Abstract: Arrangements described herein relate to performing diagnostic tracing of an executing application. A trace entry in trace data can be identified, the trace entry comprising a pointer that refers to a memory address. Whether a value that is, or has been, stored at the memory address is an erroneous value can be determined. Responsive to determining that the value that is, or has been, stored at the memory address is an erroneous value, the pointer can be indicated as being a suspicious value.

Abstract: 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 behavior 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.
