Abstract

A system for archiving includes an active memory, an archive memory, an interface, and a processor. The interface is to receive an indication to archive an object in the active memory. The object has a relation to an other object. The processor is to archive the object in the archive memory. The other object maintains the relation with the object that has been archived.

Claims

1. A system for archiving, comprising:

an active memory;

an archive memory;

an interface configured to;

receive an indication to archive an object in the active memory, wherein an object tree is comprised of a plurality of objects, wherein the plurality of objects of the object tree are stored in the active memory, wherein a subtree of the object tree comprises the object and a subset of the plurality of objects, wherein the object has a relation to an other object in the active memory, wherein the object tree comprises the other object and the subtree does not comprise the other object, wherein the object is an root object of the subtree and the subset of the plurality of objects include one or more member objects of the subtree; and

a processor configured to;

in response to receiving the indication to archive the object prepare the object to be archived, wherein to prepare the object to be archived, the processor is configured to;

flag the object as archive prepared by setting an attribute bit associated with the object in an object data table;

monitor the object for accesses, comprising determining a number of object accesses associated with the object; and

determine a number of object accesses associated with the object that do not have archive permission;

archive in the archive memory the object and the subset of the plurality of objects based on the determined number of object access associated with the object and the determined number of object accesses associated with the object that do not have archive permission; and

maintain the relation between the other object stored in the active memory and the archived object stored in the archive memory, wherein to maintain the relation between the other object stored in the active memory and the archived object stored in the archive memory, the processor is configured to enable the archived object stored in the archive memory to be accessed from the other object stored in the active memory by traversing the object tree stored in the active memory from the other object to the archived object stored in the archive memory.

2. The system of claim 1, wherein the active memory comprises a DRAM.

3. The system of claim 1, wherein an active database system is stored in the active memory.

4. The system of claim 1, wherein an object database is stored at least in part in the active memory.

5. The system of claim 1, wherein the archive memory comprises a disk.

6. The system of claim 1, wherein the object is stored in an object database.

7. The system of claim 1, wherein the object comprises attributes.

8. The system of claim 1, wherein the object comprises methods.

9. The system of claim 1, wherein the object comprises relations.

10. The system of claim 1, wherein to maintain the relation, the processor is configured to maintain an ability of a user or a process to follow the relation.

11. The system of claim 10, wherein a permission is required for the user or the process to follow the relation.

12. The system of claim 10, wherein following the relation comprises accessing the object.

13. The system of claim 1, wherein to archive the object, the processor is configured to store the object in the archive memory.

14. The system of claim 1, wherein to archive the object, the processor is configured to delete the object from the active memory.

15. The system of claim 1, wherein to archive the object, the processor is configured to flag the object as immutable to a user.

16. The system of claim 1, wherein the processor is further configured to unarchive an archived object.

17. The system of claim 16, wherein to unarchive the archived object, the processor is configured to restore the object to the active memory.

20. The system of claim 1, wherein the processor is further configured to:

in response to an exceeding determination that the number of object accesses exceeds a threshold within a predetermined period of time, unflag the object as archive prepared.

21. The system of claim 1, wherein the number of object accesses comprises a count of attempts to access the object.

22. The system of claim 1, wherein the number of object accesses comprises a count of object accesses without archive permission.

18. A method for archiving, comprising:

receiving an indication to archive an object in an active memory, wherein an object tree is comprised of a plurality of objects wherein the plurality of objects of the object tree are stored in the active memory, wherein a subtree of the object tree comprises the object and a subset of the plurality of objects, wherein the object has a relation to an other object in the active memory, wherein the object tree comprises the other object and the subtree does not comprise the other object, wherein the object is an root object of the subtree and the subset of the plurality of objects include one or more member objects of the subtree;

in response to receiving the indication to archive the object preparing the object to be archived, wherein preparing the object to be archived comprises;

flagging the object as archive prepared by setting an attribute bit associated with the object in an object data table;

monitoring the object for accesses, comprising determining a number of object accesses associated with the object; and

determining a number of object accesses associated with the object that do not have archive permission;

archiving in an archive memory, using a processor, the object and the subset of the plurality of objects based on the determined number of object access associated with the object and the determined number of object accesses associated with the object that do not have archive permission; and

maintaining the relation between the other object stored in the active memory and the archived object stored in the archive memory, wherein maintaining the relation between the other object stored in the active memory and the archived object stored in the archive memory comprises enabling the archived object stored in the archive memory to be accessed from the other object stored in the active memory by traversing the object tree stored in the active memory from the other object to the archived object stored in the archive memory.

19. A computer program product for archiving, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving an indication to archive an object in an active memory, wherein an object tree is comprised of a plurality of objects wherein the plurality of objects of the object tree are stored in the active memory, wherein a subtree of the object tree comprises the object and a subset of the plurality of objects, wherein the object has a relation to an other object in the active memory, wherein the object tree comprises the other object and the subtree does not comprise the other object, wherein the object is an root object of the subtree and the subset of the plurality of objects include one or more member objects of the subtree;

in response to receiving the indication to archive the object preparing the object to be archived, wherein preparing the object to be archived comprises;

flagging the object as archive prepared by setting an attribute bit associated with the object in an object data table;

monitoring the object for accesses, comprising determining a number of object accesses associated with the object; and

determining a number of object accesses associated with the object that do not have archive permission;

archiving in an archive memory the object and the subset of the plurality of objects based on the determined number of object access associated with the object and the determined number of object accesses associated with the object that do not have archive permission; and

maintaining the relation between the other object stored in the active memory and the archived object stored in the archive memory, wherein maintaining the relation between the other object stored in the active memory and the archived object stored in the archive memory comprises enabling the archived object stored in the archive memory to be accessed from the other object stored in the active memory by traversing the object tree stored in the active memory from the other object to the archived object stored in the archive memory.
