Abstract

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.

Claims

1. A method of configuration management for a computing arrangement having a host operating system and an emulator operating system, comprising:

establishing host operating system interfaces to computing arrangement components;

scanning the computing arrangement to determine configuration information about computing arrangement components reserved for use by the emulator operating system using the host operating system interfaces;

communicating the scanned configuration information to the emulator operating system; and

configuring the emulator operating system using the communicated configuration information.

2. The method of claim 1, further comprising generating a data structure responsive to the scanning, the data structure comprising the scanned configuration information.

3. The method of claim 2, further comprising modifying the data structure through a user interface prior to communicating.

4. The method of claim 2, further comprising approving the data structure through a user interface prior to communicating.

5. The method of claim 1, wherein the host operating system comprises a Windows operating system, the emulator operating system comprises a mainframe operating system, scanning occurs during a boot process of the host operating system, and communication of the at least a portion of the scanned configuration information occurs during a boot process of the emulator operating system.

6. A method of configuration management for a computing arrangement having a host operating system, comprising:

executing an emulator on the host operating system;

executing an emulator operating system on the emulator;

scanning the computing arrangement using host operating system interfaces;

identifying at least one computing arrangement component reserved for use by the emulator, and the configuration thereof, in response to the scanning;

compiling a data structure representative of the configuration in response to the identifying;

communicating the configuration to the emulator operating system; and

configuring the emulator operating system using the communicated configuration information.

7. The method of claim 6, wherein communication of the configuration occurs during the emulator operating system'"'"'s boot process.

8. The method of claim 7, further comprising building a file representative of the data structure.

9. The method of claim 8, wherein the file comprises a Partition Data Bank (PDB) file representative of at least some components and connections of the computing arrangement.

10. The method of claim 6, wherein the steps of executing, scanning, identifying and compiling are automatically performed.

11. The method of claim 6, further comprising modifying the data structure through a user interface.

12. The method of claim 11, wherein modifying the data structure through a user interface occurs prior to communicating the configuration to the emulator operating system.

13. The method of claim 6, further comprising approving the data structure through a user interface prior to communicating.

14. The method of claim 6, wherein the host operating system comprises a Windows operating system.

15. The method of claim 6, wherein scanning occurs dynamically during a boot process of the host operating system.

16. The method of claim 6, wherein the host system operating interfaces comprise software interfaces.

17. The method of claim 6, wherein the emulator emulates a mainframe instruction set.

18. The method of claim 17, wherein the emulator operating system comprises a Unisys OS 2200 operating system.

19. The method of claim 6, wherein the at least one computing arrangement component is selected from a group comprising Input/Output Processors, Small Computer Systems Interface (SCSI) channels, control units, and devices.

20. A computing arrangement having a host operating system, comprising:

means for executing an emulator on the host operating system;

means for executing an emulator operating system on the emulator;

means for scanning the computing arrangement using host operating system interfaces;

means for identifying at least one computing arrangement component reserved for use by the emulator, and the configuration thereof, in response to the scanning;

means for compiling a data structure representative of the configuration in response to the identifying;

means for communicating the configuration to the emulator operating system; and

means for managing the configuration of the emulator operating system using the communicated configuration.

21. A computing arrangement having a host operating system, comprising:

an emulator executing on the host operating system;

an emulator operating system executing on the emulator;

host operating system interfaces adapted to scan the computing arrangement;

software adapted to identify at least one computing arrangement component reserved for use by the emulator, and the configuration thereof, in response to the scanning;

an application adapted to compile a data structure representative of the configuration in response to the identifying; and

a file arranged to communicate the configuration to the emulator operating system which is configured using the communicated configuration.

22. A computing arrangement having a first operating system, comprising:

a central processor programmed and configured to emulate a second computing arrangement, the emulated second computing arrangement being operable on the first operating system, and having an emulator operating system;

at least one computing arrangement component communicatively coupled to the central processor, the at least one computing arrangement component being reserved for use by the emulator operating system and scanned through first operating system interfaces; and

a Partition Data Bank (PDB) builder module programmed and configured to ascertain configuration information of the emulated second computing arrangement responsive to the scanning, and to assemble and communicate the configuration information to the emulator operating system which is configured using the communicated configuration information.

23. The computing arrangement of claim 22, wherein the PDB builder module comprises a processor programmed and configured to identify the configuration of the at least one computing arrangement component, to compile a data structure comprising scanned configuration information representative of the emulated second computing arrangement, and package a portion of said configuration information in a file arrangement.

24. The computing arrangement of claim 22, further comprising a user interface communicatively coupled to the PDB builder module, the user interface configured and arranged to selectively modify the data structure.

25. The computing arrangement of claim 22, wherein the at least one computing arrangement component is selected from a group comprising an Input/Output Processor, a Small Computer Systems Interface (SCSI) channel, a control unit, a tape drive, and a disk drive.

26. The computing arrangement of claim 23, wherein the file arrangement is communicated to the emulator operating system during the emulator operating system'"'"'s boot process.

27. The computing arrangement of claim 23, wherein the file arrangement is retrieved by the emulator operating system during the emulator operating system'"'"'s boot process.
