Configuring the Cron Task Configuring the Cron Task The interface table cron task, the data import cron task, and the Java Message Service (JMS) queue cron task are cluster-aware functions. By default, the cron task framework runs a task on a randomly chosen server. If you want to configure your cron task to run on a specific application server within your cluster, configure the cron task as shown in the following example. The name of the cron task instance is instance1. 1 In the Cron Task Setup application, set the TARGETENABLED property for instance1 to 1. 2 In the application server1 setup, set the -D crontaskname.instance1 to 1, and restart the server. In this configuration example, the task is not pushed to another server if the targeted server stops. To replace a stopped server, set the -D crontaskname.instance1 value to 1, then restart the application server that resumes the polling. To configure a group of servers to support failover, set the -D crontaskname.instance1 value to 1 in each server. The integration framework prevents more than one instance of the cron task from running at the same time. 188 Integration Guide
