Oracle9i Release 2 New Features for Real Application Clusters Setup and Configuration

• New Tablespace Requirements

  There are two new tablespaces required for this release: the XML tablespace to accommodate the XML DB features and the ODM tablespace to accommodate the Oracle Data Mining features.

• Oracle Universal Installer Enhancements
  • The Installer propagates local inventory to the remote cluster nodes. Therefore, you can perform deinstalls and patch installs from any node in the cluster.
  • Error messages are cluster-aware.
  • Registry operations in the Installer are clusterized for Windows NT and Windows 2000 platforms.
  • The order and composition of some Installer screens have changed and a Summary page displays the names of the nodes on which an operation is performed.
  • On a machine where you are installing Oracle for the first time, the Installer asks you to run the root script for the creation of the instLoc file on all the cluster nodes.
  • On UNIX platforms, the Installer displays a message asking you to run the root.sh script on the selected cluster nodes.
• Database Configuration Assistant Enhancements
  • On some platforms you can use cluster file system files to store datafiles for your cluster database.
  • You can specify the raw devices for datafiles in a text file and provide it as an argument to the Database Configuration Assistant. You can also place the SRVM Configuration Repository on a cluster file system.
  • You can customize thread assignments to database objects. For example, you can customize the default undo tablespace-to-instance assignment and redo log group files-to-instance thread assignment on the DBCA Storage page.
  • The DBCA displays an Instance Management summary page that shows the attributes of the instance to be added or deleted.
  • You can install multiple instances on a single node.
  • You can perform Instance Management operations, such as instance addition and deletion, using any active instance in your cluster database.
  • You can use Instance Management in non-interactive silent mode so that all input is provided through command line arguments.
  • When an operation fails, the DBCA reverses partially completed operations to restore the system to its previous state.
• Server Management Architecture Enhancements
  • You can use one gsdctl command syntax on all platforms to install, start, stop, and check the status of the GSD.
• Database Upgrade Assistant Enhancements
  • The Database Migration Assistant has been renamed the Database Upgrade Assistant (DUA). In addition, the DUA is fully functional to upgrade your pre-release 2 (9.2) Oracle cluster database to Oracle9i Real Application Clusters release 2 (9.2).
• Dynamic Support for Local and Remote Listener Parameters
  • You can use the ALTER SYSTEM SET SQL statement to dynamically update the LOCAL_LISTENER and REMOTE_LISTENER initialization parameters. Oracle also dynamically updates these parameters when you add or delete nodes from your cluster database. When Oracle updates these parameters, the PMON process registers the new information with the listener.
