Appl. No.:

12/837537

Max Douglas Smith - Tucson AZ, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 9/44

US Classification:

717128, 717127, 717131

Abstract:

Method, system, and computer program product embodiments of a time-based trace facility for facilitating software debugging without interfering with the run-time behavior, performance or resource usage of the traced software are provided. The trace facility resides in a different address space than the target address space and uses different time-slices of CPU resources to execute the instructions in the address spaces. The trace facility uses a cross-memory mode to read the state data from the target address space in accordance with a time schedule. The trace facility writes the state data to a trace area, which may be located in either the target or trace address spaces or external storage. With this approach, the trace facility can read a large amount of state data frequently to construct the type of historical record needed to analysis run-time behavior, performance and resource usage.

International Classification:

G06F 11/00

US Classification:

714 3812

Abstract:

Generation of diagnostic information of a computer-implemented system is made early so that the data is closer to the causation of errors or for performance analysis. At least one selected activity of the system is monitored from initiation of the activity, and the monitoring is for successful completion. Early collection of diagnostic information is provided by comparing the time of the activity without successful completion to an initial trigger, where the initial trigger is less than the time period for a time-out for the activity. If the time of the activity without successful completion exceeds the initial trigger, diagnostic information is collected and an initial dump of the diagnostic information is taken. In one example, a notification that the dump of diagnostic information has been taken is directed to the host or diagnostic terminal.

US Classification:

714 37, 702183

Abstract:

According to one embodiment, a test system includes a data collection module adapted for collecting data from a test system, a storage module adapted for storing the collected data in an organized format, the data including problem data, associated configuration information, associated performance information, and activity data, an analysis module adapted for analyzing the collected data to define at least two activity zones by correlating the problem data, the associated configuration information, the associated performance information, and the activity data, the at least two activity zones including a safe zone where the test system operates normally and a danger zone where the test system is susceptible to operational problems, and an adjustment module adapted for adjusting available resources and/or workload of the test system to cause the test system to operate in the danger zone thereby increasing a likelihood of fault occurrence for testing purposes.

International Classification:

G06F 12/16
G06F 17/30

US Classification:

707640, 707E17005

Abstract:

A method for reducing the data analysis overhead on a production system is disclosed herein. In one embodiment, such a method includes replicating production data from a primary site to a remote site. A control data set containing information for directing analysis of the production data is generated at the primary site and replicated to the remote site. At the remote site, the method includes analyzing the production data as directed by the control data set by making use of time on a CPU located at the remote site. Analysis may involve executing a diagnostic routine and/or generating a log file documenting the results of the analysis. A corresponding apparatus, system, and computer program product are also disclosed and claimed herein.

International Classification:

G06F 17/30

US Classification:

707752, 707E17044

Abstract:

An approach to efficient data reorganization. The approach may involve searching for control interval (CI) splits and control area (CA) splits in a data component of a VSAM data set. A mapping is created that maps the source location storing the VSAM data set to a target location. The mapping reorders the VSAM data set such that the CI splits and CA splits are removed when the VSAM data set is moved to the target location in accordance with the mapping. Those CAs that do not include CI splits may be moved without using the host devices' processing resources. For example, the storage device may FlashCopy these areas directly from the source location to the target location. Those CAs that do include CI splits may be moved using the host's processing resources. For example, these CAs may be read into the host, re-ordered by the host, and written by the host to the target location.

International Classification:

G06F 9/44

US Classification:

717128

Abstract:

An approach to selectively recording trace data. The approach sifts through process control and state data to store data that is most relevant to aiding debugging while reducing the overall amount of data that is stored in a trace data set by a trace facility. The approach may involve initiating a trace operation for the software component and, for each resource of the software component, determining whether the resource is currently in use. For those resources in use, the current state of the resource is compared with the previous state of the resource. If the current state has changed, the current state is written to the trace data set. If the resource is not in use, or the current state has not changed, no entry is made to the trace data set. The approach may also analyze users to determine which resources the users are holding and/or waiting for.

International Classification:

G06F 3/06

Abstract:

Provided are a computer program product, system, and method for processing a write of records to maintain atomicity for writing a defined group of records to multiple tracks. A write is received comprising defined groups of records to write to a plurality of tracks in the primary storage system. Sub-writes are generated to write the records in the defined groups in the write. At least one of the sub-writes includes records to write for at least one of the defined groups that spans multiple tracks in response to determining that at least one of the defined groups includes records that will be written to multiple tracks. The sub-writes are transmitted to the primary storage system to mirror to the secondary storage system to cause the secondary storage system to return complete in response to completing writing to all the tracks written to by the sub-write.
