1. DAC Introduction

1. Is a centralized console to design, configure and execute ETL for loading

the Oracle Business Analytics Warehouse 2. Single command and control point for the OBAW 3. Provides a framework for managing the entire life cycle of OBAW

implementations 4. Provides an ‘easy-to-use’ interface for deploying, defining, administering

and monitoring of Data warehouse processes 5. Simplifies ETL customization and execution

1. Define ETL subject areas and execution plans 2. Automate configuration of ETL for full and incremental load of subject

areas 3. Automatic index management 4. Prioritize and load balance ETL workflow execution 5. Compile historical tracking of diagnostic ETL logs 6. Provide restart of ETL execution from point of failure 7. Update database statistics on OBAW tables and indexes

6. DAC present version is 10G (10.1.3.4.1)

2. DAC Installation

1. Download software from oracle website

http://www.oracle.com/technetwork/middleware/bi-enterprise-edition/downloads/bi-downloads-1525270.html

Ok-ok-ok


3. DAC Configuration

Step1: Sign in to DAC

Startàall program DAC à client à provide

Connection: DAC

User name: DAC

Password: DAC

Step2: Creating Container

In DAC repository we may have ‘n’ number of containers but always best practice is create only one container.

It is useful to store DAC metadata (task names, subject area, names, execution plans etc…)


Process:

· Go to file menu --> new --> Source system container--> provide id as rritec123 and name as rritec

Click ok --> ok.

· Select create new Container.. --> Click ok.

Step3: Configure Database.

· Click on Design tab -->select rritec container · Click on Setup tab --> double click on Physical data sources --> click on New -->

provide

Name: ORCL

Type: Source

Connection type: Oracle (oci8)

TNS name: ORCL

Table owner: Scott

Table owner password: tiger

Dependency priority: 1

Data source number: 1521

· Click on save --> ok. · Similarly another connection with name as ORCL_DW, owner as B165_TARGET

and owner password as RRitec123

Step4: Configure Informatica Repository Server.

· Click on Setup tab --> double click on Informatica Server --> new -->

Name: INFORMATICA_REP_SERVER

Type: Repository

Hostname: local host

Server port: 6005

Domain: Domain_rritec

Login: Administrator


Password: Administrator

Repository name: BIA_RS (open Informatica Admin console and name as per the console)

· Click on save --> test connection --> ok.

Step5: Configure Informatica Integration services.

· Click on Setup --> Informatica Services -->go to new

Name: INFORMATICA_DW_SERVER

Type: informatica

Services: BIA_IS

Domain: Domain_rritec

Login: Administrator

Password: Administrator

Repository name: BIA_RS (open Informatica Admin console and name as per the console)

· Click on save --> test connection --> ok.

Step6: Configuring informatica physical folder.

· Go to Tools menu --> Seed Data --> Task Physical Folder · Click on New --> name it as CUSTOM_RRITEC --> click on save --> Close.

Step7: Creating Logical Folders.

· Go to tools menu --> Seed data--> Task Logical Folder · Click on New --> Name it as RRITEC --> click save --> close.

Step8: Mapping Logical folder And Physical folder.

· Go to Design tab --> double click on Source System Folders --> select New -->Select

Logical folder as RRITEC

Physical folder as CUSTOM_RRITEC

· Click on Save.


Step9: Creating Logical Data Sources

· Go to Tools menu --> Seed data --> Logical Data Source · Click on New --> name it as ORCL_SCOTT_SOURCE - > Save it. · Again click on New --> name it as ORCL_B165TARGET_DW --> Save & Close.

Step 10: creating Task Phases.

· Go to Tools menu --> Seed Data --> Task Phases. · Click on New --> Name it as General --> Save & Close.

4. Development Activities

1. Creating Tasks 2. Creating Task Group 3. Creating Subject Area 4. Creating Execution Plans 5. Creating Schedules 6. Exporting & Importing(Deployment)

1. Creating Tasks:

It is a lowest object in DAC

In Informatica a work flow is equalent to Task

In one task we can map minimum one work flow and max is 2.

