19. Implicitlyregisters start and end time of each report that runs from the UIConsole.
Then it will register the report in da.SYS_PROGRAM_AUDITevery time the report query
is run.
Explicit registrationin SYS_DEBUG_LOG using Report packages
use the following pl/sql Before_Report
da.dbk_sys_audit.Jasper_Report_Begin_Query('APCVD');
T_Step := DBK_JSR_REPORTS.Set_Step_Debug(G_Package_Name, T_Procedure_Name,
'A: Context Variables');
Then it will register the debugmessages in da.Sys_Debug_Log
CMiC developed it's own Auditutilities, two of which are used in
Reports (Securityissues):
FROM THE DESK OF JIM ORIOTIS

27. HOW DO
WE ADD
VALUE TO
OUR
REPORTS?
Consolidate Multiple Reports into One Report
Add Other Datasources: External Databases, APIs, Files
Include Related Documents
All the InformationIn One Place
Consolidate totalsby passing values from Subreports
to the Main Reports
Highlight critical data with conditional formatting
Assist in Analyzing the Data
Make it easy! EliminateUnnecessary Params & Fields
Make it fast! Know your execution plan & SQL tune it
Don't Waste Their Time

28. FINDING THE
BOTTLENECKS
IN YOUR CODE
Performance problems can occur when
consolidating reports and adding data from more
places.
Resolving the problem starts with understanding
the execution plan.

29. READING EXECUTION PLANS IT'S NOT ROCKET SCIENCE IF YOU BREAK IT DOWN
Go to theFirst
Unvisited Leaf
Start at the Depth
Go to the Parent
of the First Leaf
Followthe
IndentationsOutward
Go to theNext
Unvisited Leaf

30. WHAT DO WE WANT FROM OUR EXECUTION PLAN?
Accurate
Row
Estimates
Efficient
Access Paths
Minimal I/O
Quick
Operation

Better
Performance
Execution Plan
Shows optimizer decisions
Shows Key Performance Indicators for the SQL
Has a hierarchal tree format

34. END-TO-END APPLICATION TRACING CAN GIVE YOU DIRECTION
How Do I
Know If It's My
SQL???

35. END-TO-END
APPLICATION
TRACING CAN
HELP
Helps diagnose performance issues
Allows viewing application
workloads in different ways: by
session, client, service, module,
action, and application.

36. APPLICATION TRACING IN THE WILD: TKPROF
Row Source
Plan
Rows Actual number of rows returned ateach step
Row so urce operation executed
Count Number of times procedure was executed
CPU CPU time in seconds
Elapsed All figures arecumulativeat each step
I/O Statistics
CR number of consistentreads
R physical reads (slow)
W number of writes
Parse, Execute
& Fetch
Statistics
Execute (query): Number of blocks visited to find the rows for the
operation
Execute (current): Number of buffers accessed to perform the update
Execute (rows): Number of rows actually accessed or processed.
Look for overparsing,readingtoo many blocks to return few blocks
(inefficientaccess path),inefficientlooping.

Sort your TKPROF
Use sorting options to see the highest resource usage queries first
For example: Use option: EXECPU CPU time spent executing

37. APPLICATION TRACING BY SERVICE
Run the trace on the new service
Set the application or client to connect using the new service
Start the new Service
Create the new Service
Service A logical representation of a
database environment to the
outside world
Use a new service with each
new client application

38. OVERRIDING OPTIMIZER DECISIONS
Rewrite the
Query
Try query
transformations
Try SQL Macros
Change Your
Access Path
Add or Remove
Indexes
Gather Table
Statistics
Inaccurate statics
can cause the
optimizer to make
incorrect decisions
Change Your
Join (and Non-
Join) Predicates
Most restrictive
table first
Use the most
efficient join type
Use (or Don't
Use) Hints
Hints can limit the
optimizer's options,
so try to avoid hints

(SQM)
What are SQL Macros?
A way to perform complex logic processinginside SQL statements
Functionsthat can factorout commonSQL expressionsand statements
into reusable,parameterizedconstructsusablein other SQL statements.
Benefits
FasterExecution
Reduces Context SwitchingBetween SQL engine and PL/SQL engine
Transparent tothe optimizer, and compatiblewith query/view merging
Single Pointof Definitionfor Logic
Types of SQM
Scalar (SELECT, WHERE, GROUP BY, HAVING,ORDER BY clauses)

Eclipse IDE,an Open Platform for Professional
Developers.
Eclipse allows you to independently developtoolsthat
seamlessly integratewithothertools.
Very flexibleand extensible platform.
Theseguidelines are intendedfor use by designersand
implementorsof an Eclipse userinterfaceextension.

44. ECLIPSE INTERFACE PLUG-INS FOR MORE CODING FUN
Jaspersoft Studio uses the Eclipse
environment to organize all the
resources. This means users create
projects that contain images, styles,
libraries, and other files needed for
report development. This is done in the
Project Explorer view .
