With Strobe 18.02 and iStrobe 19.05, Compuware continues to evolve the next generation of Application Performance Management (APM) on z/OS. The purpose of our next generation solution is to enable our customers to proactively identify, understand, and act upon emerging performance problems in order to be successful in achieving their APM goals.
Note: Strobe Release 18.02 requires Enterprise Common Components (ECC) Release 17.02 or more current, with all current maintenance applied . Click the following link for access to ECC current maintenance: https://go.compuware.com/products/cy/fixes/30240.aspx .
The SRB Activity report displays the percentage of CPU time that an SRB--either preemptible SRBs and non-preemptible SRBs--was seen executing in the measured address space during the measurement period ordered by percentage of CPU time.
The Measurement Request Form has been redesigned to improve the user experience. The form is now logically grouped into three sections: Target, Sampling, and Reporting. A new function to schedule a measurement has been added for Measurement Start.
The Preferences page has been updated to split the section into a non-HCI and HCI required section. This allows users to set preferences for Profile and Insight reports without having to connect to an HCI. The CICS Transactions have been updated for clarity to use Include/Exclude.
Each user will have the ability to control whether these transactions are to be displayed (Preferences). If the switch is off , then the user-specified CICS transactions will not appear in the reports. When the switch is turned on, then these user-specified CICS transactions will be displayed in the reports.
Enhanced and new added functionality collects Strobe and iStrobe usage data, creates SMF records of this data, and provides the records to Enterprise Common Components to upload for use and analysis by zAdviser. zAdviser can then measure the quality, velocity and efficiency of Mainframe development. Refer to the Enterprise Common Components Advanced Configuration Guide Release 17.02 for detailed instructions on how to enable the creation of zAdviser records.
The Strobe hlq .SSTRCLST library start-up CLIST member STROBE has been updated to use the Simple Deploy method. This member allocates Compuware dataset names as specified with the SBNODE(PARMLIB) and the Enterprise Common Components (ECC) CMSC PARMLIB member DDSN nnnn . If you do not specify a DDSNSFX, the ECC hlq. SLCXCNTL library default DDSN00 member will be used. Refer to the Enterprise Common Components Installation and Configuration Guide and the Strobe Installation and Configuration Guide for more information at https://go.compuware.com .
Compuware has enhanced the Compuware PARMLIB parameter processing, including centralized parameter validation. Additionally, some parameters for the Compuware products were changed to reduce their complexity and make them easier to understand and configure. With this cumulative maintenance these changes have been incorporated into the sample parameter members that are supplied in the target sample library.
Enterprise Common Components (ECC) PTF CXS373A provides a parameter migration utility to assist with updating any existing Compuware parameter members at your site. Refer to the Release 17.02 Enterprise Common Components Installation and Configuration Guide for more information about using this utility.
This Rolling 4 Hour Average report allows the user to dynamically change the date range using the time axis. This redraws the graph to represent that time. When the graph plots show the hourly level, the user can click the plot and navigate to the MSU over time for all the displayed LPARs.
Date filtering can use an inclusive range. Numeric fields (such as CPU, EXCP) also contain an inclusive range. The filters can also be used by specifying only one of the boundaries in the range. This will, in effect, be a greater than (>) sign when using lower boundary, or a less than (<) sign when using the upper boundary. Positional wildcarding (?) can be used for alphanumeric fields to limit the values displayed in the filter selection.
Positional wildcarding is now available to Global Monitoring criteria (requires additional Strobe 18.02 ptf). It can be used for both the Include and Exclude criteria, allowing users to incorporate their naming conventions into Global Monitoring criteria.
The Strobe Installation and Configuration Guide has been rewritten and simplified for Release 18.02 to focus on the actual tasks required to install, configure, and customize a Strobe new installation or perform an upgrade on an existing installation. A second, newly created manual, the Strobe Advanced Configuration Guide, includes more specialized configuration and customization information previously contained in the original installation guide. These new guides are available on the FrontLine Strobe documentation site at https://go.compuware.com.
Compuware has enhanced the Common PARMLIB processing controlled by the Compuware Mainframe Services Controller (CMSC), including centralized parameter validation. These changes have been incorporated into the sample parameter members STRBALL, STRB00, and STRT00 in the Strobe hlq .SSTRPARM library. To effect these changes, Enterprise Common Components 17.02 is required with current maintenance applied.
When a Profile containing Notes is exported, it creates both a profile.xml and a notes.xml file. Then, when importing a Profile with the Notes, you will use the ZIP file created that contains both the profile.xml and notes.xml files.
Additional myStrobe filters are introduced to facilitate quicker results. Owner ID and LPAR are now specific for those two columns. This allows a user to quickly narrow the result to a specific user (Owner ID) to find their profile reports.
There is now a preference that can be used to eliminate the IBM CICS Supplied Transactions from the reports. When set to "Off", the IBM CICS Supplied Transactions will not display in the profile reports or the insight reports. This allows the user to focus on the application transactions in the reports.
With Release 18.02, to simplify the installation process for new Strobe installations, the STRB00 and STRT00 members have been modified to only include parameters that should be evaluated at installation time. A new member STRBALL has been provided as a reference point for all other Strobe parameters. Refer to the Strobe installation guide for the complete list of Strobe Release 18.02 parameters with their descriptions, options, and defaults.
Strobe Global Monitoring has been enhanced to provide additional statistics for improved diagnostics. New Global Monitoring parameters using the MVS MODIFY command have been added for generating CICS, IMS, and Global Monitoring Data Pump statistics. Global Monitoring SMF data control parameters have also been added for use with the MVS MODIFY command. Refer to the Strobe installation guide for more information.
Security, Users, Roles, and Groups have been removed from iStrobe and consolidated under Compuware Enterprise Services. They are located under the Compuware Enterprise Services Administration Security feature.
The Measurement Request and Profile reports are separated as they depict different entities. Datatable column headings are relevant to each grouping with each table having independent sorting. Today, users use Strobe ISPF for the status listings. This redesign allows customer’s to move their users out of Strobe's ISPF version and into iStrobe.
The Baseline feature allows users to create average times in the Totals columns for those profiles included in the baseline. The resulting baseline can then be used within myStrobe to compare the totals.
Strobe Release 18.02 introduces Embedded Source Support (ESS), available with Compuware Shared Services (CSS). CSS is SMP/E installed with Enterprise Common Components (ECC) and requires Release 17.02 for Embedded Source Support. The CSS COBOL Language Processor (LP) new ESS command for COBOL Version 5.1 and more current stores the COBOL compiler listing and other program data, not in a VSAM or sequential DDIO file, but instead in ESS records in the executable binary, the actual load module.
Compuware source solutions have been changed to first look for the ESS records and if found will not search for any DDIO file. However, if the ESS records are not found, the usual DDIO file search mechanism, as currently implemented in Strobe, will be used.
Refer to the Compuware Shared Services User/Reference Guide, Release 17.02 version, for more information about Embedded Source Support. Download this guide from the ECC products documentation site at https://go.compuware.com.
Programs are running on zIIPs via SRBs and other technological advances have necessitated changes in how Strobe works. The DIE (disabled interrupt exit) is utilized to obtain more accurate information, which includes SRB and enclave data. New reports in Strobe have been created to show SRB activity within the measured address space. These reports are available only within the Strobe wide profile report.
iStrobe has added a new Insight report named CICS Transaction Utilization. This report allows the performance analyst to specify a date range and a benchmark period of time. The report will then display the deltas for that date comparison for Service Units/Transaction, Transaction Count, and Total Service Units. This additional information is useful for the analyst to identify the overall affect over a period of time.
