Abstract

A system and method are provided for processing directory service operations. The system includes a client device communicatively coupled to one or more directory servers. Each directory server includes a communications interface, a storage mechanism, and an evaluation module. According to an exemplary embodiment, the storage mechanism is a non-persistent storage mechanism which increases read and write performance. When a directory server receives a directory service operation, it determines whether it is capable of processing the operation, and if so, processes it with respect to its non-persistent storage mechanism. If the directory service operation is an update operation, the operation is broken up into permanent data and temporary data. The permanent data is written to a persistent storage mechanism whereas the temporary data is written to a non-persistent storage mechanism. In some embodiments, the permanent data is additionally written to a non-persistent storage mechanism.

Claims

1. In a directory system, a method of executing a directory operation which includes an update, the method comprising the steps of:

breaking up said operation which includes an update into permanent data and temporary data; and

performing an operation which includes an update based on whether the data type is permanent or temporary.

2. A method according to claim 1, wherein said permanent data is written to a persistent storage mechanism.

3. A method according to claim 2, wherein an additional determination is made as to whether to write said permanent data to a non-persistent storage mechanism.

4. A method according to claim 1, wherein said temporary data is written to a non-persistent storage mechanism.

5. A method according to claim 2, wherein said persistent storage mechanism is at least one from the group consisting of a hard drive, a disk, a file system, and a network drive.

6. A method according to claim 1, wherein said operation which includes an update is broken up according to at least one of the criteria from the group consisting of the directory attribute type, the value of an attribute type, and the attribute is user selected.

7. A method according to claim 1, wherein said operation which includes an update is at least one from the group consisting of an add-entry operation, a remove-entry operation, a modify-entry operation, a modify-dn operation, a bind operation, a compare operation, and a read operation.

8. A method according to claim 4, wherein said non-persistent storage mechanism is at least one from the group consisting of an alternate evaluator and a memory-resident table.

9. A method according to claim 1, wherein said operation which includes an update comprises operations as defined in a standard from the group consisting of X.500, LDAP, and DSML.

10. A directory server for processing directory service operations comprising:

a communications interface configured to receive one or more directory service operations from one or more client devices;

at least one non-persistent storage mechanism;

at least one persistent storage mechanism; and

an evaluation module to breakup an operation which includes an update into temporary data and permanent data.

11. A directory server according to claim 10, wherein said evaluation module writes said permanent data to said persistent storage mechanism.

12. A directory server according to claim 11, wherein said evaluation module makes an additional determination as to whether to write said permanent data to said non-persistent storage mechanism.

13. A directory server according to claim 10, wherein said evaluation module writes said temporary data to said non-persistent storage mechanism.

14. A directory server according to claim 10, wherein said non-persistent storage mechanism is a internal memory resident table.

15. A directory server according to claim 10, wherein said non-persistent storage mechanism is an alternate evaluator.

16. A directory server according to claim 10, wherein said directory operations comprise operations as defined in a standard from the group consisting of X.500, LDAP, and DSML.

17. In a directory system, a method of executing an operation which includes an update, the method comprising the steps of:

breaking up said operation which includes an update into permanent data and temporary data;

writing said permanent data to a persistent storage mechanism; and

writing said temporary data to a non-persistent storage mechanism.

18. A method according to claim 17, further consisting of the step of:

determining whether said permanent data should be written to said non-persistent storage mechanism; and

writing said permanent data to said non-persistent storage mechanism if said determination is positive.
