Asynchronous Trace
zRTF (Regression Test Facility)

3. Cadillac Load: Improving the Load Process for Users
zLinux
Loading encompasses several tasks:
Compiling-building source
into SO files on z/Linux
Transferring SOs
from z/Linux to a zTPF system
Loading SOs for use
on the zTPF system
“Locking” Source for trace
in the debugger
The user must manually…
Select correct zTPF system name
before loading
Wait to lock in source
until after programs loaded to zTPF
CPP C
ASM 01 10 01 10
zVM
zTPF / VPARS

4. Cadillac Load When user clicks Load, Cadillac Load will…
Offer the correct system
If connected to a system
Make locking source quick. User can choose:
Lock in all source files
Select source files to lock
Refresh currently locked source files
Fewer user steps saves time

5. File Compare 1 Users need compare 2 venues for compare supported:
To see what changed during editing
To roll back or resolve conflicts in source files
2 venues for compare supported:
Built-in compare
External compare tools
WinMerge
BeyondCompare
Other choice (configurable)
Compare features:
See differences between files
Move differences between files
What files?
Any two files—host or PC
File with itself as originally opened
File with any automatic backup
File with its library version 2

6. zLinux Terminal Users wanted zLinux access directly in zTPFGI
Enter simple zLinux commands
Receive output
Reset zLinux passwords
Run input scripts via Message Run facility

7. ECB List View zTPFGI shows graphical ECBs on tabs
Some users wanted to see all ECBs for all terminals at same time
New ECB List view
Shows terminals & ECBs
Double-click to edit ECB
Exit an ECB
Exit All ECBs

8. Scripting Through VM
Select best fare
Automate execution of multiple test scenarios with multiple steps
Example Scenario:
Passenger wants to book flight from Washington to Chicago based on best fare
If flight with best fare is fully booked, find flight with available seats
If flight with available seats is not found, execute next command based on result of previous command
etc.
Other Scenarios:
Trigger Availability entry from various “point of sales” to measure path length
Verify 8000 PNRS after schedule change if SSRS are intact
Verify if recoup isuccessful. Script for online chain-chase
Available Seats
Book Flight (create PNR)
No Seats
Find flights with available seats
Flight found with available seats
No flights found with available seats
Book Flight (create PNR)
Execute next conditional command

9. Scripting Through VM Customers already had VM scripts
Wanted to re-use them
Need to repeat common zTPF commands using VM EXECs
ZGI Command terminal
Provides interface for talking to VM directly & via EXECs
Accepts 2 command types:
ZGICMS: Calls VM EXECs
ZGICMD: Calls special zTPF commands
Message Run Input Files
Now support ZGICMD/ZGICMS
Other uses:
Test “robots”
Set user profiles
Run preload simulations
Do performance measurements

10. Other Debugger Updates
Added terminal support for
ALC Printer
CFIN (Consumer Finance terminal)
LOC 3270 terminals
Overlay Panels (DSECT) gallery
Machine Trace View
Write tape output to VM file
Preference available to log the data to a VM file
The preference can be set using the ZGI command
Trace macro POST option
Stop before/after macro execution
Reset zLinux passwords option
zAutomation*
zTPFGI’s facility to efficiently bring up VPARS remotely
zTREX*
Transaction Recording & Examination
Immediately identify which applications are using which resources
Audit and Usage logging*
Purpose of audit logging is for the administrator of zTPFGI to monitor modification in the system
Usage logging provides the usage statistics for the product and for the users
* Find out more in the Applications Development Subcommittee Meeting

11. ASYNCHRONOUS TRACE

12. 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 that originate from outside?
TCP/IP, Host-To-Host, MQ Series
Messages from a non-simulated terminal
ECBs triggered automatically in the system (Time initiated)

13. Solution: Asynchronous Trace
External Resource
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
Intercept Point (defined in Config. Files)
zVM
zTPF / VPARS
Config.
Files
Asynchronous Trace. Trace
Resource

14. Asynchronous Trace Implementation
zVM
CONFIG
File
Rules for Situation 1
Rules for Situation 2
Etc
The Administrator…
Knows the kinds of situations developers need to intercept and trace
Defines rules for intercepting those situations
Names those rules & puts them in CONFIG file
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 Trace Resource rules to intercept an ECB from “outside”
Sets trace options
Traces as normal

15. 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)
Configurable display: ADMINS can setup what data will be displayed in the Asynchronous Trace Trace Resource window when the ECB is intercepted

16. zRTF Illustration zTPF zTPF PROGRAMS DATA Input Script Output Log 1 2
Messages
zTPF PROGRAMS
DATA
Output Log 1
Events
Planned changes are made to system
Input script is run again, producing new output log
Baseline and second-run data are compared
Show title & zTPF only
At a basic level, zRTF measures the impact of proposed changes by comparing changes with a base-run.
Show input & output 1
First, zRTF runs the test script and logs the output.
Show changes to system
Next, the planned changes are made to the test system,
Show phase 2
and the test is run again. (If one has two identical test systems, one can also run these two phases in parallel if required.)
Show compare
Then, the pre-change run can be compared with the post-change run to measure the impact on the system. 2 2 1 =?

17. zRTF Updates Now integrated with zAUTOMATION
Can use VPARS from pool during run and release back to pool once test complete
Now integrated with ZGICMS and ZGICMD
ZGICMS
Invoke REXX EXEC from test unit
EXEC can issue zTPF input, interpret zTPF output, make decisions etc.
ZGICMD
Set user preferences, execute zTPF inputs, reallocate terminals etc.
zRTF compare utility enhanced
More options and functionalities
Test unit supports different input formats for PH1 and PH2
Enables testing of application entries for which input format has changed
Test unit supports list of programs to load for PHASE II run
OLDR file
PC Interface enhanced
Right click an input file or RTFMSG file to initiate zRTF run
