Agenda
Flowchart Performance Tuning Approaches
Unica Campaign and Databases
Campaign Configuration Parameters
Leveraging in-database processing
Custom Macros
2
Target Audience
Organization Roles
– Database marketer/flowchart developer
– Application owner
– Technical application lead
– Application administrator
Responsibilities
– Application Configuration
– Advanced flowchart design and performance tuning
– Creating reusable application objects (catalogs, custom macros, etc)
– Support and training new users
3
in General
Optimize workload distribution between Campaign and the Database
– Table joins
– Merge process vs. database Union, Join, Minus operation
– Data sorts
Optimize Calculation Timing
– Calculate later on smaller audiences
– Calculate earlier as summary table or strategic segments
Partition or simplify the problem
– Break complex logic into simpler components
– Process one chunk at a time or in parallel
Reduce the number of processing steps
– Combine multiple queries accessing the same data into one
– Replace multiple levels of segmentation with derived fields
5
Tuning Approaches, Cont’d
Optimize the use of available resources and tools
– Memory, CPU, I/O
– Virtual memory
– Connections and query threads
– Using DB bulk loaders
– Using DB statistics collection commands
Identify techniques that work well in your environment and package them for reuse
– Product configurations
– Flowchart templates
– Custom macros
Identify techniques that do not perform and develop alternatives
– Frequent audience switches could be avoided with base-dimension table
mappings

IBM Unica Campaign and Databases
Terminology
In Data Marts
“Dimension” tables contain normalized lists of values (States, Zips, Products, etc)
“Fact” tables contain quantitative characteristics of business transactions with foreign
key for dimensions
A table is either a fact or a dimension
8
Terminology Cont’d
In IBM Unica Campaign
“Audience” represents a marketable entity, is associated with one or more key columns
“Base” tables contain audience keys
“Dimension” tables could be joined to base tables or other dimensions
A table could be mapped in multiple times in different roles
9
Best Practices
Have a decision support schema.
– Easy to understand and navigate for the user
– Fewer table joins for performance
Propagate audience keys as widely as possible across the schema.
Calendar based summary tables are not as useful for marketing as they are for
other applications.
The Role of Table Mapping
To provide Unica Campaign with metadata about audience levels and table
relationships
To control the structure of SQL generated by Unica Campaign:
– Joins between base and dimension tables are executed in the database
– Joins between base tables are performed on Unica Campaign server *)
– By selecting appropriate table mapping the users can change the structure of
SQL
Mapping tables at the right audience level(s) could simplify flowchart logic
*) In UC 7.5.3+ this behavior is configurable

IBM Unica Campaign Configuration
Parameters
Setting Configuration Parameters
In Campaign 7.x and AM 7.0.x
– Edit affinium_config.xml
In Campaign 7.x and AM 7.1+
– Edit parameter settings in AM configuration tab
– If a parameter not exposed in AM GUI
• Export current AM settings to XML file by using configTool
• Add parameters to XML file
• Re-import XML file into AM by using configTool again
In Campaign 7.5+ and UC 8+ the installer adds new parameters to
configuration automatically
19
Server Level Configuration
maxVirtualMemory
– Default, can be modified for each flowchart
– Maximum recommended settings
• 1024 for 32-bit versions
• 2048 for 64-bit versions
useInDbOptimization
– Default, can be modified for each flowchart
– Recommended for environments with
• High data volumes
• Powerful databases
20
Database Loaders
Database loaders improve the performance of moving data from the
campaign server back to the Database.
Loaders are a shared resource and other applications can take priority
– Managing parallelism can be a non – trivial exercise
Campaign invokes the loader through OS scripting and sets up data and
control file for the DB loader to consume.
Teradata uses 2 loader utilities
– FastLoad for entering data into an empty table
– Mload for appending data to a table
Performance increases especially seen in Contact History and Response
Processing writes

Leveraging In Database Processing
Eligibility for In-DB Processing
• With In-DB processing turned on, Campaign evaluates
every process box for “In-DB eligibility”
Features do not qualify
– Cross data source table joins
– Audience switching (*)
– Output de-duping
– Cell size limits (*)
– Data sampling (*)
– Campaign macros (*)
– Persistent derived fields (*)
– MailList, Response, Track
• Features that work well

Select
Segment
Merge
Snapshot
Derived fields with raw SQL
macros
Design Recommendations
Scenario
Recommendation
Audience switching
- Use a combination of Select and Snapshot to create a work
table
- Map the work table at a desired audience
Cell size limits
- Create a raw SQL custom macro using database function
rownum()
- Use the custom macro in Select or Segment to limit the
number of IDs in the cell
Data sampling
- Create a raw SQL custom macro using database function
random()
- Use the custom macro in Select or Segment to generate a
random sample of IDs in the cell
DFs with Campaign macros
- Create a raw SQL custom macro using equivalent database
function
- Create a derived field referencing the custom macro
Persistent Derived Fields
Use Extract processes to store calculated data in the database
SQL Macros + In-DB Processing
As of Campaign 7.3+, SQL custom macros work seamlessly with In-DB
optimization
– SQL custom macros in Selects and Segments are now eligible for In-DB
processing
– Both “ID” and “ID + Value” custom macros can be processed in the database
– Logical and arithmetic expressions built out of custom macros can be
processed in the database
– Derived fields using SQL custom macros in Snapshots and MailLists are now
eligible for In-DB processing

Custom Macros – Single Execution
1.
Unica Campaign creates temp table for the results of Order_Aggr(Amount,
sum)
SELECT * INTO UAC_7_8 FROM (
SELECT vOrderDetails.CustomerID, sum(Amount) value
FROM vOrderDetails, UAC_7_0 where
vOrderDetails.CustomerID=UAC_7_0.CustomerID
GROUP BY vOrderDetails.CustomerID ) a
2.
Unica Campaign evaluates selection criteria and creates output cell
SELECT * INTO UAC_7_a FROM (
SELECT DISTINCT UAC_7_8.CustomerID
FROM UAC_7_8 INNER JOIN
UAC_7_0 ON (UAC_7_8.CustomerID=UAC_7_0.CustomerID)
WHERE (UAC_7_8.value > 10000) ) a
Custom Macros – Expression Execution
1.
UC creates temp table for each custom macro
SELECT * INTO UAC_7_e FROM (SELECT vOrderDetails.CustomerID, sum(Amount) value
vOrderDetails.CustomerID=UAC_7_0.CustomerID group by
vOrderDetails.CustomerID ) a
SELECT * INTO UAC_7_d FROM (
2.
SELECT vOrderDetails.CustomerID, sum(Discount) value
OrderDetails.CustomerID=UAC_7_0.CustomerID
GROUP BY vOrderDetails.CustomerID ) a
UC evaluates expression and creates output cell
SELECT * INTO UAC_7_f FROM (
SELECT DISTINCT CustomerID FROM (
UAC_7_d FULL OUTER JOIN UAC_7_e ON UAC_7_d.CustomerID=UAC_7_e.CustomerID)
INNER JOIN UAC_7_0 ON
(UAC_7_d.CustomerID=UAC_7_0.CustomerID) OR (UAC_7_e.CustomerID=UAC_7_0.CustomerID)
WHERE ((UAC_7_d.value / UAC_7_e.value) > 0.1) ) a
