Overview

There may be times when you need to shut down the Knova system to perform server maintenance tasks, for example. However, when starting or stopping Knova services, it is crucial to follow a specific sequence to avoid any erratic behavior of the Knova application. It is recommended to try to start/stop Knova automatically using the scripts provided below, and if that is not possible, follow the steps to do it manually.

Solution

• Start/Stop Services Automatically
• Start/Stop Services Manually

Start/Stop Services Automatically

1. Open the Command Prompt as an Administrator.

2. Navigate to ...\Knova\Software\Platform\Server\StartStopAll using the cd command.

   cd C:\Knova\Software\Platform\Server\StartStopAll

3. Check the trace.txt file for errors.

   If the trace.txt file contains errors, then you must shut down the system manually.

4. To start the services, run startall.bat

   C:\Knova\Software\Platform\Server\StartStopAll>startall.bat

5. To stop the services, run stopall.bat

   C:\Knova\Software\Platform\Server\StartStopAll>stopall.bat

Start/Stop Services Manually

1. To start all services manually, using Server Manager, you must start them in the following order (and always start the services on the admin server first):

   1. Hazelcast/Terracotta

   2. Knova DD

   3. Knova KS

   4. Knova NameService

   5. Wildfly

   6. Tomcat

2. Once you have done that, follow the same order to stop the services on the web servers (the Hazelcast/Terracotta service will only be on the admin server and on one backup web server).

3. To shut down all services manually, using Server Manager, you must stop them in the following order (and always stop the services on the web servers first, as this is very important for the Hazelcast/Terracotta service):

   1. Tomcat

   2. Wildfly

   3. Knova NameService

   4. Knova KS

   5. Knova DD

   6. Hazelcast/Terracotta

4. Once you have done that, follow the same order for the admin server.
