No, at least not through V6R1. I haven’t checked V7R1 for this.
That is, you can use the CHGOBJAUD command against object QDFTJOBSCD in library QUSRSYS, object type *JOBSCD. Set the object auditing value to *CHANGE.
When system auditing is enabled, a change to the job scheduler will then be logged in QAUDJRN as a normal ZC entry.
The job scheduler requires enough authority that there shouldn’t be many users who can make changes (assuming that authorities are reasonably assigned.) Authorities that allow changes to the job scheduler are sufficient for users to create and schedule their own jobs to do the exact same things.
The job schedule entries can be retrieved/listed with the <a href=”http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=/apis/qwclscde.htm”>List Job Schedule Entries (QWCLSCDE) API</a>. However, creation/change dates are not tracked in the schedule object. There’s no point to doing it since standard object auditing can cover it.
It does seem a little odd that it’s not included in the *SYSMGT area of system auditing. I would recommend asking IBM to cover it.
