Purpose
This tutorial illustrates how to merge and import objects from different repositories by using the Oracle Business Intelligence (BI)11g Administration Tool (Administration Tool). The three-way merge technique is examined by using two scenarios: three-way
merge with a common parent (also called the standard three-way merge) and three-way merge with no common parent(sometimes called the two-way merge).
Note: This tutorial is intended for learners who are familiar with the Administration Tool and have completed the Oracle byExample (OBE) tutorial, "Creating a Repository Using Oracle Business Intelligence Administration Tool 11g." It is alsorecommended that you complete the OBE, "Setting Up a Multiuser Development Environment by Using the Oracle BI 11gAdministration Tool" (located in the Business Intelligence section of the Oracle Learning Library) to understand how the mergeprocess occurs in a multiuser environment.
Time to Complete
Approximately 45 minutes
Overview
This tutorial provides step-by-step procedures for merging objects from different repositories by using the Administration Tool.
Scenario
In this tutorial, you initially review two different concepts for merging. You then practice these two concepts by performing astandard three-way merge and a three-way merge with no common parent.
Software Requirements
Following is a list of software requirements:
Oracle BI EE 11.1.1.5 or later must be installed along with the Sample Application schema (BISAMPLE) that is available for usewith Oracle Business Intelligence 11g. If you haven't installed the Sample Applications (825), you can install both the SampleApplication schema and repository from here.
SampleAppLite.rpd must be available on an accessible drive (local or network) as an alternate repository for merging. IfSampleAppLite.rpd is not available, you can unzip it from here and save it to\bifoundation\OracleBIServerComponent\coreappplication_obips1\repository (for
example,c:\bi11g\instances\instance3\bifoundation\OracleBIServerComponent\coreappplication_obips1\repository).

SampleAppLite is a lightweight version that ships with the Oracle BI EE Simple Install, while SampleApp is the full version
with many more examples and features.A text editor, such as MS Notepad or MS WordPad must be installed.
Note: Oracle BI Release 11g (11.1.1.5) automatically appends a numeric suffix to each version of the .rpd file. In this tutorial, the
repository is SampleApp_BI0009.rpd. Additionally, the SampleAppLite repository file also follows this version namingconvention (for example, SampleAppLite_BI0001.rpd).
Prerequisites
Before starting this tutorial, you should:
Have some familiarity with the Oracle BI 11g Administration ToolHave proper permissions for installing and configuring Oracle BI EE on your company's system
Note: Screen captures for this tutorial were taken in a Windows XP Professional environment; therefore, Start menu options andcolors may vary.
Examining Merge Scenarios
The Oracle BI Repository development process is conceptually identical to the classic Software Configuration Management (SCM)three-way merge, in that changes are managed by merge and reconciliation in a multiuser development environment (MUDE). The
Oracle BI Repository is stored as an .rpd file. Changes are managed by using the Administration Tool. Developers check out thefile and make changes locally. Then, these changes are reconciled and merged into the master repository. To read a moredetailed description and view an image of the merge process, click this link. Please note that this process is covered in detail inthe OBE,"Setting Up a Multiuser Development Environment by Using the Oracle BI 11g Administration Tool" (located in theBusiness Intelligence section of the Oracle Learning Library).
However, as an administrator, you may want to manually merge the changes from multiple repositories or import objects from
different repositories outside of the MUDE. Oracle BI EE offers inherent support for the classic three-way merge inside and outsidethe MUDE. The two main scenarios (outside of the MUDE) are discussed in this tutorial.
Describing Merge Types
Describing Merge Types
The two merge types discussed in this tutorial are presented below:
1 . Standard three-way merge (three-way merge with a common parent): This merge is useful when you have acommon parent repository and two derived repositories.
For example, you may have development and production repositories, both derived from a common parent
repository. You may want to import or merge the changes from the development repository into the production
repository. The three-way merge process, as indicated in the diagram to the right, depicts the Parent RPD, andtwo derived RPDsRPD A and RPD B. After the merge, a fourth merged repository file, Merged RPD, is created.
Note that modified or new objects are listed with an asterisk (*).
In RPD A, the object, Obj1, is modified, and a new object, NewObjX, is created. Similarly, a new object, NewObjB,
is created in RPD B. When these two repositories are merged, the merged repository contains obj1 (inheritedfrom the parent and modified in RPD A), and also the new objects (NewObjX and NewObjB ) from both
repositories.

2 . Three-way merge with no common parent: This is a special case formerging, where you are merging objects from two different
repositories with no common parent.
For example, as an administrator, you may want to import objects,
such as subject areas or folders, from a different repository into yourcurrent or working repository. In this particular case, the repositories
to be merged do not have a common parentthis scenario isdepicted in the diagram to the right.
Both repositories are treated differently. Conflicting object names areduplicated while merging or importing. A suffix #n is appended
(where #n is a variable number). RPD A and RPD B are treated as
separate repositories and are compared to a blank repository
(representing no common parent). The merging process will not
overwrite Obj1; instead, both copies of Obj1 (Obj1 and, Obj1#1*)from RPD A and RPD B are retained in the merged repository. Also
note that new objects from both repositories (NewObjB* andNewObjX*) are created in the merged repository.
Merging Objects from Different Repositories with a Common Parent (Standard Three-WayMerge)
In the scenario within this topic, you have a development (or current) repository in which you are working. A modified repository in
which the changes are made is also present. Both these repositories are derived from the same parent.
To compare these two repositories against the original repository and merge your changes to create a fourth merged repositoryfile, perform the following steps:
1 . Create copies with which to work. Navigate to
\bifoundation\OracleBIServerComponent\coreappplication_obips1\repository (for example,
c:\bi11g\instances\instance3\bifoundation\OracleBIServerComponent\coreappplication_obips1\repository)
and select the SampleApp repository (for example, SampleApp_BI0009.rpd).

Merging Objects from Different Repositories Without a Common Parent (Two-Way Merge)
Although there are numerous scenarios for this technique, a simple scenario of importing new objects from two different
repositories is employed in this topic. Initially, you create a blank repository (this simulates that there isn't a parent), and then you
merge the objects from two different repositoriesSampleApp_BI0009.rpd and SampleApp Lite.rpd.
To merge these two repositories and to create a new merged repository file, perform the following steps:
1 . Create a blank repository in offline mode by using the Administration Tool. This is a one-time process.
Click Start > All Programs > Oracle Business Intelligence > BI Administration. The Administration Tool appears.
