Abstract

A method of replicating on a test server a production load of a production server. The method can include creating the production load on the production server by processing client requests received from clients. The method further can include, while the client requests are processed, via a processor, in real time, replicating the production load to generate a replicated production load that represents the client requests and defines state information representing unique states formed between the production server and the respective clients. The method also can include, in real time, communicating the replicated production load in order to replicate the production load on the test server.

Claims

1. A method of replicating on a test server a production load of a production server, the method comprising:

creating the production load on the production server by processing client requests received from clients;

while the client requests are processed, via a processor, in real time, replicating the production load to generate a replicated production load that represents the client requests and defines state information representing unique states formed between the production server and the respective clients; and

in real time, communicating the replicated production load in order to replicate the production load on the test server.

2. The method of claim 1, further comprising:

configuring an audit facility to automatically generate the replicated production load in real time while the client requests are processed by the production server.

3. The method of claim 1, further comprising:

identifying respective production socket connections via which a plurality of the client requests are communicated from the respective clients to the production server; and

associating the production socket connections with the replicated production load.

4. The method of claim 1, wherein the state information indicates cookies associated with the client requests that vary based on prior usage of the production server.

5. The method of claim 1, wherein the state information indicates page services provided to the respective clients.

6. The method of claim 1, wherein the state information indicates connection handles allocated for the respective clients.

7. The method of claim 1, wherein the state information indicates bind information associated with the respective client requests.

8. The method of claim 1, wherein replicating the production load to generate the replicated production load comprises:

replicating the production load without altering a behavior of the production server with respect to services provided to the clients by the production server.

9. A method of replicating on a test server a production load of a production server, the method comprising:

receiving a replicated production load corresponding to a production load on the production server created by processing client requests, wherein the replicated production load is generated in real time while the client requests are processed by the production server and defines state information representing unique states formed between the production server and the clients from which the client requests are received;

responsive to receiving the replicated production load, in real time, via a processor, processing the replicated production load to generate a plurality of replicated client requests, wherein each of the replicated client requests replicates a respective client request received by the production server and at least a portion of the replicated client requests define the state information associated with the respective client from which the client request is received; and

in real time, communicating the replicated client requests to the test server.

10. The method of claim 9, wherein:

the client requests are communicated from the clients to the production server via production socket connections established between the respective clients and the production server; and

processing the replicated production load to generate the plurality of replicated client requests comprises, for a plurality of the client requests, mapping corresponding production socket connections to respective test socket connections associated with the corresponding replicated client requests.

11. The method of claim 9, wherein the state information indicates cookies associated with the respective clients that vary based on prior usage of the production server.

12. The method of claim 9, wherein the state information indicates page services provided to the respective clients.

13. The method of claim 9, wherein the state information indicates connection handles allocated for the respective clients.

14. The method of claim 9, wherein the state information indicates bind information associated with the respective client requests.

15. The method of claim 9, further comprising:

filtering the replicated production load to prevent certain client requests from being replicated to the test server.
