Systems and methods for managing memory in a dynamic translation computer system are provided. Embodiments may include receiving an instruction packet and processing the instruction packet. The instruction packet may include one or more instructions for obtaining a block of virtual memory for use in an emulated operating environment from a slab of virtual memory in a host environment, maintaining a mapping between the block of virtual memory and physical memory when the block is returned to the host environment, and for filling the block of virtual memory with zeros and a pattern based, at least in part, on a detected fill type.

Systems and methods for memory management in a dynamic translation computer system

A computer system is described for representing and enforcing configuration rules that can be used to create and define a configuration or hardware definition for the computer system. The computer system represents configuration rules that define a configuration of a high end mainframe, such as an OS2200 system, in a file external to a configuration program with which a user may interact to manage the configuration of the mainframe system, and to enforce the configuration rules as a user is attempting to modify a configuration of a computer system. The configuration rules may be specified in, for example, an extensible markup language (XML) file format rather than in the source code of the executable program. The external configuration file may conform to a scripting language that allows a developer to embed validation operations for the configuration data specified in the XML file.

Real-time management of a configuration of a computer system

A method and apparatus for managing the configuration of a computing arrangement having a host operating system and an emulator operating system includes establishing host operating system interfaces to computing arrangement components. The computing arrangement is scanned, using the host operating system interfaces, to determine configuration information about computing arrangement components reserved for use by the emulator operating system. At least a portion of the scanned configuration information is communicated to the emulator operating system.
