Atomic transaction over non-persistent protocol(s)

1. A method comprising:

providing to a server a request for server transaction processing, the request being a session request of an outer non-persistent session between a client and the server, the outer non-persistent session comprising the session request provided to the server, the session request to initiate the outer non-persistent session, and a session response by the server, the session response to terminate the outer non-persistent session;

for each inner non-persistent session of one or more inner non-persistent sessions between the client and the server performed as part of a server transaction processed in a plurality of transaction portions:

receiving a session request, from the server, that initiates the respective inner non-persistent session and provides a response to a client request to process a corresponding first transaction portion of the plurality of transaction portions; and

providing a session response to the server that terminates the respective inner non-persistent session and provides a client request to process a corresponding second transaction portion of the plurality of transaction portions; and

receiving, based on termination of a final inner non-persistent session of the one or more inner non-persistent sessions, from the server the session response of the outer non-persistent session to terminate the outer non-persistent session.

2. The method of claim 1 , wherein the outer non-persistent session comprises communication between the client and the server using a first non-persistent communication protocol, and at least one inner non-persistent session of the one or more inner non-persistent sessions comprises communication between the client and the server using a second non-persistent communication protocol.

3. The method of claim 2 , wherein the first non-persistent communication protocol and the second non-persistent communication protocol are a same non-persistent communication protocol.

4. The method of claim 2 , wherein the first non-persistent communication protocol and the second non-persistent communication protocol are different non-persistent communication protocols.

5. The method of claim 2 , wherein the first non-persistent communication protocol comprises Hypertext Transfer Protocol (HTTP) or the second non-persistent communication protocol comprises Hypertext Transfer Protocol (HTTP).

6. The method of claim 1 , wherein the session response of the final inner non-persistent session provides the client request to process the corresponding second transaction portion of the plurality of transaction portions, and wherein the session response of the outer non-persistent session provides a response to the client request to process the corresponding second transaction portion.

7. The method of claim 6 , wherein the session response of the final inner non-persistent session comprises a client commit request for the transaction or client rollback request for the transaction, and wherein the received session response of the outer non-persistent session comprises an acknowledgement of a commit of the transaction or a rollback of the transaction.

8. The method of claim 1 , further comprising providing to the server a token as part of the session request of the outer non-persistent session, and receiving the token from the server with each session request of the one or more inner non-persistent sessions to facilitate correlation of each session request of the one or more inner non-persistent sessions to the outer non-persistent session.

9. The method of claim 1 , wherein transaction processing of the transaction remains open while any of the one or more inner non-persistent sessions remains open.

10. The method of claim 1 , wherein each session response, of the one or more inner non-persistent sessions, provided to the server comprises a client request to execute one or more user programs on the server as part of the server transaction.

11. A computer system comprising:

a memory; and

a processor in communication with the memory, wherein the computer system is configured to perform a method, the method comprising:

providing to a server a request for server transaction processing, the request being a session request of an outer non-persistent session between a client and the server, the outer non-persistent session comprising the session request provided to the server, the session request to initiate the outer non-persistent session, and a session response by the server, the session response to terminate the outer non-persistent session;

for each inner non-persistent session of one or more inner non-persistent sessions between the client and the server performed as part of a server transaction processed in a plurality of transaction portions:

receiving a session request, from the server, that initiates the respective inner non-persistent session and provides a response to a client request to process a corresponding first transaction portion of the plurality of transaction portions; and

providing a session response to the server that terminates the respective inner non-persistent session and provides a client request to process a corresponding second transaction portion of the plurality of transaction portions; and

receiving, based on termination of a final inner non-persistent session of the one or more inner non-persistent sessions, from the server the session response of the outer non-persistent session to terminate the outer non-persistent session.

12. The computer system of claim 11 , wherein the outer non-persistent session comprises communication between the client and the server using Hypertext Transfer Protocol (HTTP) or at least one inner non-persistent session of the one or more inner non-persistent sessions comprises communication between the client and the server using Hypertext Transfer Protocol (HTTP).

13. The computer system of claim 11 , wherein the session response of the final inner non-persistent session provides the client request to process the corresponding second transaction portion of the plurality of transaction portions, and wherein the session response of the outer non-persistent session provides a response to the client request to process the corresponding second transaction portion.

14. The computer system of claim 11 , wherein the method further comprises providing to the server a token as part of the session request of the outer non-persistent session, and receiving the token from the server with each session request of the one or more inner non-persistent sessions to facilitate correlation of each session request of the one or more inner non-persistent sessions to the outer non-persistent session.

15. The computer system of claim 11 , wherein each session response, of the one or more inner non-persistent sessions, provided to the server comprises a client request to execute one or more user programs on the server as part of the server transaction.

16. A computer program product comprising:

a non-transitory computer readable storage medium storing instructions for execution to perform a method comprising:

providing to a server a request for server transaction processing, the request being a session request of an outer non-persistent session between a client and the server, the outer non-persistent session comprising the session request provided to the server, the session request to initiate the outer non-persistent session, and a session response by the server, the session response to terminate the outer non-persistent session;

for each inner non-persistent session of one or more inner non-persistent sessions between the client and the server performed as part of a server transaction processed in a plurality of transaction portions:

receiving a session request, from the server, that initiates the respective inner non-persistent session and provides a response to a client request to process a corresponding first transaction portion of the plurality of transaction portions; and

providing a session response to the server that terminates the respective inner non-persistent session and provides a client request to process a corresponding second transaction portion of the plurality of transaction portions; and

receiving, based on termination of a final inner non-persistent session of the one or more inner non-persistent sessions, from the server the session response of the outer non-persistent session to terminate the outer non-persistent session.

17. The computer program product of claim 16 , wherein the outer non-persistent session comprises communication between the client and the server using Hypertext Transfer Protocol (HTTP) or at least one inner non-persistent session of the one or more inner non-persistent sessions comprises communication between the client and the server using Hypertext Transfer Protocol (HTTP).

18. The computer program product of claim 16 , wherein the session response of the final inner non-persistent session provides the client request to process the corresponding second transaction portion of the plurality of transaction portions, and wherein the session response of the outer non-persistent session provides a response to the client request to process the corresponding second transaction portion.

19. The computer program product of claim 16 , wherein the method further comprises providing to the server a token as part of the session request of the outer non-persistent session, and receiving the token from the server with each session request of the one or more inner non-persistent sessions to facilitate correlation of each session request of the one or more inner non-persistent sessions to the outer non-persistent session.

20. The computer program product of claim 16 , wherein each session response, of the one or more inner non-persistent sessions, provided to the server comprises a client request to execute one or more user programs on the server as part of the server transaction.
