OBIEE Architecture Design based on type of Installation:
The Oracle Business Intelligence 11g logical
architecture comprises a single integrated set of manageable components which
can be installed and configured to work together on a single host or can be clustered
across multiple hosts for performance and availability
3 Types
of Installation are available:
• Simple
Install
Purpose: Demonstration and Evaluation Single-User Development
Definition: Installation with the default settings on a single
computer in the minimum number of steps.
Managed Server is not installed.
Mainly used for demonstration, or PoC
• Enterprise
Install
Purpose:
Enterprise Deployment for Hosted Development and Production
Definition
: Enterprise Install type enables you to specify several more
configuration settings than the simple
• Software
Only Install
Purpose: Enterprise Deployment for Highest Levels of Availability
and Security
Definition: Installation of the binary files in Middleware home
and useful if you want to have multiple domains or products share a common
Middleware Home
Oracle
Business Intelligence Components :
• Java
Components (WebLogic Domain)
– Deployed as JEE
applications
– To service
SOAP, HTTP, and other forms of requests
• System
Components (BI Instance)
– Deployed as
server processes
– Provide the
core services that enable OBI
• Other
Domain Contents
– Includes all
the necessary software, metadata, configuration files, RPD files, Oracle BI
Presentation Catalog, and connection and database configuration information
that are
required to run an Oracle Business Intelligence system.
They are
managed mainly by 2 administrative user interface :
WebLogic Server Administration Console — which provides
advanced management for Weblogic, Java components (BI Publisher,
MapViewer, …), and security. Fusion Middleware Control (Enterprise Manager) — which is used to manage the system components (C++, JSE) (BI Server, BI Presentation Services, Scheduler, ….)
Oracle
Business Intelligence Components:
Administration
Server
Components for administering the
system are :
• Web
Logic Server Administration Console
– Monitoring the
health and performance of JEE servers
– Configuring
WebLogic server domains
– Stopping and
starting JEE servers
– Viewing JEE
server logs
– Managing users
in the LDAP Server of the WebLogic Server
• Fusion
Middleware Control
– Starting,
stopping, and restarting all system components
– Scaling out of
system components
– Managing
performance and monitoring system metrics
– Performing
diagnostics and logging
• JMX
Mbeans
– Provides programmatic access for
managing a BI domain
Managed
Server and Node Manager
• Managed
Server
Provides run-time environment
for the Java-based services and applications within the system
• Node
Manager
Process management services for
the Administration Server and Managed Server processes
Managed
Server Components
• Oracle
BI Presentation Services Plug-in
– Routes HTTP and
SOAP requests to Oracle BI Presentation Services
• Oracle
BI Action Services
– Web services
required by the Action Framework
• Oracle
BI Security Services
– Integration of
the Oracle BI Server with the Oracle Fusion Middleware security platform
• Oracle
BI Publisher
– Enterprise
reporting solution for authoring, managing, and delivering all types of highly
formatted documents
• Oracle
Real-Time Decisions (Oracle RTD)
– Analytics
software solutions allowing companies to make better decisions in real time
• Oracle
BI SOA Services
– Invoke OBI functionality from
Business Process Execution Language (BPEL) processes
System
Components
System components are deployed
as non-JEE components (C++ and J2SE)
• Oracle BI Server
– Query and data access
capabilities at the centre of OBI
– Provides services for
accessing and managing the enterprise semantic model. Also RPD resides here
• Oracle BI Presentation Services
– Framework and interface for
the presentation of BI data to Web clients
• Oracle BI Scheduler
– Scheduling for analyses to be
delivered to users at specified times
• Oracle BI JavaHost
– Supports various components
such as Java tasks for Oracle BI Scheduler,Oracle BI Publisher, and graph generation
– Also enables Oracle BI Server
query access to Hyperion Financial Management and
Oracle OLAP data sources
• Oracle BI Cluster Controller
– Distributes requests to the BI
Server
–
Ensuring
requests are evenly load-balanced across all BI Server process in the BI Domain
Oracle
Process Manager and Notification Server (OPMN)
•
OPMN
– Manage system
components for Oracle Business Intelligence (for advanced users)
– Supports both
local and distributed process management
• OPMN
and Fusion Middleware Control
– Fusion
Middleware Control is the recommended approach for starting, stopping,
and viewing the status of
components
– OPMN is suitable only for advanced
users
Basic Directory
Structure of OBIEE :
•
WebLogic Server home
– WebLogic Server
home
– Contains Java
components
• User
Projects
– contains
product domains (including one or more Oracle Business Intelligence domains),
Administration Server, and one
or more Managed Servers
• Oracle
BI Home
– Contains all the binary files
(read-only) that are specific to Oracle Business Intelligence
Some Useful
Directories of the BI Instance:
•
Repository
–
%Middleware Home%\instances\instance1\bifoundation\OracleBIServerComponent\
coreapplication_obis1\repository
•
Web Catalog
–
%Middleware Home%\instances\instance1\bifoundation\OracleBIPresentationServerComponent\
coreapplication_obis1\catalog
•
NQSConfig.ini
–
%Middleware Home%\instances\instance1\config\OracleBIServerComponent\
coreapplication_obis1\repository
•
instanceconfig.ini
–
%Middleware
Home%\instances\instance1\config\OracleBIPresentationServerComponent\
coreapplication_obis1\catalog
•
BI Server Logs (nqserver.log, nqquery.log)
–
%Middleware Home%\instances\instance1\diagnostics\logs\OracleBIPresentationServerComponent\
coreapplication_obis1
