Parent topic: Basic Database Administration. You typically create a database during Oracle Database software iracle. However, how to spray paint can can also create a database after installation. You want to create another database and database instance on the same host computer as an existing Oracle database. In this case, this chapter assumes that the new database uses the same Oracle home as the existing database.
You eatabase also create the database in a new Oracle home by running OUI again. Parent topic: Creating and Configuring an Oracle Database. Database creation prepares several operating system files to work together as an Oracle Database. You only need to create a database once, regardless of how many data files it has or how many instances access it.
You can create a database to erase information in an existing database and create a what is thresholding in image processing database with the same name and physical structure.
Table lists some recommended actions:. Oracle Database Structure and Storage. Schema Objects. Plan the layout of the underlying operating system files your database will comprise. For example, you can place redo log files on separate disks or use striping. You can situate data files to reduce contention. And you can control data density number of rows to a data block.
If you create a Fast Recovery Area, Oracle recommends that you place it on a storage device that is different from that prompy the data files. To greatly simplify this planning task, consider using Oracle Managed Files and Automatic Storage Management to create and manage the operating system files that comprise your database storage. Using Oracle Managed Files. Oracle Database Performance Tuning Guide. Your Oracle operating ni documentation, including the appropriate Oracle Database installation guide.
Select the global database namewhich is the name and location of the database within the network structure. Familiarize yourself with the oeacle parameters contained in the initialization parameter file. Become familiar with the concept and operation of a server parameter file. I use what i got lyrics server parameter file lets you store and manage your initialization parameters persistently in a server-side disk file.
Oracle Database Reference. All character data, including data in the i dictionary, is stored in the database character set. You specify the database character set when you create the database.
See " About Selecting a Character Set " for details. Oracle Commznd Globalization Support Guide. Oracle Database uses one of two time zone files as the source of databasw time zones. Select the standard database block size. Additionally, you can specify up to four nonstandard block sizes what is the jingle ball creating tablespaces.
If you plan to store online redo log files on disks with a 4K byte sector size, determine whether you must manually specify redo log block size. Managing Undo. Consider whether you want to configure a read-only Oracle home or a read-write Oracle home for your database. Develop a backup and recovery strategy to protect the database from failure. It is important to protect the control file by multiplexing, to choose commanf appropriate backup mode, and to manage the online redo log and archived ceate log files.

Parent topic: Considerations Before Creating the Database.
It is important to select the right character set for your database. The Unicode standard is the universal character set that supports most of the currently spoken languages of crrate world. The use of the Unicode standard is indispensable for rceate multilingual technology, including database processing. After a database is created and accumulates production data, changing the database character set is a time consuming and complex project.
Therefore, it is very important to select the right character set at installation time. Even if the database does not currently store multilingual data but is expected to store multilingual data within a few years, the choice of AL32UTF8 for the database databasee set is usually the only good decision. The universality and flexibility of Prlmpt typically outweighs some additional cost associated with it, such as slightly slower text processing compared to single-byte character sets and higher storage space requirements for non-ASCII text compared to non-Unicode character sets.
If you do not want to use AL32UTF8, and you are not restricted in your choice by a vendor requirement, then Oracle suggests that you use one of the character sets listed as recommended for the database.
The recommended character sets were selected based on the requirements of modern client operating systems. In addition, the default database creation configuration in DBCA allows the selection of the recommended character sets only.
Do not use UTF8 as the database character set unless required for compatibility with Oracle Database clients and servers in Oracle8 i Release 1 8. Starting with Oracle Database 18c, you can simplify patching and mass rollouts of software across multiple database servers by deploying a read-only Oracle home as a software image. To configure an Oracle home in read-only mode, you first install Oracle Database software using a software-only deployment, and then configure it as a read-only Oracle home before you create the listener and the database.
Traditional read-write Oracle homes contain instance-specific files, so if you patch them, then you must patch each of them individually. Because of this configuration, you can use a read-only Oracle home as a software image that you can share across multiple database servers, because it stores only the static files.
