You must complete the necessary fields on the page to set up and run a database compaction job instance.

To set up and run a data compaction job:

  1. Provide values for the Name and the Description fields. Name is a required field.
  2. In the Compact trend data more than days old field, identify the number of days for which you intend to compact data. A day, as defined for this field, begins at midnight. This is a required field.
    Note: You can compact only data that is more than a week old. If you enter a value of 1-6, no data compaction will take place.

    In the Purge archived data more than days old field, specify the number of days of data you want purged from the database.

  3. Enter a value in the Working directory field. The Working directory field identifies the command's current working directory, and the directory you specify must exist. This property defaults to the working directory defined at installation.
  4. Enter values in the Output file (stdout) and Output file (stderr) fields. The stdout location indicates where messages will be stored and the stderr location indicates where error messages will be stored. To append subsequent messages to these files, select the Append option.
  5. Select the Debug log file option to obtain diagnostic details that help you debug job properties when setting up a job.
    For example, you can set this option and use the Run Now feature on the Job Summary page. Once you have submitted the job, OpenEdge Management makes debug trace file data available through the debug trace file link in the Job History section of the Job Summary page.
