Abstract

Systems, methods, and computer readable mediums. A method includes receiving a first pre-caching rule from a policy database, receiving first data corresponding to the first pre-caching rule, and transmitting the first data to a file server cache (FSC) to be pre-cached on the FSC. The method may also include receiving a request for second data from the FSC and receiving a second pre-caching rule from the policy database. The second pre-caching rule specifies third data to be pre-cached on the FSC when the second data is requested. The method may include receiving the second data and the third data and transmitting the second data and the third data to the FSC.

Claims

1. A method performed by a server data processing system connected to communicate with a file server cache (FSC) data processing system, comprising:

receiving a first pre-caching rule from a policy database;

receiving first product assembly data corresponding to the first pre-caching rule, the first product assembly data corresponding to a first subassembly of a product;

transmitting the first product assembly data to the FSC to be pre-cached on the FSC according to the first pre-caching rule, wherein the first pre-caching rule includes a scheduling rule specifying when the first product assembly data is to be pre-cached on the FSC and specifying that when the user requests the first product assembly data, then third product assembly data, corresponding to a second subassembly of the product and part of a common bill-of-materials data structure as the first product assembly data, should be transmitted to the FSC to be pre-cached on the FSC; and

transmitting the third product assembly data to the FSC to be pre-cached on the FSC according to the first pre-caching rule.

2. The method of claim 1, wherein the first pre-caching rule defines the first product assembly data to be pre-cached at the FSC without waiting for a request from a user or other system.

3. The method of claim 1, further comprising:

receiving a request for second product assembly data from the FSC;

receiving a second pre-caching rule from the policy database, the second pre-caching rule specifying that the third product assembly data should be pre-cached on the FSC when the second data is requested;

receiving the second product assembly data and the third product assembly data; and

transmitting the second product assembly data and the third product assembly data to the FSC.

4. The method of claim 3, wherein the second product assembly data and the third product assembly data is product lifecycle management data including multiple product options and variants.

5. The method of claim 3, wherein the second data corresponds to a bill-of-materials (BOM) subassembly of a product, and the third data corresponds to a related BOM subassembly of the product.

6. The method of claim 1, further comprising receiving a read request, corresponding to the first product assembly data, from a user, and sending a read ticket, corresponding to the first product assembly data, to the user.

7. A server data processing system connected to communicate with a file server cache (FSC) data processing system, comprising:

a processor;

an accessible storage device storing a policy database; and

a network adapter connected to communicate with the FSC, the server data processing system configured to

receive a first pre-caching rule from the policy database;

receive first product assembly data corresponding to the first pre-caching rule, the first product assembly data corresponding to a first subassembly of a product;

transmit the first product assembly data to the FSC to be pre-cached on the FSC according to the first pre-caching rule, wherein the first pre-caching rule includes a scheduling rule specifying when the first product assembly data is to be pre-cached on the FSC and specifying that when the user requests the first product assembly data, then third product assembly data, corresponding to a second subassembly of the product and part of a common bill-of-materials data structure as the first product assembly data, should be transmitted to the FSC to be pre-cached on the FSC; and

transmit the third product assembly data to the FSC to be pre-cached on the FSC according to the first pre-caching rule.

8. The server data processing system of claim 7, wherein the first pre-caching rule defines the first product assembly data to be pre-cached at the FSC without waiting for a request from a user or other system.

9. The server data processing system of claim 7, further configured to

receive a request for second product assembly data from the FSC;

receive a second pre-caching rule from the policy database, the second pre-caching rule specifying that the third product assembly data should be pre-cached on the FSC when the second product assembly data is requested;

receive the second product assembly data and the third product assembly data; and

transmit the second product assembly data and the third product assembly data to the FSC.

10. The server data processing system of claim 9, wherein the second product assembly data and the third product assembly data is product lifecycle management data including multiple product options and variants.

11. The server data processing system of claim 9, wherein the second product assembly data corresponds to a bill-of-materials (BOM) subassembly, and the third data corresponds to a related BOM subassembly.

12. The server data processing system of claim 7, further configured to receive a read request, corresponding to the first product assembly data, from a user, and send a read ticket, corresponding to the first product assembly data, to the user.

13. A non-transitory computer-readable medium storing computer-executable instructions that, when executed, cause a server data processing system to perform the steps of:

receiving a first pre-caching rule from a policy database;

receiving first product assembly data corresponding to the first pre-caching rule, the first product assembly data corresponding to a first subassembly of a product;

transmitting the first third product assembly data to the FSC to be pre-cached on the FSC according to the first pre-caching rule, wherein the first pre-caching rule includes a scheduling rule specifying when the first product assembly data is to be pre-cached on the FSC and specifying that when the user requests the first product assembly data, then third product assembly data, corresponding to a second subassembly of the product and part of a common bill-of-materials data structure as the first product assembly data, should be transmitted to the FSC to be pre-cached on the FSC; and

transmit the third product assembly data to the FSC to be pre-cached on the FSC according to the first pre-caching rule.

14. The computer readable medium of claim 13, wherein the first pre-caching rule defines the first product assembly data to be pre-cached at the FSC without waiting for a request from a user or other system.

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

receiving a request for second product assembly data from the FSC;

receiving a second pre-caching rule from the policy database, the second pre-caching rule specifying that the third product assembly data should be pre-cached on the FSC when the second data is requested;

receiving the second product assembly data and the third product assembly data; and

transmitting the second product assembly data and the third product assembly data to the FSC.

16. The computer readable medium of claim 15, wherein the second product assembly data and the third product assembly data is product lifecycle management data including multiple product options and variants.

17. The computer readable medium of claim 15, wherein the second product assembly data corresponds to a bill-of-materials (BOM) subassembly, and the third product assembly data corresponds to a related BOM subassembly.

18. The computer readable medium of claim 13, further comprising receiving a read request, corresponding to the first product assembly data, from a user, and sending a read ticket, corresponding to the first product assembly data, to the user.
