I have found the following note from one of obiee 11g Installation document and thought of sharing as important key note and also after installation create necessary ENVIRONMENT variables to avoid ambiguity as taught by my guru(Madan Thota).
Prerequisites for Software Only Installation on 64-Bit Platforms:
Prior to Oracle Business Intelligence software only installation, you must install the latest Oracle WebLogic Server wls1033_generic.jar in MW_Home with 64-bit JDK. Then install Oracle Business Intelligence in the same MW_Home.
Supported Installation Types for Oracle Business Intelligence on 64-Bit Platforms
Different types of installation options available for Oracle Business Intelligence are as follows:
- Simple Install:
This installs 32-bit JVM and 32-bit Oracle WebLogic Server. Oracle Business Intelligence Server is a 64-bit system on 64-bit platforms. Simple Install is supported on the following 64-bit Platforms only:
- Linux x86-64
- Windows x86-64
However, for production the recommended installation type is software only install with 64-bit Oracle WebLogic Server and 64-bit JDK.
- Software Only Install:
This installs software binary files in an Oracle home for later configuration as part of the Oracle Fusion Middleware deployment process. This installation type is required if you want to install Oracle Business Intelligence with a 64-bit JVM on a supported 64-bit operating system.
Recommended installation steps for 64-bit platforms are as follows:
- Install 64-bit Oracle WebLogic Server with 64-bit JDK.
- Choose Oracle Business Intelligence Software Only Install option.
- Once software only install process is complete, select Configure.
- Enterprise Install:
This installation type is not supported when installing with a 64-bit JVM on a supported 64-bit operating system. Instead, select the Software Only Install type option.
For details, refer “Software Only Install” in Oracle Fusion Middleware Installation Guide for Oracle Business Intelligence.
Considerations and Limitations of Enterprise Install Type for Scaling Out Existing Installations
To scale out an existing installation with a 64-bit JVM on a supported 64-bit operating system, do not select the Enterprise Install type option. Select the Software Only Install type instead.
For details,refer “Software Only Install” in Oracle Fusion Middleware Installation Guide for Oracle Business Intelligence.
