If you mean in relation to the private area? Any virtual storage report or display will tell you.
How it works: The line between Common and Private is on MB boundary. Common is LPA+SQA+CSA, rounded to 1 MB. What is left is Private. CSA is here defined in IEASYSxx as 3300K. This is the minimum of CSA that will be created after SQA and LPA and rounded to the next MB. In this example, it turns out to be 4000K (X'CE7FFF'-X'900000'). So I can raise CSA in IEASYSxx until 4000K and nothing will change. If I raise it above 4000K, another MB must be taken to satisfy the request and the private area will be decreased by 1 MB. I can lower CSA in IEASYSxx to (approx.) 3000K and nothing will change. If I lower it below (approx.) 1000K, 1 MB less will be neede to satisfy the request and private area will grow by 1MB. If you want to increase the private area, you must check the usage of CSA and SQA and calculate how must you can/must decrease them to make the line between Private and Common jump 1 MB up. Kees.
