Abstract: Detection of alteration of storage keys used to protect memory includes determining whether a storage key alteration event has occurred within a processor of a computing environment. The determining includes checking whether one or more selected fields of a storage key have been updated. The storage key is associated with a block of memory and controls access to the block of memory. Based on the checking indicating that the one or more selected fields of the storage key have been updated, a storage key alteration event has been detected. Based on determining the storage key alteration event has occurred, a notification is provided.

Abstract: A memory system is configured for access by a plurality of computer processing units. An address lock bit is configured in a translation table of the memory system. The address lock supports both address lock shared and address lock exclusive functions. A storage manager of an operating system configured to obtain exclusive access to an entry in a DAT table either by obtaining an address space lock exclusive or obtaining an address space lock shared, and setting a lock bit in a DAT entry.

Abstract: A computer system for identifying user managed software modules includes program instructions for: receiving a request for a directed load of a software module into memory, wherein the request includes an address; storing the software module at the address in the received request; adding a name and an address range of the stored software module to a data structure identifying software modules that have been loaded into memory via directed loads; receiving a query that includes an input module name or an input address range; and responsive to determining that the input module name or input address range of the received query is not stored in one or more data structures identifying one or more software modules that have been loaded into memory without directed loads, searching the data structure identifying software modules that have been loaded into memory via directed loads for the respective query.

Abstract: A method for identifying user managed software modules includes: receiving a query that includes an input module name or an input address range. The method further includes, responsive to determining that the input module name or input address range of the received query is not stored in one or more data structures identifying one or more software modules that have been loaded into memory without a directed load, searching a data structure identifying software modules that have been loaded into memory via directed loads for the respective input module name or input address range.

Abstract: Embodiments of the present invention provide methods, program products, and systems for modifying source code by managing symbols indicating executable instructions. Embodiments of the present invention can be used to receive one or more symbols indicating executable instructions to be implemented via source code and generate a visual display comprising a dialog box supporting modification of source code that implements the executable instructions indicated by the one or more symbols. Responsive to receiving a user interaction with the dialog box resulting in modified source code, embodiments of the present invention can be used to generate modified source code or a representation of the modified source code that is shorter than the modified source code.
