How is it possible to do a cross-sysplex copy of a PDS dataset by running one JCL on the target sysplex? I tried to use IEBCOPY with SUBSYS & CSM as follows: //CSMTRAN1 EXEC PGM=IEBCOPY //SYSPRINT DD SYSOUT=* //SYSUT1 DD DSN=PDS-Dataset-name-from,DISP=SHR, // SUBSYS=(CSM,'SYSPLEXNAME-FROM') //SYSUT2 DD DSN=PDS-Dataset-name-to,DISP=OLD, // SUBSYS=(CSM,SYSPLEXNAME-TO') //SYSIN DD DUMMY This did not work.
