Operating commands for Compatible FlashCopy
Compatible FlashCopy supports commands that enable you to perform operations from the zSeries
and S/390 host systems.
These commands include the following:
• PPRC TSO
• DFSMSdss
• ICKDSF
• ANTRQST Macro
• z/VM CP
For detailed information on using these operating commands, see the IBM user documents.
PPRC TSO commands
PPRC TSO commands include the following:
• 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
DFSMSdss commands include the following:
• 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.
ICKDSF commands
ICKDSF commands include the following:
• FLASHCPY ESTABLISH
• FLASHCPY WITHDRAW
• FLASHCPY QUERY
• FLASHCPY QUERY RELATIONS
