Start and Stop KHIKA

Overview

This section explains the procedure for starting and / or stopping KHIKA. It is advised to use this with discretion eg. in an unlikely event of a server reboot.

Before doing a hard reboot to the KHIKA VM, we have to shut down the KHIKA Application first, and after the VM boots, we have to restart KHIKA again.

Following is a step by step procedure for shutting down and restarting KHIKA.

Node Stop and Start Procedure

Suspend ALL the workspaces corresponding to the Node that you want to stop. This is to stop all the data collection first.

Select Node Tab in the Configure window.

Click on the manage node process button

In the “Manage Node Process” window pop up, there is a dropdown “Node Action” to select operation. Multiple Operations are shown. We can select “RESTART_NODE” for our purpose here. We can select “STOP_NODE” if we want to shut down for now and start later.

When we select either of the options of the node, the table below is populated with process names – Aggregator, Alertserver and EServer. All shall be stopped / restarted.

Please note if select any other operations, like “RESTART” or “STOP”, we have to select the process names using “Add” button. This is to start or stop individual processes.

Note : If you are shutting down the Node for maintenance purpose, node processes will start automatically after booting the Virtual machine. Only if processes does not start automatically, you can start the processes using the manage node process.
