How do I get step condition codes to print in the JES2 job log

Install the SMF exit IEFACTRT. The source is in SYS1.SAMPLIB(IEEACTRT).

1. Run this job to install the exit in a linklist library:

//SPSMFXIT JOB CLASS=A,MSGCLASS=X,MSGLEVEL=(1,1),NOTIFY=&SYSUID
//ASMXIT EXEC HLASMCL,REGION=4M,COND.L=(0,NE,C),
// PARM.L='LIST,LET,NCAL,XREF,RENT,REUS'
//C.SYSLIB DD DSN=SYS1.MACLIB,DISP=SHR
// DD DSN=SYS1.MODGEN,DISP=SHR
//C.SYSIN DD DSN=SYS1.SAMPLIB(IEEACTRT),DISP=SHR
//L.SYSLMOD DD DSN=USER.LINKLIB(IEFACTRT),DISP=SHR,UNIT=,SPACE=

2. Update your SMF parameter member SMFPRM00 in USER.PARMLIB. You need SMF recording ACTIVE, you need to record at least type 30 records which drive the IEFACTRT exit, and of course you need to specify that exit IEFACTRT is active. Here is an example SMFPRM00 member:

ACTIVE /* ACTIVE SMF RECORDING */
DSNAME(SYS1.MAN1,
SYS1.MAN2,
SYS1.MAN3)
NOPROMPT /* DO NOT PROMPT OPERATOR */
REC(PERM) /* TYPE 17 PERM RECORDS ONLY */
MAXDORM(3000) /* WRITE IDLE BUFFER AFTER 30 MIN */
STATUS(010000) /* WRITE SMF STATS AFTER 1 HOUR */
JWT(2400) /* 522 AFTER 24 HOURS */
SID(&SYSNAME(1:4)) /* USE SYSTEM NAME FROM IEASYM00 */
LISTDSN /* LIST DATA SET STATUS AT IPL */
SYS(TYPE(14:19,30,62:69),NOEXITS,NOINTERVAL,NODETAIL)
/* WRITE ONLY DATA MANAGEMENT RECORDS, TAKE NO EXITS. */
/* NOTE: JES EXITS CONTROLED BY JES , THERE IS NO */
/* DEFAULT INTERVAL RECORDS WRITTEN AND ONLY SUMMARY T32 */
/* RECORDS AS A DEFAULT FOR TSO. */
SUBSYS(JES2,EXITS(IEFACTRT))
/* WRITE RECORDS ACCORDING TO SYS VALUE, TAKE ONLY IEFACTRT EXIT. */
/* USE ALL OTHER SYS PARMETERS AS A DEFAULT. */

3. Enter this MVS command to activate the updated SMF parameters:

SET SMF=00

4. Enter these MVS commands to activate the exit:

F LLA,REFRESH
SETPROG EXIT,DELETE,EXITNAME=SYSJES2.IEFACTRT,MODNAME=IEFACTRT
SETPROG EXIT,ADD,EX=SYSJES2.IEFACTRT,MOD=IEFACTRT,DSN=USER.LINKLIB
