Abstract

Replicating on a test server a production load of a production server. The production load can be created on the production server by processing client requests received from clients. While the client requests are processed, in real time, the production load can be replicated 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. In real time, the replicated production load can be communicated in order to replicate the production load on the test server.

Claims

1. A computer program product for replicating on a test server a production load of a production server, the computer program product comprising:

a computer-readable storage device having computer-readable program code embodied therewith, the computer-readable program code comprising instructions executable by at least one processor, the computer-readable program code comprising;

computer-readable program code configured to receive 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

computer-readable program code configured to, responsive to receiving each message, in real time, determine whether the message satisfies certain criteria for ignoring the message and, if the message does not satisfy the certain criteria for ignoring the message, parse data from the message and, from the parsed data, generate the 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, communicate the replicated client request to a test server in order to replicate the production load on the test server.

2. The computer program product of claim 1, the computer-readable program code further comprising:

computer-readable program code configured to configure 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 computer program product of claim 1, the computer-readable program code further comprising:

computer-readable program code configured to identify a respective production socket connection via which the client request is communicated from the respective client to the production server;

wherein the computer-readable program code configured to communicate 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 computer program product 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 computer program product of claim 1, wherein the state information indicates at least one page service provided to the respective client.

6. The computer program product of claim 1, wherein the computer-readable program code configured to communicate the replicated client request to the test server in order to replicate the production load on the test server comprises:

computer-readable program code configured to communicate the replicated client request to the test server without altering a behavior of the production server with respect to services provided to clients by the production server.

7. A computer program product for replicating on a test server a production load of a production server, the computer program product comprising:

a computer-readable storage device having computer-readable program code embodied therewith, the computer-readable program code comprising instructions executable by at least one processor, the computer-readable program code comprising;

computer-readable program code configured to receive 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;

computer-readable program code configured to, responsive to receiving the replicated production load, in real time, process the replicated production load to generate a plurality of replicated client requests, wherein processing the replicated production load comprises filtering the replicated production load to prevent certain client requests from being replicated, 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

computer-readable program code configured to, in real time, communicate the replicated client requests to the test server.

8. The computer program product of claim 7, 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

the computer-readable program code configured to process the replicated production load to generate the plurality of replicated client requests comprises computer-readable program code configured to, for a plurality of the client requests, map corresponding production socket connections to respective test socket connections associated with the corresponding replicated client requests.
