Abstract

A method for hybrid Discovery Library Adapter (DLA) book processing identifies a first logical group in a first DLA book, the first DLA book including a first set of objects constructed according to a Common Data Model (CDM) specification to represent a first set of corresponding instances of resources at a first time, the first logical group being a grouping of related subset of the first set of objects. A first value corresponding to the first logical group, and usable for ascertaining a difference between the first logical group and a second logical group in a second DLA book, is computed. A second value corresponding to the second logical group is computed and matched with the first value. If matched, a change in the first logical group as compared to the second logical group is identified and output to a DLA delta book.

Claims

1. A method for hybrid Discovery Library Adapter (DLA) book processing in a data processing environment, the method comprising:

identifying at an application executing using a processor and a memory, in a first DLA book a first logical group, the first DLA book including a first set of objects constructed according to a Common Data Model (CDM) specification to represent a first set of corresponding instances of resources in the data processing environment at a first time, the first logical group being a grouping of related subset of the first set of objects;

computing at the application executing using the processor and the memory, a first value corresponding to the first logical group, the first value being usable for ascertaining a difference between the first logical group in the first DLA book and a second logical group in a second DLA book, the second DLA book including a second set of objects constructed according to the CDM specification to represent a second set of corresponding instances of the resources in the data processing environment at a second time;

computing at the application executing using the processor and the memory, a second value corresponding to the second logical group, the second value being usable for ascertaining a difference between the first logical group and the second logical group;

determining whether the first value matches the second value;

identifying, responsive to the determining being affirmative, a change in the first logical group as compared to the second logical group;

outputting the change to a DLA delta book; and

transmitting the DLA delta book for loading into a DLA book repository.

2. The method of claim 1, further comprising:

computing a first file-level value for the first DLA book and a second file-level value of the second DLA book, the first and second file-level values being usable for ascertaining a difference between the first DLA book and the second DLA book; and

determining whether the first file-level value matches the second file-level value, wherein the identifying the first logical group, computing the first value, determining whether the first value matches the second value, the identifying the a change in the first logical group, and outputting the change occur responsive to the first file-level value not matching the second file-level value.

3. The method of claim 1, wherein the first logical group is specified in a file.

4. The method of claim 1, wherein the first logical group is identified without using a predefined schema for the first DLA book.

5. The method of claim 1, wherein the first and the second DLA books are constructed according to Identity Markup Language (IDML) specification.

6. The method of claim 1, wherein the application executes in a data processing system that is target of configuration discovery to collect data for the first DLA book.

7. The method of claim 1, further comprising:

omitting, responsive to the determining being negative, the first logical group from the DLA delta book.

8. The method of claim 1, wherein the first and the second values are checksums.

9. A computer usable program product comprising a computer usable storage medium including computer usable code for hybrid Discovery Library Adapter (DLA) book processing in a data processing environment, the computer usable code comprising:

computer usable code for identifying at an application executing using a processor and a memory, in a first DLA book a first logical group, the first DLA book including a first set of objects constructed according to a Common Data Model (CDM) specification to represent a first set of corresponding instances of resources in the data processing environment at a first time, the first logical group being a grouping of related subset of the first set of objects;

computer usable code for computing at the application executing using the processor and the memory, a first value corresponding to the first logical group, the first value being usable for ascertaining a difference between the first logical group in the first DLA book and a second logical group in a second DLA book, the second DLA book including a second set of objects constructed according to the CDM specification to represent a second set of corresponding instances of the resources in the data processing environment at a second time;

computer usable code for computing at the application executing using the processor and the memory, a second value corresponding to the second logical group, the second value being usable for ascertaining a difference between the first logical group and the second logical group;
