If JES2 is started before OPS, then code IPL_STATE of IPL in your STCTBL.
If OPS starts/controls JES2 then code IPL_STATE of UP in your STCTBL.
Refer to the SSM User Guide page 236:
Step B: Review and Customize the STCTBL Table 6. Supply the correct IPL_STATE value that will tell SSM how this task should be handled after an IPL. The IPL_STATE column initiates the DESIRED_STATE column after an IPL. Valid values for the IPL_STATE column are:
UP = SSM should start the task at IPL.
DOWN = SSM should not start the task at IPL.
IPL = Something outside of SSM will start the resource, but SSM should manage it after it becomes active.
