Hi @shima Avakh 

Ens.Queue class provides various methods for working with queues. Queue-related information is stored in the global ^Ens.Queue. To abort messages from a specific queue, you can use the following class method

Do ##class(Ens.Queue).AbortQueue(pQueueName)

Replace pQueueName with the name of the queue you want to abort. This method allows you to target and abort messages in a specific queue.

Here's a short method you can place in a utility class that does what you want:

ClassMethod AbortAll() As %Status
{
    Set tSC = $$$OK
    Set tQry = ##class(%SQL.Statement).%New()
    Set tSC = tQry.%PrepareClassQuery("Ens.Queue","Enumerate")
    If $$$ISOK(tSC)
    {
        Set tRS = tQry.%Execute()
        While tRS.%Next()
        {
            Set tQueue = tRS.%Get("Name")
            Write !, "Aborting Queue "_tQueue
            Do ##class(Ens.Queue).AbortQueue(tQueue)
        }
    }
    Return tSC
}

Also, one might be tempted to simply kill the ^Ens.Queue global.

Don't.

^Ens.Queue is used for other housekeeping tasks, and while killing it will absolutely remove all messages from visibility in the queue viewer, it won't change the message headers for those items from queued status to something else (like aborted or discarded). And it will very likely break other things that you really don't want to break.
