Replying to a message from a few weeks ago; something just made me thing of it again. What are the "performance implications" that you refer to here? And what is your recommended alternative? A STEPLIB for every job step?
I just read something interesting: http://publib.boulder.ibm.com/infocenter/zos/basics/index.jsp?topic=/com.ibm.zos.zjcl/zjclc_jclEXECsearch.htm "For a multi-step job, using the JOBLIB DD statement is most efficient when most of the programs reside in private libraries. For a multi-step job, using the STEPLIB DD statement is most efficient when most of the programs reside in system, rather than private, libraries."
