Starting or Stopping a Data Integration Task

Overview

After you create a data integration task, Task Status is displayed as Stopped by default. You need to manually start the task by clicking Start.

• After you start a scheduled task, ROMA Connect integrates data on a scheduled basis. During the first execution, all source data that meets the conditions is integrated to the destination. Then, full data that meets the conditions or only incremental data will be integrated based on the task configuration.
• After you start a real-time task, ROMA Connect continuously detects data changes at the source. During the first execution, all source data that meets the conditions is integrated to the destination. Subsequently, only new data will be integrated to the destination each time.

• If two data integration tasks use MRS data sources of different versions (including MRS Hive, MRS HDFS, and MRS HBase) and Kerberos authentication is enabled for the MRS data sources, the two data integration tasks cannot be executed at the same time. Otherwise, the integration tasks fail.
• In the task list, Executed indicates the time when the schedule of a created task starts to take effect.

Starting a Task

1. Log in to the ROMA Connect console. On the Instances page, click View Console next to a specific instance.
2. In the navigation pane on the left, choose Fast Data Integration > Task Management.
3. On the Task Management page, filter the task to be started based on the integration mode, task status, or task name.
   You can start the task by using either of the following methods:

   • Clicking Start: The task runs according to the configured integration mode.

     Select the task to be started and click Start above the task list. After the task is started, Task Status changes to Started.

   • Selecting Manual Scheduling: Before manually scheduling a task, ensure that Task Status is Stopped.

     Choose More > Manual Scheduling on the right of the data integration task to manually schedule the task.

     • After a scheduled task is manually scheduled, the task is executed only once, and then the task status changes to Stopped.
     • After a real-time task is manually scheduled, the task is started and the task status changes to Started. The effect of manually scheduling a real-time task is the same as that of starting a scheduled task directly.

Stopping a Task

1. Log in to the ROMA Connect console. On the Instances page, click View Console next to a specific instance.

3. On the Task Management page, filter the task to be stopped based on the integration mode, task status, or task name.
4. Select the task and click Stop to stop the task.
