Editor's Notes

  • #4: Planning the Database It is important to plan how the logical storage structure of the database will affect system performance and various database management operations. For example, before creating any tablespaces for your database, you should know how many data files will make up the tablespace, what type of information will be stored in each tablespace, and on which disk drives the data files will be physically stored. When planning the overall logical storage of the database structure, take into account the effects that this structure will have when the database is actually created and running. You may have database objects that have special storage requirements due to type or size. In distributed database environments, this planning stage is extremely important. The physical location of frequently accessed data dramatically affects application performance. During the planning stage, develop a backup strategy for the database. You can alter the logical storage structure or design of the database to improve backup efficiency. Backup strategies are introduced in a later lesson. These are the types of questions and considerations, which you will encounter as a DBA, and this course (in its entirety) is designed to help you answer them.
  • #5: Databases: Examples Different types of databases have their own specific instance and storage requirements. Your Oracle database software includes templates for the creation of these different types of databases. Characteristics of these examples are the following: Data Warehouse: Store data for long periods and retrieve them in read operations. Transaction Processing: Accommodate many, but usually small, transactions. General Purpose: Work with transactions and store them for a medium length of time.
  • #6: Oracle Database 10g: Administration Workshop I 3-<number> Database Configuration Assistant (DBCA) You can use the Database Configuration Assistant (DBCA) to create, change the configuration of, or delete a database. You can also create a database from a list of predefined templates or use an existing database as a sample to create a new database or template. This is sometimes referred to as “database cloning.” You can invoke the DBCA by performing the following steps: 1.Log on to your computer as a member of the administrative group that is authorized to install the Oracle software. 2.If required, set environment variables. 3.Enter dbca to invoke the DBCA. 4.Click Next to continue. DBCA offers you a choice of assisting with several operations, for example, creating a database.
  • #7: Oracle Database 10g: Administration Workshop I 3-<number> Using the DBCA to Create a Database You can use the DBCA to create a database as follows: 1.Select Create a Database on the DBCA Operations page to invoke a wizard that enables you to configure and create a database. The wizard prompts you to provide configuration information as outlined in the steps that follow. On most pages, the wizard provides a default setting that you can accept. 2.Select the type of database template to be used in creating the database. There are templates for Data Warehouse, General Purpose, and Transaction Processing databases that copy a preconfigured database, including data files. These data files include control files, redo log files, and data files for various included tablespaces. Click Show Details to see the configuration for each type of database. For more complex environments, you may want to select the Custom Database option.
  • #8: Oracle Database 10g: Administration Workshop I 3-<number> Using the DBCA to Create a Database (continued) 3.Database Identification: Enter the Global Database Name in the form database_name.domain_name, and the system identifier (SID). The SID defaults to the database name and uniquely identifies the instance associated with the database. 4.Management Options: Use this page to set up your database so that it can be managed with Oracle Enterprise Manager. Select the default: Configure the Database with Enterprise Manager.
  • #9: Oracle Database 10g: Administration Workshop I 3-<number> Using the DBCA to Create a Database (continued) 5.Database Credentials: Use this page to specify the passwords for the administrative accounts, such as SYS and SYSTEM. In class, use oracle as password for all administrative accounts. 6.Storage Options: Specify the type of storage mechanism (such as File System) that you would want your database to use. 7.Database File Locations: Choose according to your needs. Oracle Managed Files (OMF) eliminate the need for you to directly manage the operating system files comprising an Oracle database. You specify operations in terms of database objects rather than file names. For more details, see the lesson titled “Managing Database Storage Structures.”
  • #10: Oracle Database 10g: Administration Workshop I 3-<number> Using the DBCA to Create a Database (continued) 8.Recovery Configuration: If required, specify a flash recovery area and enable archiving. 9.Database Content: These pages provide options for selecting components, such as Sample Schemas, and for using custom scripts.
  • #11: Oracle Database 10g: Administration Workshop I 3-<number> Using the DBCA to Create a Database (continued) 10.Initialization Parameters: The tabs on this page provide access to pages that enable you to change default initialization parameter settings: Memory: Use this page to set the initialization parameters that control memory usage. Use either (A) Typical or (B) Custom memory allocation. Sizing: To specify block size, enter the size in bytes or accept the default. Character Sets: Use this page to specify the character sets for your database. Best Practice Tip: Oracle recommends (whenever possible) that you use Unicode for a database character set because it provides optimal flexibility for supporting Web technologies as well as many spoken languages. Connection Mode: Select Dedicated or Shared Server Mode. For more details, see the lesson titled “Configuring the Oracle Network Environment.” Note: Several initialization parameters are set for the lifetime of a database, such as the DB_BLOCK_SIZE and CHARACTER_SET parameters.
  • #12: Oracle Database 10g: Administration Workshop I 3-<number> Using the DBCA to Create a Database (continued) 11.Database Storage: If you have selected one of the preconfigured templates for a database, then you cannot add or remove control files or data files. Note: You may want to save your database definition as an HTML file for easy reference. 12.Creation Options: You have the options of creating your database at this time, saving the database definition as a template, and generating scripts. If you choose all options, then the DBCA first saves the database template, then generates the scripts into your destination directory, and finally creates your database.
  • #13: Password Management After the DBCA finishes, note the following information for future reference: Location of installation log files (see A) Global database name (see B) System identifier (SID) (see B) Server parameter file name and location (see B) Enterprise Manager URL (see C) Click Password Management to unlock database accounts that you plan to use. Provide a password when you unlock an account.
  • #14: Creating a Database Design Template A template is a predefined database definition that you use as a starting point for a new database. If you do not create a template as part of the database creation process, you can do it anytime by invoking the DBCA. You have three ways to create a template: From an existing template From an existing database (structure only) From an existing database (structure as well as data) The DBCA guides you through the steps to create a database design template.
  • #15: Using the DBCA to Delete a Database To delete (or configure) a database in UNIX or Linux, you must set ORACLE_SID in the shell from which DBCA is launched. Start the DBCA by entering dbca in a terminal window, and click Next on the Welcome page. To delete the database, perform the following steps: 1.On the Operations page, select Delete a Database, and click Next. 2.Select the database that you want to delete (in class, hist), and click Finish. 3.Click Yes to confirm your deletion.
  • #16: Oracle Database 10g: Administration Workshop I 3-<number> Using the DBCA to Delete a Database (continued) Dropping a database involves removing its data files, redo log files, control files, and initialization parameter files. The DROP DATABASE statement deletes all control files and all other database files listed in the control file. To use the DROP DATABASE statement successfully, all the following conditions must apply: The database must be mounted and closed. The database must be mounted exclusively—not in shared mode. The database must be mounted as RESTRICTED. An example of this statement is: DROP DATABASE; The DROP DATABASE statement has no effect on archived log files nor does it have any effect on copies or backups of the database. It is best to use Recovery Manager (RMAN) to delete such files. If the database is on raw disks, then the actual raw disk special files are not deleted.
