Overview

During upgrade and maintenance, you may want to run your PhixFlow instance whilst preventing task plans from running. There are two options you can use to achieve this:

• Prevent users starting task plans and other actions, see Restricting Access During System Maintenance. This depends on user permissions.
• Prevent scheduled task plans from starting. 

Disabling Scheduled Task Plans

You can disable scheduled task plans:

• from within PhixFlow, using the System Configuration → Advanced → Disable Scheduled Tasks 
• without logginging into PhixFlow, using the server.properties file disableScheduledTasks=false option.

From Within PhixFlow

To disable all scheduled task plans, in system configuration tick Disable Scheduled Tasks.  As long as this option is ticked scheduled task plans will not start. Scheduled task plans that are already running are not affected.

To allow scheduled task plans to run again, untick Disable Scheduled Tasks.

Before Restarting PhixFlow

To disable all scheduled task plans:

1. Edit the file tomcat\webapps\<phixflow installation directory>\WEB-INF\classes\server.properties 
2. Set disableScheduledTasks=true
3. Restart PhixFlow. 
   • Disable Scheduled Tasks is automatically ticked.
   • Scheduled task plans do not run.

Setting server.properties disableScheduledTasks=true whilst PhixFlow is running has no effect. PhixFlow must be restarted. Once PhixFlow is running, it uses Disable Scheduled Tasks to decide whether or not to run scheduled task plans. 

To allow task plans to run again:

1. Set the server.properties file disableScheduledTasks=false
   You must do this because:
   
   • clearing the Disable Scheduled Tasks check box does not change the setting in server.properties file
   • the next time the server restarts, scheduled task plans will run as normal. 
2. Log into PhixFlow.
3. In system configuration untick Disable Scheduled Tasks. 
   This restarts the scheduled task plans.
