Abstract

The On-Demand Cache Acquisition Tool, or “OCAT,” is a computer implemented system and process for acquiring data from a cache in a distributed network of computers, comprising: receiving a query for the data; sending the query to a remote server in the distributed network; receiving a reply from the remote server indicating that the data is in a cache coupled to the remote server; requesting a copy of the data from the remote server; receiving the copy of the data from the remote server; and storing the data in a local memory.

Claims

1. A computer implemented process for acquiring data from a cache in a distributed network of computers, the computer implemented process comprising:

receiving a query for the data;

sending the query to a remote server in the distributed network;

receiving a reply from the remote server indicating that the data is in a cache coupled to the remote server;

requesting a copy of the data from the remote server;

receiving the copy of the data from the remote server; and

storing the data in a local memory.

2. The computer implemented process of claim 1 wherein the query is sent to the remote server as a string in a message object via a JMS messaging system coupled to an enterprise bus system.

3. The computer implemented process of claim 1 wherein the reply is a string in a message object and is received via a JMS messaging system coupled with an enterprise bus system.

4. The computer implemented process of claim 1 wherein:

the distributed network has more than one remote server;

the reply is received from more than one remote server; and

the copy of the data is requested from the remote server that replied in the fastest time.

5. A computer implemented process for providing data from a cache in a distributed network of computers, the computer implemented process comprising:

receiving a query for the data from a remote server in the distributed network;

determining if the data is in a local cache;

replying to the remote server if the data is in the local cache;

receiving a request for a copy of the data; and

sending the copy of the data to the remote server.

6. The computer implemented process of claim 5 wherein the reply to the remote server is a string in a message object sent via a JMS messaging system coupled to an enterprise bus system.

7. A computer program product comprising a computer useable medium having a computer readable program, wherein the computer readable program when executed on a computer causes the computer to perform a process for acquiring data from a cache in a distributed network of computers, the process comprising:

receiving a query for the data;

sending the query to a remote server in the distributed network;

receiving a reply from the remote server indicating that the data is in a cache coupled to the remote server;

requesting a copy of the data from the remote server;

receiving the copy of the data from the remote server; and

storing the data in a local memory.

8. The computer program product of claim 7 wherein the query is sent to the remote server as a string in a message object via a JMS messaging system coupled with an enterprise bus system.

9. The computer program product of claim 7 wherein the reply is a string in a message object and is received via a JMS messaging system coupled with an enterprise bus system.

10. The computer program product of claim 7 wherein:

the distributed network has more than one remote server;

the reply is received from more than one remote server; and

the copy of the data is requested from the remote server that replied in the fastest time.

11. The computer program product of claim 7 further comprising a second computer readable program, wherein the second computer readable program when executed on the remote server causes the remote server to perform a process comprising:

receiving the query for the data;

determining if the data is in a cache coupled to the remote server;

sending a reply if the data is in the cache coupled to the remote server;

receiving a request for a copy of the data; and

sending the copy of the data to the computer.
