ask Your peers or your organization to provide You the IAMUTIL manuals and search for the meaning
of the U302 abend code..

IAMUTIL is not a program generally used, so the manuals are not readily available to everybody.

asking Your peers will be the fatsest solution.

U... are user abend codes and are program dependent

Hi,
Quote:
what is IAMUTIL

IAMUTIL is a tool which can be used to backup and recover IAM files.

Here is one example which I got: The following sample JCL dumps the IAM file named CC.TEST.IAM to a sequential tape backup GDG named CC.TEST.BACKUP.IAM.

Code:
//CCDUMP JOB (CC,00),CC,MSGCLASS=A,CLASS=N
/*ROUTE PRINT CC
//STEP1 EXEC PGM=IAMUTIL
//SYSPRINT DD SYSOUT=A
//SYSUDUMP DD SYSOUT=A
//DISKIN DD DSN=CC.TEST.IAM,DISP=OLD
//TAPE1 DD DSN=CC.TEST.BACKUP.IAM(+1),UNIT=TAPE,
// DISP=(,CATLG,DELETE),DCB=(CC.GDG----)
//SYSIN DD *
DUMP
/*


By the way, when you say "what is IAMUTIL" sounds strange to me - you are uisng it & you don't know what is this used for ?.. icon_confused.gif ..

From manuals

U302
The I/O measurement routine experienced an excessive number of failures when looking up data set names. Check either the system dump data sets for a dump entitled, "CA-ASTEX - DSN LOOKUP FAILED," or the logrec for S0C4 abend entries for CA-ASTEX.


If you need a better solution - please post the complete diagnostic information from the abended JOB.
