A computer implemented transaction processing system is presented for processing transactions between an application and one or more transaction processors. The system utilizes a first communication link between the application and a transaction processor interoperability component. Then, the system determines which of the one or more transaction processors will process transactions for the application and establishes a communication link between the transaction processor interoperability component and the transaction processor that will process transactions for the application. Then, as the application transmits a transaction from the application to the transaction processor interoperability component, the transaction is formatted by the transaction processor interoperability component for compatability with the transaction processor that will process transactions for the application, and finally transmitting the formatted transaction to the transaction processor that will process transactions for the application.

Then, as the application transmits a transaction from the application to the transaction processor interoperability component, the transaction is formatted by the transaction processor interoperability component which includes invoke logic to provide a transaction processing user interface which is independent from any specific transaction processing program, but provides a consistent user interface to all transaction processing programs. The invoke logic also provides a request/response and conversational style interaction between the transaction monitor clients and the transaction monitors on the server. The database utilized by the transaction processor monitor leverages a service name and service resolver database to map a service name to transaction monitor specific attributes.

Transactions can be started implicitly utilizing the attributes of the service name in the service resolver database. Transactions can also be terminated implicitly at the appropriate points both for request/response and conversational interoperability.

System and method for processing transactions in an environment

A distributed computer system having a plurality of end user terminals and a plurality of loosely coupled server computers that share no resources with each other. A multiplicity of user application processes are distributed over the server computers. An Enq table is stored on a first one of the server computers. The Enq table includes Enq records, each representing a locked resource. When any user application process executes an Enq instruction naming a specific resource, if the Enq table does not already contain an Enq record for the specific resource an Enq record is generated and stored in the Enq table representing the specific resource as locked. The Enq record is stored in the same Enq table on the first server computer regardless of which server computer executes the Enq instruction. If the Enq table does already contain an Enq record for the specific resource, execution of the user application process that executed the Enq instruction is suspended. When any user application process executes a Deq instruction naming a specific resource, the corresponding Enq record, if any, is deleted. In addition, execution is resumed for any user application process that was suspended when it attempted to execute an Enq instruction on the same specific resource.

Customer information control system and method with transaction

In a coupled data processing system having multiple users, either in a single system or in a multi-system environment, a coupling facility storage structure is used to provide a log management facility. The log management facility provides for a real time physical log merge of the data written into the log stream without interprocessor communication required to process the records in logical sequence. The log management facility supports concurrent write, delete, browse, and asynchronous off-load to dasd processes across multi-users and multi-systems. The log management facility maintains the log records, independent of the log media, in time sequence. A logical block id is assigned to each log record written so that it can be directly accessed at a later time.

Method and system for log management in a coupled data processing system

In summary, the present invention is a distributed computer system having a plurality of end user terminals and a plurality of loosely coupled server computers that share no resources with each other. A multiplicity of user application processes are distributed over the server computers. A communication interface or router transmits data between the end user terminals and a transaction router process, which executes on one of the server computers. The transaction router process initiates execution of transactions by ones of the user application processes based on data received from the end user terminals. A link manager process selects application processes to execute the applications based on computational load distribution criteria, so as to distribute computational load as evenly as possible over the server computers, thereby maximizing the throughput and responsiveness of the system. A file system, located on at least one of said server computers, provides access to stored files and database tables to all of the user application processes without regard to which server computer each such user application processes is executed on. The transaction router process includes a data structure for indicating transactions waiting to start and for initiating execution of ones of the waiting transactions by ones of the user application processes when associated start criteria are satisfied and user transaction processes are available.

Customer information control system and method in a loosely coupled

The present invention is a distributed computer system having a plurality of end user terminals and a plurality of loosely coupled server computers that share no resources with each other. A multiplicity of user application processes are distributed over the server computers. A temporary storage file is stored on a first one of the server computers, for temporarily storing queues of data records. Each user application process responds to execution of a WriteQ TS instruction specifying data to be stored in a specified temporary storage queue by generating and storing at least one TS data record in the temporary storage file representing the specified data. Each TS data record has a primary key indicating the record's position in the specified temporary storage queue. Each TS data record is stored in the same temporary storage file on the first server computer regardless of which server computer executes the WriteQ TS instruction. Each user application process also responds to execution of a ReadQ TS instruction specifying a temporary storage queue from which data is to be retrieved, by reading at least one TS data record from the temporary storage file.

Plurality of servers having identical customer information control

The present invention is a distributed computer system having a plurality of end user terminals and a plurality of loosely coupled server computers that share no resources with each other. A multiplicity of user application processes are distributed over the server computers. A transaction start table, stored on a first one of the server computers, stores transaction start data representing transactions whose execution has been requested by other transactions being executed by the user application processes. The transaction start data indicates a start condition for each transaction whose execution has been requested. For most requested transactions the start condition is a time value indicating an earliest time at which the requested transaction's execution should be started. When any of the user application processes executes a Start transaction function, a transaction start record is generated and stored in the transaction start table. The transaction start record is stored in the same transaction start table on the first server computer regardless of which server computer executes the Start transaction function. A transaction start process evaluates the start condition for each transaction whose execution has been requested. When the start condition for a requested transaction is satisfied, the transaction start process initiates execution of that requested transaction.
