Abstract

Various embodiments for retaining diagnostic information for data in a computing storage environment. In one such embodiment, a diagnostic component, apart from a volume table of contents (VTOC), associated with an integrated catalog facility (ICF) catalog and with a base data set from data sets via a catalog association record, is initialized. The diagnostic component is configured to retain base data set-specific diagnostic information retrievable by the computing storage environment to assist in error diagnosis. The base data set-specific diagnostic information is stored pursuant to at least one detected event associated with the base data set.

First claim

What is claimed is:

1. A method for retaining diagnostic information for data in a computing storage environment by a processor device, comprising:
initializing a diagnostic component, apart from a volume table of contents (VTOC), that is associated with an integrated catalog facility (ICF) catalog and with a base data set from a plurality of data sets via a catalog association record, wherein the diagnostic component is configured to retain base data set-specific diagnostic information retrievable by the computing storage environment to assist in error diagnosis;
storing the base data set-specific diagnostic information pursuant to at least one event associated with the base data set; and
detecting the at least one event associated with a data set, wherein the at least one event includes at least one of opening the data set and performing a backup operation for the data set.

2. The method of claim 1 , wherein storing the base data set-specific diagnostic information pursuant to the at least one event associated with the base data set includes performing at least one of:
tracking a number of times the base data set is opened for output,
logging at least one of a job, system, time of open, time of close, and a high used relative byte address at a time of closure,
tracking a last backup data set,
logging at least one of a backup name, backup location, and backup date,
logging a history of each system that accesses the base data set,
logging at least one prior error event,
logging an enqueue (ENQ) operation performed subsequent to an address space failure, and
logging extent information associated with the base data set.

3. The method of claim 2 , wherein logging the at least one prior error event further includes logging at least one error message previously issued against the base data set.

4. The method of claim 3 , wherein logging the at least one error message previously issued against the base data set further includes indicating in, by an owning application, that an error event type associated with the at least one prior error event should be logged in the diagnostic component.

5. The method of claim 1 , wherein initializing the diagnostic component is performed pursuant to one of creating the base data set and adding the diagnostic component to a preexisting base data set.

6. The method of claim 1 , further including:
monitoring for one of an error and error messages,
detecting one of the error and the error message, and
retrieving the base data set-specific diagnostic information from the base data set determined to have caused the error.

7. The method of claim 1 , further including, upon detecting the at least one event associated with the data set, performing each of:
scanning message text to extract a name of the data set, and
performing a catalog locate operation, wherein the data set-specific diagnostic information relating to the event is stored in the diagnostic component if a determination is made that the data set has an accompanying diagnostic component.

8. A system for retaining diagnostic information for data in a computing storage environment, comprising:
a diagnostic component;
at least one processor device operable in the computing storage environment and in association with the diagnostic component;
a data set module operational by the at least one processor device in the computing storage environment, wherein the data set module:
initializes the diagnostic component, apart from a volume table of contents (VTOC), and is associated with an integrated catalog facility (ICF) catalog and a base data set from a plurality of data sets via a catalog association record, wherein the diagnostic component is configured to retain base data set-specific diagnostic information retrievable by the computing storage environment to assist in error diagnosis,
stores the base data set-specific diagnostic information pursuant to at least one event associated with the base data set, and
detects the at least one event associated with a data set, wherein the at least one event includes at least one of opening the data set and performing a backup operation for the data set.

9. The system of claim 8 , wherein the data set module, for storing the base data set-specific diagnostic information pursuant to the at least one event associated with the base data set, performs at least one of:
tracking a number of times the base data set is opened for output,
logging at least one of a job, system, time of open, time of close, and a high used relative byte address at a time of closure,
tracking a last backup data set,
logging at least one of a backup name, backup location, and backup date,
logging a history of each system that accesses the base data set,
logging at least one prior error event,
logging an enqueue (ENQ) operation performed subsequent to an address space failure, and
logging extent information associated with the base data set.

10. The system of claim 9 , wherein the data set module logs at least one error message previously issued against the base data set.

11. The system of claim 8 , wherein the diagnostic component is an appendage to the base data set, and the catalog association record is used to direct the base data set-specific diagnostic information to a correct location.

12. The system of claim 11 , wherein the at least one prior error event includes at least one error message previously issued against the base data set.

13. The system of claim 12 , further including an owing application in communication with the data set module, wherein the owning application indicates in the at least one prior error event that an error event type associated with the at least one prior error event should be logged in the diagnostic component.

14. The system of claim 8 , wherein the data set module initializes the diagnostic component pursuant to one of creating the base data set and adding the diagnostic component to a preexisting base data set.

15. The system of claim 8 , wherein the at least one processor device performs at least one of:
monitoring for one of an error and error messages,
detecting one of the error and the error message, and
retrieving the base data set-specific diagnostic information from the base data set determined to have caused the error.

16. The system of claim 8 , wherein the at least one processor device, upon detecting the at least one event associated with the data set, performing each of:
scanning message text to extract a name of the data set, and
performing a catalog locate operation, wherein the data set-specific diagnostic information relating to the event is stored in the diagnostic component if a determination is made that the data set has an accompanying diagnostic component.

17. A computer program product for retaining diagnostic information for data using a processor device in a computing storage environment, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
an executable portion that initializes a diagnostic component, apart from a volume table of contents (VTOC), that is associated with an integrated catalog facility (ICF) catalog and with a base data set from a plurality of data sets via a catalog association record, wherein the diagnostic component is configured to retain base data set-specific diagnostic information retrievable by the computing storage environment to assist in error diagnosis;
an executable portion that stores the base
