Scheduling automation scripts to run as part of cron tasks

Cron tasks are jobs that run automatically on a fixed schedule on the application server. For example, the ESCALATION cron task processes escalations to ensure that critical tasks are processed on time. You can use several predefined cron tasks and you can also define new cron tasks. For new cron tasks, you must provide a Java™ class implementation that contains the business logic that is executed on a schedule.

Automation scripts support new cron tasks by providing the com.ibm.tivoli.maximo.script.ScriptContask Java class. By using this Java class reference in your cron task definition, you can attach an automation script that provides the business logic that is executed by the cron task.

• Creating cron tasks that run automation scripts
  
  When an automation script runs as part of a cron task, the automation script does not require a launch point. You reference the com.ibm.tivoli.maximo.script.ScriptContask Java class in your cron task definition, and then you can attach an automation script to the cron task.
• Variables in automation scripts that run as cron tasks
  
  You can use only variables of type IN because automation scripts that run as cron tasks are unassociated with Maximo® business objects. You can also use the implicit variables scriptName, qName, and runAsUserInfo.
