Hi,

Is it possible to do a ICETOOL SPLICE without an internal sort?

We are doing some splicing where the files to be spliced are already in the correct sequence for the ON field.

I have noticed that the SPLICE function does an internal sort on the ON field. For some of our larger datasets (10 million + records) this sort must be a significantly overhead in the CPU / I/O cost of the splice?

Thanks

Phil

Phil,

If the records are already in sorted order by the ON field, you can do a COPY instead of a SORT, e.g,.

Code:

//TOOLIN DD *
SPLICE ... USING(CTL1)
//CTL1CNTL DD *
   OPTION COPY
/*
