I have a step in JCL one which uses SORT. Now, I have someone telling me ICEMAN is better in terms of performance which I dont really believe in.

As far as I know, SORT may internally decide to call ICEMAN if it finds need for that.

Below are the steps.

//SORT01 EXEC PGM=ICEMAN

//SORT01 EXEC PGM=SORT

Can someone confirm this?


If ICEMAN is same as SORT,do we have manual link which says they both are same?

OR

If ICEMAN is better, what are the parameters which makes it better?

Thanks,

rajen,

ICEMAN, SORT are two of the program aliases that can be used to invoke the sort product.ICEMAN is the program name for DFSORT. You can invoke DFSORT with PGM=ICEMAN. DFSORT is also shipped with an alias of SORT, so you can use PGM=SORT

DFSORT's official three-character identifier is ICE, so all of the DFSORT modules start with ICE (ICEMAN, ICETOOL, ICEGENER, etc) and all of the DFSORT messages start with ICE (ICExxxs).

other sort products(Syncsort, ca-sort) use (SORT,ICEMAN) as an alias. So when you use PGM=SORT or PGM=ICEMAN, you'll get the sort product installed at your site.

Hope this helps...

Thanks for the prompt reply.

I just wanted to confirm my doubt. I had someone telling me that ICEMAN is performance wise better than SORT and I should change my proc to point to PGM=ICEMAN than PGM=SORT. I was having impression that It doesn't really matter since they both use DFSORT.

Do we have manual link which would confirm whatever you said? Although, I do know that whatever u say is MANUAL

PGM=ICEMAN and PGM=SORT are equivalent.

This is documented in Chapter 2 of "z/OS DFSORT Application Programming Guide". Specifically here:

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/ICE1CA20/2.3?DT=20060615185603

Note that the syntax shows PGM=SORT and PGM=ICEMAN as equivalent and later it says:

You can check whether the modules are the same at your site (they're probably in the linklist or LPA):

1. In ISPF option 6 enter ISRDDN LINKLIST
2. now enter MEMBER ICEMAN to locate the module
3. note the module size and location
4. now enter MEMBER SORT to locate this module
5. compare the results (it may even say "alias of ICEMAN")

Frank,
Thanks for reply. No I did check all the default version and setting which usually gets shipped with DFSORT and it doesnt seem like they have changed.

I did test using PGM=ICEMAN and PGM=SORT, but none is ready to believe.

Now, I have a manual link. Hope this time someone might!!!

Thanks again.

Hey Bill,
I does say ALIAS OF ICEMAN.


I never knew this way to check data.

Thanks for the info.
