Oracle RTD is supported on both Windows and UNIX platforms, and runs on Oracle WebLogic and IBM WebSphere application servers. For detailed information about supported platforms, refer to Oracle Real-Time Decisions System Requirements and Supported Platforms for Version 3.2.
This chapter contains the following topics:
Oracle RTD is a real-time decision engine software platform that consists of the following components:
Real-Time Decision Server
Decision Studio
Decision Center
Load Generator
Administration (JMX)
Real-Time Decision Server can be installed on either Windows or UNIX platforms. Decision Studio and Load Generator are client components that can only run on Windows.
Real-Time Decision Server requires its own database, called the Oracle RTD Database, to store objects and metadata for inline services created in Decision Studio.
To install Oracle RTD, you need to:
Install the database server, and if required by your chosen application server, a Java Development Kit.
Install files for the Real-Time Decision Server and Oracle RTD clients, and create and initialize the database.
Install the application server of your choice.
Configure the data source for the Oracle RTD Database.
Deploy and configure Real-Time Decision Server using the administration console for your application server, and other tools.
Configure authentication settings.
Set up access to enterprise data sources.
Install the database server you want to use as the Oracle RTD Database. This database must be one of the following: Oracle Database or Microsoft SQL Server. For information about database installation, refer to your database documentation. For detailed information about supported database versions, refer to Oracle Real-Time Decisions System Requirements and Supported Platforms for Version 3.2, available from the Oracle RTD Documentation Web site at:
http://www.oracle.com/technetwork/middleware/real-time-decisions/documentation/index.html
Note the following:
If you are using SQL Server, you may install your database server either as the default (unnamed) instance or as a named instance.
If you are using Oracle Database, you must install the user_lock package. Refer to the Oracle Database documentation for information about installing optional Oracle packages.
You can install your database server on the same computer where you plan to install Oracle RTD, or on a different computer.
Real-Time Decision Server runs on one of the following application servers: WebSphere or WebLogic. For detailed information about supported application server versions, refer to Oracle Real-Time Decisions System Requirements and Supported Platforms for Version 3.2, available from the Oracle RTD Documentation Web site at:
http://www.oracle.com/technetwork/middleware/real-time-decisions/For instdocumentation/index.html
Note:
For up to date information on specific versions of your application server, read all references to that application server in Oracle Real-Time Decisions Release Notes.
For WebLogic systems, see Chapter 3, "Installing and Configuring WebLogic for Oracle Real-Time Decisions."
For WebSphere systems, see Chapter 4, "Installing and Configuring WebSphere for Oracle Real-Time Decisions."
WebLogic and WebSphere install their own JDK.
For client tools (Decision Studio, Load Generator, SDDBTool and JConsole), you must install a 32-bit JDK. Create a system environment variable called JAVA_HOME and set its value to the full path name of the install location of the JDK.
Modify the system environment variable PATH by adding %JAVA_HOME%\bin; to the beginning of the existing value.
For example, if the existing PATH value is abc;', then the new value should be:
'%JAVA_HOME%\bin;abc;'
Close all open applications before you install Oracle RTD. In particular, shut down any applications or processes that use port 8080, the default Oracle RTD port. In addition, shut down any real-time indexing software, such as Google Desktop, before installing Oracle RTD. Running real-time indexing software on the computer where Real-Time Decision Server is running can adversely impact Oracle RTD performance.
