New Features for Oracle Real Application Clusters 18c

New features for Oracle Real Application Clusters for 18c.

• Simplified Image-based Oracle Database Installation

  Starting with Oracle Database 18c, the Oracle Database software is available as an image file for download and installation. Extract the image software into the directory where you want your Oracle home to be located, and then run the setup.exe script to start the Oracle Database installation.

  For more information, see About Image-Based Oracle Database Installation

• Read-Only Oracle Home

  Starting with Oracle Database 18c, if you choose a read-only Oracle home, then the database tools and processes write under the ORACLE_BASE_HOME path instead of under the Oracle home directory.

  A read-only Oracle home separates the software from the database configuration information and log files. This separation enables you to easily share the software across different deployments. A read-only Oracle home also simplifies version control and standardization.

  For more information, see Configuring Read-Only Oracle Homes

Desupport of Oracle Administration Assistant Tool for Windows

Oracle Administration Assistant also enabled database services, startup and shutdown configurations, and Windows Registry parameter management. There is no replacement.
