4. Debugger Enhancements

5. DF Insight
Feature in zTPFGI that allows users to view and change DB LRECS in Core Copy while stepping through a debugging session
Access SW00SR, DF data while tracing at source code or macro/instruction levels

6. DF Insight Check real-time changes to DF data, SW00SR as you trace
View/Edit user work area (DBSPA) used to build the LREC
Edit LRECs while debugging
Edit using characters or hex, simply by typing over the existing values

7. Asynchronous Trace

8. The Problem: Tracing ECBs that Originate from “Outside”
“Normal” situation in zTPFGI
User opens terminal emulator
User sets trace options
User enters input into terminal
ECB is captured and displayed
User steps through trace
But what about tracing ECBs created due to external messages coming into the z/TPF system?
Web Services, TCP/IP, Host-To- Host, MQ Series, EDIFACT, XML
Time-initiated ECBs

9. The Solution: ASYNC
Using zTPFGI, user registers for specific ASYNC functionality with certain criteria
zTPFGI monitors incoming message traffic
zTPFGI intercepts incoming messages that meet the specified criteria
Once an incoming message is intercepted, control is transferred to the registered user
Users can then step through and debug, just as they can with any other ECB

10. Asynchronous Trace Implementation
The Administrator…
Knows the kinds of situations developers need to intercept and trace
Defines rules for intercepting those situations
Defines which program to monitor
Data to compare can be present in
Data Level
DECB
Heap
ECB
E.g. Rule=L7 74C(4) 015 = C’$AIRLINE’ AND
= R9 3AB = X’$LNIATA’
Names those rules & puts them in CONFIG file
zVM
CONFIG
File
Rules for Situation 1
Rules for Situation 2
Etc

11. Asynchronous Trace Implementation
The Developer…
Selects a set of rules from a menu and supplies parameter values
(E.G. “LNIATA”)
Is rewarded with an Asynchronous Trace Trace Resource window that looks like a normal “terminal”
Waits for the Asynchronous Trace Resource rules to intercept an ECB from “outside”
Sets trace options
Traces as normal

12. Asynchronous Trace Benefits
Easy to customize via configuration files
Flexible rules: Criteria can capture messages by program, terminal address and combinations of ECB fields
Easy for developers: ADMINS set up the rules; developers just select from a menu and provide parameters (e.g. the LNIATA value)
Programs need not change: Developer need not change E-Type programs to trace external messages

13. New updates in Asynchronous Trace
Support ASYNC trace intercept at C/C++ program entry point
Intercept conditions checked at the CSO entry point
Specify IP address for intercept condition
The IP address compared against the socket descriptor attached with ECB
Specify memory range for condition
Helps to identify a string in the given block of data (e.g.: search for a name in input XML data)
Specify a DECB in condition:
Configuration can be setup to compare data in DECB, just like a data level
User Interface Improvements
Expanded menu that can be filtered

14. Intercept Point (defined in Config. Files)
Summary
Asynchronous Trace intercepts ECBs from external resources when
A specified program is entered
Additional specified conditions are met
Conditions can narrow for a specific test case
A selectively loaded program for the session will be entered by the intercepted ECB
The user...
Controls the intercepted ECB
Controls child ECBs of the intercepted ECB
Can apply trace options
Can trace at the source level if the program is locked for source view trace

15. Installation Process Changes

16. CP User Exit Changes zTPFGI zTPFGI Host Host Software Software

Host
Software
Some zTPFGI host software is CCUEXT related
The Problem
Most companies implement User Exit changes only a few times a year
Implementing User Exit changes can take 6 months to 1 year
zTPFGI can have multiple changes to zTPFGI host software between CCUEXT roll- outs
Needed a design to get these changes loaded faster

The Solution
Use Stub to invoke SO with TPF Software User exit code
Reduces the amount of our mods in the CCUEXT
Faster implementation of changes
Easy and less disruptive

18. IDE Enhancements

19. File Compare Compare a file to: Drag & Drop files to compare
Previous versions derived from automated backups
Itself as it was initially opened
Any open file
Any other text file from any available library or repository
Drag & Drop files to compare
Or browse to select files to compare

20. File Compare Opens in the zTPFGI Editor area Easily identify:
Added lines
Deleted lines
Changed lines
Easily navigate through differences
Easily integrate changes from these sources into the current file

21. Visual Log
Capture a variety of trace and audit trail information that can be viewed in any modern web-browser, including
Terminal Inputs / Outputs (Added Japanese language support)
ECB Activity
Screenshots of a variety of available zTPFGI windows, including editors, terminals, trace resources and ECB windows

22. Visual Log View the log in any modern web-browser, e.g.
Terminal Input
ECB Activity
Terminal Output
Screenshot
Distribute the log as a zip file

23. zTTFS Enhancement

24. High Level Overview
