8.1 Simplified Image-Based Oracle Database Installation
Starting with Oracle Database 18c, installation and configuration of Oracle Database software is simplified with image-based installation.
Starting with Oracle Database 18c, the Oracle Database software is available as an image file for download and installation. You must extract the image software into the directory where you want your Oracle home to be located, and then run the
runInstaller script to start the Oracle Database installation. For details, refer to your operating system platform Oracle Database Installation Guide.
You must extract the image software (
db_home.zip) into the directory where you want your Oracle Database home to be located, and then run the
runInstaller script to start the Oracle Database installation and configuration. Oracle recommends that the Oracle home directory path you create is in compliance with the Oracle Optimal Flexible Architecture recommendations.
8.2 Terminal Release of Oracle Streams
Oracle Database 18c is the terminal release for support of the Oracle Streams feature. Oracle Streams will be desupported from Oracle Database 19 onwards.
Oracle Streams was deprecated in Oracle Database 12c (12.1). It does not support features introduced in Database version 12.1 and later releases, including the multitenant architecture, the LONG VARCHAR data type, long identifiers, and other features. Oracle GoldenGate is the replication solution for Oracle Database.
