Abstract

In embodiments, servers within a distributed system include more than one thread pool from which threads may be allocated for processing requests received at the servers. The servers have a local thread pool from which threads for processing requests that require only local resources (resources stored locally on the server) are allocated. In embodiments, the server will include a remote thread pool from which threads are allocated for processing requests that require resources stored on any remote server. In other embodiments, the server will include a corresponding thread pool for each of a number of specified remote servers. When a request requires access to resources stored on a particular server, a thread from the corresponding thread pool associated with the particular server will be allocated for processing the request.

Claims

1. A computer implemented method of processing a request, wherein the processing requires resources stored on a distributed system, the method comprising:

receiving at a receiving server a request for processing, wherein the receiving server comprises a local thread pool and a remote thread pool;

determining by the receiving server where the resources required for processing the request are stored;

in response to a determination that the resources are stored remotely on a remote server, allocating a thread from the remote thread pool for processing the request;

in response to a determination that the resources are stored locally on the receiving server, allocating a thread from the local thread pool for processing the request; and

processing the request.

2. The method of claim 1, wherein the remote server is a first remote server and the remote thread pool is associated with the first remote server.

3. The method of claim 2, wherein the receiving server further comprises a second remote thread pool.

4. The method of claim 3, further comprising:

in response to a determination that the resources are stored remotely on a second remote server, allocating a thread from the second remote thread pool for processing the request.

5. The method of claim 3, wherein the second remote thread pool is associated with a second remote server.

6. The method of claim 1, wherein the remote server is a first remote server, and the method further comprises:

in response to a determination that the resources are stored remotely on a second remote server, allocating a thread from the remote thread pool for processing the request.

7. The method of claim 2, further comprising:

in response to a determination that the resources are stored remotely on a second remote server, allocating a thread from the local thread pool for processing the request.

8. The method of claim 1, wherein the local thread pool comprises more threads than the remote thread pool.

9. The method of claim 1, wherein the receiving server is a directory server.

10. The method of claim 9, wherein the resources comprise a directory and the request relates to accessing the directory.

11. The method of claim 10, wherein the request is in the form of a Light Directory Access Protocol (LDAP) request.

12. A computer readable medium storing computer executable instructions for performing a method of processing a request, wherein the processing requires access to resources stored on a distributed system, the method comprising:

receiving at a receiving server a request for processing, wherein the receiving server comprises a local thread pool, a first server thread pool associated with a first remote server, and a second server thread pool associated with a second remote server;

determining where resources required for processing the request are stored;

in response to a determination that the resources are stored on the receiving server, allocating a thread from the local thread pool for processing the request; and

in response to a determination that the resources are stored on the first remote server, allocating a thread from the first server thread pool for processing the request;

in response to a determination that the resources are stored on the second remote server, allocating thread from the second server thread pool for processing the request.

13. The computer readable medium of claim 12, wherein the receiving server further comprises a remote thread pool, wherein the remote thread pool is not associated with any specific remote server.

14. The computer readable medium of claim 13, further comprising:

in response to a determination that the resources are stored remotely on a remote server that is not one of the first remote server or the second remote server, allocating a thread from the remote thread pool for processing the request.

15. The computer readable medium of claim 12, wherein the receiving server is a directory server.

16. The computer readable medium of claim 15, wherein the resources comprise a directory and the request relates to accessing the directory.

17. The computer readable medium of claim 16, wherein the request is in the form of a Light Directory Access Protocol (LDAP) request.

18. A computer system for processing a request, the system comprising:

a memory storing;

a local thread pool;

a remote thread pool associated with a plurality of remote servers; and

computer executable instructions that when executed perform the steps of;

receiving a request for processing;

determining where the resources required for processing the request are stored;

in response to a determination that the resources are stored remotely on one of the plurality of remote servers, allocating a thread from the remote thread pool for processing the request;

in response to a determination that the resources are stored locally, allocating a thread from the local thread pool for processing the request; and

processing the request; and

a processor for processing the computer executable instructions.

19. The system of claim 18, wherein the resources comprise a directory and the request relates to accessing the directory.

20. The system of claim 19, wherein the request is in the form of a Light Directory Access Protocol (LDAP) request.
