DAC Execution Plan Failure – “No active subject areas for execution plan”

When your Oracle Business Intelligence Applications (OBIA) DAC Execution Plan fails with a message that looks like this …

“Retrieving execution plan informationMESSAGE:::com.siebel.analytics.etl.execution.exceptions.EmptyExecutionPlanException: No active subject areas for execution plan were found
EXCEPTION CLASS::: com.siebel.analytics.etl.execution.ExecutionPlanInitializationException

com.siebel.analytics.etl.execution.ExecutionParameters.(ExecutionParameters.java:111)
com.siebel.analytics.etl.execution.ExecutionParameterHelper.(ExecutionParameterHelpe”

It is likely that you have a missing Subject Area in your Execution Plan in DAC.  You need to attach the Subject Area to the Execution Plan and rebuild the Plan.

After doing this your job should run successfully.

OBIA Financial Analytics – SIL_APTransactionFact_DiffManLoad performance issues

We are on Oracle Business Intelligence Applications (OBIA) 7.9.6.3 and had been experiencing performance issues with the SIL_APTransactionFact_DiffManLoad workflow/mapping. We tried a number of things but only had minimal improvements.   Eventually, I found a solution for the poor performance on Oracle Support.  This change resulted in a drastic improvement of this workflow.

The solution can be found on Oracle Support (http://support.oracle.com – Oracle Doc ID: 1446397.1), but for your convenience I have included the content below.  There are other mappings that have a similar problem.

OBIA 7963: SIL_APTransactionFact_Diffmanload Mapping And Performance Issue (Doc ID 1446397.1)

In this Document
Symptoms
Cause
Solution

 Applies to:
Informatica OEM PowerCenter ETL Server – Version 7.9.6.3 [AN 1900] and later Information in this document applies to any platform.

Symptoms
The OBIEE application (7.9.6.3) ETL task “SIL_APTransactionFact_DiffManLoad” has run over 68 hours during full load execution.

Cause

  1. The size of these columns (DOC_HEADER_TEXT and LINE_ITEM_TEXT )  in DAC is 255 (except AP where its 1020 in DAC and Infa). But in Informatica the size for these two columns is 1020. Ideally it should be 255. This is a known performance issue.
  2. The cause of the problem has been identified in unpublished  Bug 12412793- PSR: B16 INCREMENTAL: SIL_GLREVENUEFACT,

Solution
Below are the steps you will follow to modify the size of the fields in the lookup.

  1. Take a backup of existing Lookups ( LKP_W_AP_XACT_F and LKP_W_AR_XACT_F ).
  2. Login to Informatica Designer >Transformations
  3. Open the lookup and modify the size of the fields. The port lengths for the DOC_HEADER_TEXT and LINE_ITEM_TEXT were changed to 255 .
  4. Save the changes
  5. Rerun the test and confirm the performance issue is resolved  and migrate the changes in PROD.

Components of Oracle Business Intelligence Applications (OBIA)

The Oracle Business Intelligence Applications (OBIA) is made up of a number of components that are brought together to create a great prebuilt BI solution.  The components can be categorized into 4 major components.

1. Prebuilt reports and dashboard content + Embedded dashboard/report building tool
This prebuilt content is contained in the Oracle BI Presentation Services Catalog, and some of the content is built on the Oracle BI Repository metadata.
The tools include Dashboard Editor and Answers.

2. Prebuilt metadata content (Oracle BI Server Repository) + Administration Tool      
This metadata content is contained in the Oracle Business Intelligence Applications repository file (EnterpriseBusinessAnalytics.rpd).
This content is built and administered using the BI Administration Tool, and is built from the metadata in the OBAW.

3. Oracle Business Analytics Warehouse
The prebuilt data warehouse that holds data extracted, transformed, and loaded from the transactional sources.  The OBAW contains best-practice star-schemas and conforming dimensions.

4. Prebuilt ETL processes and tools
Prebuilt Informatica content + Embedded Informatica ETL Tool
+ Prebuilt DAC metadata repository files + Embedded DAC Tool
Informatica is a third-party application that performs the extract, transform, and load operations for the Data Warehouse.  The Informatica content includes Extract-Transform-Load (ETL) repository objects, such as mappings, sessions, and workflows, and is contained in the Informatica repository file (Oracle_BI_DW_Base.rep).
The DAC is a tool that is used for setup, configuration, administration, and monitoring of data warehouse processes.  The DAC content includes repository objects such as tables, subject areas, execution plans, and tasks, and is contained in XML files.
These tools and processes together extract data from sources, such as Oracle EBS or PeopleSoft, and load the data into the OBAW.
