    • 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.
    • 一种分布式计算机系统,具有多个终端用户终端和多个彼此不共享资源的松散耦合的服务器计算机。 多个用户应用程序进程分布在服务器计算机上。 Enq表存储在第一台服务器计算机上。 Enq表包括Enq记录,每个记录表示锁定的资源。 当任何用户应用进程执行命名特定资源的Enq指令时,如果Enq表不包含特定资源的Enq记录,则会生成Enq记录,并将其存储在表示特定资源的Enq表中。 Enq记录存储在第一台服务器计算机上的相同Enq表中,无论哪台服务器计算机执行Enq指令。 如果Enq表已经包含特定资源的Enq记录,则执行Enq指令的用户应用程序进程的执行被暂停。 当任何用户应用程序执行指定特定资源的Deq指令时,相应的Enq记录(如果有的话)被删除。 此外,对于在同一特定资源上尝试执行Enq指令时暂停的任何用户应用程序进程的恢复执行。

    • 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.
    • 本发明是一种分布式计算机系统,其具有多个终端用户终端和多个彼此不共享资源的松散耦合的服务器计算机。 多个用户应用程序进程分布在服务器计算机上。 临时存储文件存储在第一个服务器计算机上,用于临时存储数据记录的队列。 每个用户应用进程通过在表示指定数据的临时存储文件中生成和存储至少一个TS数据记录来响应指定要存储在指定临时存储队列中的数据的WriteQ TS指令的执行。 每个TS数据记录都有一个主键,指示记录在指定的临时存储队列中的位置。 每个TS数据记录都存储在第一台服务器计算机上的相同临时存储文件中,而不考虑哪个服务器计算机执行WriteQ TS指令。 每个用户应用进程还通过从临时存储文件读取至少一个TS数据记录来响应执行指定要从中检索数据的临时存储队列的ReadQ TS指令。
