The Save uncompressed file (KEEPCPY) parameter enables you to keep a copy of the original, non-compressed file in a save file. The default value is *NO. The value *YES causes the RGZACTF command to attempt to save a copy of the original, non-compressed file along with any dependent logical files. This save operation occurs just before the RGZACTF process deletes the original file and moves the compressed file into production. Specifying *YES can significantly increase the amount of time the file is not available.
The Save file (SAVF) parameter enables you to specify the qualified name of a save file to be created to contain the original file and any dependent logical files. The default value *GENERATE causes the system to create a name for the save file in the library specified. The name is in the form PSnnnnnnnn, where nnnnnnnn is a random string of letters and numbers. This file is guaranteed to be unique in that library. If you specify a name, the RGZACTF command ensures the file does not exist. The RGZACTF command will not overwrite an existing file of any kind with this save file.
