Issue/Introduction

Running an IDMS CV with SYSIDMS parm DATE_SIMULATOR_SVC=nnn to enable a date simulator product will cause S0F8 and U3964 abend if running zIIP=Y.

Environment

Release: All supported releases.

Cause

To run Date Simulator products in an IDMS CV, the SYSIDMS parameter DATE_SIMULATOR_SVC=nnn must be used. This tells IDMS that in all places where the system code would have issued a STCKE instruction, it will instead issue the DateSim SVC which will return the STCKE format time required.

This means that it is incompatible with zIIP and CV will abend with S0F8 and U3964.

Resolution

Date Simulator products cannot be used in an IDMS CV with zIIP=Y.
