Abstract

A heterogeneous configuration management tool enables building of a software system in a heterogeneous network of computers. In building a desired software system, the tool enables at least one component of the system to be translated by a foreign computer of the network and other components of the system to be translated by other computers of the network. A reference to a version indicator is passed to the foreign computer to provide the foreign computer an indication of user-specified version of the component being translated by the foreign computer. The reference is expanded during processing on the foreign computer. Pathname transformation files are employed to provide transformation of a pathname in one computer of the network to a corresponding pathname in another computer of a network. Binaries resulting from component translations are stored in split pools. In turn, split releases of the built software system are enabled.

3. Apparatus as claimed in claim 2 wherein the one computer directory resides on one computer of the network and the second directory resides on another computer in the network.

4. Apparatus as claimed in claim 2 further comprising a release directory formed of a first part and a second part, the first part for containing bound configuration threads used in building the desired software system and the second part for containing derived objects held in the pool second portion, the first part and second part residing in one of a common computer directory and separate computer directories.

5. Apparatus as claimed in claim 1 wherein the computers of the network are categorized into user-predetermined host types, the first computer being of a different host type than the foreign computer.

6. Apparatus as claimed claim 5 wherein each system component is user-assigned a respective host type such that the component is translated by a computer of the assigned host type.

7. Apparatus as claimed in claim 6 wherein in response to a change to a different host type of a component the configuration managing member provides that the component is translated by a computer of that host type.

8. Apparatus as claimed in claim 6 wherein the components of the system are of different host types such that the desired software system comprises components of mixed host type.

9. Apparatus as claimed in claim 1 wherein one of the computers including the first computer in the network is a helper node;

the configuration managing member enables a component to be translated by the foreign computer by initiating build process on the helper node and in response the helper node establishes and invokes a shell build script for the foreign computer to translate the system component.

10. Apparatus as claimed in claim 1 wherein the components of the software system are of respective user-specified versions;

and

the configuration managing member employs a version indicator for providing to the foreign computer an indication of the user-specified version of the component to be translated by the foreign computer.

11. Apparatus as claimed in claim 10 wherein the version indicator further provides the foreign computer a set of user-desired build attributes for building the software system.

12. Apparatus as claimed in claim 10 wherein the version indicator is passed to the foreign computer in a pathname.

13. Apparatus as claimed in claim 12 wherein the version indicator comprises a pointer name, and the pathname passed to the foreign computer comprises a directory path followed by the pointer name followed by name of the component to be translated by the foreign computer.

14. Apparatus as claimed in claim 1 further comprising a pathname transformation file for providing transformation of a pathname in one computer of the network to a corresponding pathname in another computer of the network.

15. Apparatus as claimed in claim 1 further comprising a build manager for selecting, for each component of the desired software system, a computer of the network to build the component.

16. Method of building a desired software system having a multiplicity of components, each component being derivable from a respective source element by translation of the source element to an output element, the method comprising the steps of:

providing a plurality of computers in a heterogeneous network, one computer being a foreign computer that generates binaries different from binaries generated by other computers of the network;

for at least one component of a software system desired to be built in the network, invoking a translation process on the foreign computer such that a foreign computer output element of each of the at least one component is generated from the respective source element of the one component;

for each remaining component of the desired software system, translating the source element of the component on another computer of the network to generate an output element from that computer for the component;

combining output elements, including foreign computer output elements of the software system components to build the desired software system; and

storing binaries of translated source elements of the components on one of the computers of the network.

17. A method as claimed in claim 16 wherein the step of invoking a translation process on the foreign computer includes:

establishing a first shell on the foreign computer;

within the first shell providing a second shell in which set-up and clean-up tasks of the translation process are performed; and

executing the translation process in a third shell.

18. A method as claimed in claim 16 further comprising the step of forming a release directory having a first part containing bound configuration threads used in building the desired software system and a second part containing a copy of the binaries, the first and second parts residing on one of a common computer directory and separate computer directories.
