WARP086I: DATE SIMULATOR NOT STARTED. PC# INCORRECT. CHECK FOR CONFLICTING PRODUCTS
If there is any date products already in the system them the product will not initialize.
No way around this, no special option available.
Here is a basic summary of what DateSim does with the SVC:
DateSim is started as an MVS subsystem. The user instructs DateSim to temporarily alter the start date (/time) of a particular job, started task, or TSO user. When DateSim is turned off, the hooks that were inserted into MVS to handle the TIME macro (SVC 11 and the IEATTIME Program Call routine) are removed. However, the hooks necessary for trapping Store Clock instructions, i.e. the program fetch routine and the first level SVC interrupt handler, must be left in and will remain until the next IPL. If DateSim is restarted, these hooks are reused. Of course, when DateSim is turned off, these hooks take the appropriate action; that is, they let the call go through to the system routine since, with DateSim off, no jobs are under its control.
