XMLMODEL

Syntax

Syntax explanations

XMLMODEL can be created in the following ways:

• PGSCL—Using information about Service Classes from type 72 records and creating an XML model according to the WKL definition commands.
• REPORT—Using only information about Report Classes from type 72 records and creating a simplified CPU sizing model.
• SUITE or APPL—Using information about individual address spaces from type 30 SMF records and creating an XML model according to the SUITE definition commands.
• NONE—Not creating an XML model.

Rules

• Report Classes are used to obtain a small set of measurements, such as CPU utilization, transaction rates, and report times, for certain jobs and started tasks, which are combined into a single Service Class.
• By default, UIE does not use information about Report Classes to create the XML files that contain the baseline configuration and performance data. UIE uses only Service Class data.
• Some vital information is not present in RMF/SMF records for Report Classes, for example, priority distribution and I/O activity distribution by device. Therefore, BMC Performance Predictor for Mainframes cannot calculate the important components of response time (that is, CPU queuing time, I/O service time, and so on) and cannot predict response time in 'What if...?' scenarios. BMC Performance Predictor for Mainframes can only perform sizing, that is, calculating the total amount of MIPs consumed by Report Class and grow it proportionally to transaction rate growth in 'What if...?' scenarios.

• If you still want to create XML files using Report Classes, you should use the command:

  XMLMODEL TYPE=REPORT

  This command has a global effect. Report Classes will be used for all systems and intervals.

• The XML model is always created with the same GMT offset as the Visualizer file. If the GMTOFF parameter is specified in the VISFILE command, the same offset is used in the XML model. If the GMTOFF parameter is not specified in the VISFILE command, but is specified in the SDATE command, then the specified value is used in the XML model. If the GMTOFF parameter is not specified in either the VISFILE or SDATE commands, then the local GMT offset of the system on which UIE is running is used.

Examples

In this example, you are specifying that the XML model will contain SUITES. This command also enables you to use Report Classes for BMC Performance Predictor for Mainframes.

SUITEs are groups of address spaces. The SUITE command allows you to use Report Class Name as one of the selection criteria for address spaces that will be included in the SUITE. In this case, the created XML model contains all the detailed information including I/O distribution and priority distribution. For more information, see details about SUITE.
