1980s application:
in-house users only; simple data, single data store
Today:
users are customers; data is complex, heterogeneous, often distributed
Transaction Manager:

Users:
company
employees
Database:
IMS DB or DB2
Users:
employees,
customers (public),

Where did the delay occur?
 A single transaction can
have activity across
many subsystems
 To quickly identify
performance issues,
you need to track the
entire transaction
 Subsystem-specific
approaches and tools
offer a limited
perspective
 Each subsystem has its
own activity log and
SMF records
3
IMS

Traditional approaches and tools based on
“silo” model

There are many tools to help analyze individual transaction
environments on System z:

not four!

Each tool is well-suited
to its environment, but
SME uses their own
tools

IBM Transaction Analysis Workbench for z/OS
 A tool for problems in the big picture:
– For “first responders” and subject-matter experts (SMEs)
– For SMEs in different areas
 Provides a life cycle view of transaction activity across
subsystems
– Changes the way problem resolution is performed
– Ensures everyone is looking at the same transactional data
 Goes in-depth.
– Uses SMF, trace, and log records to follow transaction flow
 Better assignment of problems to the correct group
– Improved confidence in problems assigned to experts

Cross support is key with fewer staff
 Why is support so difficult?
– SME may be in silos
• Cross training may be difficult
• Takes too much time using current tools
• Unable or unwilling to cooperate easily
 What does good cross-platform tool achieve?
– Conservation of SMEs’ time (a valuable, limited resource)
– Transparency of information (everyone using the correct data
from the same time period)
 SMEs need to see the big picture and the benefit of
collaboration
– Reduced time to resolution
– More SME time focused on problem resolution
– Cross-training of first responders and SMEs7

What’s new in Workbench V1.2
 CICS-DB2 and IMS-DB2 transaction exception processing
Was the problem in CICS or DB2? IMS or DB2? (CICS-DBCTL already
supported in V1.1.)
 Enhanced support for DB2 trace records
Detailed field-by-field formatting for more than 60 IFCIDs.
 Workflows and session templates
Subject-matter experts (SMEs) can define a workflow (a sequence of
analysis tasks) and save it in a session template. When creating a
new session, users can select the session template that best
matches the report problem.
 Eclipse-based rich client platform (RCP) user interface
Implements a subset of the ISPF dialog: create a session; run a
workflow; assign to appropriate SME.
 Automated SMF file selection
 SMF 42.6 DASD Data Set I/O report
8

Problem: today’s instrumentation data overwhelms
traditional tools
 Good performance monitoring should identify possible performance
issues before they become critical
 Today's systems create so much instrumentation data that existing
techniques cannot keep up: takes too long, costs too much!
9
Instrumentation data
Report
Traditional batch
analysis/reporting tool
• Processes and reports on all
records
• Processing time and cost
grows with size of
instrumentation data,
beyond practical limits
• Reports can grow too long to
be useful, and contain
unwanted detail

Solution: Exception detection
10
Terabytes of instrumentation data
Workbench
Transaction
index
Exception: a transaction that matches specific exception
criteria, such as long response time or an abend
z/OS batch
process that
efficiently crawls
data for
exceptions
Reporting
and

Index
Workbench exception processing
1. Transaction indexes are created by the workbench (a session workflow will create them)
2. They are used to identify all the transaction and UOR workloads in IMS, DB2 and CICS
3. The transaction index is a special extract - one record per transaction in time sequence
4. Contain summarized performance and resource usage information
5. Can be filtered to include exception transactions only
6. Can be used for reporting and to identify problem transactions

DB2 exception extract and reporting (DB2X)
 The DB2 exception extract and reporting facility helps to identify
and analyze problems associated with DB2.
 DB2 accounting records (SMF 101) are checked against user-
specified exception criteria. DB2 threads that are identified as
exceptions are reported and extracted for further analysis.
 The detailed list report lists those DB2 accounting records that
triggered an exception – with the reason
 The extract writes those DB2 accounting records that triggered an
exception to an extract data set. This data set can then be used for
more specialized analysis, for example:
o Tivoli OMEGAMON XE for DB2 Performance Expert
o Transaction Analysis Workbench ISPF dialog interactive
analysis; merged with the DB2 log and other traces to
examine the transaction lifecycle picture.

For each exception that was triggered, the thread and exception details are listed
SSID DB2 subsystem id
Correlation Correlation id
Connect Connection name. If the name is not available then the connecting system type is substituted
Plan Plan name
Auth id Authorization id
Time End of accounting interval stamp. This is not the thread start time.
This time matches the record timestamp displayed in the ISPF dialog.
Exception The exception event that was triggered – its description and value
Threshold The exception threshold that was exceeded
LUWID Logical unit of work id, used to uniquely identify the DB2 accounting record.

