摘要： An improved method, apparatus, and computer instructions for generating trace data. In response to detecting a trace event, a determination is made as to whether identifiers for the trace event match recorded identifiers for a record in a set of previously recorded trace events. Location information for the record is placed in the trace data if a match between identifiers for the trace event and recorded identifiers for the record in the set of previously recorded trace events.

摘要： An improved method, apparatus, and computer instructions for generating trace data. In response to detecting a new trace event, a determination is made as to whether the new trace event occurred at an expected period of time with respect to a prior trace event. A time stamp in the trace data is placed in response to a determination that the new trace event did not occur at the expected period of time, wherein time stamps occurring at the expected period if time are eliminated from the trace data and wherein compression of the trace data occurs.

摘要： A program is profiled with enablement of trace record generation during a first period of time and with disablement of trace record generation during a second period of time. The number of trace records output during the first period of time is determined, and a trace overhead calibration value is computed as an average time for writing the number of trace records output during the first period of time. The trace overhead calibration value may be stored for subsequent use in a profiling-related process in the data processing system. The trace overhead compensation value represents the amount of time required to generate a trace record, and the trace times retrieved from the trace records are adjusted to compensate for the amount of time required to generate those trace records.

摘要： A method and system are disclosed for operating an object-oriented environment within a computer system. The execution of the object-oriented environment is initiated. A first memory location is allocated in a memory area within the object-oriented environment for storing an object. A second memory location is allocated in the memory area with the allocation of the first memory location for storing a persistence indicator. The persistence indicator indicates a point during the execution of the object-oriented environment at which the allocation of the first memory location occurred. A total number of bytes of the memory area which had been allocated during the execution of the object-oriented environment when the allocation of the first memory location occurred is stored as the persistence indicator.

摘要： A method and system for tracing profiling information using per thread metric variables with reused kernel threads is disclosed. In one embodiment kernel thread level metrics are stored by the operating system kernel. A profiler request metric information for the operating system kernel in response to an event. After the kernel thread level metrics are read by the operating system for a profiler, their values are reset to zero by the operating system kernel. The profiler then applies the metric values to base metric values to appropriate Java threads that are stored in nodes in a tree structure base on the type of event and whether or not the kernel thread has been reused. In another embodiment non-zero values of thread level metrics are entered on a liked list. In response to a request from a profiler, the operating system kernel reads each kernel thread's entry in the linked list and zeros each entry. The profiler can then update the intermediate full tree snapshots of profiling information with the collection of non-zero metric variables.

摘要： A user may specify a vector of metrics to be used while profiling a program. The vector of metrics may optionally be thread-relative. In response to a notification of an occurrence of the current event, a thread-relative elapsed metric is computed by: determining a current thread; retrieving a stored reference metric for the preceding event of the current thread; obtaining a current reference metric; and computing the thread-relative elapsed metric as a difference between the current reference metric and the stored reference metric. In order to prevent the generation of redundant metric information, the information associated with the vector of metrics maybe placed into the trace records in several different space-saving formats.

摘要： A method and system for detecting and recovering from errors in trace data is provided. The trace data records selected events for executing routines, and the routines corresponding to the events are represented as one or more nodes in a tree structure. The events may be entries and exits to executing methods. A trace record identifying a routine is read, and an error condition is detected in which the identified routine does not match a routine corresponding to a current node in the tree structure. The tree structure is searched for a node that corresponds to the identified routine. Performance statistics, such as execution time, are attributed to nodes in the tree structure. In response to a determination that the current node is a root node of the tree structure, then a new node for the identified routine is added to the tree structure as a child node of the root node and spliced into the tree at the root node.
