WMQ subsystems tuning
EPV for WMQ Critical Events provides a complete vision of the “health” condition of all WMQ subsystems by collecting a set of measures such as storage contractions, logging delays, rollbacks, excessive checkpoints, buffer pool saturation, Coupling Facility structures and SMDS saturation…

EPV for WMQ Resources analyses the amount of system resources (CPU, storage, virtual storage) used by WMQ Address Spaces (Master and Chin), logging activity, checkpoints, Buffer Pool hit ratios and I/O rates, Coupling Facility structures and SMDS activity…

WMQ applications tuning
EPV for WMQ Workload provides complete control of all the workloads connecting to each WMQ subsystem. Utilizing extensive drill-down capabilities, you can explore workload performance and consumptions by connection type, connection name and transaction.
Using EPV for WMQ Workload you can easily eliminate loops and abnormal behaviours, check balancing and perform more effective application tuning activities.

WMQ day by day and proactive tuning
EPV for WMQ Trends provides daily and monthly critical events, resources, throughput and workload trends.
Daily trends will be a key element in day by day tuning activities. By EPV provided functions you can easily compare one day to another and spot anomalies in just few mouse clicks.
Monthly trends will assist you in adopting a proactive approach and understand long term tendencies before they can impact your WMQ subsystems performance.
EPV for WMQ also audits Queue Manager parameters and other subsystem definition changes.

Access to available data
EPV for WMQ uses standard measures normally available in the z/OS environments and supports various sources, such as ITRM (IT Resource Management), MXG (Merrill’s eXpanded Guide) or native SMF data.

Using “de facto” Standard Technologies
All reports are produced in simple static HTML pages published on a server of your choice and can be accessed by your favourite “browser”. All the tables provided in the reports can be exported individually or together in a MS-Excel spread sheet.

Architecture
EPV for WMQ architecture is based on the following three layers:
• An interface to collect input data
• An engine to correlate and aggregate data
• An engine to produce HTML pages.
The interface to collect input data is designed to optimize performance and consumptions of the loading phase, avoiding duplication or loss of data. It uses simple exits that adapt the product to the environment characteristics; a set of ready exits for each data type to acquire is provided.

The engine to correlate and aggregate data builds a standard SAS or SQL relational Data Base, containing only those metrics used by the product and automatically aggregated at the monthly, daily and hourly level. You can customize the product by setting the appropriate parameters and values to keep in your EPV Performance Data Base the desired time periods.

The engine to produce the HTML pages can be customized to:
• Report daily resource and workload statistics for any desired period
• Report daily and monthly trends for any desired period
• and much more…

Requirements
EPV for WMQ is available in two modes: standard or Plus.

The requirements for EPV for WMQ are:
• Availability of a SAS System Base module at least on a PC
• Availability of one of the following products: SAS ITRM, MXG.

EPV for WMQ Plus has no pre-requisites; it’s an “out of the box” solution which integrates a light version of the EPV zParser product to interpret the needed SMF records and all the other input data required.
