timeout

问题 I am trying to establish a full duplex serial communication between the RS485 port of a stepper motor controller and the COM port of my laptop. The cable I use connects to RS485 on the controller and to a USB port on my laptop. I am using a Matlab script to send and receive commands to the controller to move a stage block on a guided linear scale. While I can open the serial connection to the device and send commands to advance the stage block on the linear scale, I am unable to receive any

问题 I'm running a long process stored procedure. I'm wondering if in case of a timeout or any case of disconnection with the database after initiating the call to the stored procedure.

问题 I am developing a suite of automated tests to run on an AngularJS application using Protractor. I have never used automated testing prior to working on this task, so am still quite unfamiliar with how it works/ how to implement the tests, etc. I recently had a bit of trouble with implementing an automated click on the 'Cancel' button of a dialog that was displayed automatically when one of the tests browsed to a particular page. I have now got the click to the 'Cancel' button working

问题 I have a dynamic airflow dag( backfill_dag ) that basically reads admin variable(Json) and builds it self. Backfill_dag is used for backfilling/history loading, so for example if I wants to history load dag x,y, n z in some order(x n y run in parallel, z depends on x) then I will mention this in a particular json format and put it in admin variable of backfill_dag . Backfill_dag now: parses the Json, renders the tasks of the dags x,y, and z, and builds itself dynamically with x and y in

问题 I have a wcf service that works fine. The problem is the client. I have a little gui where the user is supposed to place the ip address of where the wcf service is located. Both the client and service are on the same network so if I am not able to connect it is because I provided an incorrect ip address or because the firewall is blocking. Anyways how can I shorten that time so that if the user types the incorrect ip he does not have to wait like 20 seconds? Here is how my app.config file

问题 I am trying to execute a function or a scriptblock in powershell and set a timeout for the execution. Basically I have the following (translated into pseudocode): function query{ #query remote system for something } $computerList = Get-Content "C:\scripts\computers.txt" foreach ($computer in $computerList){ $result = query #do something with $result } The query can range from a WMI query using Get-WmiObject to a HTTP request and the script has to run in a mixed environment, which includes

问题 Once a Login script is executed with few user, I don't see connection reset problem, whereas, when the same is run 100 users, " java.net.SocketException: Connection reset " starts throwing for very first link. What I don't understand is if there is connection problem, then it should even show the same error for single or few users as well. 回答1: This means that your server is rejecting connections because it is either overloaded or misconfigured. It is regular that you don't face it with 1
