Data Warehouse Load Confirmation
• Lab 2.1 Warehouse Load Confirmation – Main Steps• Start Oracle Business Intelligence Enterprise Edition (OBIEE) �
– ./oc4j –start
– ./run-sa.sh start
– ./run-saw.sh start
• Review data using Interactive Dashboards and Answers
• Duration: 1.0 hour
For more information on Oracle BI Enterprise Edition,refer to the documentation located on the DVD
in the BIEE_10_1_3_3_3_Docs folder
Informatica Tools Overview (Viewlet)�
• Lab 2.2 Informatica Tools Overview – Main Steps
• Review features of the Informatica tool
– Informatica Repository Manager
– Informatica Designer
– Informatica Workflow Manager
• Duration: 1.0 hour
For more information on Informatica,
refer to the Informatica product documentation
Type I CustomizationAdding Additional Columns
• Type I customizations involve extracting additional
columns from source systems that are already mapped
and loading the data to existing data warehouse tables.
• Extend mappings
– Existing mappings and tables are extensible
– Sample placeholders demonstrate how to pass and store
additional data
– DO NOT modify existing logic or columns
Type I CustomizationTypical Extension Steps
1. Copy the appropriate mappings to a custom
Informatica folder
2. Extend the source and target tables by making
changes to the tables in the database
3. Extend the SDE and SIL mappings by bringing in the
additional columns.
4. Copy the appropriate workflows to the custom
Informatica folder.
5. Modify the workflows.
6. Update the DAC with the necessary changes.
Type II CustomizationAdding Additional Tables
• Use pre-packaged adaptors to add new fact or
dimension tables to the data warehouse, regardless of whether they are already mapped.
• Build new SDE and SIL mappings.
• Use required system columns
• Register tables and indices in DAC
• Register new tasks for Informatica workflows, assemble
subject areas and build execution plans in DAC
• Use naming convention WC_TABLENAME_<table type>
Type II CustomizationConsiderations
• Create custom SDE and SIL folders in Informatica and
make changes to them.
• Do not change objects in shipped folders
• Create custom workflows for all customized mappings
– Each workflow should load only one table.
– Workflow name should match a session name that is used inside
the workflow.
– Set the appropriate source and target connection values in
Informatica Designer.
– Register workflows in the DAC.
Customization Labs
Goals of this set of labs:
• Allow you to gain high-level working skills with Informatica PowerCenter tools
• Familiarize you with the steps needed to customize and
extend the OBAW in line with Type I customizations
Considerations to keep in mind
• The Informatica portions will be conducted using a
viewlet so you will perform actions inside the viewlet that
do not reflect real behavior exactly. These deviations will be noted in the lab steps where appropriate.
• The end state mapping has already been completed.
• You cannot make a mistake. Seriously, if you make a
mistake the viewlet will not advance (of course you can
always advance using the forward button at the bottom
of the viewlet).
Use Case
• Executives want to see additional data elements related
to a customer outreach initiative in the reports that are
related to customers.
• The outreach initiative information is maintained in an
Excel spreadsheet by the Director of Customer
Satisfaction.
Use Case: Technical Enablement
• In the Oracle E-Business Suite 11.5.10 OLTP Database
– The table LAB_CUST_OUTREACH_ZONES was created to hold the data on customer satisfaction outreach zones and the assignment of current customers to these zones. This data was imported into the database using Oracle Data Integrator.
• In the Data Warehouse:
– The table LAB_W_CUSTOMER_LOC_D was created as a copy of W_CUSTOMER_LOC_D with a new column called X_OUTREACH_ZONE added after the X_CUSTOM column.
– The table LAB_W_CUSTOMER_LOC_DS was created as a copy of W_CUSTOMER_LOC_DS
• The source table only has five records since the real point of the exercise is to work with the tools and flow versus loading hundreds of rows of data.
Informatica Custom ETL(Viewlet)�
• Lab 2.3 Informatica Custom ETL – Main Steps
• Create a new Repository folder
• Define Source and Target tables
• Create new Mapping
• Create new Workflow
• Duration: 1.0 hour

– Folder
– Tasks
– Subject Area
– Execution Plan
• Duration: 1.5 hours

DAC Configuration for Customization
• Lab 2.5 DAC Execution / Custom ETL Confirmation –
Main Steps
• Run custom Execution Plan
• Verify data using SQL*Plus
• Duration: 1.5 hours