This option simplifies patching and mass rollout, because when you want to distribute a patch to multiple database servers, you only need to update one Oracle home image.
This directory contains user-specific files, instance-specific files, and log files. This directory contains instance-specific dynamic files, such as configuration files.
The commwnd Oracle software must be ocmmand. This includes setting various environment variables unique to your operating system and establishing the directory structure for software and database files. Sufficient disk storage space must be available for the planned database on the computer that runs Oracle Database.
All of these are discussed in the Oracle Database Installation Guide specific to your operating system. If you use the Oracle Universal Installer, it will guide you through your installation and provide help in setting environment variables and establishing directory structure and authorizations.
Interactive mode provides a graphical interface and guided workflow for creating and configuring a database. One advantage of using this statement over using DBCA prmpt that you can create databases from within scripts.
You perform these actions by running the supplied scripts. If you have existing scripts for creating your database, what is a major in business administration consider editing those scripts to yow advantage of new Oracle Database features. The instructions in this section catabase to single-instance installations only.
Single-instance does not ro that only one Oracle instance can reside on a single host computer. In fact, multiple Oracle instances and their associated databases can run on a datqbase host computer. A single-instance database is a database that is accessed by only one Oracle instance at a time, coommand opposed to an Oracle RAC database, which is accessed concurrently by multiple Oracle instances on multiple nodes.
Starting in Oracle Database 12 c Release 2 This configuration is useful for the scalability of parallel queries. On some platforms, the SID is case-sensitive. It is common practice to set the SID to be equal to the database name. The maximum number of characters for the database name is eight.
Oracle Database Concepts for background information about the Oracle dstabase. You must be authenticated and granted appropriate system privileges in order to create a database. You can be authenticated as an administrator with the required privileges in the following ways:. To be authenticated with a password file, create the password hos as described in " Creating and Maintaining a Database Password File ". To be authenticated with operating system authentication, ensure that you log in hhow the host computer with a user account that is a member of the appropriate databass system user group.
On the Windows platform, the user installing the Oracle software is automatically placed datbaase the required user group. When an Oracle instance starts, it reads an initialization parameter file.
This file can be a text file, which can be created and modified with a text editor, or a binary file, which is created and dynamically modified by the database.
The binary file, which is preferred, is called commabd server parameter file. In this step, you create a text initialization parameter file. In a later step, you create a server parameter file from the text file.
One way to create the text initialization parameter file is to edit the sample presented in " Sample Initialization Parameter File ". If you create the initialization parameter file manually, ensure that it contains at least the parameters listed in Table All other parameters not listed have default values. Database identifier.
Creating a Database on Windows Using Database Configuration Assistant
May 15, · very simple create and delete of database using command line - PART 1. Set ORACLE_SID to the database service of the database whose contents you intend to export. For example, if the database you intend to export is starter database orcl, then enter the following at the command prompt. Note that there are no spaces around the equal sign (=) character. Here is the script used in the command prompt: SQL> connect testprojet as sysdba; Enter password: Connected. SQL> select * from testgeo; select * from testgeo * ERROR at line 1: ORA table or view does not exist EDIT.
Learn how to create a new database manually. As part of its database software files, Oracle Database provides a sample initialization parameter file, which can you can edit to suit your needs. You can choose to create database creation scripts using Oracle Database Configuration Assistant. Use Manual Database Creation Tasks to understand the manual tasks involved in creating a new database for each of these database creation categories.
Each step is explained in detail in the following subsections. An example in the following sections demonstrates how to create a database.
Then, delete the starter database orcl. Parent topic: Postinstallation Database Creation on Windows. You are required to export an existing database only if you intend to copy its contents to a new database. If you are working with data from an earlier Oracle release, then you can use Export for this task. If you are using Oracle Database 10 g Release 1 Although you can start Data Pump Export or Export in either the parameter mode or an interactive mode, Oracle recommends parameter mode.
Interactive mode provides less functionality than the parameter mode and exists for backward compatibility only. If you use the parameter mode, then Data Pump Export considers the file names and the directory names to be invalid if they contain one or more blank spaces. For example:. If Data Pump Export is used in an interactive mode, then the file name or the directory name can contain a space without quotation marks.
