Shared Server Mode— This mode allows several client connections to share a database-allocated pool of resources. Use this mode in configurations in which client load is expected to cause a strain on memory and other system resources. If you choose shared server mode, then you must indicate the number of server processes you want to create when a database instance is started.
For more information about setting this parameter, click Help. In this window, choose to use either the enhanced default security settings or the settings of a previous release, optionally disabling certain security features. The enhanced security settings include case-sensitive passwords. On this page you decide whether or not you want to enable the automatic maintenance tasks feature of Oracle Database 11 g.
Automated maintenance tasks are tasks that are started automatically at regular intervals to perform maintenance operations on the database. They are:. Automatic Optimizer Statistics Collection—Collects optimizer statistics for all schema objects in the database for which there are no statistics or only stale statistics. Automatic Segment Advisor—Identifies segments that have space available for reclamation, and makes recommendations on how to defragment those segments.
See Oracle Database Administrator's Guide for more information. In this window, a navigation tree displays the storage structure of your database control files, datafiles, redo log groups, and so forth.
If you are not satisfied with the storage structure or parameters, then you can make changes. Note that if you selected one of the preconfigured templates for a database, then you cannot add or remove control files, datafiles, or undo segments. Create Database —Select this option to create your database at this time. Save as a Database Template —Select this option to save the database definition as a template to use at a later time.
After you make your choice, click Finish. A confirmation window appears after a short period of time. Review the information, and click OK to proceed. You can also use DBCA to delete a database. When DBCA deletes a database, it shuts down the database instance and then deletes all database files.
On the Windows platform, it also deletes associated Windows services. In the Operations window, select Delete a Database and click Next.
Templates are used in DBCA to create new databases and duplicate existing databases. The information in templates includes database options, initialization parameters, and storage attributes for datafiles, tablespaces, control files, and online redo logs.
Templates can be used just like scripts, but they are more powerful than scripts because you have the option of duplicating a database.
Duplication saves time because you copy the files of an existing database, referred to as a seed database , to the correct locations. Easy duplication. By creating a template containing your database settings, you can easily create a duplicate database without specifying parameters twice.
This type of template contains both the structure and the physical datafiles of an existing database, referred to as the seed database. Your new database starts as a copy of the seed database, and requires only the following changes:. The datafiles for the seed database are stored in compressed RMAN backup format in a file with a. The seed database control file is stored in a file with. This type of template is used to create a new database.
It contains the characteristics of the database to be created. Nonseed templates are more flexible than their seed counterparts because all datafiles and online redo logs are created to your specification, and names, sizes, and other attributes can be changed as required. Users perform numerous, complex queries that process large volumes of data. Response time, accuracy, and availability are key issues. These queries SELECT statements range from a fetch of a few records to queries that sort thousands of records from many different tables.
Many concurrent users perform numerous transactions that require rapid access to data. Availability, speed, concurrency, and recoverability are key issues. This template allows you maximum flexibility in defining a database because you can change any of the settings for the database being created.
In the Operations window, select Manage Templates and click Next. In the Template Management window, select one of the following options, and click Next. Using an existing template, you can create a new template based on the predefined template settings.
You can add or change any template settings such as initialization parameters, storage parameters, or whether or not to use custom scripts. You can create a new template that contains structural information from an existing database, including database options, tablespaces, datafiles, and initialization parameters. User-defined schemas and their data will not be part of the created template. The source database can be either local or remote. Select this option when you want the new database to be structurally similar to the source database, but not contain the same data.
You can create a new template that has both the structural information and physical datafiles of an existing database. Databases created using such a template are identical to the source database. User-defined schemas and their data will be part of the created template. The source database must be local.
Select this option when you want a template from which you can create an exact replica of the source database. When creating templates from existing databases, you can translate file paths into Optimal Flexible Architecture OFA or maintain existing file paths. OFA is a set of file naming and placement guidelines for Oracle software and databases. Using OFA is recommended if the target computer on which you plan to create a database using the template has a different directory structure than computer on which the template was defined.
Standard file paths can be used if the target computer has a directory structure that is similar to the directory structure on the source computer. When you delete a template, it is no longer available to create a new database or a new template. In the Template Management window, select Delete a database template and click Next. Skip Headers.
Note: With Oracle Database, you typically have a single database that hosts more than one application. You do not need multiple databases to run multiple applications. Instead, you separate the objects that support each different application into different schemas in the same database.
However, there may be situations in which you want to create more than one Oracle database on the same host computer. When you do this with DBCA, the new databases typically use the same Oracle home directory as the first database, but store database data files separately from those of the first database.
Most windows provide default settings. Step 2 - Database Templates This window enables you to select the type of database that you want to create. Oracle ships templates for the following two workload types: General purpose or transaction processing Data warehouse Click Show Details to see the configuration for each type of database. Step 4 - Management Options Use this window to set up your database so it can be managed with Oracle Enterprise Manager.
Then, select one of the following options: If the Oracle Management Agent is installed on your host computer, then you can choose central management by selecting Register with Grid Control for centralized management and then selecting the Management Service. Step 6 - Storage Options In this window, specify the type of storage mechanism you would like your database to use.
Step 7 - Database File Locations In this window, specify the Oracle software home and the directory path in which to create the database files. Step 8 - Recovery Configuration When you create a new database, it is important to configure the database so you can recover your data in the event of a system failure.
