Add Counts to Group Header Records

Christopher Horowitz · Posted: Sat Jul 11, 2015 1:21 am

Hi,
I have an 80 byte FB input file that has numerous groups (number of groups varies). Each group has a header and a trailer. I want to put the number of records in each group on the group header record. I've seen it done for a single file header, and I've seen it done for group trailers, but I can't figure out how to do it for group headers.

Input:

As long as your SyncSORT is fairly up-to-date, the same approach should work (even though the JNFnCNTL files may not be documented).

It wasn't recognizing the parameters you specified for JNF1CNTL.

I appreciate very much your responding. I haven't done much in syncsort to this point. Quite an update to my education.

If you can post the full sysout from the failed step, we can see the version you have and what exactly was wrong.

If you don't have access to the JNFnCNTL files, then it is a three-step process. Step1, doing the processing that would be done in JNF1CNTL, Step2 doing the processing that would be done in JNF2CNTL and then Step3 being the JOINKEYS itself.
