Example - Restarting a Failed Process from a Checkpoint File

As Cognos® Transformer processes data on the server, it maintains a checkpoint file with the extension .qy?. When a cube build or update fails, Cognos Transformer can use this .qy? file to restart processing at the point of failure.

For example, suppose you are running a quarterly model update with new data. Cognos Transformer is unable to locate one of the source files for a data source in the model, and the model update fails. You use the checkpoint file to restart processing at the point of failure.

You can use the following command to resume processing of the .py? model file:

cogtr -i go_sales.py?

If an associated .qy? file is found, it is used to restart the process.
