Is there any option or command (built in) in SORT to get this info in the spool as a separate sysout?

File1 records read count
File2 records read count
Matched records read count
Unmatched record count only in file1
Unmatched record count only in file2
Number of records written in o/p file.

Tried to find this in manual/web, but no luck...

Do you mean that you have a need of these figures for a particular requirement, or in general?

What are "Matched records read"?

I need it just as a statistics in the spool, in case if business asks for todays stats.

"Matched records read" is a typo. Its "Matched records count".

You can get counts in your Sysout. Can you post a sample of your sysout from a Joinkeys application.

We are glad you weren't able to attach. Attachments tend to be frowned-upon.

Paste and in the Code tags is how we like them. Thank you.
Code:

Firstly, I may have appeared too "literal". When I said "sysout" I meant "sysout=whatever", not just the SYSOUT DD. You have counts of the two input files in your other two message datasets.

The thing then is, how do you break-down the "joined" count. I'm not sure (but I will be corrected) if this can be done in a "useful" manner by default, the reason being the potential, as far as JOINKEYS is concerned, for duplicates on either, or both, input files.

So, if you want a breakdown of the joined data, you have to do it yourself, with knowledge of your data.

While we are here:

Is your output going to tape?

Your sort cards could benefit from a bit of rationalisation.

Thats what I was looking for, some inbuilt feature or option in sort.
I know, we can get i/p file record count in the JNF1JMSG and JNF2JMSG, but not the matched and o/p file write count.

No, the output is not going to tape, can still it be benefitted with rationalisation?

Yes, the two things are not connected.

Your output seems, then, to have its own blocksize specified. 32,000 for a 3390 disk is not good, as it will leave a huge lump of each track empty. Either let DFSORT do the blocksize (best) or calculate a good blocksize manually.

The rationalisation of the sort cards revolves around the presence or otherwise of an actual match. The key from file 2 you do not need on the reformat record: it is either not present, or it is the same as on the F1. You test a flag extracted from F2, which only makes sense for a B, yet you also test for 1. The results will be the same, but things are confusing to the reader.

If you want some review of the cards, please provide the business description of the process (not just write down what the current cards are doing).

Back to your original question, input to the sub-task, input to the main task, output from the main task, including OUTFIL processing, all of those you have.

The breakdown of the matching process, you'd have to do yourself, I think.

Can there be duplicates on either input dataset?

Code:
  OUTFIL FILES=F1,INCLUDE=(12,1,CH,EQ,C'1'),
         BUILD=(1,1),
         REMOVECC,NODETAIL

OUTREC BUILD=(1,700) 


You can try something like this to get you going.

You'll need SORTOFF1 in your JCL, I'd make it a DUMMY as nothing should get on to it.

The idea is to include all the the "1" values from the join marker, but then, with NODETAIL, to remove them from the output dataset. You will see the count for these in the SYSOUT dataset. You should then have the information you need to know all the figures, I think.

EDIT: Forgot to say, check back later/tomorrow for the best answers/solution from San Jose.

This will only work when there are no duplicates in either file.

Also I've used two 80 byte files as input and the key is 1 byte in pos 1.

@Bill, Gerry: Thanks a ton for the solutions provided.

San Jose / anyone from DFSORT team, is there any other solution?
Is there any built-in function in SORT available?

Well, as they say - there are lies, damn lies and statistics.

I'm not sure what statistics exactly you're looking for or whether they make sense for every type of JOINKEYS operation (e.g. cartesian join).

Please show an example of the records in your input files for the cases you are interested in (dups in file1? dups in file2?) and show what you would expect the statistics to show (the actual numbers for your input examples). That might help you to figure out if what you want is actually meaningful. It would certainly help me figure out what you're trying to do exactly.

Frank,
Thanks for the reply.

Let me give you some background. There are few old COBOL programs witch are doing file matching logic on very huge files, and consuming lots of CPU. So to reduce the CPU usage, I am trying to incarporate same logic in JOINKEY.
Now, cobol has displays of stats in SYSOUT and that is the reason I am looking for same in SORT.

Input & output files are FB.
There are no duplicates in both the files.
Number of records are around 5 million.
LRECL are as follows:
I/P 1- 700
I/P 2 - 200
O/P - 700 (same as I/P)

Sort Card:
Code:

JOINKEYS FILE=F1,FIELDS=(1,6,A),SORTED,NOSEQCK                       
JOINKEYS FILE=F2,FIELDS=(176,6,A),SORTED,NOSEQCK                     
JOIN UNPAIRED,F1                                                     
REFORMAT FIELDS=(F1:1,700,F2:176,6,21,1,91,14,?)                     
OPTION COPY                                                         
      INREC IFTHEN=(WHEN=(722,1,CH,EQ,C'B'),                         
                    OVERLAY=(524:708,14,ZD,MUL,+100,TO=PD,LENGTH=8),
                    HIT=NEXT),                                       
            IFTHEN=(WHEN=(722,1,CH,EQ,C'1'),                         
                    OVERLAY=(524:X'000000000000000C'),               
                    HIT=NEXT),                                       
            IFTHEN=(WHEN=((707,1,CH,EQ,C'Y',AND,722,1,CH,EQ,C'B'),   
                          OR,722,1,CH,EQ,C'1'),                     
                    OVERLAY=(532:X'000000000000000C'),               
                    HIT=NEXT),                                       
            IFTHEN=(WHEN=(707,1,CH,NE,C'Y',AND,722,1,CH,EQ,C'B'),   
                    OVERLAY=(532:708,14,ZD,MUL,+100,TO=PD,LENGTH=8))
      OUTREC BUILD=(1,700)                                           


My requirement is to get below stats in sysout:

File1 records read count -
File2 records read count -
Matched records count -
Unmatched record count only in file1 -
Unmatched record count only in file2 -
Number of records written in o/p file -

Use the following DFSORT JCL which will give you the desired results

Code:

//STEP0100 EXEC PGM=SORT                                       
//SYSOUT   DD SYSOUT=*                                         
//INA      DD DSN=Your Input File1,DISP=SHR
//INB      DD DSN=Your Input File2,DISP=SHR
//SORTOUT  DD SYSOUT=*                                         
//RPT      DD SYSOUT=*                                         
//SYSIN    DD *                                               
  OPTION COPY

            'UNMATCHED RECORD COUNT ONLY IN FILE2  : ',           
            TOT=(717,1,ZD,M11,LENGTH=8),/,                       
            'NUMBER OF RECORDS WRITTEN IN O/P FILE : ',           
            TOT=(712,1,ZD,M11,LENGTH=8))                         
//*
//JNF2CNTL DD *                                                   
  INREC BUILD=(176,6,91,14,ZD,MUL,+100,PD,LENGTH=8,21,1)

The statistics are written to the RPT DD
