Hi, We run z/os 1.13 with ca-sort 7.1 (a Computer Associates product). This sort software is discontinued since January 30, 2012 and I’m trying to evaluate the project of migration to dfsort in order to be full compatible and supported when z/os 2.1 will come. Before starting migration, I should be happy finding some document or experience about compatibility between these two sort softwares (supported files, sort functions and parameters, default sort options) in order to help me answer such questions: - Are there parameters wrotten differently ? - Are there some ca-sort parameter which has no equivalent in dfsort ? - how long migration can spend ? Ibm support could not help me in this task. This IBM-MAIN Forum topic "Has anyone replaced ca-sort with ibm sort recently? any issues?" says it is not very difficult without bringing more information. We use ca-sort in a basic way : - Svc 17 esr loaded at ipl time - a module defining default sort options - 4000 batch sort steps o //STEP030 EXEC PGM=SORT o //SORTIN DD DSN=FPAIMA.AIMA864A,DISP=SHR o //SORTOUT DD DSN=FPAIMA.AIMA864A,DISP=SHR o //SORTWK01 DD UNIT=SYSWK,SPACE=(CYL,(25,1),RLSE) o //SORTWK02 DD UNIT=SYSWK,SPACE=(CYL,(25,1),RLSE) o //SORTWK03 DD UNIT=SYSWK,SPACE=(CYL,(25,1),RLSE) o //SYSOUT DD SYSOUT=* o //SYSIN DD * o SORT FIELDS=(1,38,A),FORMAT=CH - SUM FIELDS=NONE o /* - Sort modules are in linklist - Of course above sysin changes according to application’s need - We don’t use sort exits and very few sorts are invoked by programs rather than by JCLs Regards Denis
