#1: IEFUTL4 - wait time limit extended Author: mkusamy,

In one of my job log I could see the below IEFUTL message.

Code:

05.52.21 JOB01866 -JOBNAME STEPNAME PROCSTEP RC I/O CPUTIME ELAPSED
05.52.21 JOB01866 IEFUTL4 - wait time limit extended for #RCM1526 001 TIME
07.00.35 JOB01866 -#RCM1526 RENAME SERV 0 1820 00:00:32.17 02:37:43.80

The procedure SERV use to take few seconds to rename around 600 datasets. But in this case, surprisingly, SERV's Elapsed time is 02:37:43.80 but its CPU time is quiet usual.

Even, if any one of the dataset is being exclusively used (DISP=OLD) by another job/user, SERV will simply print a warning message and will proceed with the next dataset.

So could any one please elaborate the exact meaning of IEFUTL4 and also explain what makes the system to print this message?

Thanks,

When the JOB has been in a WAIT for the limit specified in the SMFPRMxx member in PARMLIB then system exit IEFUTL is invoked. The exit can determine whether the job should get an extension (as yours did) or be terminated.

Perhaps the program was waiting to rename a dataset that was in use?

The step seems to have completed OK anyway (RC=0).

Thanks Dennis.

But, as I already stated

SERV will not wait even if the dataset is already in use.

There might be other causes such as volume "reserves" or catalog contention. No way to tell what caused the wait.
