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:

receiving from the production server a plurality of messages representing the production load on the production server, each message corresponding to a respective client request received from a respective client; and

responsive to receiving each message, in real time, parsing data from the message and, from the parsed data, generating a replicated client request corresponding to the client request, wherein the replicated client request comprises state information representing a unique state formed between the production server and the respective client, and, in real time, communicating the replicated client request to a test server, without altering a behavior of the production server with respect to services provided to clients by the production server, 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, by the production server, the message corresponding to the respective client request in real time responsive to the client request being processed by the production server.

3. The method of claim 1, further comprising:

identifying a respective production socket connection via which the client request is communicated from the respective client to the production server;

wherein communicating the replicated client request to the test server in order to replicate the production load on the test server comprises communicating the replicated client request via a test socket connection correlating to the production socket connection.

4. The method of claim 1, wherein the state information indicates at least one cookie associated with the client request based on prior usage of the production server.

5. The method of claim 1, wherein the state information indicates at least one page service provided to the respective client.

6. The method of claim 1, wherein the state information indicates a connection handle allocated for the respective client.

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

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

receiving from the production server 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, filtering the replicated production load to prevent certain client requests from being replicated to the test server and processing the filtered 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.

9. The method of claim 8, 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.

10. The method of claim 8, wherein the state information indicates cookies associated with the respective clients that vary based on prior usage of the production server.

11. The method of claim 8, wherein the state information indicates page services provided to the respective clients.

12. The method of claim 8, wherein the state information indicates connection handles allocated for the respective clients.

13. The method of claim 8, wherein the state information indicates bind information associated with the respective client requests.
