Suite Reasons for zTREX Capabilities of zTREX zTREX Viewer Details

Suite Problem:  z/TPF 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! How much resource usage lies below the surface of this z/TPF application? CPU cycles Pool gets and releases Files and Finds Tape resources Etc?

Suite 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 Program level  All resources used at the program level –Counts of MACRO/SVC used

Suite 1.CPU Usage  When dispatching ECBs, zTREX records the time  When the program comes back for service, zTREX records the time again  The delta is CPU usage for that program/function } zTREX ECB SVC Program/ Function

Suite 2.I/O usage, tape records, pool records 3.Compare data from different transactions 4.Program usage  What programs the application calls 2.I/O usage, tape records, pool records 3.Compare data from different transactions 4.Program usage  What programs the application calls

Suite Just collecting data is not enough Programmers must have a way to review and analyze it zTREX provides many visualization and analysis tools  Pie, Bar & Column charts; Tables; Lists

Suite Control activation of zTREX data collection in zTPFGI  Summary data only  Program data only  Summary & Program data  Whether or not to include Instruction Counts After activating zTREX, run a transaction Results can be viewed in zTREX Control activation of zTREX data collection in zTPFGI  Summary data only  Program data only  Summary & Program data  Whether or not to include Instruction Counts After activating zTREX, run a transaction Results can be viewed in zTREX

Suite Each transaction is contained within one file Add transactions to the analysis area to analyze their contents Manage transaction files (Rename, Delete) in the File Groups window or via Windows Explorer Each transaction is contained within one file Add transactions to the analysis area to analyze their contents Manage transaction files (Rename, Delete) in the File Groups window or via Windows Explorer

Suite Expand a transaction to see the ECBs used by the transaction Expand an ECB to show the programs used by the ECB Multi-select to compare transactions, ECBs or Programs ECBs being compared can be in different transactions Programs being compared can be in different ECBs & transactions Expand a transaction to see the ECBs used by the transaction Expand an ECB to show the programs used by the ECB Multi-select to compare transactions, ECBs or Programs ECBs being compared can be in different transactions Programs being compared can be in different ECBs & transactions
