Abstract

Systems and methods are disclosed that collect information for entries in a list. Multiple versions of the entries are maintained in a version object base. The elements are determined to be removable based on whether the elements are private versions or master versions.

Claims

1. An apparatus comprising:

computer-executable logic instructions operable to;

collect information for element entries in a list, wherein multiple versions of elements are maintained in a version object base;

determine whether the elements are removable based on whether the elements are at least one of the group of;

private files and locally mastered elements; and

skip elements that are not removable.

2. The apparatus of claim 1, wherein the entries in the list are associated with elements that reside in a lost+found directory.

3. The apparatus of claim 1, further comprising:

logic instructions operable to;

select between different removal procedures based on whether the entry is a Version Object Base (VOB) symbolic link entry.

4. The apparatus of claim 1, further comprising:

logic instructions operable to;

generate a report indicating whether the elements were removed.

5. The apparatus of claim 1, further comprising:

logic instructions operable to;

determine whether any versions of the elements are checked-out.

6. The apparatus of claim 1, further comprising:

logic instructions operable to;

determine whether the elements were created within a specified period of time.

7. The apparatus of claim 1, further comprising:

logic instructions operable to;

skip removal of elements and VOB symbolic link entries associated with elements that are not locally mastered.

8. The apparatus of claim 1, further comprising:

logic instructions operable to;

determine whether the last operation on the elements occurred less than a specified amount of time ago.

9. The apparatus of claim 1, further comprising:

logic instructions operable to;

determine whether custom policies are implemented.

10. The apparatus of claim 9, further comprising:

logic instructions operable to;

determine the number of task branches that exist for the elements;

remove the elements that are not associated with the task branches; and

skip the entries for the elements that are associated with the task branches.

11. A method comprising:

removing an element from a version object base (VOB) in a computer system, wherein more than one version of the element can exist, and removal of the element is based on at least one of the group of;

whether the element is a master version and whether there are any versions of the element currently checked-out.

12. The method of claim 11, further comprising:

determining whether to remove the element based on whether the element is a View private file.

13. The method of claim 11, further comprising:

reporting whether the element was removed.

14. The method of claim 11, further comprising:

determining how to remove the element based on whether an entry for the element is a symbolic link.

15. The method of claim 11, further comprising:

determining whether to remove the element based on the age of the element.

16. The method of claim 11, further comprising:

determining whether to remove the element based on the amount of time since the element was last accessed.

17. The method of claim 11, further comprising:

determining whether the element has multiple versions; and

collecting information for the multiple versions; and

deleting the multiple versions.

18. A computer product comprising:

a clean-up utility program operable to remove unused versions of elements taking into account a first set of policies and a set of custom policies.

19. The computer product of claim 18, wherein the first set of policies include ClearCase configuration management policies.

20. The computer product of claim 18, wherein the custom policies include Jazz Project policies.

21. The computer product of claim 18, wherein the clean-up utility program is further operable to:

determine whether to remove the elements based on the age of the elements.

22. The computer product of claim 18, further comprising:

logic instructions operable to;

determine whether to remove the elements based on the last time the elements were accessed.

23. The computer product of claim 18, further comprising:

logic instructions operable to;

determine whether to remove the elements based on whether the elements are master versions.

24. The computer product of claim 18, further comprising:

logic instructions operable to;

determine whether the elements has multiple versions;

collect information for the multiple versions; and

delete the multiple versions.

25. The computer product of claim 18, further comprising:

a processor configured to execute the logic instructions.

26. The computer product of claim 18, further comprising:

a software development environment configured to interface with the first set of policies and the custom policies.

27. The computer product of claim 18, further comprising:

logic instructions operable to;

interface with other computer systems via a communication network; and

determine whether versions of the elements exist on the other computer systems via the communication network.

28. The computer product of claim 19, wherein entries for the elements in the list reside in a version object base lost+found directory.
