Define Checkpoint Files

You may define up to four checkpoint files. The definition of more than one checkpoint file allows for fail-over in the case of a problem accessing a checkpoint file. When checkpoints are written, the files are examined during initialization and the most recent checkpoint selected.

To define checkpoint files

  1. Use the SOF command SET CHECKPOINTFILE.

    The checkpoint files are defined to the SOF server.

  2. Put the SET CKPTFILE command in the INITCMDS file.

    This lets the SOF server read checkpoint data during initialization.
