摘要： Methods, systems and program products for log-shipping data replication from a primary system to a communicatively-coupled standby system. Embodiments of the invention may receive transactional log data at a standby system, from the primary system, and before the transactional log data is written to storage on the primary system. Embodiments may then receive a notification from the primary system indicating that the corresponding log data was written to storage on the primary system, and responsive to receiving the notification, may process the received transactional log data.

摘要： A storage manager and related method and computer program product manages client data on a data storage resource and includes the ability to utilize many different types of data stream filters that are neither built into the storage manager nor require a custom programming effort. A storage manager user may readily implement filtering by simply identifying a data stream filter the user wishes the storage manager to use for filtering the user's data. The filter can be an off-the-shelf program that is not part of the storage manager and which does not require client application or storage manager domain knowledge (e.g., knowledge of protocols or data types or formats used by the application or storage manager). The storage manager invokes the identified filter as part of a requested data stream operation and receives a data stream from a data stream source. The data stream is provided to the filter, which filters the data stream. Following filtering, the storage manager receives the data stream from the filter and sends it to a data stream destination.

摘要： Techniques for managing memory buffers include maintaining a pool of buffers and assigning the buffers to buffer classes based on the frequency with which information stored in the buffers is accessed. Different algorithms can be used to manage buffers assigned to the different classes. A determination can be made as to whether a particular buffer qualifies for entry into a particular one of the buffer classes based on a comparison between a threshold value and the frequency with which information stored in the particular buffer was accessed during a specified time interval. Additionally, the threshold value can be adjusted dynamically to take account, for example, of the current load on the system.

摘要： A log-shipping data replication system employs a primary server coupled to a standby server. In operation, the primary server concurrently flushes log data at the primary server and transmits the same log data from the primary server to the standby server. The primary server further transmits at least one buffer flush boundary indication to the standby server indicating the flushing status of the log data at the primary server. The standby server processes the log data as a function of receiving the log data from the primary server, and/or receiving the at least one buffer flush boundary indication from the primary server.

摘要： A method and system are provided for providing a consistent reintegration of a failed primary instance as a new secondary instance with implementation of truncation of log records. Upon failure of a primary instance, a secondary instance may be reassigned as the new primary instance. Prior to reintegration, any portion of the database log of the failed primary that is after the log position of the new primary instance may be truncated, followed by a comparison of the log positions of both the new primary instance and the new secondary instance. In limited circumstances, the truncation of the log data generated by the failed primary instance after the point of failure is possible, and supports reintegration of the failed primary as a new secondary instance with limited overhead.
