Oracle9i Release 1 (9.0.1) New Features for Administration in Real Application Clusters

The Oracle9i release 1 (9.0.1) Real Application Clusters features and enhancements described in this section comprise the overall effort to simplify the Oracle cluster software administration process.

• Use the server parameter file to simplify parameter management in Real Application Clusters

  The server parameter file is easier to administer than the traditional client-side parameter files used in pre-9.0.1 releases.

  See Also: Chapter 2, "Parameter Management in Real Application Clusters Environments" for information about administering parameters in Real Application Clusters and for details on using client-side parameter files Oracle9i Real Application Clusters Installation and Configuration for details on configuring the server parameter file in Real Application Clusters

• Automatic undo management automatically controls undo space management

  Using automatic undo management simplifies your administrative duties by more efficiently using disk space to manage undo information.

• The Server Control Utility (SRVCTL) is fully documented; SRVCTL replaces OPSCTL

  SRVCTL is fully documented for use with Real Application Clusters databases.

• There are several usability enhancements to Recovery Manager that Real Application Clusters introduces

  The procedures for configuring Recovery Manager (RMAN) in Real Application Clusters databases are simplified. For example, use the CONFIGURE command to save channel allocation settings; you do not have to manually allocate channels. You can also configure RMAN to automatically backup your control file.

  You can execute a BACKUP ARCHIVELOG ... DELETE ALL INPUT command to delete the logs in all LOG_ARCHIVE_DEST_n locations. You can also execute commands such as BACKUP, RESTORE, and so on, directly from the RMAN prompt without having to use a RUN { ... } command.

  See Also: Part III, for more information configuring RMAN and backup and recovery using RMAN in Real Application Clusters

• The Oracle Database Configuration Assistant (DBCA) has Instance and Template Management features

  Use Instance Management to add or delete instances in a Real Application Clusters database. You can also use Template Management to manage database templates. For example, you can copy databases including the data files, or you can create a template from a database and move the template to another system and create a new database using that template.

• Default user names expire as of this release

Effective with the introduction of Real Application Clusters, all default usernames except SYS, SYSTEM, and SCOTT, expire upon install. To use these names, you must explicitly unlock them.
