IMS Performance Analyzer for z/OS

IMS Performance Analyzer provides a wide variety of performance, usage and availability reports. IMS Performance Analyzer has become the standard for IMS resource and performance management and can help:

• Analyze transaction response time

• Measure the usage and availability of important resources; including databases, programs, regions, buffers (including database), and queues (message and other internal queues)

• Plan for the operational management of IMS, including the scheduling of database re-orgs, monitoring adherence to service levels, charge-back accounting, and capacity planning

• Monitor significant system events like System and Batch Messaging Program (BMP) checkpoints and deadlocks that can adversely affect system performance and availability

• Boost system and application programmer productivity

• Report critical performance information at the required level of detail; from high level management summaries and graphical reports to detailed traces for in-depth analysis

• Analyze the impact of IMS Connect on transaction performance

IMS Performance Analyzer for z/OS, V4.2 provides significant enhancements improving functionality and usability of the product which include:

• New and improved transaction transit reports

• Improved processing efficiency and problem determination by creating the transaction Index record for each IMS transaction

• Consolidated IMS Connect and IMS log transit reporting

• OMEGAMON TRF form-based transit reporting including full transaction accounting, as well as DLI and DB2 call trace and summary

• Enhancements to several existing log reports

• Enhanced DBRC Log selection to use the DBRC RECON API and to optionally select OLDS data sets

• IMSPLEX authorization

In addition to the existing transit reports, a suite of form-based transit reports provide the ability to customize report content and format. With this you can:

• Use Report Forms to tailor the contents of transit reports to include only required metrics or summarize information according to your requirements
• Design your own transit reports using the Report Forms editor (no programming required)
• Create form-based extracts and export to DB2
• Request any number of 30 different form-based reports in a single job run
• Use form-based transit reports for IMS log, IMS Connect, and OMEGAMON TRF reporting
• Use IMS log transaction transit reporting to provide:
  • More accurate transit times by exploiting additional log record types
  • Microsecond precision for all elapsed times
  • Additional transit performance indicators and resource usage metrics
  • Improved distribution reporting as an alternative to peak percentiles and to monitor service levels
  • Enhanced Fast Path reporting

Consolidated IMS Connect and IMS log transit reporting - The reporting for IMS Connect Extensions for z/OS (5655-S56) Event data now provides end-to-end IMS Connect and IMS log reporting. The Connect Transit reports provide a complete picture of the lifecycle of transactions as they pass through IMS Connect and IMS.

• View Connect event latencies and IMS transaction processing metrics including queue times, CPU, and database resource usage statistics in a single report

• Report Forms allow you to tailor the contents of Connect transit reports to include only required metrics or summarize information according to your requirements

• The Connect Event Trace can include IMS Connect and IMS Log records in a single report, providing a complete end-to-end transaction lifecycle picture

Enhanced log reporting - Enhancements to IMS Performance Analyzer log reports include:

• Transaction Resource Usage report orders by Program name for DBCTL

• Database Update Activity report optionally orders by Database and Program

• Message Queue Utilization report optionally shows only enqueued messages

• Fast Path Buffer Usage report substitutes job name for routing code for BMPs

• Deadlock Summary report enhanced to more levels of detail

• System Checkpoint report provides a distribution of checkpoint activity

• Internal Resource Usage reports include Virtual Storage Usage, IMODULE Statistics, EWLM Statistics, 64-bit Cache Storage Manager, and 64-bit Fast Path Buffer Manager statistics

• Cold start analysis report provides a point-in-time snapshot of in-train activity, helpful in the event of a cold start

• Gap analysis report identifies periods of time where log records are not being cut, potentially highlighting an external system event that may have caused IMS to slow down

• MSC Link Statistics report provides send and receive message activity and I/O time analysis

• Transaction Index contains a record for each IMS transaction that accumulates all information from the IMS log about that transaction

Enhanced monitor reporting - IMS Performance Analyzer monitor reports include options to exclude BMPs from reporting or include only BMPs. Comprehensive IMS monitor reporting includes Fast Path and the new Synchronous call-out elapsed time analysis.

OMEGAMON TRF reporting - IBM Tivoli OMEGAMON XE for IMS Transaction Recording Facility (TRF) collects detailed transaction accounting, performance and resource utilization information for IMS transactions. IMS Performance Analyzer provides a suite of form-based transit reports to analyze this data.

DBRC Log Selection provides the following new enhancements:

• Use of the DBRC RECON API in place of the DBRC utility DSPURX00

• Optional selection of OLDS data sets when no SLDS data sets are available for up-to-date report requests

• Uses the READONLY API option (IMS V10 or later) - users now require only read access to the RECON data sets

• IMSPLEX authorization exit to prevent accidental disabling of the RECON data sets

• Optionally use secondary SLDS files, to relieve availability contraint on primary copies

• Support for the DBRCGRP parameter

• Connect file selection supports active journals, for when a report request needs recent data not yet archived

ISPF dialog enhancements include support for:

• New Report Forms allowing you to tailor the format of Transit reports to suit your personal reporting requirements
• Including Connect systems in groups to allow combined IMS Connect and Log reporting
• IMS system definitions specifying OMEGAMON TRF Extractor files in addition to IMS Log and Monitor data sets
• Log Report Set providing a suite of new form-based transit reports
• Connect Report Set providing a suite of new form-based transit reports and the ability to combine Connect and IMS log information in a single report
• TRF Report Set providing form-based transit reporting from OMEGAMON TRF Extractor files to provide detailed IMS transaction accounting statistics, including DLI and DB2 calls
