Hi Sriram,
1] Parameters are as per the recommendation and our current requirement. We have not faced any issue in that Regards.
2] Everything is fine, but sometimes when the Extended Memory is near to exhaust or exhausted due to Background Job using it in huge amount of Extended Memory without using the Heap Allocated creates High CPU Loads, Response Time Shoots up.
3] Even though we use Z program am not sure how can it use Extended Memory.
