Resetting bitmaps

To run the Bitmap Resetter utility to reset bitmaps, you must code the EXEC statement and DD statements, and optionally control statements to control the behavior of the utility.

1. Optional: Take an image copy of the database.

   The Bitmap Resetter utility changes the bitmap data. Therefore, it is recommended that you run image copy before you run the utility.

2. Prepare JCL for the Bitmap Resetter utility, and code the EXEC statement and DD statements to meet the JCL requirements of the Bitmap Resetter utility.

   For more information about the EXEC statement and DD statements, see Bitmap Resetter JCL requirements.

3. Optional: Code the control statements in the HPSIN data set.

   For more information about the control statements, see Bitmap Resetter control statements.

4. Submit the job.
5. Check the output reports and messages, and ensure that the job ran successfully.

   For more information about the reports, see Bitmap Resetter reports.
