hi all,
I have two files each with million of records.
Need to match the record field from file1 with file2 record fields. if duplicated are found the the duplicate record is to be written into file3.
Please let me know the solution for this.
Please note : the file is a flat PS file. |

Hi,
are there duplicates in either file ?
What constitues a duplicate, do both files have the same layout ?
Please provide data from both files and what is expected in file 3

You haven't given enough information for anyone to do that.
Please show an example of the records in each input file (relevant fields only) and what you expect for output. Explain the "rules" for getting from input to output. Give the starting position, length and format of each relevant field. Give the RECFM and LRECL of the input files. If file1 can have duplicates within it, show that in your example. If file2 can have duplicates within it, show that in your example.
Also, run this job and show the //SYSOUT messages you receive, so I can see what level you're at:
| Code: |
//S1 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD *
RECORD
//SORTOUT DD DUMMY
//SYSIN DD *
OPTION COPY
/*

suppose lerecl are fixed to 80 chars for both the files and we have only one field called R1 in file1 and R2 in file2
R1 and R2 both are of lenght 10 aplphanumeric items starting fropm position one. both R1 and R2 have duplicate values.
Need to find record which is present in R1 and R2 both.
It can be achieved using icetool i heard. Please let me know the solution.
Let me know if more info is required. |

It would really have helped if you'd given all of the information I asked for including an example of input and output. Since you didn't, I can only guess what your files look like.

Assuming you mean that there are dups within file1, and dups within file2, you can use a DFSORT/ICETOOL job like the following (of course, I don't know if your files really look like this but it should give you the idea):
| Code: |
//S1 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//IN1 DD *
AAAAAAAAAA FILE1 R1
AAAAAAAAAA FILE1 R2
CCCCCCCCCC FILE1 R3
BBBBBBBBBB FILE1 R4
BBBBBBBBBB FILE1 R5
BBBBBBBBBB FILE1 R6
FFFFFFFFFF FILE1 R7
FFFFFFFFFF FILE1 R8
/*
//IN2 DD *
AAAAAAAAAA FILE2 R1
DDDDDDDDDD FILE2 R2
CCCCCCCCCC FILE2 R3
CCCCCCCCCC FILE2 R4
FFFFFFFFFF FILE2 R5
FFFFFFFFFF FILE2 R6
/*
//T1 DD DSN=&&T1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(MOD,PASS)
//OUT DD SYSOUT=*
//TOOLIN DD *
SELECT FROM(IN1) TO(T1) ON(1,10,CH) FIRST
SELECT FROM(IN2) TO(T1) ON(1,10,CH) FIRST
SELECT FROM(T1) TO(OUT) ON(1,10,CH) FIRSTDUP
/*
|
For this example, OUT would have:
| Code: |
AAAAAAAAAA FILE1 R1
CCCCCCCCCC FILE1 R3
FFFFFFFFFF FILE1 R7
