Rules and guidelines for running a synchronization task

Rules and guidelines for running a
synchronization
 task

Use the following rules and guidelines when you run a
synchronization
 task:
  • Verify that the source and target definitions are current. If the source or target no longer contains fields that are mapped in the field mapping, the
    synchronization
     task fails.
  • You cannot run multiple instances of a
    synchronization
     task simultaneously. If you run a
    synchronization
     task that is already running, the
    synchronization
     task fails with the following error: 
    Data synchronization task <Data Synchronization task name> failed to run. Another instance of the task is currently executing.
    If you configured the
    synchronization
     task to run on a schedule, increase the time interval between the scheduled tasks to prevent multiple instances of the
    synchronization
     task from running simultaneously. If you run the
    synchronization
     task manually, wait for the currently running instance of the
    synchronization
     task to complete before starting it again.
    You can view currently running
    synchronization
     tasks on the
    All Jobs
     or
    Running Jobs
     page in
    Monitor
     or on the
    My Jobs
     page in
    Data Integration
    .
  • The
    synchronization
     task does not load any data into an IBM DB2 target if one or more records fails to load.
  • When you use an active mapplet with a
    synchronization
     task that includes a saved query, the
    synchronization
     task ignores the configured target option for the task and inserts data to the target.
