException:Unable to load DLL 'wbapi.dll': The specified module could not be found.

Reason

Visual C++ 2010 redistributable package was not installed as part of the Activity Monitor service installation.

Solution

Perform Step 3 of Activity Monitor Installation, Windows Server Core.

The Application is Not in the List of Collector Installation Managers

Symptom

The application does not appear in the dropdown list of the Collector Installation Managers in Activity Monitoring.

Reason

Either:

  • The application was not defined.
  • The Host Name (as defined in section 5.11) does not match the server's short name on which the Collector Installation Manager was opened.

Solution Steps

  1. Create the application if it does not exist.
  2. If the application already exists, ensure that the Host Name is correct.
