When running SARINIT to update the View initialization parameters, do the options from that SARINIT job take effect immediately or when the View started task is recycled?
When the View SARINIT parameter change takes effect will depend on what parameters were changed.
Some changes require a recycle of the SARSTC to take effect. Some require that the users just logoff and then back on again. And some changes take effect immediately without any additional action.
The requirement for each of the SARINIT parameters is documented in the section entitled "Activate and Modify" here
