Question:

Is there an IDMS report I can run to determine the I/O on a local mode job?

Environment:

z/OS

Answer:

You can add the parameter BUFFERSTAT to the SYSIDMS file and make sure a SYSLST DD statement is present in the JCL.
You can also look at the I/O counts by device in the jobs JCL output listing but that will not differentiate 
between read and write I/Os. The IDMS numbers are not maintained past the completion of the jobstep for a local job. 

The JES listing for the job contains CPU and EXCP numbers. 

For example:

10.57.59 JOB14947 CAJR250I STEPNAME STEP PGM= CCODE EST-COST EXCPS
10.57.59 JOB14947 CAJR251I IDMSBCF 1 IDMSBCF 0000 $4.08 725 
10.57.59 JOB14947 IEF404I BRE$5784 - ENDED - TIME=10.57.59
