Problems solved by technology
[0003] At present, financial institutions use CICS for many products in production. When communicating between CICS, timeout parameters need to be set according to business requirements. In order to avoid long-hanging transactions, technicians usually set timeout parameters in the TD configuration file of CICS through the timeout parameter, but the parameters The minimum unit is set to minutes, and the timeout setting in seconds cannot be realized. For example, the timeout definition of upstream products is 50 seconds. According to the funnel principle, the timeout definition of downstream products cannot be less than 50 seconds, such as 45 seconds. This brings certain impact to the application. limitations

Embodiment Construction
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0032] Although the transaction timeout defined in the CICS system can be configured in RD, the parameter in RD is XPRecvTimeout, and the configuration is applicable to all transactions. Although it can be set to the second level, it is relatively rigid. Once defined, all transactions use the same timeout parameter. If you use the method of defining TD in CICS for configuration, the parameter in TD is Timeout. Although this method can set a personalized timeou...

The present invention provides a method and system for clearing long transactions in the CICS system. The method includes: obtaining the preset monitoring transaction list in the CICS system and the timeout time corresponding to the monitoring transaction list; Transactions, and record the current number of online transactions and online transaction lists each query; compare the two online transaction lists whose query time interval is equal to the timeout time, and determine whether there is the same transaction number; if there are the same Transaction number, judging whether the same transaction number is also on the monitoring transaction list; if the same transaction number is also on the monitoring transaction list, use a clear command to clear the transaction corresponding to the transaction number. By utilizing the embodiment of the present invention, specific transactions that need to be monitored can be flexibly configured, and a specific timeout period can be specified for each transaction, so as to realize system control during upstream and downstream interactions, and effectively ensure the stable operation of each product.
Description
technical field [0001] The invention belongs to the technical field of computers, in particular to a method and system for clearing long transactions in a CICS system. Background technique [0002] CICS is transaction middleware, and its English meaning is Customer Information Control System, that is, customer information control system. CICS is a product that provides online transaction processing and transaction management for applications on IBM and non-IBM platforms. Its function is to provide a transaction processing environment for commercial applications, and it is suitable for systems with a large number of unexpected online events such as banks. CICS is built on the operating system, ISO's Distributed Computing Environment (DCE, Distributed Computing Environment) and Encina services. CICS can be closely integrated with DCE to meet the special requirements of the distributed environment for security and name services. [0003] At present, financial institutions use ...
