摘要： Managing a log-full condition of a transaction log in a transaction processing system, where the transaction log has a plurality of log records each associated with a particular transaction. When a log-full condition is detected, the active transaction having the oldest log entry of all active transactions is identified and logging for all transactions except for the identified transaction is temporarily suspended. A dynamic transaction backout of the identified transaction is initiated, with the writing of a backout record for the identified transaction to the log being delayed. Confirmation that the backout has completed is awaited before trimming the log. Then the delayed backout record for the identified transaction is written to the log, and normal logging is resumed.

摘要： A transaction processing system comprising a transaction log, a log management policy, a profile and a log manager, and method for managing the transaction log are provided. The method comprises maintaining a transaction log of recoverable changes made by transaction processing tasks, each task having an associated transaction type; storing a log management policy including at least one log threshold and a plurality of possible actions associated therewith; and storing a profile of log resource usage characteristics of tasks for different types of transactions. Usage of the log by transaction processing tasks is monitored to determine when a log threshold is reached. The profile indicates the normal logging behaviour of particular types of transaction by identifying ranges of acceptable values for a plurality of log resource usage characteristics. Such characteristics may include time taken for a task to complete, CPU resource consumed, number of log records made, etc. From a comparison of the profile behaviour with the current log resource usage of a task which has been identified as holding up trimming of the log, likelihood that the identified task having entered an invalid loop and represents a ‘bad’ program, rather than simply validly taking a long time to complete can be inferred. Thus the most appropriate action can be selected and taken.

摘要： To generate a recovery time estimate in a transaction environment, a system includes a recovery manager, a recovery file containing recovery data, a store of historical restart data, and a recovery time estimation component. The recovery manager includes a component which is operable to measure the volume of active data on the recovery file, and to generate a recovery time estimate based on the measured volume and the historical restart data. This recovery time estimate can then be used as a characteristic of the system's keypointing policy to provide a more flexible and efficient keypointing procedure.
