FDRARCH DUMP Statement
DUMP statement
The DUMP statement causes a formatted backup copy of the Archive Control File to be created. This backup is not in FDR format, and can only be restored by the RESTORE statement of FDRARCH. The Archive Control File may be dumped by FDRABR in FDR format at the end of each dump TYPE=ARC operation.
The DUMP and RESTORE statements of FDRARCH can be used to move the Archive Control File to a different device type (such as 3380 to 3390) or to change its size or blocking factor. FDRCOPY or FDRDSF DUMP/RESTORE can also be used to move the Archive Control File, but will not expand or re-block the file.
