DFSMSdfp: Prepare for the removal of TSO copy services commands

Description

z/OS V2R2 is planned to be the last release to include a number of TSO/E-based System Data Mover (SDM) related commands. Except for the query commands (CQUERY, FCQUERY, RQUERY, XQUERY, XSTATUS), the ANTRQST API, and the XSET command, which will remain, IBM recommends that users migrate to the REXX versions of these commands.

Specifically, the following commands will no longer supported in TSO:
  • FCESTABL
  • FCWITHDR
  • CDELPAIR
  • CDELPATH
  • CESTPAIR
  • CESTPATH
  • CGROUP
  • CRECOVER
  • CSUSPEND
  • RSESSION
  • RVOLUME
  • XADDPAIR
  • XADVANCE
  • XCOUPLE
  • XDELPAIR
  • XEND
  • XRECOVER
  • XSTART
  • XSUSPEND

Steps to take

Convert existing non-query TSO commands to the REXX version using the programs provided in SYS1.DGTCLIB (ANTFREXX for FlashCopy, ANTPREXX for PPRC, ANTXREXX for XRC). Some of the command keywords are slightly different than the TSO version, and might need to be modified. For example, for full volume FlashCopy establish, you might enter the TSO command, as follows:
FCESTABL SDEVN(0F60) TDEVN(0F61)
To use the REXX interface, you can enter:
ANTFREXX FCESTABLISH SDEVN(0F60) TDEVN(0F61) SRCEXTNA() andTGTEXTNA()
