Abstract

In one embodiment, a computer program product for first time data capture includes a computer readable storage medium having computer readable program code embodied therewith. The computer readable program code is configured to run jobs on a systems complex (sysplex), to trace the jobs running on the sysplex, to monitor each of the jobs running on the sysplex for an unexpected action by any of the jobs, and to store information relating to each unexpected action performed by any of the jobs into an entry of a data store. In another embodiment, a method includes running jobs on a sysplex, tracing the jobs running on the sysplex, monitoring each of the jobs running on the sysplex for an unexpected action by any of the jobs, and storing information relating to each unexpected action performed by any of the jobs into an entry of a data store.

Claims

1. A computer program product for first time data capture, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:

computer readable program code configured to run one or more jobs on a systems complex (sysplex);

computer readable program code configured to trace the one or more jobs running on the sysplex, wherein an address space of the one or more jobs running on the sysplex is used to store a logical stack trace of the one or more jobs running on the sysplex;

computer readable program code configured to monitor each of the one or more jobs running on the sysplex for an unexpected action by any of the jobs; and

computer readable program code configured to store information relating to each unexpected action performed by any of the jobs into an entry of a data store, wherein the information comprises the logical stack of the one or more jobs running on the sysplex,

wherein the data store includes trace_data information for each entry.

2. The computer program product of claim 1, further comprising computer readable program code configured to create the data store having one or more entries in response to the unexpected action.

3. The computer program product of claim 1, further comprising computer readable program code configured to store the data store to a nonvolatile memory.

4. The computer program product of claim 1, further comprising computer readable program code configured to send the data store to a system administrator for diagnosing a problem with the sysplex.

5. The computer program product of claim 1, wherein the computer readable program code configured to trace comprises:

computer readable program code configured to trace one or more code_access events for each job running on the sysplex; and

computer readable program code configured to trace one or more code_branch events for each job running on the sysplex.

6. The computer program product of claim 1, wherein the computer readable program code configured to trace comprises a logical tracing algorithm.

7. The computer program product of claim 6, wherein the logical tracing algorithm is stored in an operating system of the sysplex.

8. The computer program product of claim 1, wherein the data store includes job_termination_status information for each entry.

9. The computer program product of claim 1, wherein the trace_data information for each entry comprises at least one code_access event and at least one code_branch event.

10. The computer program product of claim 1, wherein the data store is chosen from a group consisting of:

a table, an array, a list, and a database.

11. A method, comprising:

running one or more jobs on a systems complex (sysplex);

tracing the one or more jobs running on the sysplex, wherein an address space of the one or more jobs running on the sysplex is used to store a logical stack trace of the one or more jobs running on the sysplex;

monitoring each of the one or more jobs running on the sysplex for an unexpected action by any of the jobs; and

storing information relating to each unexpected action performed by any of the jobs into an entry of a data store, wherein the information comprises the logical stack of the one or more jobs running on the sysplex,

wherein the data store includes job_termination_status information for each entry.

12. The method as recited in claim 11, further comprising:

creating the data store having one or more entries in response to the unexpected action; and

storing the data store to a nonvolatile memory.

13. The method as recited in claim 11, further comprising sending the data store to a system administrator for diagnosing a problem with the sysplex.

14. The method as recited in claim 11, wherein the tracing comprises:

tracing one or more code_access events for each job running on the sysplex; and

tracing one or more code_branch events for each job running on the sysplex.

15. The method as recited in claim 11, wherein the tracing comprises a logical tracing algorithm.

16. The method as recited in claim 15, wherein the logical algorithm is stored in an operating system of the sysplex.

17. The method as recited in claim 11, further comprising indexing the data store using one or more unique keys.

18. The method as recited in claim 11, wherein the data store includes trace_data information for each entry, the trace_data information comprising at least one code_access event and at least one code_branch event.

19. The method as recited in claim 11, wherein the data store is chosen from a group consisting of:

a table, an array, a list, and a database.

20. A computer program product for first time data capture, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:

computer readable program code configured to run one or more jobs on a systems complex (sysplex);

computer readable program code configured to trace the one or more jobs running on the sysplex, wherein an address space of the one or more jobs running on the sysplex is used to store a logical stack trace of the one or more jobs running on the sysplex;

computer readable program code configured to monitor each of the one or more jobs running on the sysplex for an unexpected action by any of the jobs; and

computer readable program code configured to store information relating to each unexpected action performed by any of the jobs into an entry of a data store,

wherein the information comprises the logical stack of the one or more jobs running on the sysplex, and

wherein the data store is chosen from a group consisting of a table, an array, a list, and a database.
