One of our Z-transactions (run in background) terminates with the runtime error TSV_TNEW_PAGE_ALLOC_FAILED. It runs successfully in another system. Of course memory settings are different in these systems so are the resources. I see in the affected system that parameter abap/heap_area_total is 2GB and parameters abap/heap_area_dia and abap/heap_area_nondia are only allocated 10MB each. Will there be any issue if we increase the above 2 parameters to 2GB each? If we do so, is the value allocated entirely at startup? Will it affect system performance? Please help.
