摘要： A mechanism is provided for replicating non-supported data types using an existing replication format supported by an existing replication system. Responsive to detecting an application writing data to a local storage that is to be replicated to the secondary site, the input/output (I/O) operation being performed by the application is intercepted. Data of the I/O operation in a non-supported format is converted to a format supported by the existing replication system. A replication log record is generated for the data in the format supported by the existing replication system. The data described by the replication log record for the data is then stored in a storage device at the secondary site.

摘要： Tailoring diagnostic information specific to current activity of multiple threads within a computer system. A request to dump system state is received. A system dump is created, including main memory and system state information. The system dump is stored to a database. In response to a request to format the system dump, the system dump is loaded from the database, whereby a virtual memory image of system state at system dump time is created. The virtual memory image and system state information is scanned to identify tasks that were running, tasks that have failed due to an error, and tasks that were suspended at system dump time. State information and control blocks associated with the identified tasks are collected from the system dump and collated based on task number. The database is updated with a formatted system dump, including the state information and control blocks associated with the identified tasks.

摘要： Embodiments of the present invention provide a method, system and computer program product for consistent replication of transactional updates. In an embodiment of the invention, a method for consistent replication of data in a transaction processing system is provided. The method includes recording entries in a replication log of different data updates and corresponding transactions and additionally recording entries in the replication log indicating whether or not the transactions have been backed out. The method also includes replicating only those data updates referenced in the log which do not correspond to transactions indicated in the log to have been backed out. For instance the additionally recorded entries in the replication log indicate when a transaction has been backed out. Alternatively, the additionally recorded entries in the replication log indicate when a transaction has been committed.
摘要翻译：本发明的实施例提供了用于事务更新的一致复制的方法，系统和计算机程序产品。在本发明的实施例中，提供了一种在事务处理系统中数据一致复制的方法。该方法包括在不同数据更新和对应事务的复制日志中记录条目，并在复制日志中另外记录条目，指示事务是否已被备份。该方法还包括仅复制在日志中引用的那些与日志中指示的事务不对应的已被备份的数据更新。例如，复制日志中附加记录的条目指示事务何时被退出。或者，复制日志中附加记录的条目指示事务何时已提交。

摘要： Operating an online transaction processing system to perform an application including a first module call by performing the following steps (not necessarily in the following order): (i) assigning a dedicated search path to the application, where the search path specifies an ordered set of location(s) for searching for module code, the set of location(s) includes at least a first dynamic module library and the first dynamic module library is ahead of any other locations which may be included in the dedicated search path; (ii) running the application through the transaction processing system; (iii) receiving the first module call, from the running of the application, specifying a requested module using a requested module name; and (iv) in response to the module call, locating the requested module based on the requested module name and the dedicated search path.
