Abstract
In a computing system having swappable and non-swappable address spaces, wherein the computing system includes an operating system that includes a Real Storage Manager (RSM), a Systems Resource Manager (SRM) and a Region Control Task (RCT), a method for recovering swappable fixed non-preferred memory is provided which includes receiving a request from the operating system to configure an area of real memory to create an intercepted swappable address space, wherein the intercepted swappable address space includes a flagged fixed frame element identified for configuration, examining the intercepted swappable address space so as to determine if the intercepted swappable address space will remain swappable, requesting the SRM to coordinate the swapping process, quiescing the intercepted address space, generating a first return code responsive to the intercepted swappable address space remaining swappable, communicating the first return code to the RCT so as to cause the RCT to respond to the first return code, instructing the RSM to proceed based on the first return code, examining the intercepted swappable address space so as to identify the flagged frame elements, exchanging the flag…
