•Oracle BI and DW Partner
•Innovation leader in Oracle BI
•Over 100 consultants worldwide
•Offices in US (Atlanta), Europe,

•Skills in broad range of supporting
Oracle BI Tools
‣OBIEE, Exalytics and OBIA
‣ODI, EDQ, OWB
‣Essbase and Oracle OLAP
‣GoldenGate
‣Exadata
‣Endeca

Presentation Agenda
•Take a look at OBIEE Multi-User Development
Environment (MUDE)
•Understand MDS XML: what it is… why do we care?
•Investigate Git, our sample version control system
•See manage_rpd.pl: a Perl script for automating some
basic tasks
•A demo of repository development using the Admin
Tool and Git.
•(Optional) Discuss enterprise SCM deployments

Repository Software Development Lifecycle (SDLC) Challenges
• Allow multiple users to develop
concurrently
‣Serialized
‣Non-serialized
• Version control of repository
‣Providing “rollback” capabilities
‣Never develop the same “code” twice
• Package up releases
‣Allow easy migration between
environments
‣Provide the ability to version the
entire BI project

Completed MUDE Project Checkout
In the Master directory
‣gcbc.rpd: The original master RPD file
‣gcbc.000: A backup file for rollback
purposes
‣gcbc.mhl: The history file (can be
converted to an XML file using
mhlconverter)
!
In the Repositories directory
‣gcbc_project1.rpd: The subset RPD
file
‣originalgcbc_project1: Another copy
of the subset RPD file for doing 3-way
merges

MUDE Development: Viewing MUD History

“Metadata-only” Multi-User Development
•Merging is done by the
developer instead of a
“source master”
•The master repository is not
itself checked into version
control
•Siloed merging and
branching
•Doesn’t version entire BI
project

The MDS XML Repository Storage Format
•New in OBIEE 11.1.1.6
•Like XUDML, but individual documents
for first-class repository objects
•Binary repository files are still required
for the BI Server
‣Generated by the Admin Tool
‣Generated by validaterpd command-
line utility
‣NOTE: Don’t use biserverxmlexec
command-line utility
•Integration with version control systems
built into the Admin Tool

Who Said This?
“The primary purpose of this new storage format
and the source control extensions in the Oracle
BI Administration tool is to permit fine-grained
tracking and recording of changes to objects in
a single repository. It is not a replacement for
the Multiuser Development Environment, as it
does not have any features for merge conflict
resolution, which instead would need to be
performed using the source control client tools.”

MDS XML: Choosing an Install Type
Client Installation
Using the Administration
Tool to do standalone
development

Enterprise Installation
Separate containers for Admin
and Managed Servers

Simple Installation
Single Container uses a smaller
footprint for laptops and VMs

MDS XML: Full Development Environment (Simple Install)
•RPD Development requires a BI Server
‣See the BI Server Intelligent Request
Generation
‣See SQL or MDX Generation
•RPD Development requires a query
tool
‣Something to query the BI Server
‣Presentation Server works well
•RPD Development requires data
visualization
‣OBIEE just so happens to have that

What Do We Think?
•MUDE provides more granular control over individual
repository objects
‣Multiple changes to the same physical file are supported
‣XML/Git can do the same using built-in Admin Tool
utilities
•XML/Git allows us to use a common framework for all our
BI Content in one central store
‣presentation catalog, ODI Content, database scripts
‣We can periodically check-in the MUDE master RPD
and history file to Git as well
•Was Mark Rittman right?
