Re: "Sort Capacity Exceeded" thought / question
John, The answer is that it's a little of both... "technical reason" and "we didn't think of it". We are looking at ways to improve our dynamic allocation of work data sets to provide some additional flexibility. So it is on our list of things we'd like to improve on.

Re: "Sort Capacity Exceeded" thought / question
I don't know about DFSORT but SYNCSORT has another parm for dynamic allocation besides regular work "McKown, John" To Sent by: IBM IBM-MAIN@bama.ua.edu Mainframe cc Discussion List "Sort Capacity Exceeded" thought / question 12/21/2009 01:30 PM Please respond to IBM Mainframe Discussion List Due to a mistake in JCL, one of our batch jobs got a "Sort Capacity Exceeded" message in DF/SORT on z/OS 1.10. So, I was just wondering about something. When this happens, why can't SORT just allocate another SORTWKnn DD and continue? I know that there is an upper limit on this, but then I got to wondering why SORT cannot simply reallocate an existing SORTWKnn? I guess it would need to copy the current contents to some other dynamically allocated DD, then reallocate and recopy the contents back in. Granted, the overhead on this would be large, but I would prefer it to abending a 4 hour sort. Especially if it were updating a non-recoverable resource, such as a VSAM file. Perhaps a required non-standard option in DFSPARM, as opposed to being able to specify it in the ICEMAC parm or dynamic PARMLIB parm?

But this is in an ICEAM2 environment (internal sort). Apparently the application does not pass an accurate count to SORT. And, from what I can see, it does multiple internal sorts. I did state a JCL error, but the error was not having an SORTWKnn statements in the JCL at all. But that is not the prime reason for my inquiry. I am just curious if this facility is not in sort for a technical reason, a business reason, or a "we didn't think of that" reason.

Re: "Sort Capacity Exceeded" thought / question
John, What is your current parameter for dynamic SortWKxx set at? Maybe you just need to increase that number? Or if you have one-off types, provide them with the SORT Over ride that could let them allow for more dynamically allocated sortwk.
