摘要： A computing system and method of executing a software program and translation of instructions for an emulated computing environment. The computing system includes a programmable circuit capable of executing native instructions of a first instruction set architecture and incapable of executing non-native instructions of a second instruction set architecture. The emulator operates within an interface layer and translates non-native applications hosted within an emulated operating system for execution. The computing system includes translated memory banks defined at least in part by the emulated operating system and capable of native execution on the programmable circuit, where the emulated operating system is incapable of execution on the programmable circuit. The computing system includes a linker configured to manage association of at least one of the one or more translated memory banks to the interface layer for native execution by the programmable circuit in place of a corresponding bank of non-native instructions.

摘要： Systems and methods for testing and validation of translated memory banks used in an emulated system are disclosed. One method includes translating one or more banks of non-native instructions into one or more banks of native instructions executable in a computing system having a native instruction set architecture. The one or more banks of non-native instructions define one or more tests of execution of a non-native instruction set architecture. The method also includes loading a memory with instructions and data defined according to the non-native instruction set architecture and addressed by the one or more tests, and triggering, by an emulator, execution of the translated one or more banks of native instructions. The method further includes, upon detection of an error during execution of the translated one or more banks of native instructions, identifying an error in execution of the non-native instruction set architecture by the computing system.

摘要： A system and method for providing transaction indivisibility in a transaction processing system through the use of commonly-accessible modules for monitoring and maintaining proper source message sequencing is provided. A source message is transmitted from the host processing unit upon recovery of a failure of the host processing unit, where the source message includes information destined for the database, and an identifying sequence number. The identifying sequence number is compared to a stored sequence number, where the stored sequence number is associated with an immediately preceding source message received prior to the failure of the host processing unit. A source message indivisibility failure is indicated where the identifying sequence number is not consecutive with respect to the stored sequence number, while the source message is added to a message execution queue if the identifying sequence number is consecutive with respect to the stored sequence number.

摘要： Method and apparatus for tracking messages and transactions communicated between a number of users and a number of hosts, where the hosts are executing concurrent applications. During a first user session, a first user communicates with a first host. A counter associated with the first user session is incremented when the application creates an output message. The counter is decremented when the output message is released to the first user. A flag associated with the first user session is set and the counter is incremented once the flag is set, if an input message or committing transaction is received from the first user. The flag is cleared and the counter is decremented when the input message or committing transaction is processed by the concurrent application. The counter being decremented indicates there are no dependencies during the first user session with regard to the output message, input message, or committing transaction. If a second user session is initiated with a second host, the second host determines if there are any dependencies with the first user session. A dependency exists if the output message is created but not released, or if the input message or committing transaction is received but not processed. If there are dependencies, the first user session is reestablished to resolve the dependencies, otherwise, the second session is continued.
摘要翻译： 用于跟踪在多个用户和主机执行并发应用程序的主机之间传递的消息和事务的方法和装置。 在第一用户会话期间，第一用户与第一主机通信。 当应用程序创建输出消息时，与第一用户会话关联的计数器递增。 当输出消息被释放到第一个用户时，计数器递减。 如果从第一用户接收到输入消息或提交事务，则设置与第一用户会话关联的标志，并且一旦设置了标志，则计数器递增。 当并发应用程序处理输入消息或提交事务时，标志被清除，计数器递减。 计数器递减表示在第一个用户会话期间关于输出消息，输入消息或提交事务没有依赖关系。 如果用第二主机发起第二用户会话，则第二主机确定是否存在与第一用户会话有任何依赖关系。 如果输出消息被创建但未被释放，或者输入消息或提交事务被接收但未被处理，则存在依赖关系。 如果有依赖关系，则重新建立第一个用户会话来解析依赖关系，否则第二个会话继续。

摘要： A system and method for balancing database transaction request distribution between various hosts in a multiprocessor transaction processing system is provided. The transaction processing system includes a database and multiple host processors each coupled to at least one database transaction request unit. Database transaction requests sent from the host processors are collectively entered into a commonly-accessible load balancing queue. Each database transaction request is accompanied by a source identifier that identifies the database transaction request unit which initiated the corresponding database transaction request. The queued database transaction requests from the load balancing queue are processed by currently-available host processors, regardless of which host processor initiated the database transaction request. A transaction request acknowledgment for each of the processed transaction requests is created and transferred to the database transaction request unit identified by their respective source identifiers.

摘要： A system and method for organizing and managing recovery information on a per-transaction basis using distinct memory structures is provided. A transaction processing system includes one or more transaction request units for initiating data transactions with a database. A memory architecture includes storage modules to store transaction recovery information that is used in recovering from a transaction processing failure, and further includes transaction descriptor memory structures each of which correspond to a distinct transaction. The transaction descriptors allow access to the transaction recovery information to be isolated from other transaction recovery information. A control information field in each transaction descriptor stores a transaction identifier that identifies the distinct transaction to which it corresponds. The transaction descriptor also includes multiple information address fields, each of which includes a pointer to one of the storage modules that stores part of the transaction recovery information associated with the transaction identifier.

摘要： A transaction processing audit and recovery system is disclosed. After processing a transaction, an audit manager logs in audit records only changed blocks of data of a segment of a database. Upon failure of database backing storage, a prior copy of the database is reloaded to database backing storage that is available and a recovery manager reads the audit records and copies the changed blocks back to the database backing storage. An outboard file cache system is used in conjunction with the recovery manager to recover the database. The outboard file cache provides cache storage for segments of the database and writes non-contiguous blocks of one or more segments as directed in a single input/output request initiated from the recovery manager.

摘要： A system and method for assembling database restoration data according to transaction in a transaction processing system. Database restoration data is collated by chronologically storing updated database records in distinct storage banks partitioned according to its corresponding transaction. Resulting database record blocks from storage banks associated with completed database transactions are queued in the order that their corresponding transactions were completed. The queued database record blocks are transferred to storage media, whereby the queued database record blocks are arranged on the storage media according to transaction, and in the order that the active transactions were completed.