If you use the parameter mode, then Export considers the file names and the directory names to be invalid if they contain one or more blank spaces. If Export is used in an interactive mode, then the file name or the directory name can contain a space without quotation marks. You now have a full database export of the starter database orcl in the file myexp. All messages from Data Pump Export are logged in file myexp.
All messages from Export are logged in the file myexp. Parent topic: About Exporting an Existing Database. Deleting database files is required only when you copy an existing database to a new database to replace the old database. In the following example, you delete the database files of the starter database orcl.
Starting with Oracle9 i Release 2 9. This affects how Oracle Database interprets the parameter values in your initialization parameter file. Starting with release 9. Oracle highly recommends modifying your parameter files to remove such references and other methods of nesting quotation marks in the initialization parameter values.
If you do not have an existing database on your system, then you cannot copy an existing initialization parameter file to use as the basis for your new initialization parameter file. However, you can use the sample initialization parameter file initsmpl. This is the basis for the initialization parameter file for the database prod. If you use the initsmpl. Give a unique database name to each database.
You can use eight characters for a database name. The name is not required to match the SID of the database service. Ensure that you specify the complete path and the file name, including the drive letter.
The value of is used for this example. The ADR is used in problem diagnostics. Oracle Database Reference for information about other initialization parameters that you can add or modify. Before you create the database, first create a Windows service to run the database. This service is the Oracle Database process, oracle.
Note that the previously created initialization parameter file is specified, with complete path, including drive name. You can check if the service is started in the Services window of the Control Panel. When an Oracle wallet is created in the file system, only the user creating the wallet is granted access to that wallet by wallet creation tools.
Therefore, Oracle Database services running as the Windows User Account might not be able to access the wallet unless you explicitly grant access to the wallet using Windows tools. You must not specify the PFILE clause in this example, because the initialization parameter file is stored in the default location. At this point, there is no database. Only the System Global Area SGA is created and the background processes are started in preparation for the creation of a new database.
Unicode is suitable for storing text in practically any written language of the world. Oracle Managed Files eliminates the requirement to directly manage operating system files comprising an Oracle Database server, because you specify operations in terms of database objects rather than file names. Oracle Database Installation Guide for Microsoft Windows for more information about recommended database character sets. A list of all the Windows services currently running on the system appears.
If the database is successfully created, then the instance is started and the following message appears numerous times: Statement processed. Although you can start Data Pump Import or Import using either the parameter mode or the interactive mode, Oracle recommends the parameter mode because it provides more functionality. Interactive mode exists solely for backward compatibility. If you use the parameter mode, then Data Pump Import considers the file names and the directory names to be invalid if they contain one or more blank spaces.
If you use Data Pump Import in an interactive mode, then the file name or the directory name can contain a space without the quotation marks. If the original database from which the export file was generated contains a tablespace that is not in the new database, then Import tries to create that tablespace with associated data files.
The easy solution is to ensure that both the databases contain the same tablespaces. Data files are not required to be identical. Only the tablespace names are important. If this is the first database on your computer or if you intend to make the new database the default database, then you must make a change in the registry.
If anything goes wrong while operating the new database without a backup, then you must repeat the database creation procedure. Back up your database now to prevent loss of data. Although ORADIM returns the prompt immediately, you must wait for the database and the service to stop completely before continuing to Step 2. If you do not do this, then the backup is useless because it was taken while data was being written to data files. Database files consist of the initialization parameter file, control files, online redo log files, and data files.
When the backup is complete, you can start the database again, create users and objects, if necessary, make any other changes, and use the database. Back up the database after making any significant changes, such as switching into the archiving mode or adding a tablespace or a data file. Oracle Database Concepts. Do not store database files on a compressed drive.
Note: If you copy data from an existing database to the new database, select Yes; otherwise, No. Also, if you import tables and other objects from the existing database, select Yes; otherwise, No. About Exporting an Existing Database You are required to export an existing database only if you intend to copy its contents to a new database.
