A server system may be configured to access a first contiguous portion of memory for a first activity of a plurality of activities, and to transfer data associated with the first activity into the first contiguous portion of memory. The first contiguous portion of memory may be placed in a memory repository to make the first contiguous portion of memory available for access by at least a second activity of the plurality of activities, and an identifier may be assigned to the first contiguous portion of memory placed in the memory repository. The server system may also be configured to access the first contiguous portion of memory for the second activity, and to transfer the data associated with the first activity from the first contiguous portion of memory to memory specifically associated with the second activity.

Enhanced message control banks

A non-stop multi-host transaction processing environment may be created by receiving incoming user calls to components through a vestibule bank, and by utilizing an installation manager during the replacement of software. The installation manager may be used in connection with a vestibule bank to handle user calls during the installation of a replacement software component such that user calls for a component can be processed while that component is being replaced, without an error being passed back to the end user. During the replacement of a software component, user calls from the old component may be drained and diverted to a replacement component. User calls received during the installation may be queued and then routed to the replacement component once the component has been replaced.

Dynamic replacement of software components

Systems and methods for clearing bank descriptors for reuse by gate banks without requiring a system reboot are described. In some embodiments, information regarding a bank descriptor of a memory system may be obtained. From the information, a determination may be made as to whether the bank descriptor describes a common bank. When the bank descriptor describes a common bank, the bank descriptor can be updated to no longer describe the common bank.
