Therefore, the change of the resident data of being upgraded by the application program 112 of the computing machine 1 with raw data (original) 11 of main memory is reflected in resident data (duplicating) 21 grades of main memory of other all computing machines, in addition, handling request from the item of the application program of computing machine 2 grades with copy data is at first handled by the computing machine 1 with raw data, afterwards, be reflected in all computing machines except that comprising computing machine 2.

Therefore,, do not know the storage of the resident data of original main memory, can realize access yet even from application program.

In addition, it is at first raw data to be carried out at first that the update transaction of copy data is handled, and the result is reflected to so-called unidirectional reflection method on the copy data.

Therefore, the update transaction of the application request of the computing machine of formation dispersant system is handled request and also can be carried out in proper order by acceptance by the computing machine with raw data, because needn't mediate when carrying out, so can realize transaction processing environment at a high speed.

(embodiment 2)

Illustrate that by Fig. 7 and Fig. 8 the item in the local update of primary storage constant data of the present invention handles restoration methods.In addition, Fig. 7 and Fig. 8 are continuous each other.

Two figure are illustrated under the situation of the local update processing of carrying out Fig. 2 and Fig. 3 explanation, handle the method that the recovery item is handled request omission or the order confusion from the item that the momentary fault of network causes.

Among Fig. 7 and Fig. 8, first item handle to be recovered the processing 113,213 of the omission that parts 306 are handled by the item that detects a transaction processing executive part and constructs to omit item and handle processing 114,214 that later item handles and item processing and finish formation 115,215 and constitute.

When the transaction processing executive 16 of computing machine 1 finishes in the item processing execution, the item after carrying out is handled request add in the item processing end formation 115.

Be illustrated in Fig. 2 and Fig. 3 though handle the state of the item processing request of application program 1, not shown here.

Handle request by the item that the transaction processing executive 16 of computing machine 1 is handled, the item of machine 1 is handled the item processing reception program 210 that router 18 sends to computing machine 2 as calculated.

Though handling router 18 from the item of computing machine 1 is undertaken by network to the communication of the item processing request of the item processing reception program 210 of computing machine 2, but because the momentary fault of network, so exist in the possibility of missed events processing request on the network.

In the present embodiment, the item with transaction processing executive additional representation item processing execution order in the item processing request that the resident data of the local main memory of oneself are handled of the resident data computing machine of main memory is handled sequence number.Therefore, can detect omission or order confusion that item is handled request, as the omission of sequence number.

Particularly, handle successional processing because in transaction processing executive, appended the investigation item, handle to produce in the request when omitting when the item of having added sequence number at transaction processing executive 16, detect by the transaction processing executive 26 of computing machine 2 by computing machine 1.

When the transaction processing executive 26 of computing machine 2 detects the omission of item processing request, the item that this content is handled router 28 and computing machine 1 by the item of computing machine 2 is handled the transaction processing executive 16 that reception program 110 is notified to computing machine 1.

When item is handled the omission of request in the transaction processing executive 26 of the transaction processing executive 16 notice computing machines 2 of computing machine 1, finish the later item processing request of taking-up omission item processing the formation 115 from the item processing of computing machine 1, the item processing reception program 210 of the item processing router of process computing machine 1 and computing machine 2 passes to the transaction processing executive of computing machine 2.

Transaction processing executive 16 processing of computing machine 2 are asked from the transaction processing executive 16 item processing that transmit, that omission item processing request is later of computing machine 1.

At first, under the situation that the remote update item that describes with Fig. 4 and Fig. 5 is handled, because what additional things was handled sequence number is the transaction processing executive 16 with the resident data computing machine 1 of original main memory, so the omission that item is handled becomes the transaction processing executive 26 of detection computations machine 2, recovery is afterwards handled, is promptly omitted item and handles the later item of request to handle Request Processing identical with the item processing recovery situation of the local update of Fig. 7 and Fig. 8 explanation.

According to said method, at local update and remote update by the resident data of main memory, in the main memory data management method according to the position of applying for the resident data of hidden main memory, raw data and copy data are being remained in the structure of identical content, even under situation about handling because of the generation missed events of network failure etc., because can handle from the item of omitting and carry out the item processing once more, so raw data and copy data can be remained identical content.
