Hi,

I have two files.

One is DASD FB LRECL=80 having 2 million records and other one is VB 3746 Tape file having around 50 million records.

The key in first file is from position 1 - 9 bytes and the key in second file is from 1448 (including the 4 bytes for VB) - 9 bytes length.

I need the output file to having the matching records from second file.

Can anyone give me the syntax for this?

Also, will Syncsort work efficiently for this in terms of performance?

We have a cobol in place for this, but it is taking 8 hours to find the matching records and do the rest of program processing.

Can we reduce the run time in any way?

Thanks in advance.

Sivaraj,

Assuming all the records in the Tape File have a length of at least 1456, then try the following SyncSort application:
Code:
//STEP1  EXEC PGM=SORT,PARM='ELAP'
//SYSOUT   DD SYSOUT=*
//SORTJNF1 DD DSN=TAPE.INPUT.VB3746
//SORTJNF2 DD DSN=DASD.INPUT.FB80
//SORTOUT  DD DSN=MATCH.F1
//SYSIN    DD *                     
   JOINKEYS FILE=F1,FIELDS=(1448,9,A) 
   JOINKEYS FILE=F2,FIELDS=(1,9,A) 
   REFORMAT FIELDS=(F1:1,4,5)
   SORT FIELDS=COPY
