摘要： 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.
摘要翻译：总而言之，本发明是具有多个终端用户终端和多个松散耦合的服务器计算机的分布式计算机系统，其彼此不共享资源。多个用户应用程序进程分布在服务器计算机上。通信接口或路由器在最终用户终端与在一个服务器计算机上执行的事务路由器进程之间传送数据。交易路由器进程基于从终端用户终端接收到的数据，发起用户应用进程的事务的执行。链路管理器进程基于计算负载分配准则选择应用进程来执行应用，以便在服务器计算机上尽可能均匀地分布计算负载，从而最大化系统的吞吐量和响应能力。位于至少一个所述服务器计算机上的文件系统提供对所有用户应用进程的存储的文件和数据库表的访问，而不管每个这样的用户应用程序处理哪个服务器计算机被执行。事务路由器进程包括用于指示等待启动的事务的数据结构，并且当满足关联的启动条件并且可用用户事务处理时，用户应用进程中的一个进行等待事务的执行。

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A transaction processing system manages an information collection by employing a two-phase transaction commit protocol. Transaction participants are provided a unique identifier for use in communicating with the transaction management facility in a distributed environment. If the participant is lost, a backup participant is created, and provided with the same identifier as the failed participant to carry on with the transaction in place of the failed participant.
