In the embodiments of the present invention, terms to be described:
CICS(Customer Information Control System)：
the online transaction management middleware of the host system supports extremely high concurrency, ensures strong consistency of data and is widely used in host software development; it is similar to the small machine WEBSHPERE and open platform Spring; on-line application programs developed based on the CICS are all responsible for hardware resources to be accessed, object consistency, inter-program communication, resource definition, transaction distribution, concurrency control and the like, the application programs only need to pay attention to business logic, the application development efficiency of a host is greatly improved, and the on-line application programs are widely used in banks at present.
Transaction:
all data and state changes processed in a complete transaction unit must keep strict consistency, namely, the result of the transaction is only successful or failed, and recovery is required if the transaction fails.
And (4) rolling back the affairs:
in order to ensure the data consistency in the transaction, if there is a program error, and the error is fatal and cannot be continued, the update of the data and the state made by the previous program should be completely recovered, and the execution of the subsequent program is terminated, and this action is called "transaction rollback".
The CICS, as a transaction middleware, provides commands such as commit, rolback, etc., by which an application program can control the commit or rollback of a transaction unit transaction.
The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the invention.
In order to implement single-point rollback of CICS online transaction, facilitate program maintenance and reuse, reduce code development difficulty and risk, and avoid confusion of processing information and transaction processing logic errors, the present invention provides a single-point rollback method of CICS online transaction, which specifically includes, with reference to fig. 1:
step S100, transaction data is acquired.
And step S200, calling an online application main program and an online application program for processing the transaction data according to the transaction data.
And step S300, executing each level of online application program in sequence to perform transaction processing, integrating the transaction processing result and the processing result information pushed by the next level according to the preset pushing information priority to obtain the processing result information, and pushing the processing result information to the previous level.
Step S400, when pushing to the online application main program, executing the online application main program, and performing transaction processing according to the processing result information pushed by the previous stage, wherein,
if the processing result information is successful, calling a CICS transaction command interface to submit the transaction;
if the processing result information is warning, notifying manual confirmation, and calling a CICS transaction command interface to submit the transaction when the manual authorization confirmation is submitted; when manual authorization rollback is performed, a CICS transaction command interface is called to perform rollback on the transaction;
if the processing result information is failure, a CICS transaction command interface is called to roll back the transaction.
To more clearly explain the single rollback method of CICS online transaction described above, reference is made to the specific embodiment of fig. 2.
Step S100:
and an operator can input transaction data through the front-end service picture, and the transaction data is uploaded to the CICS middleware system.
Step S200:
and the CICS middleware system calls an online application main program and an online application program for processing the transaction data according to the transaction data.
Referring to the embodiment shown in FIG. 2, the CICS online application main program is used to execute the processing logic of the message transaction, and the CICS online application B, CICS online application C is used to execute the specific logic of the message push mechanism.
In this embodiment, the following main program is abbreviated for CICS online application: a main program;
CICS online application program B is abbreviated as: a procedure B;
CICS online application program C is abbreviated as: and C, performing the step.
Step S300:
and sequentially executing each stage of the online application program to perform transaction processing, integrating the transaction processing result and the processing result information pushed by the next stage according to the self transaction processing result and the processing result information pushed by the next stage, and pushing the processing result information to the previous stage.
In this step, the specific message pushing process is as follows:
when the received processing result information pushed by the next level is successful, if the program execution of the program is successful, pushing the processing result information to the previous level to be successful information; if the execution of the program per se generates warning errors or fatal errors, pushing processing result information to the upper level to be warning or failure information;
when the received processing result information pushed by the next level is warning, if the program is successfully executed, pushing the processing result information to the previous level to be the warning information; if the execution of the program per se generates warning errors or fatal errors, pushing processing result information to the upper level to be warning or failure information;
and when the received processing result information pushed by the next level is failure, the interrupt processing process pushes the processing result information to the previous level to be the failure information.
Taking the CICS online transaction flow shown in fig. 2 as an example, the program called by the CICS middleware system includes a main program, a program B, and a program C;
program C is the lowest level program, and the upper level is program B;
the upper stage of the program B is a main program.
When each level of program is executed, the information to be pushed is generated according to the information coding mechanism. When each level of program pushes information to the next level, a preset information pushing mechanism is followed.
It should be noted that, for different transactions, there are generally multiple online applications invoked for processing transaction data, and multiple programs cooperate to complete a transaction. The present embodiment only describes the transaction process of calling the online application main program and the two-level online application programs (program B and program C) for an exemplary frame, wherein the information encoding mechanism and the information pushing mechanism adopted can be extended to the transaction process of more cascade machine application programs, and the details are not repeated herein.
Specifically, after each program is executed, the obtained processing result information includes a transaction code and transaction information; wherein,
the transaction processing code at least comprises a first code, a second code and a third code, wherein the first code represents success, warning or failure, the second code records the name of the program, and the third code is a program marking code and is used by the program in sequence;
the transaction information is a textual annotation to the transaction code.
