zTPFGI Facilities Suite www.tpfsoftware.com Focus Three of zTPFGI’s facilities: zAutomation zTREX Logger Suite www.tpfsoftware.com zAutomation Facility to Bring Up VPARS Remotely Suite www.tpfsoftware.com Introduction • Part of zTPFGI suite of products and it is VM based. • Efficient and Effective management of the process of bringing up the VPARS. Resource User • VPARS classification On Demand Shared System Automation Suite www.tpfsoftware.com Overview Client A Client B Client A requests VPARS from pool Worker A starts another worker A which brings VPARS to norm state, then disconnects B V2 VPARS Pool V1 V2 V3 V4 V5 V6 Worker A starts another worker V3 V3 V4 Legend Private Worker Not Logged on NORM State (product is not activated) which gets another VPARS ready for dispatch, then disconnects Client B requests VPARS from pool Worker B starts another worker which finds a VPARS that is ready for dispatch in the pool, so uses it Worker B starts another worker which gets another VPARS ready for dispatch, then disconnects Ready for dispatch Suite www.tpfsoftware.com Role of zAutomation • Assigns worker machines to bring up VPARS, Based on the configured status chosen by the user. • Constantly checks VPARS status in the POOL file and takes relevant actions Bringing up stand by VPARS or ERROR handling. • If the user chooses a Shared VPARS which is not available zAuto will bring up the Shared VPARS – for all users to sign-on. • Based on the configuration option always brings up more stand-by VPARS. When the new USER signs-on, the stand-by VPARS is immediately allocated (thus reducing wait time for the end user – in starting a VPARS) • Puts all the stand by VPARS in “CP TR EXT” mode so that VPARS are not using CPU cycles. Suite www.tpfsoftware.com Role of zAutomation • zTPFGI with zAutomation Multiple VPARS can be grouped as POOL – – With a logical name for the POOL and can be shared by a group of users. When user signs-on using zTPFGI – An available VPARS from the pool is allocated with the clean database. For On Demand – – User is guaranteed a VPARS with clean database all the time, but can be different VPARS, every time he signs-on. • zRTF with zAutomation Two VPARS available from the pool is fetched and allocated for zRTF RUN. – Phase 1 and Phase 2 During zRTF process termination, VPARS are returned to the POOL. With zAutomation and pool VPARS – Suite no need of reserving TWO VPARS for zRTF run all the time. www.tpfsoftware.com On Demand VPARS • One or more VPARS are grouped together as pool a logical resource pool name is assigned. • When user action requires a VPARS, zAuto Client A Client B V1 V2 VPARS Pool V1 V2 V3 V4 Not Logged on In Use Suite Stand By fetches an available VPARS from the pool and assigns it to the user. • The pool VPARS is allocated to the user only when user action demands the VPARS, hence referred as “On Demand” VPARS. • During the termination of the user action VPARS is returned to the pool • Configuration files are used to define the POOL of VPARS. • Using the configuration file, VPARS can be added or deleted. • In case of pool VPARS, only one user can use the VPARS. • Every time a pool VPARS is allocated to a specific user VPARS with a clean database is allocated. www.tpfsoftware.com Shared VPARS Client A Client B • Some VPARS can be configured as Shared VPAR Client C Implying the VPARS is shared by multiple users. • Shared VPARS can also be configured Client D • Resource Manager brings up the shared VPARS V1 Not Logged on / Disconnected In Use Suite to be monitored by Resource Manager to the usable status only if the VPARS are down. • In case of shared VPARS multiple users can log on to the same VPARS at the same time and can use TPF Software products (zTPFGI, zDFX, zRTF). www.tpfsoftware.com Server / User Configuration • Server Information • Pool or On-Demand • VPARS name • Names of other VPARS • If type is POOL Server • User Information • Display summary messages to Console • Display detail messages to Console • Used by Administrator • For Debugging Suite www.tpfsoftware.com Automation Configuration • Resource Configuration OSA information PMR information Tape information Etc. • Command Section Automation Suite Command to execute Action to take – for good rc Action to take – for bad rc www.tpfsoftware.com User Exits • Send error message to Administrator team for the following cases Problem in updating the VPARS POOL file Problem in bringing up the system User Exits • Get the password for the VPARS • Extract the value from the previous command and set it in the next coming commands Suite www.tpfsoftware.com zTREX Transaction Recording and Examination Facility Suite www.tpfsoftware.com Overview • Reasons for zTREX • Capabilities of zTREX • Types of collection in zTREX • zTREX Viewer Details Suite www.tpfsoftware.com Why zTREX? Problem: zTPF Applications that use too many resources degrade system performance But it’s difficult to see the problem Solution: zTREX – Allows programmers to identify which App is using what resources You can see just how big a problem you have! Suite How much resource usage lies below the surface of this zTPF application? • • • • • CPU cycles Pool gets and releases Files and Finds Tape resources Etc? www.tpfsoftware.com Capabilities zTREX Analyzes Performance at Several Levels • Transaction level All the resources used by the transaction Identifies all the ECBs • ECB level All resources used at ECB level Identify programs and functions • Individual program/function level All resources used at the program/function level – Counts of MACRO/SVC used Suite www.tpfsoftware.com Types of Data Collected • Summary of data collection Resource usage is collected by each ECB Data is collated on the transaction level for presentation • Program level data collection This is the detail level of data collection for each program called by ECB The data is collated at the ECB level for presentation • File usage data collection This records information on every file used by an ECB Suite www.tpfsoftware.com Viewer Details 1. CPU Usage zTREX collects CPU usage at ECB level 2. Memory Usage Application-level memory Core blocks, heap space, system work blocks 3. I/O Usage, Pool Records Find and Files GETFC/ RELFC 4. Program Usage What programs/ functions the application calls 5. Macro Counts Overall count as well as individual count for each macro TPFDF macro count Suite www.tpfsoftware.com Logger Logging Facility Suite www.tpfsoftware.com Logger • Test System Management Helps operators to analyze the events happened in a test system Gives information on the changes to the VPARS – – – – – System commands executed System wide program load Private program load Core altered File altered • Tool Management Helps Tools Administrator to analyze the usage of the products • Debug problems in Products Collect debugging information on Global Level Helps us to narrow down to the problem Suite www.tpfsoftware.com Components of Logger Data Worker Log Server • Save Log Data to Log Server Worker Admin VPARS Suite • Collect Log Data from: • VPARS • Worker VPARS • View Log Data in zTPFGI www.tpfsoftware.com Components of Logger • Data Collection Software component is responsible for data collection and sending it to the server to save the data in a common place in VM. • Log Server / Data Repository The collected data are stored in the common Data repository. Log Server is a VM machine always listening for Log data from either the VPARS or the Worker Machine for the log data. The server refers to configuration files to determine the location of each type of log data and The Server also does the house keeping activities for each log type. • Report Generation Utility provided in zTPFGI To generate report on the log data Based on the filters provided by the administrator There are no separate steps to install this component. The utility comes as a part of zTPFGI. Suite www.tpfsoftware.com Demo Suite www.tpfsoftware.com
