This chapter describes how to perform operations using Compatible FlashCopy.
Operating commands for Compatible FlashCopy
Compatible FlashCopy supports the following commands that enable you to perform operations
from the mainframe host system:
• PPRC TSO commands:
FCESTABL◦
◦ FCWITHDR
◦ FCQUERY
To use the PPRC TSO commands, you must add the command names to the AUTHCMD PARM
of IKJTSOxx, which is a member of SYS1.PARMLIB, because the host system is protected by
RACF Facility.
• DFSMSdss commands:
COPY FULL◦
◦ COPY DS
Compatible FlashCopy supports VSAM datasets. However, when the user specifies attributes
for the copy source extents that differ from those specified for the copy target extents, DFSMSdss
invokes a different program (such as IDCAMS), and, as a result, Compatible FlashCopy may
not be able to use VSAM datasets.

FLASHCPY ESTABLISH◦
◦ FLASHCPY WITHDRAW
◦ FLASHCPY QUERY
◦ FLASHCPY QUERY RELATIONS
