Stacking output image copies

Places two or more image copy data sets on the same tape or on a set of tapes (stacking) to increase the tape media efficiency.

You can request stacked output by specifying the STACK keyword in either of the following formats in the ICEIN control statement.
  • STACK=ddname
  • or
  • STACK=(ddname1,ddname2)
For example, if you specify the following control statements, the output image copy data sets from database data set groups DBDSA, DBDSB, and DBDSC are stacked into one set of tapes having the volume serial numbers VOL001, VOL002, and VOL003, respectively.
   GLOBAL VOLSER=(VOL001,VOL002,VOL003)
   IC DBD=SAMPDBD,DDN=DBDSA,STACK=STACK1
   IC DBD=SAMPDBD,DDN=DBDSB,STACK=STACK1
   IC DBD=SAMPDBD,DDN=DBDSC,STACK=STACK1
