Copying deleted records (COMPRESS parameter)

 

You might want to copy deleted records to preserve the relative record numbers of records that are copied from the from-file. You can copy both deleted and undeleted records from one physical file member to another by specifying the COMPRESS(*NO) parameter on a copy command.

If you do not use COMPRESS(*NO), only records that have not been deleted are copied from the from-file.

You can use this parameter on the CPYF command only.

• Requirements of COMPRESS(*NO) parameter and the CPYF command
  To use COMPRESS(*NO), the conditions discussed in this topic must be true.

• Restrictions of the COMPRESS(*NO) parameter and the CPYF command
  You cannot specify COMPRESS(*NO) for the cases discussed in this topic.

• Details of the COMPRESS(*NO) parameter and the CPYF command
  The COMPRESS(*NO) parameter allows the system to copy more quickly because records are transferred in blocks, but this is not always true. Typically, the COMPRESS(*NO) function does not significantly affect performance.