Process:

· Open DAC portal and provide user name and password. · Click on Design tab -> double click on Task -> click New -> provide

Name: Router

Command for incremental load: WKF_ROUTER

Command for Full load: WKF_ROUTER

Folder name: RRITEC

Primary source: ORCL_SCOTT_SCOURCE

Primary target: ORCL_B165TARGET_DW

Task phase: General


Execution type: Informatica

· Click on Save. · Right click on Task – Router -> click on Synchronize Task -> ok ->ok.

Similarly create one more task with name of Sorter and use workflow as W_SRT

2. Creating Task Groups.

Task group is mainly used to integrate n number of tasks.

In Task group we will configure dependency order of the task. This dependency order will be shown as Depth in Execution plan.

Dependency order smallest to highest will be running , If dependency order is same for 2 Tasks then both will run parallel.

Process:

· Click on Design tab -> double click on Task Groups -> new

Name: B165_TASKGROUP and Save.

· Click on Child task -> click Add/Remove -> select Router and Sorter -> click on Add -> ok

Under dependency order give 1 and 2 ->click on ok & Save.

3. Creating Subject Area

A Subject area is equalent to Business area or Data mart. (or)

A group of Tasks and Task groups are called as Subject area.

Ex: Loyalty, Marketing, Sales, Finance….

Process:

· Click on Design tab -> double click on Subject area -> new

Name: B165_SA -> Save.


· Click on Child task -> click Add/Remove -> select Router and Sorter, B165_TASKGROUP

Click on Add ->ok ->Save.

· Right click on Subject area -> click on Assemble -> ok -> Accept -> ok -> Save.

4. Creating Execution plan

It is used to integrate n number of Subject areas.

Process:

· Click on Execute Tab -> Execution Plans -> new

Name: B165_EP -> Save.

· Click on Subject Areas -> Add/Remove -> select B165_SA -> click Add -> ok ->Save

· Click on Parameters tab -> click Generate -> ok

Type Name Value Data Source ORCL_B165TARGET_DW ORCL_DW Data Source ORCL_SCOTT_SOURCE ORCL Folder RRITEC CUSTOM_RRITEC

Click on Save.

· Right click on Execution plan -> click on Build -> ok

Running Execution plan:

· Start the DAC server (start -> all programs -> DAC ->Start Server).

·


· Select B165_EP execution plan ->click on Run now->click on -> Yes ->ok · Go to Informatica Workflow monitor -> connect to our Repository and

observe that workflows are running.

Note: only one Execution plan is running at a time.

Scheduling:

· Click on Execute tab ->click Scheduler -> new · Provide name as B165_SC ->select Execution plan as B165_EP · Select Run only once -> give Start date as 3 min.. forward from current

time -> save

Note: The Execution time will be delay 10 – 60 sec.

Configuring Email:

Any change in the server status will be mailed to corresponding users.

Process:

Click Setup tab -> E-mail Recipients -> new -> provide

Name: RAM

E-mail: [email protected]

Click on Save.

5. Deployment:

Copying DAC Repository from one environment to another environment is called as Deployment.

Step1: Data Base Move.

DAC total work will be saved in backend schema what we configured (in lab it is DAC USER).

Step2: Exporting DAC Metadata (Taking Back up of DAC Repository)

· Go to Tools menu ->DAC Repository Management -> Export


· Select Rritec container ->click on Change Import & Export folder -> select Desktop ->create new folder and name it as DAC_BACKUP ->select it and click ok ->

· Select all the options under Categories -> under Application list select Rritec -> click ok -> ok.

(After few min.. Export process will be completed).

Step3: Importing

Once we can export in Development environment that we can import into testing server

· Go to Tools menu -> DAC Repository Management ->Import -> Select DAC_BACKUP folder ->ok.
