Abstract

Embodiments of the present invention provide systems and method for improving platform dump collection. The method includes upon receiving a platform dump request for a system, accessing a model of the system hardware and a list of commands for the dump. The method further includes determining whether a constraint exists for the command in the list, identifying which software and hardware locks are required by the constraints, determining whether a hardware and software lock is required by multiple constraints, generating a grouping of the constraints requiring the hardware and software lock, and generating an executable list of commands.

Claims

determining, by one or more processors, that the first hardware and software lock of the one or more hardware and software locks is not required by a third constraint of the one or more constraints; and

responsive to determining that the first hardware and software lock is not required by the third constraint, determining, by one or more processors, whether the first hardware and software lock is held.

4. The method of claim 3, further comprising:

responsive to determining that the first hardware and software lock is held, adding, by one or more processors, a command from the plurality of commands that require the first hardware and software lock to the executable list of commands.

5. The method of claim 3, further comprising:

responsive to determining the first hardware and software lock is not held, holding, by one or more processors, the first hardware and software lock; and

responsive to holding the first hardware and software lock, including, by one or more processors, in the executable list, a command from the plurality of commands in the list that requires the one or more constraints that requires the first hardware and software lock.

6. The method of claim 1, further comprising:

executing, by one or more processors, the executable list of commands.

7. The method of claim 3, further comprising:

responsive to determining that the first hardware and software lock of the one or more hardware and software locks is not required by the third constraint, executing, by one or more processors, a command from the plurality of commands in the list that requires the third constraint.

8. A computer program product for improving platform dump collection, the computer program product comprising:

one or more computer readable storage medium and program instructions stored on the computer readable storage medium, the program instructions comprising;
