Abstract

A method of performing a software operation on a target of one of more processors in a distributed processing system wherein another processor is designated as a server. The method includes running a configuration program on the server to condition the server to serve on the target, the software operation which includes resource creation and object definitions; testing entry conditions in the configuration program for determining if entry conditions are met to serve the software operation on the target; if the entry conditions are met, serving the software operation on the target; at the completion of the software operation, testing exit conditions in the configuration program for determining if the software operation on the target completed successfully; if the exit conditions are met, exiting the software operation; returning to the configuration program to serve a second software operation on the target; and repeating until all software operations are served on the target.

Claims

1. In a distributed processing system having multiple processors, one processor being designated a server and one or more other processors being designated a target, a method of performing software operations by the server on the target comprising the steps of:

a) running a configuration program on the server to condition the server to serve on the target a single-function software operation, said configuration program comprising single-function software operations including resource creation and object definitions;

b) testing by said server, entry conditions in said configuration program for determining if entry conditions are met to serve said single-function software operation on said target;

c) in the event said entry conditions are met, serving said single-function software operation on said target;

d) at the completion of said single-function software operation, testing at said server exit conditions in said configuration program for determining if said single-function software operation on said target completed successfully;

e) in the event said exit conditions are met, exiting said single-function software operation;

f) returning to said configuration program to serve another single-function software operation on said target; and

g) repeating steps b-f until all single-function software operations set for said target are completed.

2. The method of claim 1 wherein step a) includes selecting said single-function software operation from one of installing software on said target, migrating software from said server to said target, booting said target from a disk, or diagnosing said target.

3. The method of claim 1 further comprising after step b), in the event said entry conditions are not met, the steps of issuing an error message to said server, and exiting from said single-function software operation with an error return code indicating the single-function software operation has become a failed single-function software operation and has ceased due to an error.

4. The method of claim 3 further comprising after step d), in the event said exit conditions are not met, the steps of undoing any partial resource creation or object definition performed during said single-function software operation, issuing an error message to said server, and exiting from said single-function software operation with an error return code indicating the single-function software operation has become a failed single-function software operation which has ceased due to an error.

5. The method of claim 4 further comprising the steps of examining any issued error messages, correcting errors which caused said failed single-function software operations, creating a set of corrected single-function software operations to rerun said failed single-function software operations, and repeating steps b-f for said corrected single-function software operations until all corrected single-function software operations are completed.

6. A distributed processing system having multiple processors comprising:

a server selected from said multiple processors;

a target comprising one or more of the other processors of said multiple processors;

a configuration program on said server for performing software operations by the server on said target, said configuration program performing the steps of;

a) conditioning the server to serve on the target a single-function software operation, said configuration program comprising single-function software operations including resource creation and object definitions;

b) testing by said server, entry conditions in said configuration program for determining if entry conditions are met to serve said single-function software operation on said target;

c) in the event said entry conditions are met, serving said single-function software operation on said target;

d) at the completion of said single-function software operation, testing at said server exit conditions in said configuration program for determining if said single-function software operation on said target completed successfully;

e) in the event said exit conditions are met, exiting said single-function software operation;

f) returning to said configuration program to serve another single-function software operation on said target; and

g) repeating steps b-f until all single-function software operations set for said target are completed.

7. The distributed processing system of claim 6 wherein said configuration program further comprises in step a) includes selecting said single-function software operation from one of installing software on said target, migrating software from said server to said target, booting said target from a disk, or diagnosing said target.

8. The distributed processing system of claim 6 wherein said configuration program further comprises after step b), in the event said entry conditions are not met, the steps of issuing an error message to said server, and exiting from said single-function software operation with an error return code indicating the single-function software operation has become a failed single-function software operation and has ceased due to an error.

9. The distributed processing system of claim 8 wherein said configuration program further comprises after step d), in the event said exit conditions are not met, the steps of undoing any partial resource creation or object definition performed during said single-function software operation, issuing an error message to said server, and exiting from said single-function software operation with an error return code indicating the single-function software operation has become a failed single-function software operation which has ceased due to an error.

10. The distributed computer system of claim 9 wherein said configuration program further comprises the steps of examining any issued error messages, correcting errors which caused said failed single-function software operations, creating a set of corrected single-function software operations to rerun said failed single-function software operations, and repeating steps b-f for said corrected single-function software operations until all corrected single-function software operations are completed.
