Advanced session properties in mapping tasks

Advanced session properties in mapping tasks

When you create or edit a mapping task that processes change records from a PowerExchange CDC source, set some advanced session properties that pertain to CDC.
In the
Advanced Session Properties
section on the
Runtime Options
page, click
+
to add each advanced session property. The following table describes the advanced session property values to add:
Advanced Property
Required Value
Commit on End of File
No
This setting avoids duplicate data from occurring on the target after a mapping task job is restarted. The default is
No
.
Recovery Strategy
Resume from last checkpoint
This setting is the only valid value. It is required to enable the recovery of change data and CDC restart information on the target after a mapping task ends abnormally or is stopped before completing change data processing. With this setting, the mapping task can resume processing change data from the point of interruption in the change data stream.
By default, recovery is disabled and the task status remains as Failed. If the task is included in a taskflow, the taskflow continues to run.
For information about other advanced session properties, see the topic "Advanced Session Properties" under Tasks > Data Integration Tasks in the Informatica Cloud
Data Integration
Help. The following advanced session properties are not supported or required for CDC:
  • $Source Connection Value
  • $Target Connection Value
  • Incremental Aggregation
  • Reinitialize Aggregate Cache
  • SQL ELT Optimization options
  • Session Sort Order
  • Cache LOOKUP() Function
  • Pre-build Lookup Cache
  • On Stored Procedure Error
  • Data Column Delimiter
  • Enable cross-schema SQL ELT optimization
    (Clear this check box.)
If you want to run a CDC mapping with restart capability, make sure that the
Allow the mapping task to be executed simultaneously
check box is cleared.