Interactive Log analysis using the ISPF dialog
 Allows you to view transactions events across all the
subsystems
 Merges data sources from IMS, DB2, CICS and MVS
 Displays records with friendly descriptions and useful
information
 Analyze transaction event latencies with relative and
elapsed times
 Use a filter to show required records only
 Use tracking to isolate all the records associated with
an individual transaction
 Select a record to see more detail (full mapping)15

Enhanced support for DB2 trace records (cont.)
 Generating DB2 trace records can be expensive, and can
result in very large log files: you do not want to simply start all
traces.
 Workbench introduces the concept of trace “levels” (1 - 4) that
categorize IFCIDs based on their usefulness (for transaction
analysis) and cost overhead:
– Program invocation
– SQL
– I/O
– All (caution: may result in high volumes of data)
 In the ISPF dialog, enter the command:
TRACE n
(n: 1 - 4) to show progressively more detail. TRACE 4 shows all
available trace records.20

Workbench ISPF dialog
1. Sessions: collaborative approach to problem determination
2. Controls: common place for shared definitions
3. Systems: define IMS, DB2, CICS and MVS systems – allows

How Workbench can help
application development
teams
31

Application releases must work and perform when
deployed
 Application teams perform validation testing during roll-out
– Is performance a part of validation testing?
– If performance validation is done, who does the validation?
– What criteria are used?
 Does the evaluation occur at the transaction level?
 What is the cost of performance validation testing?
 What is the cost of a failed roll-out due to poor
performance?
 Does system programming have time to help?
32

Inhibitors to instrumentation data usage by application
development teams
 Value of instrumentation data not known
– May not know what is available and how to use it
– Not a traditional development tool
 Do not know how to obtain the data or data access
not allowed
– May not have access to system parts
 Limited or no knowledge of tools that use
instrumentation data
 Limited access to system programmers’ time
– Reluctant to bother system programmers to get help
33

Solution - Value of instrumentation data to application
development teams
 Workbench demystifies instrumentation data:
– Allows application teams to evaluate
• Transaction response times
• Application database update patterns
– Allows application teams to diagnose application errors
and/or performance issues
– If SME help is needed, they can ask better questions of
the right SME
34

How Workbench helps
 Automates the collection of instrumentation data
– Application development teams do not have to acquire those skills
 Performs automated reporting of validation testing
– Includes reporting via CICS PA and/or IMS PA, in addition to its
own reports
 Analyses instrumentation data for performance exceptions
– Provides easy recognition of validation testing against expected
results
 Provides transaction life cycle views of transaction exceptions
– Identify what part of transaction is causing problem
 Saves results of each validation testing run
 Facilitates collaboration with system programmers and/or DBAs
for help with transaction exception diagnosis35

Summary of application team benefits
 Automate tasks often unfamiliar to application teams
– Data acquisition – get the data needed for problem analysis
– Autonomics – automated transaction analysis (life cycle)
– Reporting – basic reporting without tool-specific knowledge
 Enables collaboration with other experts
– Shared data approach
• DBA, system programmer provide assistance when needed
– Fewer SMEs may need to be involved
 Analysis of applications performance testing
– Exceptions process provides evaluation of validation runs
– Deeper transaction evaluation if exceptions reported
36

Scenario: IMS DB2 problem
1. On the following slides, we present an example
scenario: a user has reported a long transaction
response time for an IMS transaction performing DB2
updates
 The analysis is divided into two parts:
1. The first responder:
• Registers the problem in the Workbench session manager and
collects the log files
• Follows a process orientated script to assign problem to initial
expert
– Based on what is found
2. The subject-matter expert performs a “deep dive” on the
problem: reviewing the reports, and using interactive analysis
to identify the specific log records for the cause of the
problem

Transaction life cycle investigation 1. Start tracking a
transaction
(here, a CICS
transaction)
2. See the
transaction life
cycle events
from the related
logs (here, an
SMF file and a
DB2 log),
merged
together with no
preparation
required
3. Notice the jump
in elapsed time
4. In this case, the
problem was
caused by a
table scan in a
DB2 stored
procedure.
A drill down of
the DB2 trace
was able to
determine this.

A DB2 expert can
now use the DB2
Log Analysis Tool
to investigate the
associated DB2
table updates,
based on the
transaction’s URID

Problem resolution: end of scenario
 The cause of the IMS transaction problem has been
narrowed down to a slowdown in DB2
 Sufficient information about the DB2 update activity has
been collected and can be passed on to the DB2 DBA for
further investigation
 Automatically locates log files for the problem time
range for supported subsystems
– SMF
– IMS log
– DB2 log and trace
 Enables a collaborative problem analysis:
– Between first responders and subject-matter experts
– Between experts in different areas47

SMF 70-1: RMF Processor activity
CPU constraints are
one of the most
common causes of a
slowdown in
performance, and often
has flow-on effects
including contention.
Out Ready identifies the number of address
spaces waiting for dispatching on the CPU
CPU Busy and IO Rate
are the classical system
performance indicators.
Look for spikes that might
indicate a slowdown.

With the advent of large amounts of cheaper memory,
Page data set performance is often less of a problem
today, but none the less should be monitored
occasionally for constraints.

IMS and CICS still use large amounts of CSA and ECSA for
common storage. In the event that storage cannot be obtained,
subsystems can stop or worse.

IMS database locks that are held
by transactions for an extended
period (several seconds) are
logged to SMF; and can be
analyzed to determine if there is
an application problem.

CICS and IMS both rely
on log streams for
critical services;
including message
handling and journaling.
Problems can be
avoided by monitoring
their I/O and offload
activity.

From the previous JCL request, it is simple to identify the IMS subsystem
messages associated with the transaction failure.

CICS DBCTL
 For all CICS transaction you can analyze CMF (SMF 110) records.
 However CMF records do not contain all of the details of the IMS
events that are triggered by DL/I requests. Those details are in the
IMS log.
 Transaction Analysis Workbench enables you to analyze CICS
DBCTL transactions using:
– CMF records
– IMS log records
– A combined view of both
 In particular Workbench enables you to analyze exceptions:
CICS DBCTL transactions that abended or had a long response
time.
