Transaction log management

A transaction processing system comprising:

• a transaction log for recording recoverable changes made by transaction processing tasks;
• log management policy including a log threshold and a plurality of possible actions associated therewith;
• a profiler for generating a historical profile comprising a set of acceptable values for characteristics of the log resource usage of tasks;
• a log manager for monitoring usage of the log by transaction processing tasks and determining when the log threshold is reached;
• and operable, in response to determining that the log threshold has been reached, to:
• identify an active task having the oldest log entry of all active tasks;
• compare a value of a characteristic of the identified task to the set of acceptable values identified in the historical profile for a corresponding characteristic;
• select, in dependence on the comparison, one of the plurality of possible actions associated with the threshold reached;
• and
• request the selected action.

A computer program element comprising computer program code to, when loaded into a computer system and executed by a processor thereon, cause the computer to perform the steps of:

• maintaining a transaction log of recoverable changes made by transaction processing tasks;
• storing a log management policy including a log threshold and a plurality of possible actions associated therewith;
• generating a historical profile comprising a set of acceptable values for characteristics of the log resource usage of tasks;
• monitoring current usage of the log by transaction processing tasks to determine when the log threshold is reached;
• and
• in response to determining that the log threshold has been reached:
• identifying an active task having the oldest log entry of all active tasks;
• comparing a value of a characteristic of the identified task to the set of acceptable values identified in the profile for a corresponding characteristic;
• selecting, in dependence on the comparison, one of the plurality of possible actions associated with the threshold reached;
• and
• taking the selected action.
