Hi
i use this util to compare two Fb file .
why when detect a difference give different rows number logicl/physical etcc?

Code:
IEB221I    RECORDS ARE NOT EQUAL
     DDNAME = SYSUT1
     PHYSICAL RECORD NUMBER = 00002798  LOGICAL RECORD NUMBER WITHIN PHYSICAL RECORD = 00000057
00001CF0F0F0F0F0F0F0F0F0F0F2F3F3F9F4F9C9E3D2F0F5F0F8F8F2F5F64040404040404040404040404040000000000C404040019930921C000000
000C019930921C0160457000000CF000001CF0F0F2F3F34040D4C9C7D9F2F0F0F160F0F9F2F8
     DDNAME = SYSUT2
     PHYSICAL RECORD NUMBER = 00000520  LOGICAL RECORD NUMBER WITHIN PHYSICAL RECORD = 00000125
00001CF0F0F0F0F0F0F0F0F0F0F2F3F3F9F4F9C9E3D2F0F5F0F8F8F2F5F24040404040404040404040404040000000000C404040019930921C000000
000C019930921C0160457000000CF000001CF0F0F2F3F34040D4C9C7D9F2F0F0F160F0F9F2F8

Can you show the block size for each file ?

IBM recommends using the SuperC utility instead of IEBCOMPR

Bullthis! With SuperC you get well annotated output and not the AD 1970 crap above.

Suggestion? Add
Code:
 worksize 524288

to your SuperC control statements. And run SuperC in batch!

Different block sizes is the reason you see different physical and logical positions in your comparison.

Change block size using SORT COPY to match other file creating a temp dataset and then run match using the same block size datasets.

That is a workaround. Not sure what else is available in IEBCOMPR.

Is SUPERC suggestion by Prino not doable?


What's next once you detect mismatches? Finding reason for mismatched data by looking through the hex results is tedious if there are many mismatches.

//NEWDD DD DSN=xxxxxx.xx.xxx.,DISP=SHR     
//OLDDD DD DSN=xx.xxx.xxx.xxxxx,DISP=SHR     
//OUTDD DD DSN=xxxxxx.xx.xx.TEMP.COMPARE,                 
//         DISP=(NEW,CATLG,CATLG),                             
//         DCB=SYS2.FB,SPACE=(CYL,(60,60),RLSE)                 
//SYSIN  DD *                                                   
WORKSIZE 524288                                                 
//*