In this embodiment, a set of information encoding mechanism of "transaction encoding (7-bit code) + transaction information" strictly followed by all programs may be established in a preset manner, where the information encoding mechanism is:
when the online application program is executed correctly, the information of Sppnnnn and transaction processing is returned, wherein the initial letter of S indicates success, the 2-bit pp is the program name, and the 4-bit nnnn is used by the program in sequence to ensure that the operation is not repeated. The literal interpretation of the information code is then returned to the upper level calling program.
When a warning error occurs in the execution of the online application program, if the situation does not need to perform transaction rollback, the transaction rollback information and the transaction processing information are returned, the initials 'W' represent warning, 2 bits 'pp' are the program name, and 4 bits 'nnnn' are used by the program in sequence, so that the situation is ensured not to be repeated. The literal interpretation of the information code is then returned to the upper level calling program.
When a fatal error occurs in the execution of the online application program, the transaction rollback is required under the condition, then the 'Eppnnnnn' and transaction processing information are returned, the initial letter 'E' indicates failure, 2 bits of 'pp' are the program name, and 4 bits of 'nnnn' are sequentially used by the program, so that the condition that the information is not repeated is ensured. The literal interpretation of the information code is then returned to the upper level calling program.
In this embodiment, the push information priority is failure, warning, and success in order from high to low.
Except the main program of the online transaction, other programs do not judge and process the submission and rollback of the transaction uniformly, when the execution of the program is finished or an error occurs, only the transaction processing coding and the transaction processing information are returned to the calling program of the previous level, and the like, and the steps are returned step by step until the main control program of the first level is returned.
Referring to fig. 2, taking the message pushing sequence of the program C, the program B, and the main program as an example:
executing each level of online application program in sequence to perform transaction processing, wherein the program C is the lowest level and has no next level program, and after the execution is completed, the processing result information of the program C includes 3 conditions:
if the processing result is successful, the processing result information pushed to the upper level is: SCCxxxx and transaction information;
if the processing result is warning, the processing result information pushed to the upper level is: wccxxx and transaction information;
if the processing result is failure, the processing result information pushed to the upper level is: ECCxxxx and transaction information.
The processing result information is pushed to the upper level of the program C, i.e., the program B.
The executive program B performs a transaction, combines the transaction result with the processing result information pushed by the program C, and generates the processing result information of the program B itself, where the processing result information of the program B includes 7 cases:
if SCCxxxx is received and the transaction result of program B is successful, the processing result information pushed to the upper level is: SBBxxxx and transaction information;
if SCCxxxx is received and the transaction result of program B is an alert, the processing result information pushed to the upper stage is: WBBxxxx and transaction information;
if SCCxxxx is received and the transaction result of program B is a failure, the processing result information pushed to the upper level is: EBBxxxx and transaction information;
if the WCCxxxx is received and the transaction result of the program B is successful, the processing result information pushed to the upper level is: wccxxx and transaction information;
if WCCxxxx is received and the transaction result of program B is warning, the processing result information pushed to the upper level is: WBBxxxx and transaction information;
if the WCCxxxx is received and the transaction result of the program B is failure, the processing result information pushed to the upper level is: EBBxxxx and transaction information;
if ECCxxxx is received, interrupting the process, and directly pushing the processing result information to the upper level as follows: ECCxxxx and transaction information;
the processing result information is pushed to the upper stage of the program B, i.e., the main program.
Step S400:
and when the information is pushed to the online application main program, executing the online application main program, and performing transaction processing according to the processing result information pushed by the previous stage.
Specifically, in combination with the above embodiment, no matter how the processing procedure of the program C is changed, the final three processing results are 3 cases: success (S), warning (W), or failure (E);
on the other hand, the process result information pushed by the program C and the transaction result of the program B are mainly 3 types of process result information that is finally pushed: success (S), warning (W), or failure (E); where differences in program names in the transaction code may occur.
In contrast, the main program performs different transactions according to 3 cases:
if the processing result information is successful (S), calling a CICS transaction command interface, submitting the transaction and returning success information;
if the processing result information is warning (W), notifying manual confirmation, and calling a CICS transaction command interface to submit the transaction when the manual confirmation is authorized to submit; when manual authorization rollback is performed, a CICS transaction command interface is called to perform rollback on the transaction;
and if the processing result information is failure (E), calling a CICS transaction command interface, rolling back the transaction and returning failure information.
Through the process, the rollback processing of the transaction is carried out on the online application main program, so that all logics which have errors and need data rollback in the CICS online transaction can be concentrated on one point of the main control program, the program can be maintained and reused conveniently, and the code development difficulty and risk are reduced. In order to realize single-point rollback, a message pushing mechanism and priority pushing logic are set in the scheme, so that the multi-level calling program processing information can be reasonably and effectively pushed to the main program step by step and cannot be covered by errors, and confusion of the processing information and business processing logic errors are avoided.
